The Catnic Thermally Broken Cavity Wall Lintel TS90/100 sets a new standard in cavity wall construction with its innovative thermal break, designed to enhance energy efficiency. Built from robust steel, this lintel provides reliable support for masonry, timber floors, and roof loads typical in most buildings, making it ideal for fair-faced inner leaf masonry applications. The open-back profile simplifies the construction process, allowing continuous masonry build-up across both inner and outer leaves. Available in standard, heavy, and extra heavy duty, it accommodates cavity widths from 90mm to 205mm. This fully insulated lintel features a complete thermal break, an integral plaster key, and Catnic’s signature black powder coating for a long-lasting, professional finish.
