uPVC Sliding Inline Patio Door

Effortless Operation and Sleek Design

uPVC Inline Sliding Patio Door

With the Southeast Windows EnergyPlus inline sliding patio door, at least one pane is usually fixed on one side. In contrast, the other pane moves along a track, designed to look equal with an interlocking join in the centre. You can opt for a three-pane slider on two tracks for larger openings. The Liniar ModLok™ patio door system features an effortless opening mechanism with a smooth, noiseless glide, making it feel as light as air to operate. Fitted with Liniar’s revolutionary multi-wheeled ‘airglide’ system, the sliding patio door is perfectly balanced as it moves along its track.

Built-in Brushes

Liniar Inline Patio Door in White.

The built-in brushes gently sweep away any minor debris each time the door is closed, aiding its silent action. Unlike conventional patio doors that typically have only two rollers called bogeys at each end, which can drag and become difficult to operate over time, the Liniar ModLok™ patio door system is designed for superior functionality, durability, and low maintenance. Each door has eight wheels made from acetal plastic, a lighter and more hard-wearing material than steel. These self-lubricating wheels ensure smooth motion over time, requiring minimal maintenance and enhancing the door’s long-term value.

Energy Efficient Multi-Walled Profile

Choosing Southeast Windows EnergyPlus uPVC inline patio doors with high thermal efficiency is essential. The lower the U-value, the better the door prevents heat transfer from inside your home to the outside. Liniar’s unique bubble gasket ensures your doors remain draught-free. The multi-chambered EnergyPlus profile used in the Liniar ModLok™ patio door can achieve a U-value of 1.0 W/m²K with triple-glazed units. Even with cost-effective double glazing, the Liniar ModLok™ patio doors achieve a U-value of 1.2, helping you maintain a warmer home during winter.

Roy and his team fitted new windows and French doors in our house earlier this year (we wanted to live with them for a while before reviewing!). We are really pleased with the quality of the windows and the service from Roy. He's a real gent to deal with and is punctual and professional. His quote wasn't actually the lowest but he was the only one to supply full details of materials, give fire safety and security advice, send a detailed quote etc. Thank you Roy

I got quotes from a few companies however Peter was the only one who followed up to my questions on email so I decided to go with Southeast Windows. I am super glad I did, as Peter was professional and I am really happy with the work done in installing a new PVC backdoor and replacing glass in several windows. Peter was knowledgable, friendly and didn't take advantage of my lack of knowledge of window and door installation like some other builders have, being a first time home owner.I wouldn't hesitate to recommend Peter and Southeast Windows, I will for sure be using them again if I need. Thank you Peter!
