Thermal Transfer


Conduction is the main cause of thermal transfer within the fabric of a building.

Conduction is the diffusion of internal heat within a body as a result of a temperature difference across it.

This is particularly important in buildings where there may be a temperature difference between the inside and outside of a building, such as in a heated building during winter. Conduction is one of the main potential heat transfer mechanisms by which the internal heating or cooling can be lost to the outside, resulting in high operating costs, high carbon emissions and occupant discomfort.

There are many features incorporated into the design of a building, such as a wall cavity to reduce thermal transfer.

With modern building techniques developing and the ever increasing use of high rise structures, a cavity and be bridged in various places.

Masonry support and lintels are a common cause of thermal bridging as the stainless steel is an excellent conductor. To eliminate this issue, ACS can supply thermal shims. These are high-density polymer shims remove contact between the supporting structure and the masonry support. This isolates the masonry support stopping heat passing through the masonry support into the internal skin of the building.
