Should a roof window on high ground be able to close itself?
Haslingden stands about 240 metres up, with high moorland around it, which makes exposure and wind-driven rain fair things to plan for. A window left open at breakfast can be wet inside by lunchtime. That is a daily-use problem, not a technical one, and it is solved by how the window opens.
What the options do
A manual window stays where you leave it. An electric one is closed from a switch or remote, and a solar one needs no cable. VELUX makes electric and solar models with a built-in rain sensor that closes the sash when rain is detected, and our guide to rain sensors explains how they work. Our page on electric or solar opening covers the choice between wiring and sunlight.
Who is it for?
A bedroom window that is opened every morning is the best candidate, because the habit is daily and you may not be there when the weather turns. A landing window that is rarely opened can stay manual. We ask who is at home through the day before we recommend anything.
The glass after a storm
Weather leaves marks, and how easily you can clean the outside depends on the slope and the window. We explain that, and the controls and blinds, at handover.
A morning that goes wrong
Picture the usual case. You open the bedroom window at seven to let the room settle, leave for work at eight, and the sky changes at ten. With a manual window the room takes the rain. With a sensor, the sash closes and you come home to a dry sill. It is a small thing, and it is exactly the kind of small thing a good choice at the start takes care of.
High-ground rule
If the house is empty all day and the window is opened daily, price the rain sensor.
