Sunflex vs Schüco bi-fold doors: Which is best?

Sunflex vs schuco aluminium bifolding doors

Here at Chase Windows, we offer an almost unlimited range of bifold doors. They make the ideal connection between your inside and outside living spaces. With a unique folding and stacking design, you won’t take up any of your valuable space inside or out. They look impressive and give you an innovative alternative to standard sliding patio doors. Let’s take a look at the two of the most popular brands of aluminium bifold doors we offer: Sunflex and Schüco.

The perfect door material

Aluminium is a fantastic material for a door. Exceptionally strong and naturally insulating, it provides protection for your home against the elements. Aluminium has the ultra-modern look that many find desirable for their homes. Due to being stronger than other materials, the frames can be slimmer and hold more glass. This floods your home with light and allows you greater views across your garden and surrounding countryside.

Efficiency and performance

Schüco bi-folding doors are thermally broken for a comfortable temperature all year round. This ensures your home uses energy efficiently. As well as keeping you warm, this will save you money on your heating bills and is good for the environment. Sunflex aluminium bi-fold doors have exceptionally low u-values to offer your home as much protection against draughts as possible. With double glazing 1.4 can be achieved and 0.9 is possible with triple. Both doors offer superb weatherproofing, so rain and wind are no match.

Truly impressive doors that take design seriously

Both doors allow for complete flexibility as can slide either left or right and will easily fold and stack inwards or outwards. This gives you more space in your home. The beauty of bi-fold doors is that when fully opened they can make your home feel open-plan and let your garden blend with your home. This ensures you make the most of your outside space and makes your home a great place for entertaining. Schüco’s beautifully designed doors can be up to 3m high and 1.2m wide which will fill your home with as much light as possible. You can have a flush threshold to ensure that your door is easily accessible for everyone. This also makes moving furniture around much easier.

Sunflex bi-fold doors can hold glazing units up to 48mm thick. With slim frames of only 115mm, you can enjoy greater views and more light. These can be made up to 3.5 m high and 1.2m wide so you could create a fully glazed wall if you wish. Both doors can be made in any RAL colour to create any style you like in your home. Although they are a modern door, this doesn’t mean they can’t be made to suit older homes too. With authentic heritage colours and woodgrain effects, they can perfectly suit any home.

Security is always a priority

Schüco doors are extremely burglar resistant and smart automatic opening is available to bring your home into the 21st century. Secured by Design accreditation is available with Sunflex bi-fold doors. This police initiative ensures high levels of intrusion resistance from your windows and doors. With all our doors, multipoint locks come as standard to give you peace of mind that your home is protected.
