Overheating in residential towers and apartment blocks.

03 · How it works

1

Desktop review

Send us the address. We measure the glazing off scaled plans or satellite imagery and model the building. You get a written energy review. It costs you nothing and commits you to nothing.
2

Site survey and baseline readings

If the numbers are worth pursuing, we visit, record the glazing schedule and take calibrated readings at the glass. That baseline is what we measure against afterwards.
3

Application, in stages, building in use

Our accredited regional installers apply the coating internally by roller. No scaffolding. No external access. We phase the work around your timetable.
