FAQs

Which is better, sliding doors or bifold doors?

Timber bifold doors fold back against themselves in a concertina style and will stack against one side, either inside or outside your home. These doors open fully and create the biggest opening to the outside.
Timber sliding door panels sit behind one another, so they don’t create a fully unobstructed view as one panel will always be visible. But if you’re short of space within your home, sliding doors are the best option as they don’t take up valuable space.

Do you offer a guarantee on timber bifold doors and sliding doors?

We manufacture fully-certified and sustainable bespoke timber windows and doors, proven through rigorous testing. Our timber bifold and sliding doors offer a 30-year guarantee on timber. The performance of timber is subject to the environment, structural detail, and maintenance of the surface coating. For more information about our guarantees, visit our warranty page.

Do you offer any other patio doors?

Yes, we do! In addition to timber sliding and bifold doors, we have timber French doors to connect you to the outdoors.
