Improve your lifestyle and the value of your home

Bifold doors open up your home to nature and make it easy to have the outdoors as a part of your everyday life. Not only are they great if you’re wanting to open up your home, but in many cases, they increase the value of your property.

uPVC bifold doors are a great option for those of you wanting to do all these things, and stay cost-conscious. They’re also great if you like minimal maintenance (which we don’t blame you for). You can be sure that there are a colour and style that will match your requirements and your home, and we’ll help you find it.

Let the outdoors in, but only when you choose to

Choosing bifolds doesn’t mean less security. Our doors include:

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

All doors come with double-glazed toughened glass as standard.
