Building Materials Terms
Seals the bottom of an exterior door, preventing drafts, water, noise, light and insects.
Usually made of aluminum extrusions with vinyl flaps.
Screws into the lower part of the door.
Some types lift automatically when the door is raised.
Another type is an aluminum extrusion with a rain-drip flange to prevent the flow of water off a door from collecting on a threshold and flowing under a door.
Another type is an adhesive-backed plastic door sweep.
Used to seal the sides and top of a door to shut out drafts and insects.
Available in a variety of forms, including roll-formed and extruded aluminum with vinyl bulbs or flaps.
Weather stripping that cushions as it seals.
Can be used in places with warping or irregularities.
Temporarily fills large gaps around windows.
Consists of soft, rope-like strands of weather strip with the consistency of modeling clay.
Easily applied by hand and remains pliable so it can be removed when the weather warms.
Paintable and will not harden or dry out.
Once the door is closed, the open ends of the V shape close together, with one end of the V touching the door and the other adhered to the door.
Forms an airtight seal.
Spring-metal tension strips are more difficult to install than adhesive-backed tension strips made of vinyl, but are the best permanent type.
Installed by pressing into position and sticking permanently.
Requires no nails or tools.
One type, pressure-sensitive sponge rubber tape, is suited for larger problem areas.
Another type, pressure-sensitive vinyl foam or felt, is for average sealing.
Closed-cell PVC foam compresses to fill irregular gaps and can be used outdoors.
Open-cell foam is for inside use only.
High-density foam is extremely durable and long lasting.
Least expensive type of weather stripping, but also has the shortest life.
Installs by gluing, nailing or stapling to the frame or molding around doors so the door will close snugly and quietly against it.
A good choice when appearance is no concern.
Available in a variety of widths, thicknesses and quality.
Reinforced felt weather strip is sturdier and designed to last longer.
For insulating water pipes from freezing in the winter. It also helps control heat loss when pipes carry hot water and controls condensation and dripping. Available in preformed insulating tubes that fit over the pipe.
Another type comes in batt form, which can be wrapped around the pipe.
One type is made of foil and poly to trap air between the sheets of foil, generally using bubble pack. A second type expands when installed between stud spaces. The resistance to heat flow depends on the heat flow direction. This type of insulation is most effective in reducing downward heat flow.
Comes in long rolls of various widths.
May be used in conjunction with many different building materials and cut to fit any shape.
Typically installed between roof rafters, floor joists or wall studs.
When a single reflective surface is used alone and faces an open space such as an attic, then it is called a radiant barrier.
Installs similar to foam insulation, but comes in an aerosol can and is best for do-it-yourself use. Best used for permanently sealing irregular gaps around the home, such as plumbing feed-thrus, electrical outlets, vents, etc.
After curing, it can be trimmed, sanded and painted.
When installing, only fill the area about 33 percent and the expanding foam will fill and seal the rest of the area.
Formulations include triple-expanding for general-purpose sealing and insulating; minimal-expanding for windows and door frames; and fast drying for multi-step projects such as filling a crack before painting.
Wear gloves and eye protection when applying.
Remove wet foam with acetone or acetone-based nail polish remover. Cured foam is difficult to remove from skin and clothes.
Comes in a liquid spray form that quickly foams and hardens. May have a higher insulating value than blown-in materials, but is more expensive and still subject to shrinking.
For use only on closed, properly vented exterior wall cavities. It should be sealed from exposure to the interior with vapor- and fume-resistant paints.
Also suited for sealing cracks around windows, doors and constructions seams.
Best for professional installation.
Can be used on the interior or exterior of the house, or on basement walls. Usually comes in board form in a variety of sizes ranging from 8” squares to 4’ x 12’ sheets.
Some types are made of fiberboard and are popular because of their durability and low cost. Fiberboard repels water, while the asphalt coating eliminates the need for building paper.
Another type is made of extruded polystyrene. It is very resistant to moisture and is most highly recommended for below-ground use.
Molded polystyrene board is another type that dissipates water well.
Another type is polyisocyanurate sheathing that is available with aluminum foil or glass fiber mat facers. This type has the highest R-value per inch of thickness of all insulation products.
Batt and roll insulation encapsulated for easier handling. Encapsulation enables the insulation to breathe and prevents condensation build-up.
Easier to handle by reducing dust and other irritants associated with insulation installation.
The non-woven type tends to stay in place better than plastic-wrap insulation. This product must meet all building code requirements for flame spread resistance, as it is flammable.
