Velux Window Advice

[wcavanagh]

Architect has specified the following.

(U Value to equal or better 1.3 W/m2K)

Install the following Velux roof windows in positions as indicated on the plans and elevations, complete with Flashing Kit (code: EDN2000) for slate roof finish including recessed flashing, insulated internal collar, underfelt collar and all fixings in accordance with the manufacturer’s printed instructions:

• Hall: Velux GGL, FK04 or MK04 to be confirmed with client, manually operated central pivot, white polyurethane internal finish, 780(w) x 1000mm(h)

Builder has come back with.

2 New double velux windows to be installed on both sides of the roof over the kitchen and lounge area. Material cost £1750

I have asked him to confirm, etc. But I dont see Velux selling a "Double" unit. Is that right?

Also are their any equivalents?

Fakro seem to crop up.

Also would treble glazing make a big difference on this size window? Reason I ask is all other windows will be triple glazed. We are in a bit of an exposed area in Scotland and very close to a road.

Cheers,
Will

You can have single, double or triple velux windows
I bought triple glazed skylight for my extension.

Go for velux, triple if you want, they're tried and tested and not that much more expensive than other makes.
