Technical > Insulation and U-Values


So how do the various steels stack up against each other in quantitative terms? Lets take a look:

Thermal performance is a serious consideration for any components installed in external building walls.

We are frequently asked for U-Value information pertaining to our lintels, but we cannot give thermal performance figures for our lintels in simple terms as would window or block manufacturers. This is because a lintel does not represent a uniform heat path like a pane of glass or panel of masonry.

Although we pay close attention to designing our lintels for the highest practical thermal efficiency,

The greatest thermal performance improvement to a steel lintel is to be had through careful design of the surrounding construction elements.

Minimising cold bridging effects in a typical steel cavity lintel installation:
