Wall & Floor Ventilation

Ventilation products designed to provide airflow into the underfloor void which, if left unventilated, can be a breeding ground for mould and stagnant air.

The underfloor void, if left unventilated, can be a breeding ground for mould and a collection point for stagnant – and potentially explosive gases. Part C of the Building Regulations stipulates the use of through wall and underfloor ventilation to combat these problems and ensure that the areas surrounding and below a property are adequately ventilated.

The problem is easily solved with Manthorpe’s range of ventilation products – which has the double advantage of being both quick and easy to install.
