One of our traditional panelled composite external doors, the Northumberland composite back door has four glass panels (two small squares at the top and two mid sized rectangles in the middle) and two solid panels at the bottom. This door style is also known as the Carlton 4, with the Carlton referring to the six panel layout.

While known as a traditional style, with classical glass designs such as the triple glazed Zinc Art Elegance, the Northumberland composite back door also includes modern designs like the double glazed Sextet range with colourful diamonds (available in Red, Blue, Green and Black) or the triple glazed Kensington with frosted glass bordered by a clear edge. To accompany our double glazed designs, you can choose from one of our backing glass patterns, from the basic texture Cotswold to the elegant Everglade, or have simple clear backing glass or sandblast. Each backing glass pattern offers a different level of obscurity, particularly beneficial for homes requiring privacy but when you still want natural light to shine into your home.

The slab has a grained surface, like standard wooden door, which is a glass reinforced plastic (or GRP for short) skin that is weather resistant and easy to wipe clean. There are several colourful and grey tone finishes to choose from, whether you want a vibrant tone like poppy or a softer colour like dusk, a stalwart grey like anthracite or the milder silver grey. The frame comes in white as standard or can be matched to your door's finish. Similarly, the interior side of the door and frame can be made to a colour or grey finish; however most customers prefer to leave these as white.

The highly secure Northumberland composite back door has a steel reinforced pvc-u frame, and is pre fitted with a Secured By Design multi point locking system.

When it comes to ordering one of our fully fitted composite back doors, we don't take full payment upfront (orders over £3000 do require a deposit) - you pay the for the door in full after installation.
