Introduction to uPVC sliding patio doors

Bringing the outdoors in while saving inside space, uPVC sliding patio doors offer the best of both worlds. With large views and easy access to gardens, decks, and patios, these functional doors add light with a great indoor-outdoor flow.

This comprehensive guide will show the details of shopping for, installing, and living with uPVC sliding patio doors. Let’s see how upgrading your french patio doors to sliding doors can enhance aesthetics, maximise natural light, and improve your quality of life.

Understanding Sliding Patio Doors

Sliding patio doors consist of two or more rectangular door panels that slide horizontally along an overhead track system. This space-saving design eliminates the swing radius of hinged doors, making them ideal options for tight spaces.

While they function similarly, sliding patio doors differ from sliding glass doors. Patio doors feature durable uPVC or composite construction that withstands weathering better than delicate glass. They deliver stunning views while providing insulation, durability, and security.

Types of Sliding Patio Doors

Homeowners can choose from two main sliding patio door styles:

  • Traditional – Features two panels, with one sliding past the fixed pane using a simple pulley mechanism.
  • Contemporary – Offers the sleek look of expansive uninterrupted glass with two, three, or even four panels smoothly gliding and stacking to the side using a state-of-the-art roller system.

When selecting doors, consider the number of panels, internal grilles, and colour options to find your perfect style.

Factors to Consider When Choosing Doors

Keep the following aspects in mind when shopping for sliding patio doors:

  • Size – Measure your rough opening carefully for an accurate fit. Factor in desired clearances.
  • Material – uPVC and aluminium are durable, energy-efficient options that can mimic wood’s appearance.
  • Energy Efficiency – Look for A STAR rated models and thermally efficient with double glazing.
  • Hardware – Seek quality rollers/guides and durable, weather-resistant finishes.
  • Safety – Tempered, laminated glass and multi-point locks provide security.
  • With attention to these details, you’re sure to select high-performing, visually stunning sliding doors.

The Cost of Sliding Patio Doors

Pricing for uPVC sliding patio doors starts with simple two-panel kits. More complex styles with multiple panels and custom details can cost far more to be installed. Brand, size, materials, and options impact overall expense. For instance, Pella’s Architect Series patio doors cost more due to unparalleled craftsmanship and technology built to last a lifetime.

Installation of Sliding Patio Doors

Installing sliding patio doors is best left to professionals, as precise alignment and flashing is crucial to performance.

For DIYers, follow manufacturer instructions closely and have an assistant. Thoroughly waterproof around the perimeter and test operation multiple times to ensure smooth sliding function.

Maintaining Your Sliding Patio Doors

Regular maintenance keeps sliding doors operating like new:

  • Inspect rollers and tracks yearly, cleaning debris and replacing damaged parts so doors glide easily.
  • Keep seals and weatherstripping around the frame in good condition to prevent air and water infiltration.
  • Clean glass as needed with vinegar and water to prevent mineral buildup.
  • Check for leaks, cracks, or cloudiness in glass which require immediate repair.
  • With a little maintenance and proper care, your sliding glass patio doors will provide enjoyment for years on end.

Security Features

uPVC, timber and aluminium sliding patio doors used to be the weak spot on a home and were a welcome sight to burglars. Not anymore. Designs for all including aluminium patio doors, have evolved and new technology has made them one of the most secure doors on the market.

Each of our aluminium, uPVC and timber sliding patio doors are constructed from systems with Secured By Design status, meaning not only have they undergone rigorous industry testing to qualify for this official police initiative, but their modern designs also meet the superior quality standards expected by the scheme.

Our sliding patio doors are fitted with a multitude of security features to protect your home, including the following:

  • PAS 24:2012 security tested – a method to test the security performance of new doors, as required by the British Standards Institute.
  • Anti-jacking technology – this prevents the glass panes of the sliding door from being levered open.
  • Anti-lift blocks – it’s fitted in the rails to stop the sliding door being lifted from the outside and allowing unwanted access.
  • Hook latches – this restricts the opening of the sliding door, preventing intruders from gaining access into your home.
  • Multipoint locking – this system locks at several points, providing superior protection against forced entry into the keyhole.
  • Toughened glass – up to five times stronger than normal glazing panes, this is an additional type of safety glass that adds significant strength to your home security.
