Insulation and Air Sealing
Spray Foam Insulation
Spray foam can be used as an insulating and air sealing product for wall and ceiling cavities. The insulation is sprayed into wall cavities and expands to fill all the nooks and crannies in a wall cavity. Excess foam is scraped off the studs to form a uniform wall cavity. Because it expands into tight areas, sprayed foam is ideal for insulating steel framing and around outlets. By acting as a wind and air barrier, it often eliminates the need for separate air-tightness detailing, which can increase energy efficiency and allow downsizing of the heating and cooling system equipment. Sprayed foam insulation does not shrink, sag, settle, or biodegrade.
Pour Fill Formula
Spray Foam's pour fill variation is an insulation and air barrier that injects the latest building technology into an older building to maximize energy efficiency while still preserving its original architectural details. Spray Foam Insulation fills the wall cavity completely, starting at the bottom and slowly expanding upwards to 60 times its initial volume. Since Spray Foam expands in the direction of least resistance, it will not expand outward and damage the wall.
Cellulose Insulation
Cellulose insulation is made primarily from recycled paper. About 75 percent of the material used to make cellulose insulation is post-consumer waste paper. Cellulose insulation is blown into wall and ceiling cavities as well as onto attic surfaces, though to stick to attic ceilings it must be held in by netting or sprayed on wet with an acrylic binder to prevent settling. Like all sprayed or blown insulations, it can be installed into wall cavities through a series of small holes in the wall, causing little disturbance during remodeling. It is not suitable for application below grade (below or at the perimeter of the foundation) or in other locations where it would be exposed to moisture.
Radiant Barrier Insulation
Installed in residential and commercial buildings to reduce Summer heat gain and Winter heat loss, a Radiant Barrier is a thin sheet of reflective material installed on one or two sides of the structure. The Radiant Barrier helps reduce the air temperature of the attic – or adjoining room – by preventing radiant heat from transferring in or out of the space.
Sealing Ducts
In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In a typical house, however, about 20 percent of the air that moves through the duct system is lost due to leaks and poorly sealed connections. The result is higher utility bills and difficulty keeping the house comfortable, no matter how the thermostat is set.
Because some ducts are concealed in walls and between floors, repairing them can be difficult. However, exposed ducts in attics, basements, crawlspaces, and garages can be repaired by sealing the leaks with duct sealant. In addition, insulating ducts that run through spaces that get hot in summer or cold in winter (like attics, garages, or crawlspaces) can save significant energy.
