I’ve noticed a difference already, we’ve needed hardly any heating.
The teams of craftsmen restored, draught proofed and fitted secondary glazing, CozyGlazing, to ten sash windows and two doors. When they arrived in the summer they set up their machinery in the garage and got started. The works took about three weeks. Kai and his men were a pleasure to have about the place. I’ve noticed a difference already, we’ve needed hardly any heating, and it’s mid October. Great stuff!
