Frequently Asked Questions
	Q: How does CORBOND® work?
	A: The purpose of buildings for people is to isolate them comfortably from a hostile exterior climate. The purpose of insulation is to develop this climate isolation beyond minimum shelter to allow complete modern interior climate control. To achieve this climate isolation successfully, requires full isolation between interior and exterior air and moisture. The two climates must not mix in the insulated building cavity. The system must also be reversible so the building may be both heated and cooled efficiently. CORBOND achieves the climate isolation necessary by its nature as a solid cellular plastic. - fully adhered in the thin space of the building cavity. Exterior and interior climates cannot mix so no compromise of climate isolation can occur due to the exterior climate conditions, however severe.
	Q: Does CORBOND® need venting like conventional fibrous insulation?
	A: NO. CORBOND® does not need venting. Venting was designed to carry moisture out of fibrous insulation so it can maintain its thermal efficiency and minimize the damaging effects of condensation on hidden building surfaces. With CORBOND®, no air can enter into or through the product as it is a solid cellular foam. Since no air or moisture can get in or around CORBOND®, it need not be vented off.
	Q: How does CORBOND® control moisture movement and condensation?
	A: Most damaging moisture within a building cavity is the result of warm moist inside air being exchanged with the cold dry air inside an insulation cavity. As the moisture in the warm air contacts a cold surface, it condenses, forming dew and/or frost within the insulation. Because CORBOND® does not allow the movement or exchange of air within the cavity, this moisture movement and condensation does not occur. CORBOND® is ideal for use in climates where buildings are both heated and air-conditioned (mixed climates) because the situation is reversed in summer with the potential for moisture to form on the back of the interior vapor retarder if fiber insulation is used.
	Q: Does CORBOND® contain formaldehyde?
	A: NO. Spray-in-place polyurethane insulation, and particularly CORBOND® does not contain formaldehyde resins. CORBOND® is made of resins similar to popular polyurethane varnishes for wood.
	Q: At what point during construction is CORBOND® sprayed into place?
	A: CORBOND® is applied before the sheet rock is put in place but after plumbers and electricians have completed rough-in work. The spray-in-place product creates a bedding around the pipes and closes all penetrations in and through the exterior walls of the structure, which completes a nearly monolithic insulating blanket. CORBOND® can be installed quickly, even in fairly extreme weather conditions. An average house of 1300 square feet may take a trained crew 5 to 6 hours to complete.
	Q: Is CORBOND® environmentally friendly?
	A: YES. CORBOND® II product uses a new generation of environmentally friendly ingredients CORBOND® now contains no CFC's. Also, its superior insulating capabilities dramatically reduce heating and cooling demands, reducing harmful emissions from power plants and home heating units.
	Q: What happens if owners want to add an electrical outlet once CORBOND® is installed?
	A: If an outlet must be added, CORBOND® drills more easily than wood. There is also, typically, a small space left between the wall board and the CORBOND® so a wire can slide through.
	Q: Can you drill holes in existing walls and fill them with CORBOND®?
	A: NO. When CORBOND® expands, it is very strong. As a result, it may distort a closed wall cavity and then set up hard. CORBOND® is always sprayed into an open cavity. This also allows for better job quality control because the technician can see what is being insulated.
	Q: How long does CORBOND® last?
	A: INDEFINITELY. As an insert, long lasting polymer plastic, a house wall or commercial structure is the perfect place for CORBOND® to do its job for a long time.
