Lincoln sliding folding doors

Carefully manufactured by us in Norfolk, our Lincoln folding door system brings together many desirable features of bifold doors!

At just 120mm the slim sightlines are so unobtrusive they maximise the glass area and minimise obstructions to your view. Whilst being slim, the doors are also strong, secure and durable, and so easy to open and close!

Designed with the desirable aesthetics and insulation requirements of a private home, yet still with outstanding durability & reliability required in commercial applications. High security, with minimal maintenance and fully guaranteed, they are a favourite.
