General Information About Foam Insulation
Residential construction methods have been generally consistent for decades. As new technology develops, the construction professionals gain experience and confidence in incorporating new products into the complicated composite we know as a “home”.
Homes have historically been built to intentionally allow structures to “breathe” for fear of trapping moisture. Uncontrolled moisture presents a clear concern for the longevity of most building materials. The “breathability” alleviates the concern for reasonable amounts of unmanaged moisture, but unfortunately does not control the inflow of airborne pollutantsk, allergens and the loss of conditioned air. This lack of control compromises the indoor air quality as well as significantly increases consumer costs through energy loss.
Spray foam technology by AeroFoam eliminates the aforementioned issues by raising the standards of functionality and design for both residential and commercial construction. Spray polyurethane foam has been commercially available for over half a century and is now being accepted as a mainstream solution in retrofit construction for both residential and commercial buildings.
The predominant heat transfer mechanism for spray foam by AeroFoam is conduction. However, because the polymer matrix forming the cells is a poor conductor of heat, spray polyurethane foam has a very high R-Value and effectively blocks heat transfer by conduction.Spray foam eliminates air movement within the insulation material eliminating convection as a heat transfer mechanism within the insulation mass.
Heat transfer by radiation is effectively blocked by spray foam because of the cell structure. Heat can transfer by radiation across each cell. However, because the cells are at basically the same temperature, heat transfer by radiation is virtually non-existent. Additionally, the building interior walls insulated with spray foam by AeroFoam tend to be nearly the same temperature as the room; therefore radiant heat variances to an occupant is minimal and leads to greater indoor comfort.
In order to design and build safe, healthy, durable, comfortable and economical buildings, airflow must be controlled. Uncontrolled airflow carries moisture that impacts a materials long-term performance (serviceability), structural integrity (durability), indoor air quality (distribution of pollutants and location of microbial reservoirs) and thermal energy performance. One of the key strategies in the control of airflow is the use of air barriers.
Air barriers are intended to resist the air pressure variations that act on them. AeroFoam's Spray foam systems can serve as a successful air barrier, either externally applied over structural elements (closed-cell spray foam) or internally applied (closed-cell and/or open-cell spray foam), within cavity systems at the proper thickness.
Air barrier systems keep outside air out of the building enclosure or inside air from escaping the building enclosure depending on climate or configuration; sometimes, air barrier systems do both. Air barriers can be located anywhere in the building envelope.
The benefits of AeroFoam's spray foam plus the expansion of the material in place will create a total seal. Spray foam by AeroFoam is one of the only insulation materials that will fill in corners, the cripples, the double studs, bottom plates and top plates etc.
The adhesion of spray foam insulation to most building materials creates a total seal to the building envelope. Stopping air intrusion is one of AeroFoam's spray polyurethane foam’s greatest assets.
Spray foam applied by AeroFoam stops moisture accumulation by reducing air infiltration and air intrusion. In addition, closed-cell polyurethane foam retards both heat transfer and water vapor transfer making it an ideal material for use with flow-through designed building assemblies.
