Beautiful made-to-measure bifolds

Your Osborn Glass composite bifold door will be made-to-measure, so it fits your home perfectly. You can also choose from a vast range of RAL colours, enhancing the look and atmosphere of the room, balcony or patio area – whether your property is of traditional or more contemporary design. And don’t forget, we can also manufacture and install internal composite bifold doors without a threshold.

Great light, great style – and great security

Composite bifolds still offer great security. Our doors feature:

  • bifolds with master sash fitted with multi-point lock includes hooks, dead-bolts and shoot-bolts
  • lever/lever handle including key-operated 3-Star cylinder (5 keys)
  • stainless steel anti-jemmy pins fitted inside top roller track
  • shoot-bolt locks (top and bottom) operated by an internal D-handle lever


Apeer’s doors are chosen by homeowners who appreciate exceptional craftsmanship, timeless elegance and built-to-last quality. They quickly discover that all this good stuff means plenty more.

All their doors come with a 10-year warranty, are secured and a-rated by design. We’ve been partnered with Apeer for (X) years now and can vouch for the incredible craftsmanship and results they’ve ensured for personal and business clients alike.
