Insulation Deficit? When to Add More to Your Home

Air leaks and insufficient insulation can result in wasted energy and higher energy bills. Well sealed windows, doors and the right amount of insulation will result in an energy efficient home. In addition, the correct amount of insulation will help to reduce outside noise, improve humidity control and will improve the overall comfort of your home.

If your home suffers from an insulation deficit some of the symptoms will be rooms that are drafty, inconsistent temperatures throughout the house, high energy consumption levels and the formation of dangerous ice dams during the winter months. You can check the insulation is by looking at the level of the insulation in the attic. If the attic joists are visible, additional is required.

There are two main types of insulation that can be used to insulate the attic namely; loose fill and bat and roll insulation. Loose fill insulation requires the use of a blowing machine and an HVAC contractor should preferably be used to add loose fill  to your attic. The laying of bat or roll insulation is easier and can be done by the homeowner. Safety precautions should be taken and a protective mask and gloves are essential.

How to Correct an Insulation Deficit

  • The first step is to add insulation on top of the existing insulation. You do not have to use the same type as the isolation already in place. Ensure that the insulation cover the tops of the attic floor joists and do not cover recessed light fixtures or vents.
  • The second step is to lay fiberglass roll perpendicular to the attic floor joists.
  • The final step is to create barriers around any recessed light fixtures or vents.

Attics with a small crawlspace or with damaged floor joists can be dangerous. Rather use a professional HVAC contractor to inspect the insulation levels in the attic if it is unsafe.
