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 [...]

Expanding foam insulation is a method of applying a liquid resin that reacts with air to expand into its surroundings. The resin can be injected into small or large voids to fill the space with a solid foam. The resulting foam can seal gaps and cracks to prevent air from entering into your home. It [...]

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 [...]
