Environmental declaration

Invironmental declaration logoVELFAC is the first window manufacturer that has prepared an environmental impact statement, based on an investigation by the DTI (Danish Technological Institute) which shows the VELFAC 200 system’s environmental impact.

By far the largest amount of energy in a building is lost through windows (90%). You can reduce the environmental impact by using VELFAC windows with low heat loss (low U-value) and high-energy contribution (high g-value).
