A sustainable approach to window design

Sustainability is fundamental to the VELFAC design philosophy. All our windows feature FSC® certified pine, with slim profiles designed to allow up to 15% more daylight into the interior. Wood treatments are water based and around 50% of aluminium used in the production of VELFAC profiles comes from recycled sources (85% produced using hydroelectricity). Our manufacturing facilities are also fully ISO14001 accredited, as is our Environmental Management and Audit System.

As a company with impeccable sustainability credentials, we are ideally placed to provide the advice and guidance required to meet project-specific sustainability targets, including:

  • detailed information on VELFAC sustainability performance including individual U-values for each window unit, and area weighted U-values for specific projects
  • evidence of the sustainability of VELFAC products including:
    • FSC® certification of our pine framing
    • ISO14001 accreditation of our manufacturing facilities and our Environmental Management and Audit System
    • details of our water-based wood treatments
    • proof that we use recycled aluminium in external frames, and aluminium produced using hydroelectricity
    • an environmental declaration detailing our cradle to grave approach to sustainable manufacture and performance
