Velux has established itself as a market leader in the roof window segment and offers a wide range of products for timber construction and interior finishing projects, from awning windows to folding solutions to flat roof exits. The Danish company consistently relies on wood-aluminum constructions, which are used in passive house projects as well as in the energy-efficient renovation of existing buildings.
Product lines and applications
The core portfolio of Velux is divided into three main categories: awning windows with centrally arranged handle strips, folding-awning windows with top-mounted operation, and flat roof solutions for roofs with slopes up to 15 degrees. The current window generation combines pine inner cores with external aluminum shells – a material mix that minimizes wood moisture problems and extends maintenance intervals.
In the awning window segment, the GGL series is considered the best-selling model. With installation dimensions ranging from 55 × 78 cm to 134 × 140 cm, the series covers most private and commercial applications. The triple glazing achieves Uw values up to 0.86 W/m²K and thus meets the requirements for window systems in passive houses. Tool-free installation via a flashing frame system noticeably speeds up installation on construction sites – an argument that carries particular weight in larger roof extensions or multi-family houses.
Competitive position and differentiation
In direct comparison with competitors such as Roto or Schüco, Velux positions itself in the premium price segment. The company justifies its premium strategy with increased service life, improved sealing systems, and a comprehensive service network. While Roto scores with modular hardware solutions, Velux relies on closed system architectures – an approach that receives mixed reviews from architects and timber construction engineers.
Particularly in multi-story timber construction, such as CLT solid wood projects, fire certification plays a central role. Current generation Velux roof windows feature P4A safety glazing and automatic smoke and heat extraction functions – features that are increasingly becoming standard in larger residential construction projects.
Current developments and product innovations
In recent months, Velux has expanded its smart home integration. The Velux Active platform allows connection to Apple HomeKit, Google Home, and Amazon Alexa. Sensors monitor room temperature, CO₂ content, and humidity levels and automatically control window opening and sun protection. For carpenters and joiners realizing interior finishing projects with Velux roof windows, this means: the cabling must already be taken into account in the planning phase – an aspect that is sometimes underestimated.
At the same time, the manufacturer has revised its flat roof product range. The new CVP series dispenses with traditional domes and instead uses flat glass surfaces that are integrated flush with the roof covering. The reduced structure lowers the structural height to 15 cm – an advantage in retrofitted roof extensions with limited space.
Outlook: Timber construction and window insulation
The tightening of energy standards in Europe is forcing all window manufacturers to further improve U-values. Velux is responding with four-pane glazing, which is currently being tested in Scandinavia and is expected to achieve Uw values below 0.7 W/m²K. However, whether the additional pane of glass will be accepted by the market also depends on acceptance of the increased frame thickness – a trade-off that is not always practical in interior finishing.
For joinery shops and timber construction companies, Velux remains a reliable, albeit cost-intensive partner. The combination of wood-aluminum frames, tool-free installation, and smart home capability meets the requirements of modern residential construction projects – provided that planning coordination takes place in good time and the interface to building automation is clearly defined.
