The Crystal range of thermally efficient PVC-U/aluminium hybrid (WarmCore) residential doors are available in a traditional French door and a single door style, ideal for keeping a consistent look with the bi-fold door system.
Built to the same exacting standards as the larger doors, this range gives you all the benefits of warm aluminium, at a more modest size.
