Builders and building scientists know that the greatest enemy of building efficiency is air infiltration and movement of air into insulation. The enemy of building longevity is hidden moisture condensation causing mildew and decay, not to mention the threat to health and comfort caused by these agents. PROFOAM foam insulation is the solution to these concerns of insulation contractors, builders, designers and building owners.
How does Spray Foam work?
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, moisture and temperature. 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. SPRAY FOAM achieves the climate isolation necessary by its nature as a solid closed 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.
Does PROFOAM need venting like conventional fibrous insulation?
No. PRO FOAM does not need venting. Venting was designed to carry moisture out of fibrous insulation so it can maintain its thermal efficiently and minimize the damaging effects of condensated water in hidden building cavities. With SPRAY FOAM no air can enter into or through the product as it is a solid cellular plastic. Since no air or moisture can get in or around SPRAY FOAM it need not be vented off.
How does SPRAY FOAM control moisture movement and condensation?
Most damaging moisture within a building envelope cavity is the result of warm moist air being exchanged with the cold dry air inside an insulation filled cavity. As the moisture in the warm air contacts a cold surface, it condenses, forming dew and/or frost within the insulation. Because SPRAY FOAM does not allow the movement or exchange of air within the cavity, this moisture movement and condensation does not occur. SPRAY FOAM is ideal for use in climates where buildings are both heated and air-conditioned (mixed climates) because the situation is reversed from winter to summer with the potential for moisture to form on the back of the interior vapor retarder if fiber insulation is used.
Does SPRAY FOAM contain any harmful substances?
No. SPRAY FOAM is made of resins similar to popular polyurethane varnishes for wood. SPRAY FOAM does not contain formaldehyde.
At what point of construction is SPRAY FOAM sprayed into place?
SPRAY FOAM 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. SPRAY FOAM can be installed quickly even in fairly extreme weather conditions. An average house of 1800 square feet may take a trained crew only 6 to 8 hours to complete.
Is PROFOAM environmentally friendly?
Yes! SPRAY FOAM product uses a new generation of environmentally friendly ingredients. SPRAY FOAM contains no CFCs. Also, its superior insulating capabilities dramatically reduce heating and cooling demands, reducing harmful emissions from power plants and home heaing.
What happens if we want to add an electrical outlet once SPRAY FOAM is installed?
If an outlet must be added, SPRAY FOAM drills more easily than wood. There is also typically small space left between the wall board and SPRAY FOAM so a wire can slide through.
Can you drill holes in existing walls and fill them with SPRAY FOAM?
No. When SPRAY FOAM expands it is very strong. As a result it may distort a closed wall cavity and then set up hard. SPRAY FOAM is always sprayed into an open cavity. This also allows for better job quality control because the technician can see what is being insulated.
How long does SPRAY FOAM last?
Indefinitely. As an inert, long-lasting polymer plastic, a house wall or commercial structure is the perfect place for SPRAY FOAM to do its job for a very long time.
