What’s going on in there?

Once you’ve seen the performance of your walls using the thermal imaging camera, your cavity walls efficiency and contents may need investigated. One way we can investigate this is using the borescope camera to capture images within the cavity. This involves drilling a 10mm hole in the exterior wall in each area under investigation, then inserting the camera.

(this image shows some blown fibre, but plenty of voids meaning a poor fill, leading to poor efficiency.)
