What are bifold doors?

Here at Chase Windows, we offer an almost unlimited range of the best bifold doors. When open, the panels are neatly arranged together and take up minimal space. When bifold doors are closed, the panels are organised perfectly along the rail, dividing up your living space. Why should you choose bifold doors? They make the ideal connection between your inside and outside living areas. 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 bifold doors.

The perfect door material for the best bifold doors

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. Read more here about why we love Sunflex bifold doors! With double glazing1.4 can be achieved and 0.9 is possible with triple. Both doors offer superb weatherproofing, so rain and wind are no match.
