Bibliography

This draft European Standard is the product standard fo insulating glass units, which defines insulating glass units, and ensures by means of an adequate evaluation of conformity to this standard that: - energy savings are made because the U-value and solar factor do not change significantly; - health because sound reduction and vision do not change significantly; - safety is provided because mechanical resistance does not change significantly.
