Q: What are your materials?
A: We use a specially formulated closed cell polyurethane foam with a rated R value of 7.7. The material is an air barrier and absorbs virtually no water (its used for flotation in boats among other things).
Q: Are your materials new?
A: Our materials have been used to insulate water heaters, refrigerators, HVAC equipment and other manufactured products for well over 60 years. We have figured out how to adapt these proven products for insulating buildings.
Q: Are the materials safe?
A: This material does not spray hazardous particles into the air like spray foam. We have had 3 rounds of air quality testing completed. Published test results will be available shortly. In all 3 rounds of testing, hazardous particulates have been virtually non-existent both during and after application.
Q: What is your process?
A: Its a simple 3 step process. We first mask off the room, prep the walls and drill holes. Then we inject a few cavities to develop an optimized fill rate for the building. And finally we inject the entire building.
Q: What dispense equipment do you use?
A: For most walls, we use a proprietary needle dispenser. If the wall has obstructions, we use a proprietary tube dispenser to get behind the obstructions.
Q: What other equipment is needed?
A: Standard low pressure proportioners can be used for most buildings. For large buildings, Building Envelope Materials has developed a proprietary mobile “talking” proportioner. Besides communicating with the operator, the talking dispenser can validate the quality of the materials in the wall. More information on this system will be available shortly
Q: Who does the insulation?
A: For large buildings in the Northeast US, Building Envelope Materials will usually do the insulation. For all other buildings, trained and certified contractors do the insulation. The system requires special equipment and is not available to un-certified installers.
