Bifold Doors

Ergonomic, beautiful uPVC bi-fold doors

Our uPVC bi-fold doors are the ultimate home improvement product for homeowners who want to create truly open, modern living spaces. Perfect for larger properties, bi-fold doors are able to create large apertures which, when opened, seamlessly join the indoor and outdoor areas of your property. uPVC bi-fold doors from Alpine also feature especially slim sightlines so that when they are closed, you maintain a stunning view of your garden or patio area, letting in huge amounts of daylight – allowing you to enjoy the outdoors from within your home, even during the colder months of the year.

With a huge range of panel configurations, Alpine’s uPVC bi-folds are also highly practical, featuring smooth running tracks, handles which fold back for discreet aesthetics, weather seals for efficiency, and a design which meets Secured by Design standards.

Aluminium bi-fold doors for durability and aesthetics

With all the benefits of our uPVC bi-folding door range – facilitating modern, open plan living with efficient and secure designs – aluminium bi-folds from Alpine offer a number of unique characteristics. Because of aluminium’s comparatively greater strength, they are able to offer even slimmer sightlines than their uPVC counterparts, featuring larger areas of glass for maximum levels of daylight and potential solar gain. Our aluminium bi-fold doors are also highly weather resistant, and are extremely durable and resistant to the effects of rusting or expansion and contraction due to adverse weather conditions. This ensures that your bi-folding doors operate without fault, giving you the ultimate levels of performance time and time again.

Aluminium bi-fold doors from Alpine Glass are also available in an extensive array of RAL internal and external colours, meaning that they can be supplied to match your home’s existing colour scheme and interior decor.
