Insulation
Foam Injection System for existing walls
- gives the same unbeatable benefits of spray-foam
- does not require walls to be taken down
- is injected through small holes in existing interior or exterior walls
- expands to completely fill wall cavities and awkward corners
- is the perfect solution for lath and plaster walls
- is an air barrier and prevents air leakage and infiltration
- provides R-20 in a typical 2x6 wall

| A recent Injection Foam job in Victoria. Foam insulation was injected through the exterior by drilling 3/8" holes in the cedar siding. Afterwards, these holes were sealed, patched with wood dowelling and painted over. Now this house is warm, energy efficient and it looks great! | ||
Cold, Drafty Home?
Many homes in BC have poorly insulated exterior walls and a surprising amount have no insulation at all! An enormous amount of heat is lost in the winter and the home can be too hot in the summer. Even if there is some batt or blown-in insulation, hot air leaks out through cracks in the building envelope and cold drafts enter! This is reflected in your comfort, your energy bill and your home’s energy efficiency rating.
Icynene Injection Foam Insulation
If you suspect that your insulation is letting you down, call us now! Our Injection Foam Insulation for existing walls is designed to be injected through small holes in your interior or exterior walls. It then slowly expands to completely fill the inside cavity. This seals up all the nooks and crannies through which heat is lost and cold drafts enter and it provides great R-value. We use thermal imaging technology to ensure that every space is filled and there are no blockages.
Icynene Injection Foam, also known as Icynene Pour Foam, does not settle and does not need to be renewed or topped-up like blown-in or batt insulation. And unlike blown-in or batt insulation, foam insulation doesn’t lose its R-Value over time and it does not support mould growth.
Blower-door Case Studies and Energy Audits
Soon it may be mandatory for all houses in BC to undergo an Energy Audit before they are sold. Even re-insulating part of your home with injection foam can make a big difference in your energy efficiency. Blower-door tests, used in our case studies, show significant improvement in air leakage control after insulating with injection foam.
ACH, or Air Changes per Hour, is measured by using blower-door test equipment to depressurize your home and calculate the rate at which the outside air is drawn into your home through gaps in the building envelope. In a recent study, where we re-insulated some (but not all) of the walls, the ACH rate was taken from 13 Air Changes per Hour down to 6. A similar study showed an improvement from 11 ACH to 5. This is an impressive reduction of more than 50%!
The ideal target for new homes, as recommended by energy advisors is 3 ACH or better (with mechanical ventilation). Insulating your whole
home with injection or spray foam insulation will bring you even closer to this number.
There are currently incentives to improve the energy efficiency of your home. Ask your Energy Advisor or call us for more details about government grants for insulation and improved air leakage control!
