Making a Velux window non-opening

casper_gutman

My extension is nearly finished. I can't get the boiler installation signed off because the flue exits the roof too close to an openable Velux window. The installer suggested the best way to resolve this is to make the window permanently non-openable.

Any suggestions for the best way to achieve this, ideally without making any change to the look of the window?

Clear sealant between the opening section and the frame, plus screws to ensure it can't be opened?

Why wasn't the problem identified during the build process?  Isn't this something a competent builder or designer/architect should know about?

Long answer:

• The drawings showed the flue going through the wall and not the roof, but the need to clear the eaves with the flue hadn't been adequately considered and this would have meant either the boiler being so low on the wall that the washing machine couldn't be below it or the flue extending too far out across the accessway outside. So, it was moved to go through the roof as dealing with the window issue seemed the lesser of two evils.

Short answer:

• Yes, I blame the architect.

Try contacting Velux customer care to see if they have a kit to suit your purpose.

Just get a couple of L brackets and fit um to the frame and opening leaf.

Inspired by the above I contacted Velux and received a prompt and informative reply (thanks Eldi_Dos - one of those "why on Earth didn't I think of that?" moments!).

In case anyone else is ever looking for an answer to the same question as me, Velux recommended screwing through from the outside of the frame, after it's been installed but before the flashings are on, being careful the screws don't extend so far through the sash as to be visible internally, at the locations indicated by arrows in the picture below:



As an alternative, they suggested a security lock (part number Z0Z 012K1) could be used, but I'm not sure this would be enough to get the boiler installation signed off as I could easily remove it as soon as the installer/building control weren't looking!
