BENGglas is a perfect product for the renovation market. Unlike traditional insulating glass, vacuum glass is extremely thin (from 6.3 mm) and will therefor always fit into existing window frames. Replacing a window frame is therefore not necessary.

With its low U-value, BENGglas also contributes to the sustainability of existing homes and buildings. With the replacement of single glass to tempered vacuum glass, the waste of energy of a home will be significantly reduced.

New constructions

It is still the case that glass is the weak link in the thermal insulation of building. For example, traditional HR++ glass has an U-value of 1.1 and triple glazing has an U-value of 0.7. An insulation value of 0.4 is there for unique and brings ‘energy neutral buildings’ a step closer.

Nowadays, noise reduction is also increasingly part of modern living and working. This wish can be realized immediately by using BENG glass (dB>=36).

With these values, all contemporary standards of durability and comfort are met.

With its product range, BENGglas focuses on non-residential construction as well as residential construction.
