The outstanding feature that makes these uPVC patio doors so popular, is the grey substrate option. With a entirely grey frame instead of just a surface foil, there’s no hint of the white uPVC core, even when the door is opened. This allows homeowners to enjoy the look of aluminium without choosing the more expensive premium aluminium glazing option. Because patio doors are open for extended periods of time on warm days, it also makes for much cleaner lines by doing away with the exposed white sash core.

Our uPVC patio doors achieve PAS24 standards, which means homeowners can meet Document Q - the newest security regulations for uPVC patio doors and other similar renovations.