Sold in either pre-cut or perforated into shorter lengths. Use is similar to roll insulation, but best for use where there are many cross beams or other obstructions.
Available in R-values of R-11, R-13, R-15, R-19, R-21, R-22, R-30 and R-38. Thicknesses range from 3-1/2” to 12”.
Batts installed in wall should not be compressed to fit. Also, do not stuff behind wires. Rather, cut to fit around them.
Comes in continuous rolls that vary in width and thickness. Usually installed between open ceiling joists and wall studs.
Has a vapor barrier that should be installed with the vapor barrier toward the interior or heated area. Mend torn vapor barriers with tape.
Available in R-values of R-11, R-13, R-19 and R-25. Thicknesses range from 3-1/2” to 8”.
Comes compacted in bags and is poured or blown into walls and between joists of the attic floor. Good for retrofitting insulation into previously uninsulated homes.
Each bag is labeled according to federal specifications for both mineral wool and cellulose. Left column lists the R-value, second column tells how many bags are needed to cover 1,000 square feet of attic floor area, the third column gives the minimum thickness after completing the job.
Some manufacturers have two columns on thickness for loose-fill and cellulose insulation. The second of these is labeled “settled density”. This is important since cellulose settles quickly.
Types include fiberglass rock wool and cellulose. Cellulose is made from waste paper that has been treated to be fire retardant. It is also less likely to cause skin irritation.
Hinged panels allow overhead garage doors to roll up and down with ball-bearing rollers and a rope pulley on a steel track. Some panels have a polystyrene and/or air space between panels to insulate and deaden sound.
Some doors feature steel frame construction and a wood-grain raised-panel design, while others combine hardboard panels with a wood frame.
Comes with extension springs to help the door lift and balance, as well as safety containment cables to guard against injury.
Vinyl or aluminum bottom weatherseal counteracts uneven garage floors and protects against weather intrusion.
Pocket doors are ideal for wardrobes, dining rooms, bedrooms or anywhere space is at a premium. It frees up floor space by allowing the door to recess into the wall. The pocket door kit includes all the pieces needed to convert a regular doorframe into one that will accept a pocket door.
The door is sold separately, and is typically either a solid wood or hollow frame door that is slightly smaller than the size of the frame where it is being installed.
Kit includes tracks, rollers, steel/wood wall studs and miscellaneous hardware.
Provides extra security to the exterior door and protects against weather and stops drafts through door openings. Made of solid wood or has a wood or foam hollow core inside an exterior skin of metal, aluminum or vinyl.
Glass should be tempered to safety glass, while fiberglass screens offer durability and do not rust.

Comes in a variety of styles including sidelights, transoms and glass.
Typically galvanized steel facing with polystyrene, polyurethane, wood or particleboard cores. Offers more insulation, durability, fire-resistance and security than wood doors.
The steel exterior provides structural strength and eliminates cracking and warping.
Usually used as exterior doors.
Made of a tempered hardboard, wood or particleboard with or without a veneer, and from several kinds of solid wood. Ash, birch, mahogany, hemlock and pine are commonly used for solid doors.
Comes in standard widths for front and rear entrances. Narrower widths are sometimes used between house and garage and/or breezeway.
More fire resistant than hollow-core doors. Particleboard is more fire-resistant than natural wood and it resists warping because of its higher density.
Available pre-hung, which means the door is hinged in a framework that includes the header and side jambs of the door and the casing trim. The door may also be predrilled for the lockset.
Has wooden or cardboard ribs inside for stability. Primarily used as interior doors, as they will warp or disintegrate from weather.
Size is usually 1-3/8” to 1-3/4” thick, and usually 30”, 32″ or 36” wide.
Common height is 80”.
Also called lap cement roof adhesive. Designed to form a water-resistant and waterproof bond with most coated roll roofing products.
A trowel-grade, general-use sealing compound. Makes flashings, seams or patches in roofs and gutters water-repellent.
Used with roof cement to add strength and flexibility to surface repairs. Used with cold-applied roof coatings, meaning they can be applied direct from the container with little to no heating required for application.
Also called building paper. Installed under shingles.
Composed of a tough, fibrous base saturated with asphalt.
L-shaped weather-resistant metal. Installed at exposed roof edges (eaves) to help shed water and to protect the roof’s wood parts.
Strips of sheet metal or roofing material. Used to make waterproof joints on a roof.
Some flashing may be called a “boot”. This kind is specially made to fit around a vent pipe. They are often made of plastic. It fits snugly over the pipe and then slides under the shingles for a waterproof joint.
