We are happy to introduce the new IV78 profile system wooden window which offers the following advantages in comparison with the traditional IV68 wooden window profile system

• The IV78 profile is 10 mm thicker than the IV68 profile (thickness is 78 mm), therefore it offers better thermal characteristics. 
• Up to 44 mm thick glass packets may be installed into the windows. This is improving the heat insulation and the sound insulating characteristics.
• The IV78 profile is much more rigid than the standard IV68 profile.
