Ventilation in housebuilding is changing. The continued drive to improve the energy efficiency of our homes means buildings are becoming increasingly air tight and thermally efficient. This makes it more important than ever before to ventilate effectively. Housebuilders are therefore looking for a ventilation solution that saves energy, reduces carbon emissions and provides good indoor air quality (IAQ). With MVHR ticking all the right boxes it is no surprise that the industry volume is 50,000 units a year and still growing, with it set to dominate ventilation in most new homes.
