In today’s energy conscious society, one of the major problems faced by builders is the build up of high levels of condensation in the roof space. Widespread use of central heating, double glazing and insulation can cause a temperature differential between living space and the cold air outside. Warm air, carrying high levels of water vapour, is drawn by a process of convection to cold areas of the building including the roof void. If there is insufficient ventilation the water vapour condenses, leading to rotting timbers, the rusting of metal fixtures, felt damage and mould growth.
To solve this costly problem, Manthorpe manufactures a range of quality roof ventilation products which are suitable for new build and refurbishment situations.
