Sustainable and innovative products

VELUX solutions span a wide product range from large modular skylight constructions to smart phone apps and decorative blinds. We constantly aim to set the trend in innovative building design and window products for new build and retrofit.

The key drivers in our product development activities are healthy and sustainable buildings with more daylight, more fresh air and nearly zero energy consumption. VELUX windows are carefully designed to minimise the heat loss through the windows and to make the most of the solar heat gain.

“High quality” and “made to last” are key characteristics of all VELUX products, which are designed and manufactured for up to 40 years of service life.

Product categories

Our product programme ranges from complete skylight systems to roof windows, sun tunnels, blinds and shutters, manual or electric. In line with our vision, all products are developed to provide daylight and fresh air through the roof to create healthy and sustainable buildings.

The energy efficiency of our products is continuously improved to comply with the highest standards. All products are designed to optimise the energy balance of the individual window. At the same time, VELUX products can be combined to take full advantage of the solar heat gain through the windows, natural ventilation to bring fresh air into the building, and sun screening products to prevent overheating.

VELUX windows are sold in approximately 100 countries around the world, and our solutions are suited for any climate.

The VELUX product categories comprise:

  • Roof windows
  • Electrically- and solar-powered windows
  • Installation products
  • Flat-roof windows
  • Sun tunnels
  • Blinds and shutters
  • VELUX Modular Skylights

VELUX Modular Skylights

VELUX Modular Skylights are a new business area launched in 2012 and based on the same high-quality and sustainable approach as traditional VELUX products.

VELUX Modular Skylights is a new business area launched in 2012 and based on the same high-quality and sustainable approach as all other VELUX products.

Co-created with architects Foster + Partners, VELUX Modular Skylights are an innovative new daylighting solution for commercial buildings and public institutions. The large amount of daylight obtained through longlights, ridgelights, northlights or atrium solutions reduces the need for electrical lighting. At the same time, built-in solar shading reduces the need for cooling on warm days.

VELUX Modular Skylights can be opened to create a stack effect for natural ventilation of the building. The complete skylight solution can be automatically controlled by a Building Management System to synchronise with season and time of day, outdoor weather conditions and use of the building at different times of the day.

Since their launch, VELUX Modular Skylights have gained a strong foothold in an increasing number of markets. The new solution is praised by end users and professionals for its positive contribution to energy efficiency and indoor climate. The high energy performance of VELUX Modular Skylights comes from the use of low-energy panes and the frame material (pultruded fiberglass), which insulates 500 times better than aluminium.

VELUX Modular Skylights in outstanding BREEAM building

Geelen Counterflow’s new office building in the Netherlands has achieved BREEAM Outstanding certification. VELUX Modular Skylights were chosen for this exemplary building that produces 50% more energy than it uses.

The client liked our design and materials, which fit their ambition of BREEAM certification. They chose a triple-layer sun-coated pane and roller blinds to avoid overheating. They were impressed by the airtightness of the VMS solution, and the prefabricated modules allowed fast and fool-proof installation,” said Jack Kenters, Account Manager in VELUX Nederland.

Generating ideas for future products

The online VELUX Ideas platform was launched in 2012 as an idea-generation and idea-development tool in our product development departments. In 2015, the first sales companies gained access to the platform in order to widen the scope and diversity of ideas brought forward by VELUX employees.

During 2015, VELUX Product Management used the platform to run an idea-generation campaign among colleagues to kick-off the development of a new, blackout energy blind. Almost 50 ideas were posted, ten of which could be used either directly or as inspiration for other improvements.

The roll-out of the idea-generation platform will continue in 2016 as an important element in our Group’s growth and innovation strategy.

New Blackout Energy Blind

A novel Blackout Energy Blind was launched in 2015 to meet customer demand for total blackout at night and high insulation effect to improve comfort and energy efficiency in the home. 

According to the feedback from homeowners in the pan-European Healthy Homes Barometer 2015, ‘a good night’s sleep’ is the single most important factor of a healthy home. The new Blackout Energy Blind was developed to meet this demand. 

We asked homeowners what they expect from a blind. The blackout effect was by far the most important quality. We used this knowledge to develop a new blind that ensures complete darkness in the bedroom,” says Lise Bruhn, VELUX Category Manager. 

