Why Highlands homeowners are upgrading their windows
Highlands took 885mm of rain and 45 frost days in 2025. Those freeze / thaw cycles lift seals, warp frames and let moisture creep in behind older glazing. The county also carries 4,089 listed buildings on the National Heritage List. On those homes a full window replacement is not an option and secondary glazing is usually the route.
