Birtley CB70 Cavity Wall Lintel – 1800mm

Birtley CB70 is a high-performance cavity wall lintel designed for standard duty loading in construction projects. This lintel is specifically crafted for cavity wall construction with a cavity size range of 70mm to 85mm, making it an excellent choice for both trade professionals and DIY enthusiasts. The unique design eliminates the need for a baseplate and features factory-fitted insulation, which effectively reduces thermal bridging for better energy efficiency.

Moreover, the advanced Supergalv coating enhances the lintel’s durability, providing a superior life expectancy and ensuring ample protection against corrosion. For lintels exceeding 1500mm in length, it is essential to prop them until the masonry is fully loaded and cured to maintain structural integrity. This makes the Birtley CB70 not only reliable but also easy to work with on various building projects.
