Many thanks for your team’s great work. It was efficiently done with minimal disruption apart from moving a bit of furniture around. We have noted an immediate drop in temperature during the day to our north facing front bedroom that gets full sun. It use to feel like a furnace on entering it during the day & it is so much more pleasant to enter during the night to go bed. The house overall is very stable in temperature and even with cooler autumn temperatures overnight the house temperature does not drop overnight.
