Details

The Keystone BOX/K-200 Solid Wall Box Lintel 2250mm INS is engineered for builders and contractors working with solid masonry walls between 100mm and 215mm thick. This lintel combines robust load-bearing capacity with enhanced thermal insulation, making it an ideal choice for internal openings where both strength and energy efficiency matter. Please note that lintels must be installed with a minimum end bearing of 150mm on each side and bedded on mortar for optimal performance.

Application

This box lintel is designed to support standard load internal openings in solid walls, commonly used in structural walls where wet masonry is applied. The integrated insulation helps reduce thermal bridging, an important consideration for building regulations and energy-conscious projects. The perforated surface ensures a strong plaster key, allowing for a neat finish. Builders should prop lintels during construction to maintain stability and speed up the build process.
