Aluminium inline-sliding patio doors

Custom built for a perfect fit

An inline sliding door is the best option for being able to access your garden, patio or balcony with ease.

They are made to measure with different door panel configurations that are all easy slide.

The amount of glass is maximised with a sliding door, giving extended visibility, and the effortless sliding operation does not encroach on either side.

You can also have the door open as much or as little as you desire without fear of them being blown shut in windy conditions.

Case Study

Berkley Heights

Installation in the lovelyboutique town of Frome, Somerset, for Jenkins Developments

This project was dominated by the offset gable glazed façade to the rear elevation. A contemporary design that made the most of simple slim Smarts Alitherm 300 windows designed to maximise all glass areas and provide ample light to the internal aspects. The frontage was further enhanced with a Smarts Designer Doors all powder coated in a Sensations Antique Frey finish. The Rear Kitchen Diner is flooded with light from the two storey glazing, the bottom of which is constructed from a Triple Track 6 Pane Smarts Visoglide Plus Sliding Patio Door, with super slim meeting stiles this provides 6 large glazed areas when closed and with the 4 sliding sections creates a fantastic clear opening when all the doors are fully opened. Careful attention was paid to lining everything through with the above fixed panes and all the cladding were matched to produce a single gable infill from outside.

Case Study

The Croft

Installation the village of Crockerton, on the edge of the Longleat Estate, Wiltshire

Its all about the wow factor. Triple Track 6 pane sliding doors that achieve a clear opening of 8 metres, coupled with slim meeting stiles. These Visoglide Plus doors give the best of both worlds large glass with miniomal uprights when closed and a huge opening when all 4 doors are fully opened. Special attention was paid to the threshold detail where we worked with the developer to achieve a flush floor from inside to outside. All finished in Sensations Platinum Grey.
