Extra Heavy-Duty Cavity Wall Lintel for Large Structural Openings


The IG L5/100 Extra Heavy-Duty Cavity Wall Lintel is specially designed for significant structural support in cavity walls, ideal for large load-bearing openings such as doors and windows. Built to withstand high load requirements, this lintel offers enhanced strength, durability, and thermal efficiency, making it the perfect choice for demanding structural projects.
Manufactured from premium-grade galvanised steel, the L5/100 lintel provides superior corrosion resistance. The insulation foam layer between its flanges improves thermal efficiency, reducing heat transfer and supporting energy efficiency in the structure.

Key Features and Benefits


The L5/100 lintel is crafted for extra heavy-duty support, designed to securely hold significant loads in cavity walls. It integrates seamlessly with blockwork, with all joints filled for optimal load distribution. For added safety and faster construction, this lintel may be propped during installation. This lintel’s one-hour fire rating and BBA certification confirm its quality and reliability in demanding environments, making it ideal for structural projects where safety, strength, and efficiency are paramount.

Application Guide


To ensure optimal structural support, the L5/100 lintel should be installed level and bedded in mortar at both ends. Integration with blockwork is essential, with all vertical and parallel joints fully filled with mortar. A mortar bed should be applied over the blockwork before laying any floor units to ensure even load distribution. Propping during construction can be used to support stability and efficiency. For best results, follow all guidelines for cavity lintel installations in accordance with BS standards.

Thermal Performance and Fire Resistance


Equipped with an insulation layer between flanges, the L5/100 cavity wall lintel enhances thermal efficiency by reducing heat transfer across the cavity wall, supporting energy savings. It is rated to provide up to one hour of fire resistance, ensuring extra safety for both residential and commercial structures. Certified by the British Board of Agrément, the L5/100 guarantees high-quality performance and durability under pressure.

Choose IG Lintels for Superior Structural Support


IG Lintels are trusted across the industry for their robust, long-lasting support and energy-efficient design. The L5/100 Extra Heavy-Duty Cavity Wall Lintel offers reliability, strength, and enhanced thermal efficiency, making it an ideal choice for projects that require uncompromising quality and performance.
