Birtley Supatherm ST110 Thermally Broken Cavity Wall Lintel — 110–125mm Cavity | 1800mm
The Birtley Supatherm ST110 (SKU: ST1101800) is a standard duty thermally broken cavity wall lintel designed for 110–125mm cavity construction. Delivering up to 80% reduction in heat loss compared with standard cavity wall lintels, the Supatherm range is engineered to help meet Part L Building Regulations and the Future Homes Standard without compromising structural performance.
At 1800mm in length and 21.36kg, the ST1101800 suits wider standard openings in domestic masonry construction and avoids the propping typically associated with single leaf lintels.
Note: Not suitable for point loads or concrete floors.
