Epwin Window Systems has received full patent approval for the adjustable locking stile on its Stellar Aluminium Slimline Bifold Door. This patented design further strengthens the door’s position in the market extending the unique benefits it brings fabricators and installers.
The patented adjustable slimline locking stile enhances the door’s aesthetics. At the same time, its fine-tune adjustment between the lock and the keep assists with the setting of the door during manufacturing and installation. It also eliminates the need for adjustable door jambs that complicate installation and affect thermal performance.
Neville Gleed, Technical Development Manager at Epwin Window Systems, said: “Securing full patent approval for the adjustable locking stile is another significant milestone for Stellar. This achievement reinforces our ongoing commitment to delivering advanced design solutions that give our customers a competitive advantage in a crowded market.”
The adjustable locking stile is one of a number of benefits that set the Stellar Slimline Bifold Door apart and deliver an impressive level of thermal efficiency and aesthetic appeal. It results in a bifold door that meets and exceeds the demands of modern building standards and customer expectations.
The Stellar Slimline Bifold Door meets the requirements of the 2022 Part L Building Regulations, achieving a U-value of 1.4W/m²K with 28mm double glazing and 1.0W/m²K with 44mm triple glazing.
This is achieved through features including innovative thermal break technology that has low thermal conductivity, which ensures exceptional insulation. It also benefits from tailed glazing gaskets and an under-glass seal which breaks up the cavities behind and under the glass to further enhance its thermal performance.
Aesthetically, the slimline locking stile puts all the focus on the view. And the knock-in glazing beads are easier to install and give a cleaner finish, further enhancing the door’s visual appeal.
Like all Stellar products, the bifold door is available in a wide range of Qualicoat-approved standard and non-standard RAL colours. The product is backed by a 25-year marine-grade surface paint finish guarantee for installations located within 5km of the coastline, and a 10-year guarantee for locations between 50 metres and 5km from the coast.
The system is also PAS24:2022 accredited
Neville concluded: “The Stellar Slimline Bifold Door delivers outstanding thermal efficiency and next-level aesthetics, all in a door that is uniquely easy to install. It’s simply the best in aluminium bifold design.”
