Sliding Folding Doors – Lincoln

You will be impressed by the slim sightlines and the sturdy feel of our Lincoln sliding folding doors! Expertly manufactured by us in Norfolk, our bespoke bifolds bring together many different desirable features of sliding folding doors for you!

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

Large panels up to 1200mm wide can be manufactured, so that you can reduce the number of panels in a given opening width. This is generally our customers preferred visual option and also helps to keep the price down – always a winner! As we manufacture in house and keep aluminium profiles in stock we can usually offer very fast turnaround times on standard ocloured frames, with a typical lead time of approximately 2-3 weeks.

Designed with the desirable aesthetics and insulation requirements of a private home, yet still with the outstanding durability & the reliability required in commercial applications, the Lincoln has high security standards, with minimal maintenance and all our bifolds are fully guaranteed by us with the added protection of an independent insurance backed guarantee through IWA. Our sliding folding doors are a definite favourite with customers.
