We just got a new side door fitted with our chosen pattern which is good, however what concerns me is that the 'leaded pattern is on the outside and open to the elements of our lovely weather. Should it not be internal -on the vacuum side for durability??
Speaking from a window cleaner's point of view - get it on the inside. If it's on the side of your house that gets the weather, it will prob eventually deteriorate ..... plus your window cleaner will hate cleaning it and prob charge you a bit more !!!
Decorative self-adhesive lead can be on the inside or outside. Although it doesn't seem logical to have it exposed to the weather, it's fine if it's good quality and approved with an ISO or a BS number.
