Closed eaves lintels provide structural support over openings at the top of a masonry cavity wall, at the junction with the pitched roof. Lintels for eaves applications are similar in appearance to open-back lintels used in masonry cavity walls, but are designed to only support the inner skin masonry.
A closed eaves lintel distributes the structural loads of the roof, ensuring they are borne safely by the building’s external walls.
Features of closed eaves lintels
The biggest difference between closed eaves lintels and masonry cavity wall lintels is that no outer leaf masonry is built off the front toe of an eaves lintel.
The open-back design of the closed eaves lintel allows the inner leaf blockwork to continue, and the masonry must be finished with a continuous timber wall plate. The final course of blocks and the wall plate work in combination with the lintel to deliver the declared structural performance.
Continuity of insulation is essential between the external walls and pitched roof to minimise heat loss due to thermal bridging. For that reason, lintels offered for use in closed eaves applications feature integral insulation to help maintain the thermal envelope.
