That’s a lot of toing and froing!

Designed With You In Mind

The reputation of patio sliding doors has improved greatly over the years and the Liniar patio sliding door will not disappoint. So as not to detract from the beautifully slim lines of the door, it features a built-in decelerator and hidden ‘Crash Stops’. Patio door panels are heavy, due to the amount of glazing they carry, so you’ll find these clever little ex-tras a blessing – especially young or elderly users.

In addition, House of Windows patio sliding door features the patented ModLok™ system, a combined reinforcement and multi-point locking system designed in partnership with Yale, one of the world’s leading lock brands.

Designed with YOU in mind, the security system features four hook bolts, two shoot bolts at the top and bottom of each sliding pane, optional anti-snap lock cylinders and anti-lift technology, providing peace of mind that your home is protected from oppor-tunist burglars.

Not only that the locking mechanism design ensures that the four hook bolts never protrude into the room even when the door is open. This alleviates the potential danger of little ones trapping their fingers when they are ‘running in and out’.

We’ve Got You Covered - Quality Guaranteed

House of Windows sliding patio doors come with a 10 Year Guarantee against cracking, warping or discolouration. The ModLok™ locking mechanism includes a 10 Year Mechanical Warranty.

uPVC sliding patio doors are large glazed doors that slide horizontally along a track rather than opening in or out on hinges. This makes them a practical, space-saving alternative to French doors, which need clearance to open, and a simpler alternative to bifold doors, which fold and stack to one side. For many UK homes, sliding patio doors are ideal for maximising glass area, natural light and garden views while keeping operation smooth and straightforward.
Modern uPVC sliding patio doors operate using precision rollers that allow the glazed sash to glide smoothly across the track. House of Windows uPVC patio doors use a Liniar system with an eight-wheel steel acetal roller mechanism, helping even larger door panels move easily and quietly. This makes them a practical choice for homeowners looking for easy-to-open, low-maintenance patio doors.
Yes, uPVC sliding patio doors can be an excellent alternative to a traditional back door, especially if you want more natural light and a wider opening to the garden or patio. Because the door slides rather than swings open, it also saves valuable floor space inside and outside the home. This makes sliding patio doors a strong option for kitchens, dining rooms, extensions and rear elevations.
Yes. Modern uPVC sliding patio doors are designed with strong security features, and House of Windows patio doors include the patented ModLok system, developed in partnership with Yale. This combines reinforcement with multi-point locking and includes four hook bolts, shoot bolts at the top and bottom of each sliding pane, anti-lift protection and optional anti-snap cylinders. These features help make uPVC patio doors a secure choice for modern homes.
uPVC sliding patio doors are designed to be energy efficient as well as practical. House of Windows patio doors use a 70mm multi-chambered frame and can achieve U-values of around 1.3 W/m²K. Internal chambers help reduce heat loss, while brush piles and compression gaskets improve weather sealing against draughts and moisture. This helps create a warmer, more comfortable home and can support better thermal performance over older patio doors.
House of Windows made to measure uPVC sliding patio doors are available in 2, 3 and 4 panel configurations. Typical size ranges are 1600mm to 2900mm wide for 2 pane doors, 2400mm to 4000mm wide for 3 pane doors and 2900mm to 4000mm wide for 4 pane doors. Typical heights range from 1900mm to 2400mm depending on the design. This gives homeowners and trade buyers plenty of flexibility when choosing sliding patio doors for extensions, garden rooms and replacement openings.
Not always. If the new uPVC sliding patio door sits directly on suitable brickwork, a cill may not be necessary. However, in many installations an 85mm stub cill, 150mm cill or 180mm cill is recommended to help direct rainwater away from the property and protect surrounding masonry. The correct cill choice depends on the threshold detail and the external ground level.
A frame extension, sometimes called an add-on, may be required if the opening has deep plaster, render, tiles or other finishes that would interfere with the door frame. These extensions increase the frame depth so the sliding patio door can fit neatly and operate correctly. Common sizes include 10mm, 20mm and 50mm, and any add-on used should be included within the final ordered dimensions.
House of Windows uPVC sliding patio doors are available in a range of popular finishes including white, cream, oak, rosewood, anthracite grey, whitegrain and Irish Oak. Dual-colour patio doors are also available, allowing a coloured exterior and a white interior. This makes it easier to match the door to both the outside of the property and the internal décor.
Yes. Made to measure uPVC sliding patio doors can be customised with a range of options including mid-rails, Georgian bars, leaded glass, textured glazing and laminated glass for added privacy or security. You can also choose from handle finishes such as white, black, gold and chrome, helping you tailor the look to suit traditional or contemporary homes.
uPVC sliding patio doors are low maintenance, but regular care will help keep them working smoothly. Keep the track clear of dirt and debris, vacuum the bottom rail when needed, and apply a silicone-based lubricant to the rollers if the door begins to feel heavy. It is also sensible to keep drainage holes clear and clean the frame and glass using mild soapy water and a soft cloth.
House of Windows supply only uPVC sliding patio doors come with a 10 year guarantee against cracking, warping and discolouration. The ModLok locking mechanism also carries a 10 year mechanical warranty, giving added peace of mind for homeowners, installers and trade customers.
