Better insulation and less noise

Optoglas provides 30% better insulation than equivalent double-glazing, and has a better U-value (2.2) than a double-glazed pane. A U-value of 1.7 can be achieved if a special, neutral energy glass is used – equivalent to a triple-glazed pane (DS 418).

Optoglas absorbs sound. For further information, please read Delta’s report. For the moment it is only available in Danish.
