Eaves Lintels

Description

The eaves lintel has a shortened outer flange to allow the underside of the soffit board to be positioned tight against the window frame. It must be noted that brickwork cannot be built onto the outer flange of an eaves lintels. Masonry is built on the inner leaf only. The loading figures are achieved by considering the lintel and masonry as a composite unit. The Keystone eaves lintel also incorporates a thermal break plate on the underside of the lintel for superior structural performance.

Eaves lintels are insulated with expanded polystyrene and conform to BS 13163: 2008. Shortened outer flange. Integral steel plaster key for improved fire resistance. Profiled CFC free insulation.
