Questions from Denbigh
What is the most common rectangular roof lantern size?
Sizes of 1000 × 2000 mm and 1500 × 2500 mm are common standard sizes for kitchen and dining extensions, but the right size is the one that matches your kerb. If your kerb is not built yet, our sizes guide helps you pick a standard size first.
Which way should the ridge run?
The ridge runs along the longer side. On a square opening there is no ridge and the lantern becomes a pyramid.
Is it worth having solar-control glass in Denbigh?
With the midsummer sun about 60.3° high at noon, roof glass in Denbigh gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
Do I need planning permission for a roof lantern in Denbigh?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your county or county borough council before ordering.
