There are numerous structural glass systems offered by various suppliers that open up vast possibilities for architects, allowing them to create a complete glass envelope for buildings with frameless façades on any plane.

Pilkington Planar™ is used by architects to create expansive flush glass surfaces. The system utilises stainless steel fittings housed in countersunk holes to fix glass to its structure, making it more discreet while maximising visibility.

A quick guide to some of the Standards & Building Regulations used in construction that have implications for the choice of glass

* g-value depends on which thermal insulation glass is selected as inner pane ** g-value depends on which thermal insulation glass is selected as inner pane (all based on 4 mm thickness) For higher g-values please refer to our Thermal Insulation glass product range; For thicknesses other than above calculate using Pilkington Spectrum

Pilkington OptiView™ is a range of glass with an anti-reflective coating(s) to reduce visible light reflectance and to allow more light to pass through. The range is suitable for monolithic, laminated, and toughened applications and can also be glazed as part of an insulated glass unit build-up where required.

Glass in its annealed form, framed and in tact is not an immediate threat but when it is broken the long shards turn into effective cutting devices with sharp edges and momentum. Fortunately glass can be modified to change these properties and reduce the risk of injury dramatically.

Improves the energy efficiency of domestic or commercial buildings whilst enabling the extensive use of glass and the benefit of passive solar gain.

The strength of glass is determined by putting the glass under stress until it breaks. The surface strength is measured using a ring and the edge strength by 4 point bending. The test is repeated to derive a distribution for the break strength.

Solar control glass either reflects energy or absorbs it to reradiate the heat outwards. By its nature it gets hotter that clear glass and glass that is designed for thermal efficiency alone like Pilkington K Glass™ and Pilkington Optitherm SN™.
