Application

Suitable for new build and refurbishment projects.

Description

High performance, made to measure timber folding and stacking doors for both new build and refurbishment projects.


Features and benefits:

  • Can create large glazed areas, allowing more natural light to enter a room.
  • Can be configured to suit a wide range of apertures, maximising space and ‘bringing the outside in’.
  • Designed in a variety of styles, from plain glazed to more traditional glazing bar and leaded designs.
  • Bi-fold doors open outwards and consist of various opening configurations of door leaves, supported at the head. 
  • Manufactured to precise measurements, enabling them to fold and slide seamlessly.
  • Treated with a three-coat, spray-applied, microporous paint system prior to delivery.
  • Complementing and contrasting colour palette.
