  • 2004 BRE test at Wymott Prison – 80% reduction in air changes which equated to a 25% energy saving
  • BRE for EEC2, (later CERT) on domestic properties which showed 2.3 times the energy saving of traditional methods


Salix – Many of our clients have used Salix to fund their energy saving projects since its inception.

With the transformation in the market we are now being tagged into many decarbonisation schemes where Quattro Seal has been used to bring down the cost on what it costs to save a tonne of carbon.
