Registered Construction Detail 2 - Steel lintel with perforated steel base plate

E1 Steel lintel with perforated steel base plate E1MCFF2

This junction can account for up to 26% of heat loss through thermal bridging, so it is critical the metal lintel is isolated from the external wall to minimise heat loss through the structure.

In this detail the registration number tells us it is detail number E1, that masonry has been used and the cavity has full fill insulation.

Key construction points

•    Check the lintel is capable of spanning the required opening.
•    Insulation generally has to be positioned inside, outside and beneath the lintel to ensure it performs adequately under Building Regulations Part L.
•    Ensure all insulation is in position before fixing plasterboard.
