Attic Insulation

Greensaver has insulated thousands of attics in the GTA and surrounding areas. Our services include:

  • The modification of insulation to meet the current code.
  • The removal of existing insulation.
  • The addition of new insulation.

Spray Foam Insulation

Greensaver offers 2 lb closed cell and ½ lb open-cell spray foams for attic insulation. Both options are high-quality insulations that inhibit mould growth and expand to provide a continuous barrier, resulting in a comfortable living environment.

2 lb closed cell spray foam is an all-in-one insulation that provides a high level of insulation plus an excellent air and vapour barrier for exterior wall, floor and roof surfaces. This type of spray foam is also an ideal way to insulate ductwork in unconditioned spaces such as attics. 

In contrast, ½ lb. open-cell spray foam does not act as a vapour barrier. However, it is a great air barrier and effective at reducing sound transmission. 

We only use 2 lb spray foams made with renewable vegetable oil and recycled plastics, and that have a low Global Warming Potential (near 0).

Our experienced installers are thoroughly trained and certified by the Canadian Urethane Foam Contractors Association (CUFCA) and adhere to all proper spray foam processes and protocols.

Cellulose

Cellulose insulation is composed of recycled paper products that have been treated with additives to make them fire and rodent-resistant. It is environmentally friendly and available for roof and attic spaces.

Dense-packed cellulose is an effective method for insulating existing walls and roof cavities through holes created from the interior of the house. Greensaver uses the state-of-the-art tubing method to fill cavities, which significantly reduces cold spots and air movement. In addition, we drill all the holes required and fill them afterwards, which sets us apart from other insulation companies.

Narrow Cavity Pour Foam Insulation

Greensaver offers this services for double brick and brick/block walled homes with narrow, uninsulated cavities. This is a 2 lb closed cell pour foam product that is installed through holes drilled from the interior of the house, similar to our dense packed cellulose method above. The cured foam provides high insulation value/ inch, acts as an air barrier and inhibits mould growth due to its low vapour permeance.
