Details

The Keystone BOX/K-100 Solid Wall Box Lintel 1650mm INS is engineered for builders and contractors working with solid walls between 100mm and 215mm thick. This insulated lintel offers reliable load-bearing support for internal openings, combining structural strength with improved thermal performance to meet modern building standards.

Application

Specifically designed for solid masonry walls, this box lintel carries the full weight of wet masonry immediately after installation, making it ideal for standard duty projects such as doorways or window openings. The insulation embedded within the lintel improves energy efficiency, helping reduce thermal bridging in your build. It’s essential to provide a minimum end bearing of 150mm on each side, bedded in mortar, and to prop the lintel during construction for safe, efficient progress on site.
