It is a common misunderstanding that metal windows or Rooflights and Condensation are the cause of condensation problems.

‘Condensation is the water which results from the conversion of water vapour in the atmosphere’.

The increased incidence of condensation in today’s buildings is the direct result of changes in modern living conditions, which have led to warmer and more comfortable rooms. In many homes, traditional open fires have been replaced by sophisticated heating systems, ill fitting doors and window frames have been provided with draught excluders, floors have been completely covered by fitted carpets, while ceiling heights have been lowered and the space between loft joists filled with insulating material.

These modern aids to home comfort have created rooms which are warmer but which often have less ventilation and fewer air changes. The result is that the water vapour produced by normal living activities is no longer able to escape. In certain circumstances, all these aids to comfort combine to create ideal conditions for the formation of condensation.

The question is how to How to Reduce Condensation without sacrificing the benefit of increased comfort.

One way to help alleviate condensation on skylights is to have an opening version to allow air to pass across the face of the casement. This small change will make a big difference. NuDawn skylights use a high specification of glazing to assist with the thermal performance and any condensation that occurs on the glass will indicate high moisture content in the room.

When double glazing is used in conjunction with heating and Controlled Ventilation Considerations with Condensation, it helps solve the problem.