Seals with flashing sealant, usually sold in a tube and applied with a caulk gun.
Typically made of cedar, although composite wood shingles are available. Flat shape and a smooth texture.
Usually 1/2” thick.
Wood shakes are similar, but have a rougher texture. They are usually 1/2” or 3/4” thick.
More difficult to install than asphalt shingles.

Less expensive than shingles. Used on lower-slope roofs or as a supplement to shingles.
Comes with either a smooth or mineral-covered surface on a heavy felt base that has been saturated with asphalt and then coated on both sides with more asphalt.
Easy to install.
A typical roll roofing, known as 90-lb. granule-coated, will cover 100 square feet.
A 45-lb. smooth roofing, without granules, will also cover 100 square feet.
A properly applied roll roofing should last from 10 to 20 years.
Also known as a laminated asphalt shingle, or architectural shingle. An inorganic shingle.
Characterized by a more rugged texture than a standard three-tab shingle.
Weighs and costs more than standard shingles.
Made of two or more layers that are laminated to create the three-dimensional look, giving it the appearance closer to wood or slate roofing.
Has a base mat of glass fibers covered with ceramic-coated mineral granules. Some types may use a polyester or fiberglass blend for the base mat.
An inorganic shingle.
Features a better fire rating and often has a longer warranty than other types of shingles.
Does not absorb water and resists cracking.
Most come with seal-down strips. These are most effective when applied in warm weather, which allows the asphalt in the strip to soften and adhere to the next shingle.
An inorganic-based shingle usually has a Class A fire resistance rating from the Underwriters Laboratories (UL). UL also tests for shingle performance in high winds. To qualify for the wind-resistance label, shingles must withstand test winds of at least 60 mph for two hours without a single tab lifting.
Made of extruded aluminum and vinyl. Attached to the bottom of a door to help form a seal between the door and the threshold.
Used primarily in conjunction with a smooth top aluminum threshold to form a proper seal.
More durable and provides a better weather seal than a door sweep.
A non-self supporting type of ladder with two similar sections that are linked with internal guides on the bottom of base section and external guides on the top.
Sections are pulled apart to increase length.
Used for working in high areas and primarily for exterior applications.
Available in heights ranging from 16’ to 40’.
Smaller extension ladders are extended manually and secured with gravity spring lock brackets
that rest on the selected rung.
Larger extension ladders are extended by means of a rope and pulley running down the side of the ladder and secured with a cleat.
Generally available in all aluminum and fiberglass with aluminum rungs.
Rungs can be round or flat and are usually serrated for enhanced slip resistance.
Ladder shoes pivot to allow full contact with ground. Shoes can also be turned up to penetrate soft ground for extra stability.
Quality classifications include consumer (household), commercial (mechanic) and industrial grades.
Composed of thin OSB or plywood web that is bonded to the top and bottom flanges of lumber or LVL. Typically 9-1/4” to 30” deep and up to 60’ long.
Used as a structural component in roof and floor systems.
Some come with pre-drilled knockouts for easier plumbing and electrical installation.
Known as OSB. A structural-use panel used for roof sheathing, subfloors, underlayment, single-layer floors, exterior siding and wall sheathing.
Composed of elongated, thin strands of wood that are bonded with resin under intense heat and pressure.
A uniform panel free of knotholes that holds nails and screws securely.
Available in 4’ x 8’ panels in thicknesses of 3/8”, 7/16”, 15/32”, 19/32” and 23/32”.
Three grades are available: sheathing, single floor and siding.
Also known as wood fiber substrate. Made from wood chips that are mechanically reduced to wood fibers and then bonded together into panels through heat and pressure.
Panels are thin, grainless, dense, uniformly textured, strong and bone-dry.
Used as an exterior siding, interior paneling, as a garage door panel, perforated boards, for furniture, toys, cabinets, floor underlayment and many other items.
Can be sawed, shaped, routed and drilled and will accept paint and varnish.
Not recommended for use in areas with high temperature or humidity because warping can occur.
A hard, dense composition board made of very small particles of wood bonded together with resin under intense heat and pressure. Comes in various thicknesses from 3/8” to 3/4” and in panels 4’ x 8’; 10’ and 12’lengths are also available.
Often used in non-structural applications such as interior construction in closets and as an underlayment because it does not warp.
Should be cut with a carbide blade.
May swell if it gets wet.
Used to conceal joints when plywood panels or boards meet. Many plywood panels are v-grooved and hide the joint. If they’re not, use this trim.
