Homeowners Synergy Spray Foam & Air Conditioning wonder how much insulation is enough. In fact, the recommended amount of insulation varies greatly depending on where your house is located and the climate zone it’s in. The more insulation you have, the less energy your home will use. Insulation is measured using R-value, and the higher the R-value, the more efficient the insulation.

The R-value required for wall, crawl space and attic insulation is based on your climate zone. Use this map to find out what your zone is and these tables to see what R-value is recommended for your area.

Installing Insulation in Old Attics

Whether you’re in the process of building new construction or insulating an existing house, this calculator will help you determine how much insulation to install. Simply enter your project details, including the square footage of walls and ceilings you need to insulate and click “calculate”.

Note: This calculator assumes that you’re using insulation materials such as rolls or blanket batts that fit between floor joists, wall studs and attic rafters. If you’re working with a difficult to reach space or an awkward structure, you may want to consider using blown-in insulation.

It’s always a good idea to work with a professional insulation contractor when insulating your home. Besides ensuring that the R-value you select meets your home’s insulation needs, they will be able to provide you with an accurate cost estimate for your project and apply for our Home Insulation Rebate on your behalf.
