The updated building regulations have made pressure testing compulsory on all new builds which have an air leakage rate of less than 15m³/m²/hr in there SAP calculations. Due to our aim to provide energy efficient buildings where ever possible we offer testing on all new builds.

Common areas of leakage in traditional builds are

• air leakage through poorly sealed sockets, switches etc. in timber frame walls.
• air leakage at floor zones through wet plastered masonry cavity walls.
• air leakage under skirting boards and through poorly sealed sockets, switches etc. in dry lined masonry cavity walls; and  air leakage through poorly sealed loft hatches and top storey ceiling light fittings.
