Ventilation

The build-up of high levels of condensation in the roof space is a big problem that builders need to address. A combination of central heating, double glazing and insulation can cause a temperature differential between living space and the cold air outside. We stock external wall vents, ducting and extraction which all are available online and across our branches in Northern Ireland.
