Insulation

Blow-in insulation is a very affordable way to achieve a high R-value for accessible attics. Whether upgrading an existing home or building new, blow-in is the most cost-efficient and commonly used method in Central Alberta. When preparing to retrofit your house to increase its energy efficiency, often this is the best place to start.

Spray foam can fill even the smallest cavities, creating an effective air barrier. Foam provides excellent resistance to air infiltration and prevents unnecessary leakage which may be costing you on monthly energy bills. Although it comes at a much higher cost than fibreglass, it is definitely among the most superior ways to insulate a home. It also provides solutions to insulating areas where other products cannot perform properly, such as; cathedral ceilings with limited venting, tanks, undersides of the trailer, joist cavities etc. Spray foam gives us the ability to eliminate the weak parts of the project, allowing us to provide the best quality available.

A thermal barrier is a material, applied to foam insulation, designed specifically to delay the temperature rise of the foam and prevent it from igniting in the event of a fire. Code requires all polyurethane foam to be covered by an approved thermal barrier. There are a few products available that meet the Alberta Building Code (including drywall). Please be sure to talk to one of our representatives for more information.

Batt insulation is pre-cut, fibreglass or rock wool insulation. Batt insulation can be used to insulate walls, floors, attics and ceilings and is most often fit between the framing members. Batts are available in a variety of R-values so it’s easy to achieve a wide range of efficiencies. Desired values need to be considered before choosing your framing depths in order to ensure the proper depths are achievable.

A vapour barrier is any material that resists diffusion of moisture through the walls, floors and ceilings of buildings to reduce the buildup of moisture within the assembly. The most common method is using 6mil poly. There are many factors that contribute to the effectiveness of the vapour barrier including products, install methods, framing tactics and atmospheric conditions. Specifically, in wood construction, the need to control moisture diffusion is extremely important, be sure to properly consider your vapour barriers when constructing your project.

Johns Manville Spider® Plus Formaldehyde-Free™ blow-in fibreglass insulation uses interlocking fibre technology to fill all gaps and voids quickly with no adhesive or netting for a faster installation. Spider Plus provides complete coverage, with no shrinking or settling, resulting in superior thermal performance and sound control. Designed for use in wood and metal-frame construction, engineered wood construction and manufactured homes. Spider Insulation can achieve an R24 in a 5.5” cavity!
