Description The IG Heavy Duty Steel Cavity Wall Lintel L1/HD100 is a heavy-duty load-bearing lintel specifically designed to support openings in cavity walls with widths ranging from 90mm to 105mm . This lintel is ideal for structural applications, such as load-bearing cavity walls and openings for windows or doors. Key Features: Heavy-Duty Load Support: Suitable for supporting significant loads above openings, distributing weight effectively across the structure. Cavity Width: Designed for cavity widths of 90-105mm. Material: Constructed from pre-galvanised mild steel, offering strength and durability for long-lasting performance. Thermal Performance: Insulation foam between the two flanges improves the thermal performance of the lintel, reducing heat transfer and improving energy efficiency. This lintel is a reliable solution for structural projects requiring load-bearing support for cavity wall openings, offering both strength and thermal efficiency.
