Wall where all of the interior space, either between the framing or the solid portions of the masonry wall, is filled in with insulation material. This is done to lessen noise transmitted through the wall or heat loss.
Window manufactured with at least two panes of glass with air space between the panes, which helps to stop heat from transferring through the glass.
To provide an R-factor, which is a measurement of resistance to temperature transmission, of about 1.1.per inch of thickness concrete must have an expanded mica aggregate of 6 to 1, aggregate to cement.
Used to prevent galvanic corrosion on dissimilar metal flange joints, the kit consists of electrically non-conductive gasket, sleeves and washers. To isolate the shanks of the bolts from the inside diameter of the flange bolt holes, the sleeves are fitted over the bolts or studs that hold the flanges together. Washers are positioned under the nuts to isolate them from the flange. Then, the gasket is positioned between the flanges. Removal of any remnant of electrical conductivity prevents the lowest metal on the galvanic scaled from being corroded by the touching metal.
Panels of glass separated by air space.
Plastic compound or other synthetic material, non-electrically conductive varnish, used to coat and insulate copper wire.
Materials, such as fiberglass, rock wool, urethane foam, polystyrene, cellulose and vermiculite, which are used to slow heat loss. Insulation comes in different forms: blanket, batt, rigid, fill, reflective, made of glass wool, cotton or wood fibers. Organic materials must be pretreated to become insect, fire and decay resistant.
Pre-cut, flexible, insulation, which fits between framing members, coming in 4 and 6 inch thickness for 16 and 24 inch joist spacing and is made of glass wool, wood fibers or cotton.
Packed pre-cut or rolled insulation which usually comes in a thickness of 3 ½, 5 ½, or 7 ½ inches, and fits between 16 or 24-inch studs. Made of flexible materials such as glass wool, cotton, wood fiber, or rock wool which must be pretreated to become insect, fire and decay resistant.
Protective rim, along the edge of the batt type of insulation, which holds the insulation in place by being stapled to the studs or joists.
Examples of flexible insulation:
Batt Insulation - Pre-cut, flexible, insulation, which fits between framing members, coming in 4 and 6 inch thickness for 16 and 24 inch joist spacing and is made of glass wool, wood fibers or cotton.
Blanket Insulation - Packed pre-cut or rolled insulation which usually comes in a thickness of 3 ½, 5 ½, or 7 ½ inches, and fits between 16 or 24-inch studs. Made of flexible materials such as glass wool, cotton, wood fiber, or rock wool which must be pretreated to become insect, fire and decay resistant.
Effectiveness of insulation is determined by the number given to it. R-values measure thermal resistance, K-values measure the heat conductivity and U-values indicate the overall heat flow between air on the warm and cold sides of the insulated area.
Insulation with a heat reflective surface and backing if either sheet metal, aluminum foil, etc.
Nonflexible panels, used for both sound and thermal insulation, of materials such as Styrofoam and urethane foam or hard plastics such as polyvinyl chloride or alternately, cellular glass, corkboard, balsa wood, etc.
Since heat transfer through an insulator happens by conduction or radiation, thermal materials are used to lessen the flow of heat in or out of steam pipes, buildings, refrigeration units, etc. Different materials give better insulation for certain applications and are available in a variety of forms and materials such as foams of polyurethane or polystyrene; loose fill insulators are of diatomaceous silica, perlite, calcium silicate, plastic beads, charcoal granules, vermiculite or charcoal granules; rigid insulator are PVC, balsa wood, cellular glass, corkboard, urea, polyurethane or polyethylene. Fiberglass, sprays of macerated paper or insulating concrete, aluminum foil, etc. are other types of thermal insulation.
Materials that do not conduct electricity are used to control and direct the flow of electrical current in products use electricity. Electrical insulators range from Teflon to varnish coating and are chosen with the use conditions in mind.
Title to a property that can be insured against defects and disputes.
An interest in a person or property that would cause on a loss if that person or property were injured or ruined.
Policies that guarantee compensation for losses from a specific cause. Various forms of insurance cover against fire, flood, earthquake, liability, etc.
Temporary insurance arrangement used until a permanent policy can be issued.
