Our Posiglaze frameless glass balustrade system consists of everything you need for a frameless glass balustrade, excluding the glass (ordered from us, but separately).
- 3m length of predrilled aluminium U-channel (base or side fixed)
- Top seal strip/beading, 2 off @ 3m
- Clamp kit with clamps, clamp bars, bolts and gasket, to suit your glass thickness (12-21.5mm)
- Spanner (10mm, to suit clamp kit)
We supply the aluminium U-channel predrilled at 200mm centres. It has a brushed stainless steel effect finish.
With its honeycomb design, the U-channel is lightweight (25kg per 3m), but still achieves up to 1.5kN loading and complies with BS 6180. It is fixed and adjusted using the clamp kits and spanner. With the top seal strip/beading, overall height is 120mm and width is 72mm.
The most important thing to recognise is that if no top rail is in place then toughened laminated glass must be used.
With top rail
For an internal balustrade with no fall factor, 12mm glass is suitable.
For internal use, with a fall factor and with a top rail 15mm toughened is suitable (0.74kN loading).
Where a 1.5kN loading is required, 19mm toughened glass should be use.
No top rail
For an internal balustrade with no top rail, 17.5mm toughened laminated glass should be used.
An external balustrade should use 21.5mm toughened laminated.
