'Heat and moisture in roof spaces can affect personal comfort levels in the home and the condition of roof timbers.'

HEAT

During summer months temperatures in roof spaces can reach as high as 60°c.This heat radiates downwards causing discomfort in living areas and forcing air conditioners to work harder. Even the effectiveness of ceiling insulation can be reduced by the additional heat load.

MOISTURE

During the colder months, water vapour from showers and cooking is drawn into roof spaces and can condense to form up to 12 litres of moisture per day. This can render insulation ineffective, cause mildew on walls and ceilings and contribute to a damp environment.

Winter WITHOUT VENTILATION, MOISTURE LADEN AIR RISE AND CONDENSES IN ROOF SPACE. DAMPNESS IS TRAPPED.	Summer WITHOUT VENTILATION, HEAT FROM THE ROOF SPACE RADIATES INTO HOME AND CAN ALSO LIMIT THE EFFECTIVENESS OF INSULATION.