Blackout and insulation go hand in hand 

At the same time, the insulation effect of the new blind has been increased significantly compared to other blinds currently available thanks to the innovative double-layer construction of the blind. 

The life-cycle analysis of the new blind combined with a GGL VELUX window shows that net CO2 savings are doubled when the window is fitted with the new Blackout Energy Blind. This means that the CO2 impact during production and distribution of the products is paid back after only seven years by solar heat gain and the high insulation qualities of the window-blind combination. 

The Blackout Energy Blind was developed based on the Active House Vision to create sustainable buildings with low energy consumption and a strong focus on the health and well-being of people inside the home.

Affordable solutions for European housing shortage

In 2015, the international consultant company Accenture analysed and calculated how much a European family can save by turning their attic into living space using VELUX products and solutions instead of buying a bigger house.

Green Solution House

The VELUX Group was strategic partner in developing the Green Solution House, a visionary and sustainable hotel and conference centre in Denmark.

Green Solution House explores circular sustainability. The hotel and conference centre is certified to the standards of the German Sustainable Building Council (DGNB). The design is based on the criteria of the Active House vision and inspired by the cradle–to-cradle life cycle concept.

Comfort through daylight and natural ventilation is one of the major themes in the building design. Through an innovative combination of VELUX products such as VELUX Modular Skylights, roof windows with solar shading, flat-roof windows and sun tunnels, the hotel and conference facilities are flooded with natural light and fresh air.

The Green Solution House showcases how it is possible to build resource-efficient and nearly zero energy buildings with a high level of comfort and an attractive design.

Life Cycle Assessments

In 2015, work continued on fine-tuning the model for Life Cycle Assessment (LCA) of VELUX products. LCA assessments are now complete for all major products for use in Northern Europe.

The analyses document that the main environmental effect of a VELUX roof window is in the use phase.
The energy savings over the lifetime of the roof window exceed the energy consumed in the production process − consequently, the roof windows provide net CO2 savings over their complete life cycle.

CO2 savings over the lifetime of a VELUX roof window

Life cycle CO2 emissions calculated for a VELUX roof window GGL with one change of the pane, installed in a typical house in Würzburg, Germany. Transport is included in each of the steps from raw material to disposal.

The energy contribution of a roof window can be increased by adding blinds and shutters to improve insulation during winter and to avoid overheating in summer.

LCAs are the first step towards Environmental Product Declaration of windows and accessories. VELUX Environmental Product Assessments have been developed on the basis of the international standard methodology for assessment of LCA (ISO 14040) in cooperation with the Danish FORCE Technology Institute, which specialises in Life Cycle Assessment.

VELUX Environmental Product Assessments are designed to comply with the methodology of the European Standard EN15804 (Environmental Product Declaration for Building Products and Materials).

Documenting the use of chemicals

The VELUX Group controls and documents the use of chemicals in our production and our finished products.

We control and document the use of chemicals in our production and in our finished products. We continuously improve our documentation procedures through a systematic approach to mapping of chemical substances and through close dialogue with our suppliers.

France is the only VELUX market that has a labelling system for emissions of chemicals to the indoor climate. All our tested products (roof windows, flat-roof windows, VELUX Modular Skylights and sun tunnels) have the highest A+ rating.


In close cooperation with our logistics partners, we continuously search for ways that will optimise the loading of trucks and reduce the environmental impact of transport.

In close cooperation with our logistics partners, we continuously search for ways to optimise the loading of trucks and reduce the environmental impact of transportation.

Using our Cube packaging system, the windows are wrapped with stretch foil and stacked horizontally in the trucks to allow as many windows as possible in each load. The windows travel from production site to point of use in the same packaging, with only the stretch foil being discarded. The packaging allows easy opening by the installer and reduces the number of heavy lifts required by the installer.

All cardboard used for packaging can be recycled.

Product quality

Quality is a cornerstone of the VELUX business, essential to fulfilling our vision of leading the development of better living environments with daylight and fresh air through the roof and to be rated as the best in the eyes of our customers. Our roof windows are developed to last for a service lifetime of 40 years or more.

Quality has top priority at all levels from purchasing through development and production to after-sales services. We manage quality in products and processes by the VELUX Group Quality Policy and the VELUX Quality Management System, based on the ISO 9001 standard.

In our customer survey carried out in 2015, 99% of the installers and dealers agreed that products from the VELUX Group are reliable and of high quality.


