Velux owners 2g v 3g

Hi all,

 

Thought I'd ask on this thread rather than starting fresh......

 

Does anyone know if a warm roof buildup requires a 300mm upstand over a more standard 150mm?

 

On discussing a job with velux, it appears they suggest 300mm for warm roof, which sounds large. 

 

Anyone have any knowledge on this?

Not sure what you mean by a 300mm upstand. I fitted four 3G velux in our warm roof, used the Std flashing kits for a slate roof. Fitted extra insulation around the frames. Been in over a year with no problems. 3G is much quieter than the 2g versions

Thanks for the response, but this is a flatroof.

 

Still, I'm confused by 300mm for an upstand, but I'd love to hear opinions of others.
