Quality product. Mine was a conservation light with recessed flashing and the central conservation bar. Aesthetically, a very good looking product. Solid quality product with exceptional glazing standard. Very pleased and worth every penny.

Reviewing VELUX GGL MK08 SD5J2 Conservation Window for 90mm Tiles - 78cm x 140cm
31st August 2020
They arrived from Roofing Superstore very quickly, excellent service! Because the weather has changed we're now waiting for drier weather for them to be installed. Conservation Style were specified by the Conservation Officer - personally I find them ugly, but there's no choice in these circumastances, ugly is better than nothing & it's not Velux's fault. Slight panic that they wouldn't go up through the loft hatch - they are being installed before the main loft conversion starts.
Sorry, there was a problem loading the reviews. Please try again.
