How Is Cavity Wall Insulation Installed?

Installation of cavity wall insulation in Hardwick begins with a comprehensive home survey to assess cavity condition, wall type, and ventilation needs. We then prepare the site by clearing obstacles and marking injection points.

Small holes are drilled through mortar lines, and the chosen insulation material is injected using specialist equipment. After filling, the holes are sealed, and the area is cleaned up. A post-installation check follows using thermal imaging or visual inspection to confirm full cavity coverage.
