Details

The Keystone HDBOX/K-100 INS is a robust, heavy duty box lintel designed specifically for 100mm solid wall applications where strong structural support is critical. Ideal for builders and site managers working with concrete floors or significant point loads, this lintel incorporates insulation to enhance thermal performance without compromising strength. Please note, lintels must be installed with adequate bearing and bedding to perform correctly.

Application

This lintel is perfect for supporting openings in solid masonry walls, especially when heavy loads from above, such as concrete floor slabs or concentrated point loads, need reliable transfer. Its insulated design helps maintain energy efficiency standards on site, making it a smart choice for both new builds and refurbishments requiring structural integrity and thermal compliance. The perforations along the lintel’s length assist plaster adhesion, aiding a clean finish.
