The Cottage is too hot in the Summer heat due to lack of ventilation.
Clear whirlybirds would be great to install in the Cottage to have more sky light as well as ventilating hot air.
It would be ideal to install 3 whirlybirds in The Cottage for heat ventilation (closable for during winter or rain events), which would ideally be clear for extra sunlight in the rooms :)
These are some clear whirlybirds: CSR Edmonds TurboBeam Clear 250mm Natural Roof Vent.