Also called a laundry sink. Provides an extra deep, multi-purpose single bowl for pre-washing laundry or washing out items like paint brushes not suitable or other more expensive sinks.
Sturdy, durable and often made of fiberglass.
Offers the advantage of storage space under and next to the sink. The mounting for vanity sinks can be self-rimming, flush-mounted, undermounted or integral. Integral sink basins are typically made of solid surfacing or cultured stone, and any damage to the sink will mean replacing the entire unit.
In addition to cultured stone and solid surfacing, bath sinks are made of enameled steel, vitreous china, glass, cast iron and stainless steel. Vitreous china is the most common material, since it provides a high-gloss finish and is durable and sanitary.
For bath vanities, 34″-36″ is a more comfortable height for adults than the typical height of 30″-32″.
The bowl rests on a pedestal and does not have storage space underneath. The most common type of pedestal is made of vitreous china, but manufacturers offer other high-end types as well.
More difficult to install than countertop vanities.
Uses a high-speed rotating table powered by a sealed motor, it flings kitchen waste against a stationary shredder, cutter or grinder. This action, together with a full flow of cold running water that must be used while the disposal is operating, reduces the garbage to fine particles and flushes them down the drain to the sewage system.
Fits standard 3-1/2″ to 4″ sink drain openings and are installed under the sink drain.
Cold water congeals grease and prevents it from coating the drain line. Hard particles, such as bone and eggshell, actually scour the drain line as they whirl down and help keep it clean.
One type is the Continuous-Feed disposals. Garbage can be fed while the machine is in operation. These disposals are controlled by a wall switch and operated with a continuous flow of cold water.
A flexible splashguard at the disposal opening stops backsplash and helps to catch non-food items that may accidentally fall into the opening.
Batch-Feed disposals grind or pulverize food waste one load at a time. The hopper is filled and cold water added. When the cover is put in place, the unit begins operating. Some models have a magnetic switch control in the cover; others require a locking turn of the cover to activate the unit. No other switch is necessary. The safer design of batch-feed disposals makes them more attractive to homeowners with children.
A sealed motor requiring an electrical hook-up powers most garbage disposals.
The typical disposal has an overload switch that shuts off the motor if something is jammed.
Disposals will grind most garbage–from the sink and the dishwasher–but they are not intended for glass, crockery, leather, metal, newspaper, paper cartons, rubber or plastic.
The standard Drop-In tub installs within a tile or solid-surface surround within three walls of the bathroom, while the old-fashioned Clawfoot tubs are freestanding. Standard size for tubs is 60″ wide, 30″ deep and 14″ high.
Whirlpool and deep tubs are designed for soaking and relaxation. These tubs can be separate or incorporate a shower combination.
Cast iron tubs are the most durable and do not stain or scratch easily.
Acrylic is a better insulating material so the water takes longer to cool, and its light weight and flexibility makes it a better choice for larger tubs.
Fiberglass tubs are easy to install, but are more apt to fade and scratch.
Tub and shower combinations are typically made of reinforced fiberglass with a polyester finish.
Attaches to drywall, plaster or most any solid surface. Comes in three or more pieces that snap or caulk together for a leak-free fit.
Inexpensive alternative to tile and good solution for keeping bathroom walls around the shower easy to clean.
Don’t forget the caulk!
Some units come in one piece, mainly for new construction or major remodels. Some units come in multiple pieces that snap or caulk together to be a leak free.
Easy to clean and some manufacturers claim they will not chip, crack or peel.
Don’t forget caulk.
Often sold in a style that matches other bathroom accessories, and some manufacturers will match them to light fixtures. Mount on the wall or shower door.
Fancier models are stand alone and heated.
Sold in a variety of finishes.
Often sold in a style that matches other bathroom accessories such as towel bars. Comes either stand-alone or wall-mounted.
Vents exhaust from the attic and extends the life of the roof. Typical widths are 9” and 12”.
Helps keep the attic cool and reduces air conditioning costs.
Helps prevent ice dams.
Shingle-over ridge vents incorporate shingles that match the roof and are nailed over the vent.
Pre-drilled holes make installation easy.
Most types feature baffles because ridge vents without baffles can allow wind and moisture to enter the attic.
An air intake on the soffit or eave. Helps balance the flow of air into the attic from the ridge vent.
Usually made of either aluminum or PVC.
Reversible soffit vents can be flush or recessed mounted.
Designed to complement most brands of vinyl siding. Installs before or after the siding.
Requires little maintenance.
Features open louvered joints and built-in screens to keep out bugs and birds.
