Pilkington Insulight™  are technically advanced dual-sealed double or triple-glazed units meeting British and European standards, made in the UK.


Offering exceptional performance, Pilkington Insulight™ glazing units are preferred by many architects as they allow for maximum design flexibility and creativity. This has resulted in many of the innovative commercial buildings we see today. Pilkington Insulight™ is a technically advanced dual-sealed unit meeting British and European standards and is designed to offer a variety of performance options. A selection of dual-seal designs  can be incorporated into a wide range of glazing systems and will withstand a number of contrasting environments e.g temperature, UV light and moisture vapour permeation. The unit design has survived severe life testing trials and is fully compliant with BS EN 1279 and is therefore covered by our Pilkington Insulight™ warranty. The range comprises of a variety of popular IGU options, each custom made, using multiple panes of glass. 

Pilkington Insulight™  glazing units are available in a wide choice of glass thicknesses and glass types. They incorporate a specially designed high quality continuous rolled aluminium, steel or warm edge spacer options to separate the glass. These are available in a range of colours and varying widths as well as for specialist applications containing desiccant to keep the air or gas in the unit dry for optimum performance.

The perimeter of the IGU is hermetically sealed with a two part system made up of butyl and a silicone or polysulphide seal. The seal can withstand a wide range of temperatures and silicone has high resistance to UV rays. This means the units can be used with confidence for cladding panels, silicone structural glazing and roof glazing in addition to conventional glazing.
