PVC-U bi-fold door.
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.
