Velux roof windows
Velux have been around for many years now and the quality has always been very good in comparison to other manufacturers, I’ve been fitting them for many years and it seems that every six months something or some detail seems to have been improved. They continue to evolve their products regularly which can be a bit of a menace when writing an article or making a video but I will do my best to keep my facts as up to date as possible.
Although at the moment here in the U.K. Velux roof windows seem to be the market leader in terms of popularity, there are many other makes you may wish to consider, see my article on roof windows that lists the most common alternative to Velux.

Velux Pine frame – GGL
The classic pine framed Velux has been around for many years now but is always evolving and becoming a better finished product, finished with a triple coating of clear varnish it’s a modern classic. Pine frame has the Code GGL.
Velux White uPVC – GGU
Velux originally only offered the very nice light varnished pine finished, however growing in popularity now is the white uPVC version introduced to the market. The white framed version coded GGU is high quality moulded polyurethane with a timber core and is ideally suited to high moisture environments.
Many of my customers liked the Idea but were concerned that the finish may look cheap and shiny like a normal double glazed window, If you are unfamiliar with the finish I will try to show it here as best as possible. I can tell you though it doesn’t look cheap and shiny, the best way I can describe it is micro stippled, very pleasant.

A nice feature of Velux windows and some other manufacturers now is the three stage Locked – Vented and Open positions of the top handle / bar.
- Stage 1 The bar is flush to the window and the window is locked
- Stage 2 The bar is opened slightly the window is still locked but vented
- Stage 3 The bar is fully open and the window is unlocked and can be opened
You can clearly see the vent which also boasts an insect filter built into the window frame.
The Velux Integra roof window range
The Velux Integra roof window range, electric and solar powered roof windows are ideal for out of reach situations and for adding that extra level of comfort. They are available in a choice of natural pine or white polyurethane finish and offer automatic closure when they sense rain. The motor is completely hidden and wiring is very easy but should be installed by a qualified electrician.
Velux Flashing kits
There are quite a few flashing options for Velux windows, a flashing set is purchased alongside the window as the roof window and the flashing are two sperate items. The purpose of the flashing set is to make a waterproof installation into a specific type of roof covering. here are the options.
Consider the Velux minimum roof pitch…
IMPORTANT – Please check that the flashing kit you need fits the angle of your roof, lots of people including local planning officials get caught out by looking at the minimum 150 angle stated for the Window but forget the Flashing set has a minimum angle also.
