One of the most popular back door options, bi-folding doors are a wonderful solution for improving the view of your garden while remaining energy efficient at the same time. With better thermal insulation than sliding doors, they help to keep your house warm and filled with natural light, often adding value to your property.
Customised to specifically suit your property, our team of expert door fitters can help you pick every aspect of your stylish new bi-folding doors. Choose everything from the configuration of the doors, handles, accessories and colour in order to create the perfect addition to your home.
Packed with energy efficient technology including Planitherm Total Low E glass, warm edge spacer bar technology and argon gas filled as standard, our bi-folding doors will help to keep your house warm and cosy even during the winter months. We can even offer a triple glazed option if so desired.
Built using aluminium and finished with a powder coated paint, our stylish and practical bi-folding doors are guaranteed to last without fading or peeling over time. We offer a fully comprehensive 10 year guarantee, backed by insurance and covering labour and materials, so you can be sure that your bi-fold doors will stand the test of time.
