Questions from Harpenden
Is self-cleaning glass the same as solar-control glass?
No. Self-cleaning is a coating that sheds dirt; solar control reduces heat gain. Many lantern units combine both.
Does it work under trees?
Less well. Sap and leaf debris build up faster than daylight and rain can deal with them, so lanterns under trees need more regular rinsing.
Can you fit a roof lantern in Harpenden?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
Is it worth having solar-control glass in Harpenden?
With the midsummer sun about 61.6° high at noon, roof glass in Harpenden gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
