Cold bridging...Does it make a difference?

...Put simply, yes it does!

What is cold bridging?

cold bridge (sometimes referred to as thermal bridging, a thermal bridge or thermal bypass) describes a situation in a building where there is a direct connection between the inside and outside through one or more elements that are more thermally conductive than the rest of the building envelope...for example where the roof walls and floors meet, or through a lintel over windows and doors. 

Why is it important to prevent it?

The benefits of preventing cold bridging are numerous, and as such, new building regulations have placed a greater emphasis on designing buildings that do not allow for it. 

In new timber frame builds, simple design details can reduce or even eliminate cold bridging. In very well insulated dwellings, the effect that thermal bridging can have on the overall thermal performance of a dwelling can be significant. Recent research undertaken has shown that thermal bridging can be responsible for up to 30% of a dwelling's heat loss. But don't just take my word for it...

What about my existing property?

If you care about your money, your home and energy conservation, it’s important to reduce cold bridging in various elements in your home. All of the cold bridging sites in your home combined could equate to an open window, or worse, so it’s worth doing what you can to prevent it.

In existing houses we can address most sources of cold bridging. For instance in the attic space, we will normally carry the insulation over the rafter faces. Under the floor we will treat the undersides of the joists in addition to paying particular attention to the perimeter intersections to reduce cold bridging and to prevent the intake of colder air to the wall component. Other insulation installers might skimp on the detail in an attempt to save you money in the short term, but Kishorn Insulations will get the job done once, and get it done right...That's the difference.

If you’re going to pay for insulation, it’s worth doing it properly and reducing the chances of cold bridging. It’s a common misconception that cold bridging is not 100% curable, due to the design of homes, but it can actually be tackled properly if it's done correctly.
