How To Choose Your VELUX Roof Window

Step 1

Choose the type of window you want or need. There are several types available, including:

  • Centre Pivot - operated by a top control bar, these windows pivot from the middle. This makes them easy to operate, even with furniture below. They can also be installed lower than a bottom-operated window, providing a better view.
  • Top Hung - operated from the bottom, these windows open outwards for an uninterrupted view. They provide a feeling of space and maximise the amount of light.
  • Flat Roof - stylish and practical, these windows allow light to flood into the home. Some can also be opened to let fresh air in.
  • Vertical - often combined with other VELUX roof window products, vertical windows can be used to flood a space with light and create panoramic views.
  • CABRIO Balcony - opening in seconds, these windows turn into a balcony to create a stunning space full of light and fresh air.

All VELUX roof windows come with grey aluminium exterior covers as standard. The closest colour match code is RAL 7043.

Step 2

Choose the size of window you require. If you’re replacing an existing window, this may already be determined for you. However, if you’re planning a new space the size of VELUX window you choose is vital. Larger windows add more light to the space, affecting the look and feel of the room. As a guide, VELUX recommend that the glazed area is 15% - 20% of the overall floor area of the room.

Step 3

The type of glazing available may be determined by the type and size of window you choose. However, you may have different options available to you. VELUX glazing provides different levels of heat insulation, sound insulation, strength and protection from the weather.

Glazing 62 - offering premium heat insulation, this glazing helps keep heat from the sun indoors. It also reduces the noise from rain, as well as other outdoor pollutants, and reduces the amount of dew that forms on the window.
Glazing 66 - this glazing provides enhanced energy efficiency and also has an easy-to-clean coating. It has a laminated inner pane for safety and reduces the amount of dew on the window. Heat from the sun is kept in, while outside noise is reduced.
Glazing 67 - the best performing triple glazed option from VELUX, this glazing provides optimum thermal efficiency and noise reduction. It also has an anti-dew coating and is easy to clean.
Glazing 68 - this triple glazing offers all VELUX premium features (including noise reduction, safety lamination and toughened glass) along with better energy efficiency. This reduces the feeling of cold that could come from a window in winter.
Glazing 69 - this glazing option is best for filtering out the heat from the sun, keeping your indoor space more comfortable. The three layer pane offers thermal efficiency, reducing the feeling of cold in winter.
Glazing 70 - providing maximum safety and energy savings, windows with this glazing have a laminated inner pane for safety and keep in heat from the sun. They also help to reduce outside noise and have enhanced protection from heavy snow and hail.
Glazing 70Q - with thicker glass and a laminated inner pane, this glazing provides enhanced security. It has protection from heavy snow and leaves, and reduces outside noise, while keeping heat in.

Step 4

VELUX offer three internal finish options that are designed to match your living space. All of the finishes offer the same high quality you would expect.

White Polyurethane Finish White Polyurethane Finish - perfect for contemporary interiors and humid rooms such as kitchens and bathrooms, windows with this finish have a thermally modivded wooden core encased in polyurethane. They are low maintenance and have no visible joints.
White Painted Finish White Painted Finish - provides a bright white finish with a discreet wood grain, making them great for modern interiors. They are painted before assembly for a flawless finish, and have high UV resistance to preserve the look for longer.
Pine Finish Pine Finish - great for traditional interiors, the high quadivty natural pine has a protective triple coat of clear lacquer to preserve the timber.

Step 5

Depending on which VELUX window you choose, there may be an option for how the window is opened and closed.

  • Manual - many VELUX windows will be manually operated using the control bar and handle. This is the simple option if your windows are easily accessible.
  • Electric - these windows use the INTEGRA system, a perfect solution for out-of-reach areas. Operated with a wall switch, the integrated motor runs almost silently. They also have rain sensors to close the window automatically if it rains.
  • Solar - these windows also use the INTEGRA system and have all the same features, but are powered by the sun so don’t need a power supply. The PV solar cell on the external frame requires exposure to sunlight.
  • Fixed - this covers a wide range of VELUX windows, including vertical panes, fixed window elements and domes.
  • Smoke Ventilation - specific windows where smoke ventilation is required.

Step 6

The insulation around your window is equally important, and VELUX provide a range of flashings to meet building regulations, integrate with your roofing material, and make your window weathertight. There is also a range of installation products to aid with this process.

You may also want to add a number of accessories to your VELUX window package, particularly if you’ve chosen the VELUX INTEGRA system. The VELUX ACTIVE package allows complete control of your windows, with smartphone compatibility.

To complete the look, an extensive range of VELUX blinds, shutters and awnings are available to match your interior and provide insulation or shading.
