Ideas & Advice
We offer an extensive range of lintels and cavity closers to meet your construction needs.
Our lintels come in both steel and concrete, suitable for use in timber frames, internal partitions, and cavity walls. As an independent builder’s merchant, we source and supply a full array of steel and concrete lintels at competitive prices. Our steel lintels range includes metal lintels, box lintels, and hi-therm lintels, each designed for specific structural applications. For concrete lintels, we stock pre-stressed lintels, available in various sizes and lengths, starting at 600mm and increasing in 300mm increments. These lintels are cost-effective, high-performing, and CE marked, ensuring they meet stringent construction standards. In addition to lintels, we provide a range of cavity closers and trays. Cavity closers are essential for preventing heat loss, cold penetration, and moisture ingress around windows and doors. They also serve as fire barriers, enhancing the safety and thermal efficiency of your building. Whether you need standard or fire-rated cavity closers, Sydenhams has you covered.
