4 A comprehensive solution for airtightness allows creating energy-efficient buildings and additionally saves up to 30% of operating costs.
The technology is based on using Ruukki Energy sandwich panels and takes into account all possible elements that ensure airtightness of the envelope structure, including vertical and horizontal joints of the panels, the roof structure, joints between the roof and the walls, as well as additional sealants for windows and doors.
“High airtightness is the most economically expedient and environmentally friendly way to increase energy efficiency and reduce carbon dioxide emissions throughout the building’s life cycle,” said Andriy Ozeychuk, Rauta director. – The use of new technology allows to save up to 30% on air-conditioning and heating, increases the market value of the building and allows to get more points for certification according to the LEED and BREEAM systems. At the same time, the investment payback time is only 3 years.”
To confirm the high airtightness of the envelope structures after the building construction, its efficiency can be checked by a blower door test.
