Pyramid Aluminium launches energy-saving SlimFold

Pyramid Aluminium has launched its SlimFold bi-fold door. The product achieves a 1.4 W/m²K U-value with standard double glazing, and offers easy, clip-in beading, with a 45mm wide slimline sash. It is the latest addition to the Purelight aluminium system range.

Thanks to an innovative insulated thermal break, SlimFold doors achieve a 1.4 U-value with a Low-E, argon-filled warm edge glass unit, complying with the June changes to Part L of the building regulations. SlimFold has a super slim 45mm sash, to give a narrow 100mm meeting stile, one of the slimmest on the market. Sashes can be up to 1.1m wide and 2.5m high, to create large glass areas with minimal frames, for incredible views.

“There has always been a high demand for more glass and less frame, so we’re really excited that we’ve achieved such a slim profile to help homeowners create better views,” said Paul Bailey, managing director of Pyramid Aluminium. “The most impressive thing about SlimFold is that there is no compromise. Despite having one of the slimmest frames on the market, it still offers incredible thermal efficiency and security.

“We knew that installers were preparing for changes to Part L, so we had to create something which complied with this. The multi-point shoot bolt locking system also features two hooks and three deadbolts for extra security, so it is the perfect all-round bi-fold door option.”

The SlimFold bi-fold is built with installers in mind, with an aluminium clip-in bead making quick work of glazing, for an easy and speedy installation. Pre-delivery assembly and inspection also saves time on site.

Paul added: “On top of all the performance benefits, SlimFold is also super easy to fit. Every door is assembled on a vertical jig and inspected before delivery and our right first time manufacturing process saves customers time on site.”
