There are several factors to consider when selecting the right insulation for your particular problem. One of the most important factors should be the R-value as you want an insulation that exhibits maximum insulating capabilities. Insulation should also inhibit characteristics such as resistance to mold and insects, especially if you’re insulation is geared toward preventing convection.
Since insulating a space is aimed at energy conservation, the right insulating material should be the one that best translates to energy savings. Spray polyurethane foam is usually the recommended insulation type for attics due to their susceptibility to air leaks. The foam has special capabilities to completely cover a hole and crevice in the attic, preventing any form of air entry.
Most of our insulation products at Spray Foam GTA are designed to block the entry and loss of heat in a building. Once a dent in the wall is completely covered, you can be assured of heat loss prevention.