Comes in a variety of shapes, including octagon, pentagon, round, square, half-round or rectangular.
Turbine vents that consist of a turbine mounted on a sheet metal cylinder. Installed like roof line vents along the face of the roof.
When the wind blows, it spins the turbine, which in turn draws air up out of the attic.
Their effectiveness depends on whether the wind is blowing or not.
Used to ventilate basements and crawl spaces. May be constructed of steel, aluminum or plastic.
Used with brick, block or frame construction.
Provides an exhaust for the dryer. Most models feature flaps or louvers that remain closed when not in use.
Available in a kit that includes the vent, ductwork and dryer attachment.
Offers a waterproof surface for installing outlets, lighting and plumbing fixtures with new siding. Used with wood, aluminum, vinyl, stucco, brick or shake siding.
is available in a variety of colors, textures and profiles. Vinyl siding Benefits include easy installation and low maintenance. Color is solid throughout, so scratches don’t show. Available in widths up to 12” in lap.
Aluminum siding is used less frequently than vinyl siding. Has a baked-on enamel factory finish that fades over time and needs to be repainted. Can be installed over any structurally sound surface. Must be grounded with a No. 8 or larger wire to the cold-water service or the electrical service ground.
Wood siding typically comes in redwood and cedar. Wood is a natural insulator and adds to the R-value of the wall. Not as popular as other types of siding as it is high maintenance. May be stained or painted.
Fiber cement siding looks, feels and installs similar to wood. Created by mixing Portland cement, sand, clay and wood fiber and forming it into siding panels with various textures, including wood grain, smooth or stucco texture. Usually comes primed and ready to paint. Has a Class 1 (A) fire rating and resists rot and wood-boring insects.
Outside corner posts provide a more finished appearance at the outside corner of adjoined walls. Inside corner posts provide a more finished appearance at the inside corner of adjoined walls.
Installed for safety around tubs to help prevent falls. Also used as a handrail to help anyone who may have trouble sitting down or standing up.
Never use a towel rod in place of a grab bar.
Never install diagonally, as a person’s hand might slide if footing isn’t secure.

It opens from the top and bottom.
A popular variation is the single-hung window that has a sash that slides vertically. The second sash remains stationary.
Has a single sash hinged at one side to swing open by means of a crank or lever. Tends to be more weathertight than double-hung, single-hung or sliding windows.
Utilizes a cam-type lock to draw the sash tightly against the frame when closed.
Has a single sash hinged at the top. Opens at the bottom with a hand-turned crank.
More durable than casement windows.
One type is the basement utility window that is made with a block frame for easy installation in a masonry wall.
Another type is the ranch unit, which has the window framed in a brick mold for installation in garages, cottages and utility buildings.
Another type is the hopper window, where the window is hinged at the bottom.
A bay window is made of three windows: one large unit in the middle and two flanking windows that are usually placed at 30- to 45-degree angles. A bow window is made of four or more windows that, all together, form a shape that curves outward. It looks like a bay window, but is free of sharp angles.
A fixed window. Has no moving parts or sashes and does not open.
Sometimes used with another window type, such as an awning window.
Usually a fixed window available in various shapes, such as an oval, arch, ellipse, octagon or circle.
Slides horizontally to open. Durable, since the sash is fully supported in the frame.
The nail-on frame style uses nailing flanges and is used mainly in new construction.
The block frame style is used either as a replacement window or in block construction.
Used to maintain outdoor asphalt surfaces. The ultraviolet rays of the sun damage the asphalt binder used as the paving material. The sealer protects asphalt against oil, tar and gasoline and keeps water from settling in pores.
Apply at 70°F or higher and require 24 to 48 hours to dry before use.
The coal tar type of sealer needs to be resurfaced yearly and may contain hazardous chemicals.
The acrylic sealer type is non-toxic and environmentally friendly.
Used to plug running leaks in masonry surfaces. Stops water leaks under pressure and can be used under water.
Used inside or outside, above or below the ground.
Usually constructed of nylon. Polyester, wool, acrylic and polypropylene are also used. Styles include level loop pile (Berber), multi-level loop pile, cut and loop pile, cut pile and sisal.
Quality of carpet depends on the density of construction (the denser the better) and the twist, or how many fibers have been intertwined to make the yarn (the tighter the twist, the better the carpet).
Use with carpet padding to extend the life of the carpet.
Installation products will include tack strips, a sharp razor-type knife, a chalk line and a straight edge.
Usually comes in 12’ widths.

