The A ++ energy efficiency class

In Lithuania, from January 1, 2021, all new construction buildings must comply with the A ++ energy efficiency class. Energy-efficient buildings have good thermal insulation, are airtight, minimize thermal bridges, and have suitable windows and doors. It is estimated that up to 40% of the heat of a building is lost through poor quality windows. Since 2016, Doleta has been manufacturing and installing Doleta Modern 10, a unique system window that meets the requirements of A++ class. The calorific value Uw 0.8 is achieved due to the aluminum-forged narrow profile wood and the certified components used. The thinner the profile, the more durable the window, as it withstands more openings, looks more aesthetically pleasing and allows more light to enter the premises.
