Birtley Medium Duty Cavity Wall Lintel 100mm CB90HD

The Birtley Medium Duty Cavity Wall Lintel 100mm CB90HD is engineered for superior performance in cavity wall constructions. Designed for cavities between 90-105mm, this lintel features a 100mm outer and inner leaf, making it ideal for medium-duty applications. With a 60-minute fire rating and compliance with BS EN845-2:2013+A1:2016, it combines strength, safety, and reliability. The absence of a baseplate and factory-fitted insulation reduces thermal bridging, while the Supergalv coating extends its lifespan. Trusted by professionals, the Birtley CB90HD lintel is a top choice for robust and efficient cavity wall solutions.
