Our products

We want to deliver products that are sustainable from cradle to grave in terms of impact on climate, environment and use of natural resources.

Policy and goals

For several years, the VELUX Group has used Life Cycle Assessments (LCA) to measure and document the impact of our products from sourcing of materials to daily use and disposal.

In 2017, we broadened the concept of sustainable products to cover other aspects of the products impact on climate, environment and use of natural resources.

We perform LCAs for all new product developments and product upgrades. In addition, we are in the process of developing a comprehensive new tool for Environmental Product Evaluation that provides a systematic approach to sustainability indicators in our product development.

The tool includes new sustainability parameters in product development, without compromising our relentless focus on quality and a product lifetime of at least 40 years.


In 2017, we developed a new tool for Environmental Product Evaluation. The new tool is based on current and future EU regulation and takes a cradle-to-grave perspective on product development, focusing initially on five parameters:

Carbon emissions: performing Life Cycle Assessments of all new products and product upgrades according to the international ISO 14040 standard for LCA, the EN 15804 standard for Environmental Product Declaration for Building Products and Materials, and the EcoPlatform standard.

Energy balance: taking maximum advantage of the positive energy balance of roof windows thanks to the heat gain through the panes.

Sustainable sourcing: replacing fossil resources with renewables and using recycled materials instead of new materials.

End-of-life recyclability and recoverability: ensuring that our products can be disassembled and the materials reused in the best possible way.

Chemical emissions during use: minimising chemical emissions from materials used in the windows.


Our LCAs document that roof windows can provide net CO2 savings over their life cycle. This means that the energy savings achieved by the roof window due to the heat gain through the pane may exceed the energy consumed in the sourcing and production process.

The LCAs also show that energy savings over the lifetime of the roof window can be improved when energy blinds are added to avoid heat loss through the pane. New active solutions that open and close windows and blinds according to weather conditions make it possible to optimise the use of the roof window and can further improve energy and CO2 savings.

Next steps

In 2018, we will test a new Environmental Product Evaluation tool in our product development to minimise the impact of our products on climate, environment and natural resources over their life cycle. In the longer term, the plan is to extend the scope of Environmental Product Evaluation to include more parameters such as easy maintenance, reparability and replacement.  

In 2018, we will also conduct LCAs on the new VELUX ACTIVE product portfolio.
