Single Glazed Doors Technical Specification

Our single glazed doors are perfect for internal use, balcony enclosures, commercial partitions and room dividers. Using high quality components and safety glass, they come with high performance and long-service life. 

Single glazed doors don’t rely on the more stringent thermal and other specifications of our double glazed exterior patio doors.  However, we design and manufacture your doors to give the best possible user experience wherever you choose to have them in your home.

Design Specification

On Single glazed units, all glass used is 10mm or 12mm toughened with BS Kite mark and is polished on long edges. Schlegel is fitted between doors or you can have a clear PVC seals, which give a complete weatherproof seal. The tracks and profiles are made of aluminium produced in the United Kingdom.

The profiles on doors are connected to the tracks by means of a flag, including spacers which slide inside along the tracks. The tracks contains top and bottom turning mechanisms which automatically tell us where the doors are to open. Doors can only be opened at gates, which are 6mm by 5mm, which makes them extremely secure.

The door locking mechanism is a stainless steel (satin or polished) privacy lock or a poppit which is opened by pulling a clear acrylic bar towards you.

The framework is produced from powder coated aluminium, manufactured in the UK and can be supplied in any RAL colour you specify. The sides are sealed with a grey PVC plastic.

How our single glazed doors slide and fold. 

All doors slide on PTFE (Pure Teflon), and all the weight is at the bottom, it doesn’t hang, there are no wheels, and it slides by kinetic energy. You can only open the doors when they are in the correct position at the gate, which are in the first door opening only and are 6mm wide x 5mm deep. There is a turning mechanism in the top and bottom track, on which the flags fit into. This allows you to open each door as it automatically touches and locks into position. Once open the doors stack neatly side by side with just 5mm between each door, with the profile being 40mm wide. Doors can stack all one side or both sides any combination.

Very Pleased with the Freedom the Installation affords

We are very pleased with the freedom the installation affords us with easy access from lounge to dining room. Aesthetically the glass curtain installation is very pleasing. All appears well but we must point out the bottom bar is not firmly fixed in the channel in the floor & moves if one stands upon it.
