Two identical Velux windows not staying open the same amount (final, small issue on build that is frustrating :-) )

[sneakyben]

Hi,

 

I have a new extension... with only one real problem that I have not been able to fix...

 

I am hoping some people here could help me with a solution to my issue, with our new extension...

 

We have fitted 2x Two identical Velux windows... but they are not staying open the same amount... is this normal? How can we fix it? (or even get them open more?)

[I am aware they wont ever open a lot, due to the shallow slope of the roof]

They should open loads more than that.  Pull harder on the handle.

[sneakyben]

They do open more than that, but this is where they 'settle', after the handle is let go after pulling to fully open (i.e. there is no restriction to the opening)

Ours seem to have a lot more friction and wind permitting, stay at any angle you choose , even one that would let the rain in.

What pitch is the roof? It can have an effect on centre pivot windows.

You could ask Velux if some stronger friction springs are available.

The pitch is pretty shallow... can't remember exactly but quite a lot less than 45deg... I will ask Velux re springs... does anyone know if these are an expensive thing to replace? (or a pain in the bum to fit the replacements?)

[JamesP]

Here is a video of spring replacement. Velux are usually very helpful.

Is the friction adjustable? Ask Velux.

 

Google found this but I've no idea ifbit fits your windows...

interesting resolution: velux suppling stiffest springs they do FOC

you can adjust the springs, we have similar set up to you, and needed to adjust the pre load on the springs to enable the window to stay open at all. There are videos and pics online of how to do it. Best done at install time as some of the covers on the outside need to be off to access the springs and adjusters
