Is there no dealer near you? Then ask your local glazier to contact BENGglas via info@bengproducts.nl.
What is the U-value and why is it important?
The U-value indicates how well glass insulates. Simply put: the lower the U-value, the better the glass retains heat in the winter – and keeps it out in the summer. This way, you save on your energy bill and increase your living comfort.
The U-value is influenced by various factors, such as:
- The coating on the glass
- The filling between the glass layers (e.g., air, gas, or vacuum)
- The cavity width – thus the space between the glass layers
How does BENGglas score compared to other types of glass?
Here is an overview of the average U-values per type of glass:
- Single glazing: 5.8 (insulation? Hardly.)
- Double glazing: 1.10
- Triple glazing: 0.70
- Other vacuum glass types: between 0.45 and 0.70
- BENGglas: from 0.35 to 0.50
In short: BENGglas has by far the best insulation value of all.
This way, you save extra on your energy bill!
