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.

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.

Here are John Knight Glass we are specialists in Aluminium sliding doors and are delighted to be the chosen supplier within the North West for Panoramah, who offer the largest sliding doors available in the UK.  As with all of our aluminium products, our aluminium doors are available in a wide range of RAL colours offering you the ultimate flexibility in seamlessly adding sliding doors to your exiting configuration.

Our aluminium doors can be supplied fitted with a wide range of glazing options, from single glazing for interior use right through to triple glazing capable of achieving Passive Haus standard.  We also have specific glazing options to achieve sound proofing, solar gain and excellent U-Values.

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.
