Will I lose heat in the winter?

mouldy roof

A damp roof is a cold roof and a dry roof is a warm roof. Roof Ventilators are a great aid in the prevention of damp roofs' caused by snow or cold air loaded with moisture.

Twista Roof Ventilators work efficiently even in the winter as they help keep the roof cavity dry of moisture and condensation caused from bathroom fans and cold frosts, thus avoiding mould and mildew that can grow onto ceilings. Also, during the winter months your ceiling insulation acts as a barrier to keep heat within the room, and moisture on your insulation reduces it's effectiveness.
