Create that wow factor

We have an extensive range of products to suit any size of project. From our award-winning bifolding and sliding door systems to our innovative slide and turn, and glass moveable wall solutions - which offer new and imaginative ways to enclose and open up space.

At SUNFLEX, we have many years’ experience of overcoming the technical difficulties of producing these types of door systems. Together with our in-house training facility and the technical support that we have in place for our agents and installers, this gives us the confidence to promote SUNFLEX as the best overall package available in the market today.

Unique designs

SUNFLEX door systems offer true versatility. We have designed and perfected systems to open up corners of varying angles, and even to open around a curve, creating a unique look to your project. Extended track options on our sliding doors allow the panels to slide either into or behind a wall to achieve a 100% complete opening.

Expert installation

Any door system is only as good as the fitting team installing this. We work closely with our distributors to ensure they have the correct training to install SUNFLEX doors backed up with our own technical support team. This helps ensure the product operates at its best and optimises the lifespan of the doors.

* The referral to a recognised SUNFLEX distributor is only by way of introduction and, whilst we do hope that you choose to use their services, you are under no obligation to do so. Our distributors are experienced in fitting SUNFLEX door systems but they are an independent third party that operates completely separately from SUNFLEX UK and the terms and conditions of sale will be directly between you and this company. This company will provide you the guarantee and be responsible for any servicing work required. SUNFLEX UK therefore cannot be liable for any losses, costs, charges or expenses caused by any aspect of the contract.
