There are a number of reasons. To start with, finding a suitable, proven ventilation unit with the right size to fit into most underfloor insulation situations might prove difficult. Furthermore, whatever unit you choose has to prove the requisite number of airflow changes per hour as will be specified in the upcoming amendment to the BEIS Guidance on Underfloor Insulation. Our MEV ECO product provides the technical characteristics required to fulfil the requirements of Building Regulations – Part F and therefore PA2030: 2019. Buying a unit in the hope that it will work is probably not going to get any fails overturned.
What we’re selling is a complete turnkey solution supported by a Trustmark Scheme provider, professional ventilation design experts, a 10 year warranty, an Insurance Backed Guarantee and lodged by a Retrofit Coordinator. It’s a complete solution rather than installing a ventilation device and hoping for the best.
