Trade fabricator Heritage Trade Frames has reported a strong increase in demand for the Stellar Inline Sliding Patio Door, with sales rising by 30% since the product was introduced in early 2024.
Lee Darcy, sales and marketing manager at Heritage Trade Frames, said the growth reflects increasing demand for contemporary slimline aluminium doors combined with the product’s strong installer-friendly credentials.
He commented: “Since adding the Stellar Inline Sliding Patio Door to our range in early 2024, demand has grown steadily. Installers are looking for aluminium sliding doors that deliver slimline modern aesthetics, strong thermal performance and straightforward installation and the Stellar system ticks all those boxes.”
The Stellar Inline Sliding Patio Door features a slim aluminium profile and a central interlock of just 35mm. The system supports sash widths of up to 1675mm and configurations of two, three or four panes, allowing installers to offer homeowners impressive glazed openings of up to 6500mm wide.
Performance credentials are equally strong. The door achieves U-values as low as 1.4 W/m²K with double glazing and 1.0 W/m²K with triple glazing, helping installers meet the latest Part L thermal efficiency requirements, while PAS 24 security and excellent weather performance provide additional reassurance.
Lee added: “The clean, flush appearance and slim sightlines make the door extremely attractive to homeowners who want to maximise light and open-plan living spaces. For installers, it’s a product that’s easy to install while delivering a premium finish.”
Fabrication efficiency was also a key consideration in the system’s design. The direct glazed fixed light removes the need for a dummy sash, helping reduce fabrication time and streamline manufacturing processes. Pre-inserted gaskets and patented knock-in beads further simplify installation while ensuring a neat gasket line and consistent high-end finish.
Installers also benefit from Heritage Trade Frames’ reputation for service and reliability. All products are manufactured across the company’s three fabrication plants in Bolton, supported by continued investment in machinery, training and operational systems to ensure customers receive consistent quality and dependable lead times.
Lee concluded: “Installers want products that are easy to work with, perform reliably and look fantastic in the finished project. The Stellar Inline Sliding Patio Door delivers on all three, which is why we’ve seen such strong growth since adding it to our range.”
