1. How does Closed-Cell 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 the minimum to allow complete modern interior climate control.
To achieve this climate isolation successfully requires isolation between interior and exterior air and moisture and the system must be reversible so the building may be both heated and cooled efficiently. By its solid cellular plastic, fully adhered in place nature, Closed-Cell Spray Foam achieves the climate isolation necessary 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.
2. Does Closed-Cell Spray Foam need venting like conventional fibrous insulations?
No. Closed-Cell Spray Foam does not need venting. Venting was designed to carry moisture out of fibrous insulation so it can maintain its thermal efficiency by trapping dry air. With Closed-Cell Spray Foam, 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 it, it need not be vented off.
3. How does Closed-Cell Spray Foam control moisture movement and condensation?
Most damaging moisture within a building envelope 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 air condenses, it forms dew and/or frost within the insulation. Because Closed-Cell Spray Foam does not allow the movement or exchange of air within the cavity, this moisture movement and condensation does not occur. Closed-Cell Spray Foam is ideal for use in climates where buildings are both heated and air conditioned because the situation is reversed in summer with moisture forming on the back of the interior vapor retarder.
4. Does Closed-Cell Spray Foam contain formaldehyde?
No. Spray-in-place polyurethane insulation, and particularly Closed-Cell Spray Foam does not contain formaldehyde resins. Closed-Cell Spray Foam is made of resins similar to popular polyurethane varnishes for wood.
5. At what point of construction is Closed-Cell Spray Foam sprayed into place?
Closed-Cell 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. Closed-Cell Spray Foam can be installed quickly even in extreme weather conditions. An average house of 1300 square feet may take a trained crew 5 to 6 hours to complete.
6. Is Closed-Cell Spray Foam environmentally friendly?
Yes! Closed-Cell Spray Foam product uses a new generation of environmentally friendly ingredients. Closed-Cell Spray Foam 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.
7. What happens if the owners want to add an electrical outlet once Closed-Cell Spray Foam is installed?
If an outlet must be added, Closed-Cell Spray Foam drills more easily than wood. There is also typically a small space left between the wall board and the Closed-Cell Spray Foam so a wire can slide through.
8. Can you drill holes in existing walls and fill them with Closed-Cell Spray Foam?
No. When Closed-Cell Spray Foam expands it is very strong. As a result it may distort a closed wall cavity and then set up hard. Closed-Cell 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
9. How long does Closed-Cell Spray Foam last?
Indefinitely. As an inert, long lasting polymer plastic, a house wall or commercial structure is the perfect place for Closed-Cell Spray Foam to do its job for a long time.
So now, your commitment to perfection can extend beyond your unique designs and developments and into a strong, comfortable, thermally efficient building with the help of Closed-Cell Spray Foam... the Performance Insulation.
