Details

The Keystone BOX/K-150 Solid Wall Box Lintel 2400mm INS is a reliable structural solution for builders and developers working with 150mm solid walls. This insulated lintel offers improved thermal performance, making it a smart choice for internal openings where both strength and energy efficiency are priorities. Please note the lintel is supplied in 2400mm length increments and must be installed with correct bearing and bedding.

Application

Specifically designed for internal openings in solid masonry walls between 100mm and 215mm thickness, this box lintel carries the full wet masonry load immediately upon installation. It is ideal for standard load-bearing scenarios such as doorways and window openings in residential and commercial projects. The integrated insulation enhances energy retention, supporting compliance with modern building regulations. Proper installation requires at least 150mm bearing at each end, bedded on mortar and ideally propped during construction for faster, safer build times.
