Profile description

  1. Door frame: Thanks to its 70 mm frame depth and three hinges connecting the frame to the sash, this uPVC back door is particularly sturdy and durable.
  2. Door sash: High-quality seals surrounding the sash provide effective water resistance and ensure good thermal insulation.
  3. Steel reinforcement: The steel reinforcement located in the profile’s chambers means that the sash and frame are very stable and retain their shape, ensuring secure and correct closure.
  4. Glass insert: Decorative glass inserts adorn the door panel.
  5. Door panel: The door panel, featuring steel decoration, is 24 mm thick and made from uPVC with foam insulation at its core.
  6. Threshold: 20 mm in height, the durable aluminium threshold protects the door from daily wear.

The modern Preston back door

The Preston back door effortlessly adds character and style to back and side entrances with its stainless-steel decoration and square glass inserts.

A wide range of colour finishes are available to choose from, including classic white and anthracite as well as wood-replica decors like birch and golden oak.

In terms of interiors, the door’s decorative elements, such as the double-glazed inserts also leave their mark – light shines through to create a warm, welcoming atmosphere while privacy is maintained due to the ornamental surface finish of the glass.

Beyond design, a good back door should also provide excellent functional performance, especially as it usually externally faces the elements. uPVC, with its sleek modern surface, is an ideal door material here given its low-maintenance and durable weather-resistance.

Further features, such as the Preston door’s built-in steel reinforcement then sturdy the profile further and ensure that the frame and panel won’t deform and so will continue to fit with each other for years to come. As the door’s threshold faces the most daily wear and tear, this is also covered with protective aluminium to guarantee a long product life.

Security is another important area where back doors need to perform well. For enhanced break-in protection, the Preston back door therefore features a three-point Siegenia locking system, along with further quality fittings, which secure the door panel firmly to the frame.
