Is this going to be a permanent trouble causer for the future? All we have been selling over the past year and before is ‘A’ rated windows. I can see in the future a larger proportion of these customers coming back to us to report the same problem. The second problem is going to occur when this feature of energy rated windows becomes openly known to the public, which it will! Is it going to put some potential customers off? The task of selling energy saving windows could be a tad harder from that point onwards.
