A breath of fresh air: Listers lead with Sheerline
Garnalex Sheerline is a modern aluminium window and door system designed from the ground up, painted and extruded in the UK, which promises to offer fabricators, installers and homeowners warm, slim and ultra-secure products.
“After meeting with the engineers right at the start of the Sheerline journey, I could see exactly what they were trying to do in aluminium,” Roy Frost, Listers’ MD, said. “It is a real breath of fresh air: an aluminium system designed by PVC system designers.”
The latest development from the aluminium systems company is a new state-of-the-art powder coating facility, which promises to control quality, and shorten lead times on ex-stock coloured profile, bringing them in line with PVC-U alternatives. For example, black, white and grey will be supplied by Listers on a two-week lead time, with a further nine on-trend colours available in just four weeks from Listers.
“On colours alone, the most popular are made to stock, so they are available on very short lead times,” Roy said. “Agate grey on white isn’t a stock colour in most aluminium systems. But with Sheerline, it is on a two-week lead time, which means I can offer installers the same lead time as my PVC-U products.”
Roy said many of the design features chime with him as a fabricator, for example: the requirement for less stock holding, that ancillaries work across a number of product ranges, and the revolutionary clip-in bead which dramatically speeds-up installation time.
“Also, Part L of the Building Regulations includes a reduction in U-values to 1.4W/m2K for bifold doors in refurbishment projects, and I know that many of the systems on the market struggle to meet this without expensive glazing specifications,” Roy said. “Sheerline, on the other hand, is Part L-compliant as standard.”
Thanks to the patented Thermlock® multi-chamber design, Sheerline Prestige windows can achieve U-values as low as 1.3W/m2k with a double glazed unit, 0.9W/m2k with a triple, and can accommodate glazing depths of between 28mm and 44mm. It has also been designed to reduce its impact on the environment, sourcing aluminium from Wales, extruding in the UK, and recycling all aluminium waste.
Sheerline also achieves the PAS24 security standard, and has full Secured by Design accreditation.
“The fully SBD-compliant Sheerline Lantern is a fantastic addition to our range, and it is a perfect fit with Listers’ goal of offering premium products at an affordable price point,” Roy says. “Available in black or grey, with a white interior, installers love the Sheerline Lantern, because it is probably the easiest lantern on the market to fit.
“We are also making it even easier for our customers to deal with Listers, by launching an online configurator and pricing tool at the end of the summer.”
