Additional information

R-value

The R-value measures how well insulation can prevent heat from moving through it. It is influenced by factors such as insulation material, thickness, and density. The higher the R-value, the more effective the insulation is at reducing heat flow. Consulting with insulation professionals can help determine the appropriate R-value for optimal thermal performance and energy efficiency.

Attic insulation is defined as insulation that is installed in the attic crawl space, typically on a horizontal surface. Roof insulation is defined as insulation that is installed in direct contact with the building’s roof, typically a flat or slightly pitched surface. PSE insulation rebate only applies to attic insulation.
