I had Burnett come out last summer and replace the siding and 4 windows on my home- i opted for the heavy duty insulated vinyl siding. Their representative said it could withstand 150 mph winds, and to be honest i was skeptical. After recent storms and an EF-3 tornado going through our area, i sustained damage to multiple things on my property, however, my siding was completely unscathed- no cracks, no holes, no loosening- i am 100% impressed with the product and obviously the installation of the product.
