Additional information basement windows

A large proportion of a house's heat escapes through poorly insulated windows. The ACO Therm® 3.0 reveal window for the basement can also contribute to reducing the annual primary energy requirement and transmission heat loss even more than required by the EnEV 2014. With its 4-chamber plastic sash, the 5-chamber plastic frame with thermal break and the profile depth of 82 mm, it achieves a heat transfer coefficient at living room window level.
