The timber frame structure is the most visible and often praised feature of a timber framed home, however the walls and roof that surround the frame are just as important.  We don't get as emotionally attached to the materials buried in our walls once they are covered in drywall - but we should.  With energy costs rising and the environment increasingly under attack, our objectives for building your walls and roof are simple:  Make the thermal envelope of your home as energy efficient as possible, using the most benign and ecological materials widely available on the market today. 

Our Intelli-SHELL pre-fabricated wall & roof system addresses many of the concerns we have with the way homes are being built, both conventional and timber frame.  Here are some of the innovative features of our thermal envelope:

  • 2" x 8" wall thickness as standard, using injected cellulose insulation achieving R-28.  Cellulose is recycled newspaper, and fills every crack & corner of your wall cavities far more effectively that batt products, like fibreglass.  It's also inert, hygroscopic, and has 85% recycled content.  It is treated with natural products to prevent fire & rodent infestation.  It does not settle in the walls as it is pumped in under 3 to 4 pounds of pressure. 
  • Aluminum foil backed vapour barrier used as standard.  The foil backing on the vapour barrier reflects 95% of the existing radiant heat back into the house during winter months.  This is such a simply way to increase heat retention, it's a wonder it's not used by more companies.
  • 2" x 4" horizontal furring strips on inside of home.  By using 2x4" firrings instead of 1x3", your electrician will be able to attach all of his electrical boxes and wires without penetrating the vapour barrier and disturbing the insulation.  This greatly increases the home's air tightness.
  •  All pre-fabricated wall panel joints, connections to the subfloor, and window and door gaps will be sealed with large diameter EPDM rubber gaskets, imported from Europe.  The standard practice of using 3 mm foam sill-plate gaskets and expanding foam to seal joints between wall panels or stuffing fibreglass around doors and windows is very outdated.  It won't keep the cold air out, especially when site conditions are cold or wet which prevent the effective use of expanding foams.
  • Roof panel system built to R-40 standards.  We use a few different methods for insulating the roof, depending on the timber frame design and finished roof material.  All roof panels are sealed with EPDM gaskets instead of expanding foam for better long term air tightness.
