Expanding Foam Insulation

Although the emphasis on saving home heating and cooling energy has been on attic insulation, exterior walls have a similar surface area that transmits energy.
Homes built prior to 1960 had no insulation or at best R-5. Between 1960 and 1980’s average R values increased to about R-11.
Insulating wall cavities that were empty or under-insulated will [...]

Insulation in the roof and walls is clearly beneficial for its ability to reduce heating and cooling losses and costs. The savings achieved by reducing heat transfer by conduction justifies the cost of adequate insulation.
But don’t forget that convection is another source of heat transfer when air moves between two spaces. Minimizing or controlling losses [...]

Fire resistant foam insulation contains fire retardant, and some are specifically formulated for fire resistant use.  If you need a fire resistant foam for insulation, be sure to choose one specifically marketed as such.  These products possess a higher degree of fire resistance than standard foam insulation.
Fire Resistant Applications include :
- fire resistant installation of [...]
