The OKNA.ua catalogue of profile systems has been supplemented with Veka profiles with a mounting width of 76 mm

The OKNA.ua specialised platform has been updated in the help section "Profile systems". Veka PVC profiles with an installation width of 76 mm have been added:
These systems are also available in the Energy Efficiency Calculator.

For example, for a double-sash window (WxH) 1780x1460 mm with a 44 mm wide double-glazed unit (4i-16Ar-4-16Ar-4i), the heat transfer resistance of the window will be:This exceeds the current Ukrainian requirements. According to DBN B.2.6-31:2021, the minimum permissible value of the reduced heat transfer resistance of windows is Rqmin = 0.90 m2-K/W (temperature zone I).
OKNA.ua recommends choosing designs with R-values of 1.0 - 1.1 and above to make the best use of your investment and meet future requirements. As the requirements for energy efficiency of windows are constantly increasing.

The systems are also available in the Wind Load Calculator for Windows. Both profile systems meet the requirements of DBN B.1.2-2:2006 "System of ensuring reliability and safety of construction objects. Loads and impacts. Design standards".
