We set a deadline for some work to be completed by and our trusty contractors met it with zero issues.
Our electricians from DC-10 Systems were working under a tight schedule to make sure all the wiring that had to be done on exterior walls was completed because the sprayfoam was scheduled!
We hired Spraywest Inc., a company based out of Regina, to complete the sprayfoam insulation on the first and second floor, as well as the attic space of the house. We chose to go with sprayfoam insulation because it’s energy efficient and environmentally friendly.
This Polyurethane foam puts insulation, air and vapour barrier into one product.
- Insulation: “Independent laboratory tests confirm the on site long term thermal performance of POLARFOAM PF-7300-0 SOYA spray foam insulation in the building envelope system increases thermal performance of the building envelope. The long term minimum insulating value is R-6/1 ” RSI 1.05/25mm.”
- Air Barrier: “Research shows that 40% of building heat loss can be attributed to air leakage conducted through the building envelope. Tests for air leakage conducted by an independent laboratory recognized by the CCMC show that POLARFOAM PF-7300-0 SOYA exceeds 500 times the requirements of the NBC as an air barrier material.These results confirm that POLARFOAM PF-7300-0 SOYA is one of the highest performance air barrier materials on the market and this feature is the key element in an air barrier system that meets the objectives of the NBC
By creating a sealed air barrier and eliminating air filtration POLARFOAM PF-7300-0 SOYA does not allow wall condensation, that can often result in mold, mildew and wall degradation.”
- Vapour Barrier: “Water vapour permeance is the speed to which water goes through a homogeneous material. The National Building Code, stipulates that a vapour barrier must have a water vapour permeance less than 1.05 PERM (60 ng/Pa*s*m2)
- 75 mm of POLARFOAM PF-7300-0 SOYA spray applied on an exterior gypsum board = 44 ng / Pa*s*m2 (0.77 PERM)”
The easiest way to summarize the above information is: sprayfoam rocks.
The sprayfoam is quickly applied by a spray nozzle and the foam expands into place and hardens.
The crew member from Spraywest focused on the second floor of the house to begin. You can see in the image above that tape is applied to the studs. The reason for this is simple – any sprayfoam that might expand onto a stud can easily be removed, allowing for perfect drywall installation.
As the sprayfoam was being installed on the second floor, DC-10 Systems was busy on the main floor doing some electrical work. They were working on the dining room potlights.
All in all, it was a very busy and exciting day at the house! It will be so nice to be able to get some heat in there for everyone working.
