Aluminium Sliding Doors

With the ever increasing demand for modern, bright, open plan spaces within new and existing homes, the ability to allow natural light to flood in has never been more crucial. Aluminium sliding doors are the ultimate solution to fill your space with natural light, due to their ability to support very large panes of glass and offer comparatively slim frame profiles, maximising the area in which light can enter.

Why Aluminium?


Aluminium is far superior to UPVC and timber in terms of strength, which allows it to support larger openings both horizontally and vertically, larger panes of glass, and offer a slimmer profile maximising the light.  With all of the advantages of this technology, you can create the ultimate uninterrupted view of your surroundings to achieve the wow factor within your home.

Completed Projects

Manchester Project

Looking to make the most of their outdoor space our clients wanted to open up an existing window to enable access to the garden and also make the most of the view to outside.

Windemere Project

Full glazing scheme supplied and installed throughout this prestigious home. To the rear of the property we supplied 3 sets of Dutemann aluminium sliding doors opening the property up to the fantastic garden and giving the rear of the property a modern edge.

Sliding Door, Chester

As part of a sympathetic renovation to a 1930 period property in Chester a large open plan kitchen / dining / living space has been created which has been given a more modern style to the rest of the property. An aluminium triple sliding door was chosen to enable our client to create a large opening that help break down the indoor/outdoor barrier ideal for entertaining in the summer months and filling the main living space with light year round.

Sliding Doors, Wirral

We supplied and installed several sets of Dutemann aluminium sliding doors throughout the home renovation in Wirral. The sliding doors create large expanses of glass making the most of the sea views throughout the year.
