The salesman explained the product and its benefits very well. The man who came to do the final measurements was very through and professional. The installation was done on schedule and satisfactorily. We have much less outside noise intrusion and are happy with the improved insulation. Would recommend this product to everyone. Not the cheapest product on the market, but once again, you get what you pay for.
