Your house may have the older type of glazing which are not as efficient as the more modern variants and fail to perform to the higher specification require by the emerging energy aware consumers.
So what are the obvious signs of a failed glazing unit? Inspect your window to see if you can spot the following factors that indicate an ineffective sealed glass unit:
