Velux windows - maintenance

Jun 09, 2010 3 Replies

HI Folks



We've been in this (new-build) house nearly four years now - all of the upstairs rooms have Velux rooflights.



Looking idly out of one of these windows (as you do!) I noticed that there's an amount of flaking varnish and grey discolouration, with a few small splits along the grain in the timber that forms the lower edge of the fixed window-frame.



Velux's website says --------------- The wood should be treated at least every four years and otherwise according to the set requirements.



-and- windows exposed to strong heat, strong sunlight and/or an especially high level of humidity (e.g. in a kitchen or bathroom) should be treated at least every two years.



Treatment: any surface treatment (varnish or paint) is removed, and the cleaned, dry surface is primed and lacquered/painted with waterbased acrylic varnish/paint. If the varnish/paint is damaged, the same treatment is applied to the areas in question. VELUX offers a repair kit with original repair varnish or paint.



When you treat the wood, it is important to cover the gaskets to prevent varnish/paint rubbing off on the gaskets, as this will make the gaskets stiff/hard and spoil their effect.



Guarantee depends on maintenance Please note that our guarantee depends on on-going maintenance being carried out in accordance with the above-mentioned maintenance directions.

So - what's the best way to treat this ?



- sand down / remove the areas with flaking varnish



- treat areas with splits / discolouration with something (?what?)



- refinish with waterbased acrylic varnish


- maybe a light coat of varnish to all other timber surfaces, as a preventive measure - I can't belive that they really expect people to strip down & refinish all parts of each window every 2 - 4 years - or is this an amount of 'backside-covering' for guarantee purposes ?



Thanks Adrian


Hi Adrian,

I have exactly the same issue. I'm wondering, another four years on, if you've managed to find a solution to this maintenance problem?

Kind Regards,

Mike

We've had two of these windows for nigh on 20 years now. One on a north facing slope and the other on a south facing slope, I've only treated the south facing once in that time, though the other needs a touch up now.

I found the Bosch Delta sander very useful. The green one I have has a dust extractor outlet unlike the blue one. Saved a lot of mess and cleaning up.

If you fit Roto plastic roof windows, you don't have any maintenance to do.
