Many homeowners have a preconceived idea that patio doors are easier to break into because of the large area of glass. This tends to be unfounded as invariably intruders don’t smash glass (modern double glazing is actually very hard to smash anyway) but would instead aim for the locking mechanisms. Everest uses a range of tough and comprehensive mechanisms that make the doors very hard to access without a key.

Standard patio doors are 2.1m high and come in 2,3 and 4 panels. However, there are many options to consider when choosing patio doors. Most of the time the size of the opening will denote the number of panels. A standard panel width will be around 1m.

With such a large amount of glass there is a tendency that they will be less efficient than having a smaller standard window built into the wall. However, our patio doors are argon filled and use energy-efficient glass that harvests heat from the sun reducing the impact of the large glass surface area.

Both types of doors offer their own benefits. Being able to open up the whole of the entrance aperture with Bi-fold doors are great on a summer's day and can add real impact to a room. However, bi-fold doors do tend to have more frame. Sliding patio doors only open up 50% of the door entrance but have less frame so allow for more light.

Everest offers a range of 5 colours for uPVC and 5 for aluminium. In addition, on our uPVC frames, you can choose some of the colours to have white on the inside and colour on the outside. We have selected our colour range to enable homeowners to be able to match their new doors to their window designs.
