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.
