The MVHR Experts

To meet current building regulations new buildings have become more air tight and highly insulated, this can cause new problems such as high humidity, mould growth and bad air quality, this creates a need for ventilation. Unlike common extract fans MVHR not only takes away the stale air from your home and replaces it with fresh air but it recovers the heat in the air before it is exhausted outside and heats the incoming air which is introduced into the building. 

We supply one of the best performing heat recovery products on the market which incorporates very sophisticated technology and enables an outstanding 93% heat transfer.
