Questions from Derry
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.
Can a vent be added later?
Usually not to an existing fixed lantern. Decide before ordering.
How quickly can I get a roof lantern in Derry?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for BT47.
Is it worth having solar-control glass in Derry?
With the midsummer sun about 58.4° high at noon, roof glass in Derry gets strong summer sun. Solar control is recommended for large or south-facing lanterns.
