Sheerline: Part-L-compliant aluminium as standard

Tougher Part L requirements don’t need to be a cause of concern for suppliers of aluminium products. In fact, if you choose the correct system supplier, these tighter standards can help give you an edge in a market that’s set to become more competitive as the cost of living crisis begins to encompass more middle income households.

With an ever-expanding range of Part-L-compliant aluminium windows, doors, bi-folds and roof lanterns, Sheerline’s customers are reaping the benefits of choosing a modern aluminium system, its representatives have claimed. Products are designed around Sheerline’s Thermlock technology, which sits at the heart of every product.

Thermlock multi-chambered thermal breaks are made from a material that is almost half as thermally conductive as polyamide. This, coupled with their increased size, means that Sheerline meets the new standards with standard double glazing, helping customers continue to sell the same spec’ of products, without adding cost. With Sheerline, an aluminium U-value of 1.4 comes as standard.

While other systems companies may be busy trying to shoehorn a solution into their legacy systems, either adding cost via foam inserts or forcing customers to upgrade to expensive triple glazing to meet new standards, Sheerline customers are left with a competitive advantage and a clear, easy-to-understand product offer, the business behind the brand has argued. Sheerline customers can also be confident that when thermal requirements tighten even further in 2025, as part of the Future Homes and buildings standards, the business will be ready once again to succeed in an ever-changing marketplace, they say.
