Tradelink adds Smart Alitherm 400

Tradelink added the Smart Alitherm 400 system to its range of aluminium solutions, in a move aimed at addressing the latest building regulations, its representatives have said. Tradelink is marketed as the UK’s leading supplier of doors and windows to the trade. The supplier’s representatives described Smart Alitherm 400 as suitable for commercial contracts as well as new-build and refurbished residential properties.

Offered in flush or chamfered styles, and with a wide choice of colours as well as hardware options, the Smart Alitherm 400 is also marketed as the first thermally broken aluminium system to feature the manufacturer’s coextruded glazing gasket. As quick-glaze beads are supplied with the gaskets post-extruded into the profile, the fitting process for this product is quicker, they say, as it can be simply tapped into place on site.

The weather and thermal performance of Smart Alitherm windows is matched by Smart Alitherm 400 doors, which are available in both single and double options, as well as open-in or open-out configurations. Smart Alitherm 400 can be combined with Smart’s designer door panels and the company’s range of standard door furniture too, including colour-matched lever handles and the Quantum range of stainless steel hardware.

Stuart Walker, the divisional head of special projects for Tradelink, said: “The Smart Alitherm 400 is an advancement on the 300 system and responds to the latest changes in building regulations, Part L, making it possible to meet the enhanced requirements. Now, with the new standard offering, you can achieve a U-value of 1.6 W/m²K and an ‘A’ energy rating, without upgrading to triple-glazed units. This means it meets the new limiting value for new-build work as well as the energy rating for replacement projects.

“Having the gasket already integral to the extrusion definitely offers a time- or labour-saving benefit to the installer, and brings aluminium back in line with PVC-U alternatives. The combination of better thermal performance and improved installation characteristics, as well as the excellent security and stylish appearance, makes the Smart Alitherm 400 an attractive proposition for our trade customers serving the commercial as well as residential sectors.”

The Smart Alitherm 400 range of doors and windows is available with a lead time of three to four weeks. Across its production base in Cambridgeshire, Tradelink has invested in increased stockholding to ensure its operations are more resilient and can keep up with customer demand, its representatives have said.