Generally available in large, 12’ rolls in varying lengths, or in square tiles. Available in a variety of patterns and colors.
Most floors have a no-wax surface, although most manufacturers recommend specially formulated floor finish to enhance or restore shine and provide added protection.
Quality depends on the thickness of the material. In general, urethane floors last longer than vinyl.
Installed by gluing to the subfloor with an adhesive made for the material.
The square tile type often has an adhesive backing that makes for easier installation.
Available in planks or parquet tiles. Some types install with nails, others with glue.
Popular types of wood are oak, maple, beech, birch and pecan.
Has tongue and groove joints for a tight installation.
A popular alternative to solid hardwood flooring. The surface veneer is made of hardwood such as maple or oak, while tongue-and-groove strips underneath are constructed of plywood.
Easy to install because it can be installed without a subfloor and requires no sanding or finishing.
Usually installed by gluing to the subfloor, although some types snap together and do not require glue.
The size of the veneer will determine the floor’s durability. High-quality engineered floors feature surface veneer of 5/32” to 1/8”.
Made of natural marble. Slick and easily scratched, although scratches can be buffed out.
Tiles should be sealed after installation.
Types include travertine (for exterior use), while (translucent) and green (usually installed with water-free epoxy mortars.
Softwood paneling comes in either knotty grades (2 & Better Common and 3 Common) or clear grades (Superior, Prime, Select, C & Better Select or D Select). Hardboard panelings have vinyl, printed or paper surfaces that make them look like genuine wood. Woodgrain finishes are the most popular, but other varieties are available in solid colors, marbleized patterns and novelty designs.
Another type is plywood wall paneling. On the back of these panels, a stamp will indicate information such as glue type, fire resistance, wood species used and structural description.
Comes in 4’ x 8’ sheets in thicknesses from 1/8” to 5/32”.
Have either smooth or V-grooved edges.
Perforated paneling is a hardboard that comes in 4’ x 8’ sheets in thicknesses of 1/8” or 1/4”. Thicker panels will support more weight.

Most common species are Douglas fir and Hem-fir.
Can be classified as High Quality Appearance, General Purpose Board or Radius-Edged Patio Decking Grade.
The Western Wood Products Association (WWPA) has a rigorous inspection and quality control process. Lumber with the WWPA logo indicates the lumber has passed that quality control process.
Lumber with only the “WWPA Rules” stamp indicates the lumber has been graded according to the WWPA rules, but not been inspected by WWPA.
Provides a rigid installation for mounting an elbow to a wall. Usually used for installing a shower arm or washer hose valve.
Some variations include fittings that can transition from plastic to brass or copper.
Also known as a wing elbow.
Soffit panels enclose the underside of an eave. Fascia panels enclose the front of an eave.
Used to trim out the ends of siding panels where they meet a door or window. Also used to cover cut edges of panels around windows and under the eaves.
Sometimes called combination windows because they combine the functions of storm and screen windows. Typically made of aluminum
Easy to install and usually attached directly to the exterior casing surrounding the window.
The single-track type consists of a piece of glass in a lightweight sash, fixed permanently in a nail-on frame.
The dual-track style has a glazed sash and screen. The glazed sash is in the top half of the outer track and the screen is in the lower half. Another glazed sash in the inside track covers the screen and can be raised to uncover the screen for ventilation.
The triple-track storm window has two glazed sash and a screen panel, all in a separate track. This is best for second floor windows.
A window installed on a sloping roof. Also called a roof window. Can be stationary or vented.
Sizes range from 18” to 60” wide to 18” to 60” long. Usually, there should be only one square foot of skylight for every 20 square feet of floor space.
Opening the window can be controlled by a manual crank,sometimes reached with a long pole, or by a remote electronic operation.
A tubular skylight is one type designed for rooms where a larger, standard skylight may not be practical. Easy to install, it features a one-piece flashing system to eliminate the possibility of leaks.
A self-flashing or curb-mounted roof window works best with asphalt or fiberglass shingles.
Consists of a core of gypsum plaster covered with two sheets of heavy paper. Panels are 4’ wide and range in length from 6’ to 16’.
Boards 1/4” thick are normally used for recovering old walls and ceilings.
Boards 3/8” thick are used in two-ply construction.
Boards 1/2” and 5/8” are used in single-ply new work. 5/6” boards provide better fire resistance and sound control.
Benefits include low cost and ease of installation. The plain-papered face provides an excellent surface for paint or wallpaper.
The edges are typically made with a slight taper, which allows for a filled and tapered joint.
