Ensuring your home is properly insulated can improve energy efficiency and make your home more comfortable. Insulation acts like a cozy coat that reduces heat loss during winter months and a protective layer that reduces heat gain during summer months.
Many older homes have less insulation than newer homes, but even newer homes can benefit from additional insulation. Although it’s not the least expensive efficiency improvement, adding insulation and air sealing your home can provide the biggest bang for your buck in energy savings and overall comfort.
The most common areas to insulate are attics, ceilings, crawlspaces or unconditioned basements, exterior and interior walls, floors, and ductwork located in unconditioned spaces.
The amount and effectiveness rating of insulation required for each area varies by climate, but many websites, such as the U.S. Department of Energy or Home Depot, provide easy-to-follow recommendations.
Visit the Department of Energy's insulation webpage to learn about recommended R-values for specific areas of the home based on climate zones. NAEC’s service area is in climate zone 4. Required R-values are as follows:
It’s important to understand how insulation effectiveness is measured. Insulation is rated in R-value, which measures the material’s resistance to conductive heat flow. The higher the R-value, the greater the insulating effectiveness. The R-value you’ll need depends on factors, such as climate, type of heating and cooling system and which area of the home you plan to insulate.
Insulation is offered in a wide range of materials from bulky fiberglass rolls to cellulose materials made from recycled paper products. If you’re considering installing additional insulation, talk to an expert who can offer guidance on the right materials for your budget, climate and comfort needs.
Investing in proper insulation for your home not only enhances comfort but also reduces energy consumption.
