Can I have a manual opening vent?
Manual vents are rare on lanterns because they are out of reach. Electric operation is standard.
What happens if it rains while the vent is open?
With a rain sensor the vent closes automatically. Without one it stays where you left it, so a sensor is worth having.

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 Horsham?
