What is a thermal bridge and why is it so important to break it?

...thermal bridges: It is not only sensible to address thermal bridging in construction, it is becoming law. Recent revisions to building codes have increased the thermal requirements of building enclosures in many regions, including requiring a thermal break. Contrary to common assumptions, the insulation value...

Finishing the exterior of an insulated slab-on-grade floor

...thermal bridging. What we decided on was plastic straps that passed through the cement board and that were anchored in the concrete. It did hold as planned, though there is more play in it than we ideally would have liked and if we were to do it again we would increase the amount of fasteners. Like many things, this ...

Installing doors & windows for the best performance in high efficiency homes, LEED & Passive House

...Thermal bridging and poor quality windows can make it quite unpleasant to be near exterior walls on the really cold days. How window placement effects thermal bridging Thermal bridging around windows and doors results in loss of energy , cold spots, condensation points and potential wall damage. To demonstrate th...

The Yukon's First LEED Certified Home

...thermal bridging Greywater heat recovery system Electric baseboard heaters (98% of Yukon electricity is renewable) Heating costs are 50% lower than an R2000 home Results like we are seeing here go a long way to dispelling the myth that building green homes costs more. And as news spreads of how little it cost...

Properly insulating basements and concrete slab floors

...thermal bridging. Building code requirements for foundation walls vary across the US and Canada, and range between R19 and R24.5. This is a minimum and, depending on location and climate we would recommend increasing that in the interest of saving energy, and money in the longterm. When renovating or building a new...

Our top tips for buying high-performance windows

...thermal bridging, which causes heat to be conducted through the wall framing via the window frame. This can be best achieved by centering windows in the wall rather than having them flush to the outside as we most commonly see. Eliminating thermal bridges lowers the risk of condensation, which in turn ensures longer li...

How wood structures compare to steel and concrete for Carbon Footprint

...thermal performance, vapour or air movement through wall assemblies. Concrete makes it possible to design very robust and durable buildings, and taking advantage of its thermal mass by keeping it inside the building envelope can help regulate interior temperatures. There is also an increasing use of precast concret...

How to design for thermal comfort in a home

...thermal bridging, sealed against air leaks, triple-paned windows, humidity control and properly designed heating, cooling and ventilation equipment , to name a few. Thermal comfort = efficiency and durability: The less heat that is lost through the building enclosure, the warmer it will be, and less heat will be ...

how to build a slab-on-grade on standard soil

...thermal bridging and heat loss. This technique also requires a second trip with a concrete pump truck, which depending on your region can run anywhere from $700 to $1000. Instead, what we have done here is known as a 'monopour', where the footing and slab are poured at the same time. Here are the basic steps for slab...

How insulation works

...thermal bridge', and preventing it is known as a 'thermal break'. Heat loss through thermal bridging When we mentioned at the beginning that these factors can work in conjunction, that is because the cold surface that results from the high conduction through wall studs and other thermal bridges can absorb radia...

Choosing a building envelope - starting with the perfect wall

...thermal bridging. To see the choices in lumber for a timber frame building or home, see here . Keep in mind how important it is that the cellulose be well-packed to avoid settling and leaving you with empty pockets at the top of the walls. For this reason we recommend having it installed by pros, and well-experienced...
