Patio Doors

UPVC & ALUMINIUM SLIDING PATIO DOORS

Sliding Patio Doors are a perfect choice for any home.

Our sliding patio doors are opulent, highly energy-efficient. Our doors are double glazed with high-security locking systems as standard. The sliding panels are easy to open and close and the interlocking door leaves prevent draughts. Not only are the door systems aesthetic appealing, but they also have less frame and more glass than Bi-fold or French doors.

Our uPVC patio door range is easy to maintain, will never rot, rust or flake, and come in a large range of RAL colours. Aluminium patio doors come in two, three or four-panel options like our Triple-track sliders and add a contemporary feel to any home improvements project. The aluminium frame has a slimmer profile, has a selection of handle colours and modern frame colours to choose from.

Key Features

  • Less Frame
  • More Glass
