What is Keystone S/K-90 Cavity Wall Lintel 1200mm?
Keystone S/K-90 Cavity Wall Lintel 1200mm is a high-strength, load-bearing structural element designed to support cavity walls around door and window openings. It is specifically engineered to transfer the weight of the masonry above the opening to the vertical supports below, ensuring the overall stability and safety of the completed wall.
Manufactured from premium pre-galvanised mild steel, the Keystone S/K-90 lintel is built to withstand the rigours of modern construction while providing excellent resistance to corrosion. A key feature of the Keystone S/K-90 lintel is its CFC-free polystyrene core, which not only reinforces its structural integrity but also improves the thermal performance of the wall. This core reduces thermal bridging at critical points around openings, helping to achieve higher energy efficiency levels in the building envelope.
Engineered to accommodate cavity widths between 90mm and 105mm, the Keystone S/K-90 lintel is ideal for a wide range of cavity wall applications. Its robust design ensures even load distribution, which is crucial for maintaining structural stability and preventing stress concentrations. The lintel is also fire-rated for one hour according to BS 476-20:1987, contributing to enhanced fire safety within the building.
Where is Keystone S/K-90 1200mm Used?
- Cavity Wall Construction: Bridges openings in cavity walls, typically above windows and doors.
- Load-Bearing Support: Provides structural support for the masonry above the openings.
- Cavity Widths of 90-105mm: Perfect for cavity walls of this specific width range.
