Tilt and Slide Patio Doors are built much like a tilt and turn window although the main difference is that the patios lock on all four sides when you lock the handle. These doors are ultra secure as far as uPVC frames go with a minimum of 10 locking roller locks. These are especially ideal when you have a room with the patios being the only source for ventilation because you can tilt the patio door sash for ventilation and lock the handle at the same time which means you can leave the door open and you don’t have to worry about it. These can be manufactured in any colour and are fully re-enforced.
