STAGE TWO: Building the walls using the REMOTE system

The wall we designed for the Demo House is best categorized as a ‘REMOTE’ wall, a high-performance building envelope developed by the Cold Climate Housing Research Centre in Alaska. REMOTE stands for ‘Residential Exterior Membrane Outside-insulation Technique’.

How to install cladding so your walls can dry

Monday, January 19th, 2015

The walls of your home are an environmental separator. Their job is to keep the inside in and the outside out. Exterior cladding is your first line of defense against weather elements, and its job is to allow the control layers - like your vapour barrier, air barriers and insulation to do their jobs without being assaulted by wind, precipitation and UV rays.

ecoHouse 4 - Vapour Barrier Ideas - Try mounting OSB on the inside

Wednesday, September 18th, 2013

We are currently in an evolutionary period of home construction. Climate issues, resource depletion and market demand are driving innovation in both product and building technique. The old standby wall recipe of 2×6s, glass fibre insulation and polyethylene saw us through the last few decades, but doesn’t measure up anymore with building codes, nor the trend towards high-performance housing.

ecoHouse 4 - A New Brunswick first - Passive House debut scores 95% energy savings

Wednesday, September 18th, 2013

Nestled behind a line of trees in Douglas New Brunswick and overlooking the Saint John River is the cedar-clad home known as Naugler House. The two-level retirement home, the first Passive House in the province and constructed by the owner’s son Tim Naugler of Southern Exposure Construction Inc., delivers year-round comfort that a Passive House provides.

ecoHouse 3 - Build a ‘Poly-free’ house: just paint on your vapour barrier

Tuesday, June 25th, 2013

When you treat air barriers and vapour barriers as the completely separate wall components that they are [see EcoHouse Spring 2013 issue], you can plan them individually and explore options beyond the standard polyethylene vapour barrier. In order to really explore this idea, it is important to first envision a ‘vapour barrier’ not as a specific product, but rather as a concept. Your ‘vapour barrier’ is the means by which you control vapour diffusion, and there is more than one way to do that. Traditionally, a 6 mil [15mm] polyethylene vapour barrier is installed behind the drywall in new Canadian homes. In fact, you would be hard pressed to find a home being built in Canada right now that does not have it, or something equally impermeable to water vapour. This is an ideal building practice in the Arctic and Subarctic communities in the northern reaches of the country; less so as you come further south.

Product choices and considerations for energy savings

Thermafiber’s Mineral Wool Insulation contains over 80% recycled content and helps projects qualify for LEED Green Building Credits.

.

Insulation is only one component of many in the building envelope - but arguably the most critical one in determining energy savings and interior thermal comfort. Every aspect of the envelope design must be considered including the air tightness and the positioning of windows within the thickness of the walls. (more…)

Tornados, hurricane spin-offs, torrential rains, floods, heat waves and ice storms.
As such incidents become more common in Canada, the ability of structures to withstand the effects of extreme weather is of growing importance to designers and builders. (more…)
