    I own a business plaza of about 6000 square feet and needed a high quality product as it is in a high fire zone in Ca. They were easy to deal with and responded to my email promptly with the information I needed. The product was easy to apply on the wood siding and actually improved the look of the building. National Fireproofing Supply Co. supplied me with the highest quality products available.

    I highly recommend National Fireproofing Supply.
