We use ultrasound testing to determine air paths in impermeable sections of the building envelope, especially glazing and curtain walling.
It is a vital part of our equipment, if for no other reason than we can eliminate these elements, thus allowing us to concentrate on other items.
Ultrasound readings are not always simple to interpret, so our experienced consultants know how to filter out extraneous sound. We normally combine this with simulated rainfall testing to confirm the problem.
