Bi-folding doors are one of the most transformative home improvements you can make — and our aluminium bi-folding doors are among the most requested products we install across St Austell and the surrounding area. Folding back almost completely in a concertina action, bi-folds open your home to the garden in a way that no other door system can match — creating a seamless connection between inside and outside, flooding your room with natural light and genuinely transforming the way you use your living space. Available in 2 to 6+ panels, with traffic door options, in any RAL colour and with slim thermally broken aluminium frames that maximise the glazed area. Every bi-folding door we supply is Secured by Design certified and backed by our 10-year insurance-backed guarantee.
Our aluminium bi-folding doors are available in 2, 3 and 4 panel configurations — folding to either the left, right or both sides depending on your preference and the configuration of your opening. Most popular for kitchen extensions, rear elevations and garden rooms across St Austell and nearby.
For wider openings — our 5, 6 and larger panel bi-folding door systems can span openings of 6 metres or more, completely opening your living space to the garden. Available with traffic door panels for everyday pedestrian access without needing to fold the whole system.
A traffic door is a designated single panel within the bi-fold system that can be opened independently as a standard door for everyday use. This means you don't need to fold the entire system every time you want to step outside — a practical and popular option for busy family homes across St Austell.
All our bi-folding doors feature thermally broken aluminium frames — separating inner and outer aluminium with a polyamide thermal break to prevent heat loss and cold bridging. Combined with A-rated double glazed units, our bi-folds deliver year-round thermal comfort without sacrificing their ultra-slim sightlines.
Bi-folding doors fold back in a concertina to open the full width of the aperture, creating a completely open connection between inside and outside. Sliding patio doors glide along a track and always have at least one fixed panel. Bi-folds are better for maximum openness; sliding doors are better for smaller spaces.
Our bi-folding doors are available from 2 panels up to 6 or more, depending on the width of your opening. We will recommend the most appropriate configuration during your free home survey based on the size and layout of your opening.
Yes. All our bi-folding doors meet Secured by Design standards and feature multi-point locking systems, anti-lift mechanisms and toughened safety glass as standard. The aluminium frames are inherently strong and provide excellent resistance to forced entry.
Aluminium bi-folding doors typically start from around £2,500 for a three-panel unit fully supplied and installed. Prices vary depending on the number of panels, size of the opening, colour and specification. Contact us for a free no-obligation quote.
