VELUX roof windows can be coupled together side by side and / or one above the other to provide additional light and create an attractive effect. Here's a handy hint: you need to provide glazed areas equivalent to 10% of the room's floor area to achieve a good level of natural daylighting. You can improve the overall effect by increasing this ratio to around 20% and also by using several smaller windows rather than one or two large ones.
These are just two examples of the wide range of VELUX roof windows we install.
Centre Pivot Roof Window (GGL)
The GGL is quick and easy to install, remarkably tough and durable and
finished with a clear varnish (known as TOPfinish™) to enhance the
pine's aesthetic appeal.
GGL can be installed in roof pitches between 15° - 90°.
Available in 8 Standard Sizes.
Top-Hung Roof Window (GHL)
GHL roof windows are perfectly suited to low pitched roofs. Opening outwards
without intruding into the room space, GHL windows create a feeling of
space and provide a free, unrestricted view. As a result these are best
suited to rooms where a lot of furniture is required, such as a bedroom
for example. The GHL is quick and easy to install, remarkably tough and
durable and finished with a clear varnish(known as TOPfinishTM) to enhance
the pine's aesthetic appeal.
Installation of GHL is possible for roof pitches between 15° and 55°
, and up to 77° with the use of special springs.
Available in 5 Standard Sizes.
