Energy Plus Roof Insulating System:

A roof deck of tongue and groove boards is supported on the timber rafters and provides a pleasant interior finish.  Above the deck a vapour barrier is carefully installed and up to 9-1/2” of R36 foam is laid into place across the entire roof surface.  The large (4’ x 16’) foam sheets are sealed with low expansion foam.  2”x4” strapping is then laid over top of the foam sheets and screwed down to the roof deck and rafters.  The roof is now ready for steel roofing or can be sheathed with oriented strand board and shingled conventionally.  The result is great insulating values, no thermal breaks and a roof that costs substantially less than a comparable SIPs type roof.

Energy Plus Wall Insulating System:

Some contractors, regrettably, place their best insulation on the outside of the wall and this creates an opportunity for moisture and warm humid air to become trapped inside the wall system, increasing risks, over time, to occupant health and the home’s structural integrity. The Energy Plus approach is to place the vapour barrier and 2” of high density SM type insulation to the inside of the framing wall.  Additional fibreglass insulation or a wide variety of void filling insulations can be installed between the wall studs.  Exterior sheathing and a rain barrier complete a drier, more durable and better insulated wall.
