The SG12 system comes in two options Semi-Frameless and Fully Frameless. The Fully Frameless does not have a handrail on top and uses 21.5mm laminated and toughened glass. Installation of the fully frameless requires more time for glass alignment and positioning as there is no handrail on top to hold the glasses straight. The SG12 Fully Frameless system allows for 100% uninterrupted views without even a handrail line. There are no limitations of lengths or sizes and requires no posts or handrails at all.

Frameless glass balustrades for balconies, a decking area or mezzanine create an almost invisible barrier between the viewer and the view.

The pictures here [pictures] of some of our projects using these top-of-the-range glass balustrades tell the story better than any superlatives or poetry could hope to do.

Relying on the strength of the glass that is secured to a sturdy base rail, without any vertical supports or even a handrail, our frameless glass balustrades use thicker and heavier super-strong laminated and toughened safety glass. This naturally makes this the most expensive of our glass balustrading options.

But what you get is the considerable aesthetic benefit of virtually limitless expanses of pure uninterrupted glass without supports, clamps or corner posts - or even the line of a handrail.

Looking outwards, this means views as uninterrupted as views are likely to get until someone invents the invisible force field. And, within, it means more light, more sense of space and a feature that will blend with virtually any architectural or decorative style or design.

Glass is a material that will last for all intents and purposes almost forever. The safety glass of our frameless glass balustrades includes two panels that are both toughened and bonded together by a plastic safety interlayer. The reason this interlayer is used is so that if one of the glasses should break the other will remain in position. This is a relatively new addition to BS 6180, added in 2011, which allows the omission of a handrail in these cases.

As a recommended but optional extra you can choose to have the BalcoNano coating applied to the glass. The added benefit of this is that it is virtually self-cleaning so you don’t have to clean it very often either – and when you do the job is an easy one.

The below is a concise summary of how to install the Balcony SG12 Fully-Frameless System.

  1. Install the base track in the position you require, fixing it firmly to the structure.
  2. Make sure the rail is closed off on the edges and seal any gaps on the end or where there are joins in the base track. (the resin that holds the glass is liquid and you want to ensure it does not have anywhere to leak out of the base track)
  3. Identify the glass panels and where they each go.
  4. Place two orange glass packers for each panel.
  5. One at a time place glasses in position
  6. The glasses will usually be polished on 3 sides and the unpolished side will be meant for inside the base track. Make sure all the polished edges are the ones left showing.
  7. Use small glass packers or wedges to hold the glass vertical against the base rail.
  8. Using two small wood pieces clamp one glass to the previous to create a straight line - you will need to make sure of the glass height level is straight.
  9. When all glasses are in position and lined up, check glass alignment along the length and on top of the glasses.
  10. Making sure glass is held only via wedges or packers at the bottom release the wood clamps at the top and see that glasses are aligned still. Adjust as needed so they are 100% straight before resin. This will ensure they remain straight after resin and that they are not in any stress position and go out of alignment once the top clamping removed.
  11. Using the glass resin provided mix the two components and carefully, and slowly pour the resin into the base track. Please note that the resin is self-levelling. Reaction time is dependent on temperature and humidity; the warmer it is the faster it will cure. The resin has quite a thick viscosity and you should plan your work so you can complete pouring areas or runs continuously before it cures. (If doing sloped runs a different resin or material needs to be used and not a liquid one)
  12. Let the resin cure for at least 24-48 hours before any contact with the balustrade. MAKE SURE NO ACCESS OR PERSONS ARE ALLOWED TO MOVE THE GLASSES WHILE NOT CURED.
