Wall Insulation

Older homes built before 1970 have little or no wall insulation which leads to uncomfortable drafty rooms and high energy costs.

Insulating your walls using our Dense Pack Process can reduce air leakage by 20-30% saving you on your energy bills and making your home feel more comfortable.

We install both JM Spider Insulation and cellulose insulation in our Dense Pack process.

What Does Dense Packing Mean?

Dense Pack refers to a process whereby loose fill fiberglass insulation JM Spider insulation is installed at densities greater than 3.0 pounds per cubic foot, through small holes drilled on the inside of the exterior walls.

Enerliv’s Dense Pack wall insulation process is a superior home insulation solution. It is the best quality solution with the highest level of R value per inch. The JM Spider material used in our Dense Pack process is a very fine loose fill fiberglass which is Government approved by the Canadian Construction Materials Centre (CCMC).

Using our Dense Pack process for retrofit wall installations we can provide a high R-value of 3.85 per inch or 15.4 in a standard wall cavity with JM Spider insulation creating a very good barrier for drafts.

The innovations of our Dense pack process enable us to provide an insulation solution for most older homes. This includes homes which are partially or inadequately insulated such as those built between the mid 1940's and the late 1960's

A Moisture Free Product and Process

We do not use any water during our Dense Pack process. This ensures that you are not left with any water moisture trapped in the wall cavities of your home. Review our wall photo gallery for examples. The fact that we are able to achieve such high insulation densities through such very small holes is a real testament to our innovative process and sets us apart from the competition.
