Questions from Isleworth
Will anthracite get hot in the sun?
Dark frames absorb more heat than white, but lantern frames are designed for it. The bigger effect on room temperature is the glass, which is why solar-control glass matters on south-facing roofs.
Does anthracite show dirt?
Less than white. Dust and pollen are more visible on dark gloss finishes, which is why most grey lanterns use a matt or textured finish.
Do I need planning permission for a roof lantern in Isleworth?
Often not, but it depends on the roof, the property and whether it is listed or in a conservation area. Check with your district, borough or unitary council before ordering.
Is it worth having solar-control glass in Isleworth?
With the midsummer sun about 62.0° high at noon, roof glass in Isleworth gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
