Epwin Window Systems launches new Stellar Slimline Bifold Door

22 June 2022

Epwin Window Systems has further expanded its aluminium system portfolio with the launch of its new Stellar Aluminium Slimline Bifold Door. By design, the Stellar Slimline Aluminium Bifold Door is 20% slimmer than the original Stellar Bifold and delivers superior slim sightlines at every level. At just 117mm wide, the slim meeting stiles create an attractive sightline in the closed position, letting the glass take centre stage for maximum customer appeal.

As you would expect from a Stellar product, the intelligent design protocols and patented features are evident throughout the door. This includes patented pre-gasketed knock-in beads that make glazing the Stellar Slimline Bifold Door straightforward. And because the beads are pre-gasketed, they leave a neat, clean gasket line on the inside for exceptional aesthetics while preventing gasket overstretch, which can be common on aluminium bifold installations.

The new Stellar Slimline Bifold also benefits from tailed glazing gaskets and an under-glass seal which breaks up the cavities behind and under the glass to enhance the thermal performance. And installation is further improved due to the unique patent-pending adjustable locking stile, so the clearance between the lock and keep can be adjusted to take up cutting tolerances, eliminating the need for adjustable door jambs.

Commenting on the introduction of the new Stellar Slimline Bifold Door, Paul Booth, Design Director (aluminium) at Epwin Window Systems, said: “The new Stellar Slimline Bifold delivers slim profiles and is packed with unique features to give our customers a competitive edge in the crowded aluminium bifold market. These unique features include the patent-pending adjustable slimline locking stile which is a real game-changer for installers allowing straightforward adjustment on site.”

Its future-proofed design delivers excellent thermal efficiency and its innovative polyamide thermal break technology delivers low thermal conductivity and ensures this high-quality door is also highly insulating. It also exceeds the requirements of the 2022 Part L Building Regulations achieving a U-value of 1.3W/m²K with standard 28mm double glazing and 0.9W/m²K with 44mm triple glazing. The system is also PAS24:2016 accredited with a Secure by Design option too.

The new Stellar Slimline Bifold is available in a range of standard and non-standard RAL colours each with a 25-year surface paint finish.

The new Stellar Slimline Aluminium Bifold is impressive and is already proving popular with early adopters of the system. Paul concludes: “The new Stellar Slimline Bifold has all the strength a bifold door needs and packs a punch in system design. Its slim sashes, expansive glazed area and contemporary aesthetics are next level. Add in its easy installation and swift fabrication and you have the best in aluminium bifold design. A door that was designed in Britain for British homes. It’s a powerful proposition.”

The Stellar Slimline Aluminium Bifold Door is part of the multi-award-winning Stellar aluminium window and door system from Epwin Window Systems, the UK’s largest systems house.
