Stellar Goes Direct To Direct

Aluminium fabricator Direct Trade (Yorkshire) has started fabricating the new slim bi-fold door and lift & slide patio door from the Stellar system. The Doncaster trade supplier is clear on the advantages Stellar will offer its customers.

Stellar comes from Epwin Window Systems – better known for its PVC -U profiles.


 “The market has changed and installers are expecting more innovation from their products to sell into the consumer. Epwin has been synonymous with delivering cutting-edge PVC-U systems and that design innovation is evident in Stellar.”

– Mark Powell 

Sales director, Direct Trade (Yorkshire)



Just like PVC

“Stellar is technically ground-breaking and it’s the first aluminium system that fits like PVC-U, which will be a great bonus for our installing customers,” continues Powell. “Both Stellar doors offer incredibly slim sightlines which are popular with consumers. Furthermore, because Stellar doors have patented pre-gasketed knock-in beads, installation is far quicker.”


Energy efficiency

Both the Stellar slim bifold door and lift & slide patio door meet the new changes to part L of the building regulations with 28mm glazing. Powell says: “The changes to part L have meant some aluminium systems have needed to introduce various enhancements to comply with regulations. But Stellar was already compliant by design.”



The slimline aluminium bi-fold door is 20% slimmer than the original Stellar bi-fold and delivers superior sightlines. At just 117mm wide, the meeting stiles create an attractive sightline in the closed position. It 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 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.

The lift & slide patio door also delivers very slim sightlines to make the most of the glass area. The system’s strength allows sash widths up to three metres wide via a range of interlock sizes, as slim as 50mm, to achieve the best combination of aesthetics and size capability.
