Where Should Thermally Broken Systems be Used?
As steel systems are a more traditional framing material many of the systems available on the market were developed many years ago (before modern thermal performance requirements were put into place) and therefore there are many steel systems available that are non-thermally broken. Therefore there are a lot of house and projects are waiting for upgrade.
For usable ,warm environments a thermally broken system to all external framing is a must. Aside from the relevant Uw values required by modern building regulations, using a non-thermally broken framework to an internal space can lead to freezing on the internal framing in colder months and condensation build up internally on the cold metal surfaces. This can lead to mould and damp to build up on internal building finishes such as real wood flooring and curtains.
In short, thermally broken systems should be used anywhere there is a difference in climate on either side. This could be between inside and outside, but it could also be between an in indoor swimming pool environment and a living space.
