Patio doors welcome the outside in

Sliding glass doors effortlessly glide along a streamlined track, whereas elegant French doors feature a set of two glazed panels that typically open outwards onto your patio space.

Our sliding patio doors are available with 2, 3, or 4 glazed panels and our French doors can be designed with illuminating side panels and top lights, should your project require extra illumination. So, whether it's a classic 2-panel white patio slider, a minimalist set of French doors in edgy Anthracite Grey, or something a bit different, we’re confident we can tailor the perfect patio door replacement to enhance your property’s unique character.

What is the difference between a sliding door and a french door?

They are both forms of patio doors however the main difference is the way that they open. French doors are double doors that rely on hinges to fully swing open, while sliding patio doors slide on a track built along the wall. Each one has it's own merits depending on the availability in the room.

Are sliding patio doors worth it?

Sliding patio doors are an excellent choice for flooding your room with natural light as they are predominately made up of panes of glass. Consequently, they also allow wide, panoramic uninterrupted views of your garden.

    Outstanding Service

    We had many issues trying to locate a company to replace our conservatory roof however, this company was recommended to us by a friend of a friend and we couldn’t be happier. It was really refreshing to have a company not place any pressure for a sale; always available to answer any queries; worked incredibly quick and professionally throughout with a friendly manner. We are so impressed with the service received, that we have now booked them again in May to have our windows replaced.

    ‘Double Glazing Direct’ were brilliant.

    They were extremely polite and professional. Before they started the work on the day of installation, taking out the existing windows, they prepared the area with dust sheets and special protective flooring on our wood floor and stairs. The fitters were skilled knowledgeable and focussed. There was no mess made during the installation. The quality of the product and installation was excellent. I love my windows and I will always recommend ‘Double Glazing Direct’.
