SEAL with certainty.
2 lb SPF placed at all insulating join transition areas is the sure way to lock out internal vapour from the building envelope. At the same time achieve R5.5 per inch insulation and add extreme bonding. Applying SPF to our A-Plex join transitions we deliver a truly hybrid system COST optimized to perform at the highest levels. Ideally we apply SPF immediately following the A-Plex installation before windows and doors go in. Once the windows and doors are installed and sealed the home is ready for a mid construction air tightness test with easy access to check critical areas. In only minutes, all of those leaky join lines are vapour and air sealed -saving many days effort while achieving extreme airtightness that meets or exceeds Passive Haus standard.
We are also available for new and renovation spraying of transition areas. For larger wall and roof areas we can refer you to a reliable larger system spray foam applicator.
The age factored R-value of 2 lb SPF is R5.5 (over R-6 initially) so SPF is an excellent insulator just slightly higher than our Graphite-EPS foam sheets.
SPF is an excellent way to seal any new construction area. Spraying rim board areas of floors is the prime heat loosing space in a well built code minimum home. We recommend in excess of R20 in this area and it can be achieved with a small layer 3.5" or 5.5" fibreglass or rock wool batt then a covering of 2" of SPF. This locks out air leaks and bug ways, and at 2" also provides a vapour barrier on the inside side of the home.

SPF is an excellent way to seal any new or existing construction area. Rim board areas of floors are a prime heat loosing space and in seconds it can be perfectly air sealed and insulate to R24 and free of bug and mouse ways. We recommend excess of R20 in this area and it can be best achieved with a small layer 3.5" or 5.5" fibreglass or rock wool batt then a covering of 2" of SPF. This locks out air leaks and bug ways, and at 2" also provides a vapour barrier on the inside side of the home. The cavity shown in the video has zero insulation -but it could have had a layer of fibreglass applied beforehand.

Our SPF (Spray Polyurethane Foam) system is a small portable unit that allows us into the smallest of areas as we move the whole mixing machine with us. Our spray unit is not intended for spraying large volumes of wall or roof cavities, but is perfect for the adjoining edge areas of our A-Plex system. The volume of 2 lb spray foam required to seal our A-Plex systems is very low since all of our cavities are 100% filled and the Silverboard barrier is performing on the larger areas for vapour barrier so we use it to edge seal.
