Designed for use in external cavity walls, these lintels support brickwork and blockwork over openings such as doors and windows. They are available in a range of load capacities, including standard and heavy-duty models, and feature integral insulation for enhanced thermal performance. Their corrosion-resistant finish ensures long-term durability, while easy-to-follow installation guidelines make them a practical solution for all types of cavity wall construction.

Timber Frame Lintels

Engineered specifically for timber-framed buildings, these lintels accommodate movement within the structure and offer a lightweight solution that delivers dependable support. They are ideal for maintaining air-tightness and thermal continuity in timber frame designs and are available in various profiles to match specific structural requirements and architectural aesthetics.

Box and Solid Wall Lintels

These are ideal for use in solid brick or block walls, often seen in interior load-bearing applications or traditional builds. Designed to carry heavy structural loads, they provide dependable strength and rigidity. Their simplicity and versatility make them suitable for refurbishments as well as new builds where cavity insulation isn’t present.
