Thermally broken lintels minimise heat transfer through the building envelope to meet Part L of the Building Regulations.
Catnic’s thermally broken lintels use two folded steel sections bonded to a high-strength, thermally efficient core, achieving psi values no greater than 0.05 W/mK without additional brackets or cold bridges.
Traditional steel lintels create significant thermal bridges by crossing the insulated cavity.
Separating the inner and outer steel sections breaks this thermal convection and reduces heat flow by over 90%, depending on the design.
Catnic thermally broken lintels are available to suit 90-205mm cavities, in standard, heavy or extra heavy-duty load capacities.

Summary
❄️ Thermally broken lintels slash heat loss by eliminating cold bridging.
📐 Fit cavity widths up to 225 mm, with future options for arches and bays.
✅ Independently verified with BBA certification and BRE thermal modelling.
🛠️ Powder-coated steel for strength and durability, with installation guidance.
📊 Free structural calculations and lintel schedules from Catnic.
🌍 Central to a “fabric first” approach — boosting efficiency before adding tech like heat pumps or solar.
