Nature E92

The NATURE E92 window has been developed out of M SORA’s commitment to environmental responsibility. Instead of synthetic insulation materials – the manufacture of which consumes massive amounts of energy and produces large carbon emissions – these windows are made using only natural resources, wood and air.


  • materials used for the production are environment-friendly and recyclable
  • colours on inner and outer faces of the window can be different, creating a great array of colour choices


  • quality natural materials
  • by purchasing and installing these windows you will help cut carbon emissions


  • Wind resistance (EN 12210): Class C2/B3 (single and double casement)
  • Watertightness (EN 12208): Class 8A (single casement) and class 7A (double casement)
  • Air permeability (EN 12207): Class 4 (single and double casement)
