Airtightness Details installed On Site

19.10.2019 - FmK visit one of our clients to perform our Intermediate Blower Door test, were we pressurize the house after all the air tightness materials have been applied but before internal finishes such as plastering is completed. This enables us to find any imperfections in the applying of the tapes or membranes and so achieve a better final result. You can also see the use of Blowerproof paint on air tightness membrane which has proved very sucessful in those awkward areas. Below are a range of typical junctions that had been prepared for this test.
