Wrapped in Savings

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. While 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 walls, floors, and ductwork located in unconditioned spaces.

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 like climate, how much space there is and which area of the home you plan to insulate. Typically, we recommend insulating the attic space to a R-49, which is current code minimum, and both walls and crawlspaces to fill the cavity space between joists.

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.

Investing in proper insulation for your home not only enhances comfort but also reduces energy consumption. CEC offers energy efficiency programs to help some members make updates to the insulation in their homes.
