Residential Air Tightness Testing Kits - for domestic air leakage testing

A Retrotec test kit is a flexible and cost-effective solution for domestic air-leakage testing. The fan systems are suitable for testing both houses and flats. Use our equipment calculator to determine the type and number of fans you need.

Please note that under Approved Document L1A, domestic air-tightness testers must either be a registered member of BINDT or work for an organisation which is UKAS accredited. Stroma Technology offers the training required prior to beginning the BINDT registration process. More air tightness testing information.

The Q46 and Q4E make air leakage testing quick, simple and effective. They have a compact and portable design, which simplifies transportation and eliminates vehicle access problems on site. The cloth door kits comprise an easily assembled aluminium frame with extension cams that compress it into the doorway, trapping the cloth membrane in the process and sealing the opening effectively without the need for tape. The Q46 and Q4E are available for either 110V and 230V electrical supply or a combination of the two (3000 series fans only). Both can be left running continuously, a significant benefit for smoke pencil diagnosis.
