Cavity Wall Lintels

Cavity Wall Lintels

Cavity wall lintels are considered to be suitable for most domestic, commercial developments and framed structures.

A cavity lintel is designed to be used when two layers of bricks and blocks, or ‘skins’ are used to construct a space or cavity between the structure. The in-built polystyrene or foam insulation helps to retain warmth and reduce condensation.

Our key suppliers are Birtley Steel Lintels and Keystone Lintels. All our steel lintels are galvanized to protect against premature rust and corrosion and meet the Thermal Performance requirements of all UK Building Regulations.

The NHBC (National House Building Council) recommend a damp-proof course (DPC) or cavity tray should be installed over all openings in external cavity walls.

Buildbase have a large range of standard lintels for cavity walls, which are available in a variety of widths ranging from 70mm to 165mm and lengths from 900mm to 3900mm. For thicker steel and when a longer span lintel is required, Buildbase has a range of medium and heavy-duty lintels for 90-105mm cavity widths which are stocked in lengths from 1200 to 4800mm.

For more information on our lintels please check our how to guide. However, before ordering a lintel, it is essential that you speak with the project’s structural engineer to advise on the correct lintel for the job.
