How Big Is The Condensation Problem Going To Be?

We had another couple of customers contact us today regarding condensation on their new windows. Luckily, after explaining the physics of the problem they understood and the matter went no further. But as we all know, customers in this industry can sometimes be a royal pain in the backside over things like this.

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.
