Passivhaus Windows

88mm System

What does Passivhaus certification mean?

In simplest terms, it is a building insulated to a very high standard with openable windows manufactured to the highest standard of thermal, wind and rain proofing performance. System 88 has been awarded this certification by the Passivhaus Institut in 2010 and hence, this window is a building component suitable for Passivhaus projects. The Kommerling System 88 window boasts an unbelievably low U value of only 0.86.

  • Window U value 0.86
  • 87mm outer frame
  • 6 chambers
  • Choice of 7 colours
  • Further 40 colours and 4 metallic finish options available

System Window

This innovative and award-winning system benefits from a number of key features, including the inherent 6 chambered, 88mm optimum frame depth design credentials. It can boast an impressive 0.7 W/(m²K) 'U' value, using Argon gas filling in the IGU, exceeding the Passivhaus specification and is designed to include high performance triple glazing as standard.

Energy conservation and the whole global agenda for the future of our planet is a high priority for not only governments, but for consumers too.

Within the system are a range of reinforcement options, including foam-coated steels and the PVCu sections are co-extruded with a Greenline lead-free skin and a full recycled internal construction. 

It’s also available in 44 different colour options plus the option of Alustar, an aluminium cladding section designed to meet the needs of architects and offering to use the entire RAL colour spectrum. The system also takes existing and standard UK tilt and turn hardware.
