Next to attic insulation, wall insulation is the most critical. Wall insulation improves your home’s thermal envelope, reduces the amount of sound pollution, and helps keep your power bills low. But how do you know if you have enough wall insulation?
Homes should be insulated according to the following factors:
- Home size
- Number of floors in the house
- Type of insulation used
- Age of current insulation
The quick and simple way to check for insulation is by removing the electrical outlet or switch plate on the wall. Look to the side of the box to see if the wall appears to be empty or insulated. If it is empty, you likely need additional insulation.
Here are some other signs of inadequate insulation:
- Your energy bills go up even when your usage doesn’t.
- You feel drafts in your home as well as uneven temperatures in different rooms.
- Noises from outside are louder than they should be.
- Your home was built in the 1970s or earlier. (If this is the case, your insulation is probably not up to current standards.)
If your walls do not have adequate insulation, start looking into adding more. This is critical not just for energy efficiency but also for soundproofing between rooms and floors (especially in condominium units where people share a common dividing wall).
Before making a final decision, call out a professional to help you understand the full scope of your needs as well as your options for insulation materials. There are many choices ranging from loose-fill cellulose to batt insulation. An expert can help you choose a proper fit for your home.