The VELUX Group applies a global procedure for qualifying new suppliers.

The VELUX Group applies a global procedure for qualifying new suppliers. Before contracting, careful screening takes place to ensure that suppliers are able to meet our requirements in terms of quality, technology, sustainability and logistics.

The screening includes supplier self-assessment, auditing of quality processes, testing of the materials they will supply and careful risk assessment.

Development and testing

The VELUX product development organisation designs new roof windows and supplementary products or modifications to existing products in close dialogue with the local markets.

The VELUX product development organisation designs, develops and improves roof windows, sun tunnels and products for installation, ventilation, electronic operation, sun screening and decoration in close dialogue and corporation with the market and supply organisation.

In 2015 alone, the 270 engineers and designers at the VELUX development departments came up with more than 20 major improvements to existing products or new products.

With an expected product life of 40 years, testing of our products is an important part of the development process to make sure our products are durable and live up to our quality standards. In the course of our product development, new products typically go through at least 40 tests, including:

  • Wind tunnel tests, where windows and flashings are tested in full scale and exposed to some of the world’s most severe rain and wind tests to make sure they are able to withstand extreme weather conditions
  • Climate tests, where windows are exposed to extreme temperature changes from very hot to very cold, as well as snow, ice and high humidity
  • Solar tests that simulate intensive sun impact and its effect on windows and accessories
  • Mechanical tests of strength, durability for wind load and heavy snow load, or long-term use of windows, such as the 25,000-times opening and closing test
  • Technical features of great importance in terms of CO2 reduction are also tested, such as U-value, air permeability and ventilation.

High-quality manufacturing

The wide range of VELUX products is manufactured at production sites in nine countries.

VELUX products are manufactured at production sites in nine countries. All production sites are certified to the ISO 9001 quality standard, which means that they are regularly audited by third parties.

Our own quality team audits production sites regularly to ensure that windows and accessories leaving the factories meet the required specifications and VELUX quality standards. During 2015, 35 warranty quality audits were conducted.

Materials, components and finished products are systematically sent from the factories to the VELUX Group Quality Lab to monitor quality levels at all times. Process controls built into the production equipment and performed by operators, combined with inspection and testing of finished products, are part of the quality management system that ensures consistent and high standard of VELUX products.

The components test programme includes:

  • Corrosion resistance of metal parts
  • Wood impregnation
  • Wood humidity
  • Glass quality and lifetime.

The finished products test programme includes:

  • Durability tests
  • Resistance to rain and snow at different wind speeds
  • Airtightness
  • Low temperatures
  • Soundproofing.

The VELUX Manufacturing Model ensures continuous improvements

We apply a formalised approach to continuous improvement of the manufacturing processes. The approach is inspired by the Lean methodology and termed the VELUX Manufacturing Model (VMM). VMM has been one of the cornerstones of our production for more than ten years.

Every production company goes through a VMM assessment once a year. The assessment is carried out by 12 internal VMM assessors, and the results provide a sound basis for internal benchmarking and continuous improvement.

How do they do it?

Discovery Channel visited one of our factories to make a programme on how we produce roof windows. It is part of the series shown around the world called “How do they do it?”.

Installation and use

Our goal is to make products that last a lifetime, are easy to install and use with minimum need for maintenance.

Our goal is to make products that last a lifetime, are easy to install and require minimum maintenance. Our customer satisfaction survey shows that 99% of installers and dealers agree that the VELUX Group offers reliable products of high quality.

Only 0.6% of all sold VELUX roof windows require warranty service in the first three years. We offer an extensive service/support network in the event that service or repair is needed.

The annual customer satisfaction survey shows that 94% of installers and dealers are satisfied with our after-sales services and agree that our products are synonymous with high quality.

Product recall and warnings

One aspect of being a Model Company is to maintain high quality levels at all times.

As a Model Company, we strive to maintain high quality levels at all times. Despite the unrelenting focus on quality, things may go wrong; in 2011, the VELUX Group had to issue a rare product warning due to the risk of glass breakage in certain small roof windows. The warning is still in effect.

Even though the risk of personal injury in connection with glass breakage is marginal, we take the safety of our customers very seriously. We therefore set up local task forces and offered the affected customers a replacement pane ex gratia. There may, however, be some local deviation from the global ex gratia offer.

No product warnings or recalls have been issued since 2011.
