Concrete lintels

As an alternative to the use of steel lintels reinforced concrete lintels may be used to support the separate leaves over openings. This construction may be used where the appearance of a concrete lintel over openings in fairface brick is acceptable and where an outer leaf dense concrete 0f brick or block is to be rendered to enhance protection against rain  penetration or for appearance sake. insulation board ^ ranSe of precast reinforced concrete lintels is available to suit the in cavity carried widths of most standard door and window openings with adequate down to head anowance for building in ends of lintels each side of openings. For use with fairface brickwork the lintel depth should match the depth of brick course heights to avoid untidy cutting of bricks around lintel ends.
