ENERGY LINE 78mm profile

 

Description

ENERGY LINE 78mm windows are characterised by a line profile highlighted by rounding of r 4mm radius. They are made of three-ply square timber which is 78mm thick. These are energy efficient windows with a frame thickness of 78mm. Such a deep profile guarantees a much better parameters for energy save than standard windows with a profile of 68mm. Energy efficiency rating of our windows has been increased by nearly 30% by using glass with thermal conductivity coefficient of U=0,7.
