Beautiful to look at
The Sheerline’s slim sightlines and large glass panels make it a genuinely beautiful addition to any home. It looks as good from the garden as it does from the inside.
Stunning Sheerline Aluminium Bi-Fold Doors.
Sheerline is a British-made aluminium bi-fold door range that we’ve been fitting across Surrey for a number of years, and it’s a product we genuinely rate. Designed and manufactured in the UK, it combines exceptionally slim sightlines with robust, high-quality components that are built to perform year after year.
Whether you’re opening up a kitchen into the garden or transforming an extension into something special, the Sheerline is a door that does the job beautifully and keeps on doing it.
Sheerline Bi-Folds Are Doors Built Around the Details
The Sheerline’s concertina folding style means the panels stack neatly to one side when open, giving you the fullest possible opening with nothing in the way. Available in up to 7 panels and a range of configurations, it works just as well in a smaller opening as it does across a wide rear extension.
The sightlines are exceptionally slim, which means more glass and less frame wherever you look. Every element has been engineered with care — one-piece stainless steel tracks keep the panels rolling smoothly, 120kg rated hinges keep everything aligned, and slim internal handles keep the whole thing looking clean and uncluttered. It’s the kind of door where the quality is obvious the moment you use it.
- They have an incredibly versatile design
