Description

Bi-fold door system available as standard or ModLok™ in a wide range of sizes and configurations, and with up to seven panes, depending upon the application and aperture size.

Internally beaded (external beading optional), the bi-fold system does not require trench excavation to benefit from its low threshold, making installation easier.

The patented ModLok™ technology provides a PVC-U alternative to an aluminium bi-fold door, which has been cyclic tested to more than 100 000 opening cycles and was the first to successfully pass BuildCheck's Folding Sliding Door Scheme in 2015.

Features and benefits:

  • Multi-chambered profiles to offer low U-Values.
  • Strong and secure.
  • Four wheeled bottom rolling mechanism.
  • Weather tested to 'severe' category 4600 Pa (ModLok™ only).
  • Patented exo-skeleton - no steel required (ModLok™ only).
  • Building Regulations (E&W) Approved Document M low threshold.

Accreditations:

  • Secured by Design approved (ModLok™ only).
  • PAS 24:2012 Kitemark 522037 (ModLok™ only).
  • BuildCheck Folding Sliding Scheme certified (ModLok™ only).
