Choosing windows - which window frame? wood v aluminum v vinyl

...insulated and more durable now, air seals are better, and gas-filled cavities between double and even triple panes are the norm. You will always have a net heat loss on northern facing windows, but high quality southern facing windows can actually offer a net gain through passive solar heat collection. Passive solar ...

Air barriers are essential to a properly functioning wall system
Air and vapour barriers

What is an air barrier?

...insulated structural sheathing: Worth noting first - as a material, OSB (oriented strand board) is an effective air barrier. And if the joints are sealed properly it also acts as a vapour barrier, which is a no-go on the exterior of homes anywhere in Canada, as you will trap moisture inside your wall assembly.ng w ...

Efficient home design, or how to design a home to use less energy

The principles of green building: High performance, energy efficient Eco homes may include features like geothermal heating, wind power and solar panels, but these are not the defining features of green living. They come in second, and some you can even do without. A green home starts with being well-designed, well-...

Free home energy audits in Canada

...insulated, the level of attic insulation, the quality of your windows, and a blower door test to see how much heat loss there is from air leaks . A blower door test identifies air leaks for repair to make homes more energy efficient. Are energy audits free for Canadians? Energy audits for government green hom...

Which is better, OSB or Plywood for Roofs, Walls & Floors?

...Insulated OSB & Ply sheathing products: Here is where it gets even more complicated. Though there are differences in provincial Building Codes, changes were made to the Canadian National Building Code in the last few years to add the requirement of a seamless thermal break to building envelopes and a higher total R v...

Choosing a building envelope - starting with the perfect wall

...insulated, more airtight and, most importantly, with better ventilation like HRV's or ERV's or air conditioning. There is also much more understanding of how buildings work and why walls can fail in a home with air conditioning, even when built to code . For example, if a home is built of timber and will be air condi...

Farnham Avenue House

...insulated wood-frame walls with polyiso foil-faced insulation panels [with zero HCFCs] eliminates thermal bridging, and helps the walls to achieve R-35. As described earlier, natural ventilation in the summer reduces energy needs for cooling. We sourced some salvaged materials for the beauty they would bring to the p...

...insulated with batts, but the majority of insulation is on the outside of the sheathing, this way the vapour control layer is sandwiched between layers of insulation where it can perform best in a wildly varying climate like we have in Canada. There are many advantages to this system - it provides much greater therma...

Should I Build on a Slab on Grade Foundation or a Crawl Space?

...insulated slab of concrete resting on high-ground with a frost-protection skirt will outlast a house built on a crawlspace; full stop. • EPS foam can be used as a vapour barrier when installed with multiple layers and offset joints as it will not absorb moisture from the ground. • Building on high ground eliminates...
