Preservation of a house

In order to make this house more sustainable, BENGglas provided the entire facade with tempered vacuum glass. As a result the U-value of the glass has been reduced significantly from U=2.8 to no less than U=0.4!

When renovating windows in a house, there is often a limited installation depth in the window frames available. As vacuum glass is very thin (from 6.3mm), it always fits into the existing frames; i.e. the window frames do not have to be replaced.


BENGglas is a perfect product for the renovation market. Unlike traditional insulating glass, vacuum glass is extremely thin (from 6.3mm) and will therefore 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 in a home will be significantly reduced.

New Constructions

It is still the case that glass is the weak link in the thermal insulation of buildings. For example, traditional double glazing has a U-value of 1.1, and triple glazing has a u-value of 0.7. An insulation value of 0.4 is therefore 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 realised 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.

Good insulation values, thinness, low weight, noise reduction and tempering are all good properties for various industries.

Industries in which BENGglas is widely applied include the automotive industry, appliance construction (refrigerated display cases, wine coolers, refrigerators), mechanical engineering, greenhouse construction, window frame construction and modular construction.
