Insulation slows the transfer of heat between the inside and the outside, keeping a home warm in the winter and cool in the summer. Other benefits of insulation include maintaining an even temperature throughout the home, reducing unwanted outdoor noise, and reduced energy bills.

HAAS Consideration: Before insulating, air sealing should be completed on air leakage
pathways into walls and attics to maximize the efficiency of the insulation and to prevent
moisture from entering into the insulated area and damaging new insulation or creating
mould or wood rot.
