Composite Doors

With a wide range of modern doors to choose from, your new uPVC door can add value to your property, improve character and style and save you money with lower heating bills.

Entry and exterior doors should keep the heat in and the cold out. They also need to be able to stand up to being exposed to all kinds of different weather conditions – extreme heat, extreme cold, sunshine, rain, snow and even storms. Our uPVC doors will protect your home from all the elements.


Solid, full panel doors are ideal for maximum privacy. Best for entrances that open on to pavements or shared access areas. Semi or part glazed doors allow more light into entrance areas while still offering privacy for front doors. You can let enough light in and protect your privacy at the same time by using obscure or frosted glass.

If you have a dark hallway, choosing a full glazed front door can help brighten your home. For rear or side doors – that open on to private or secluded areas – a style with fewer panels and a generous amount of glazing will let in the maximum amount of light.

Sliding patio doors or French patio doors made by A&J allow you to easily move from inside your home to outside, making your garden, patio or deck a part of your everyday life.

Why compromise when you can get both beauty and brawn – great looks, optimum security and superb performance rolled in to one door

Weather and maintenance

uPVC doors have a higher resistance to weathering than wood and require less maintenance. They just need a regular wipe over with a damp cloth when they get dirty.

Simply lubricate the uPVC door locking system and hinges every six months to ensure they outlast their guarantee. WD40 or a silicone spray is suitable in this regard.

Why choose A&J doors?
