Questions from Truro
Does an opening vent let insects in?
When open, yes, as with any window. Some ranges offer fly screens.
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.
Is it worth having solar-control glass in Truro?
With the midsummer sun about 63.2° high at noon, roof glass in Truro gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
