About Us

Bi-folding Doors: brought to the UK market first by Sunfold Systems!

Established in 1989, Sunfold Systems has carved itself a unique position in the door and window market through its contemporary and traditional product range, and as the first supplier to bring bi-folding doors to the UK, it has over the years developed a distinct reputation for its levels of quality, prestige and diversity as a supplier and installer.

Each project is unique and equally as important so it’s vital that we’re there with you every step of the way. We will therefore take the project from initial contact dealing with design, pricing and site surveys through to in-depth CAD development, manufacture, delivery and installation; we even conduct a completion survey to ensure the project is finished to not only your exacting standards but also our own. In fact, last year alone over 95% of our customers said that they wouldn’t hesitate to recommend us to friends, families and colleagues. 

Using innovative German engineering, all our products come with a five to 10 year guarantee (dependent on the product) and are built to last and stand the test of time. With this in mind, the environment has also been seriously taken into account both in materials sourced, production methods and installation. This is especially important nowadays when we are all conscious of energy costs and ensuring that there is little energy wastage as a result, so all our bi-folding doors and external doors and windows are designed to ensure limited heat and energy loss across the entire range.

If you’re looking for bi-folding doors, sliding doors, stacking door systems, front doors, fire doors, windows or even glazed roofing, contact us today direct on 01953 423 423 for your no obligation quote or find out where your local dealer is by visiting our dealer section.
