Attic Insulation for Net-Zero Homes

One of the most cost effective improvements that can be made to any home is insulating the attic. This can reduce energy costs by preventing unwanted air flow from the attic into the living space below. An attic should be insulated to R-49 to keep conditioned air inside the home and unconditioned air out.

CEC Spray Foam the obvious benefits of lowering heating and cooling bills, more insulation in the attic can also increase the energy efficiency of a house. It is a great place to install insulation because it can be blown in rather easily and it is less expensive than installing insulation in the walls or even the foundation of the house.

Attic Insulation for Net-Zero Homes: Where Efficiency Begins

In new construction, a high R-value in the attic can be achieved by sealing air leaks and then blowing in fiberglass batts or cellulose insulation. Closed-cell spray foam is another option, but it can be more expensive than cellulose or fiberglass. It is impermeable to moisture, which is useful in unvented attics and crawl spaces, and improves airtightness. It can be made from natural materials such as wood fibers, mineral wool, or cellulose, or from synthetic polyurethanes and polyethylenes that do not use hydrofluorocarbons (HFCs), which have severe negative impacts on global warming and the environment.

It is best to use professional insulation installers for proper installation and maximum performance. They have the expertise to help you select the best insulation material for your climate zone, project goals, and budget, as well as provide a professional installation with minimal disruption.
