From Alaska to the Caribbean Islands and from Maine to Mexico, hundreds of millions of square feet of BondCote roofing have been installed since we began making the only NBP (nitrile butadiene polymer) thermoplastic roof membrane available in 1977. By the way, there still are no others. In nearly thirty years of punishing exposure, we've never failed to live up to our promises and our standards. And, it turns out that our NBP (nitrile butadiene polymer) design of thermoplastic membranes was right on. Look at our track record in varying environments. That's why we haven't developed other thermoplastic formulations; we just don't see the need. Combining high reflectivity and high emittance, BondCote helps to lower HVAC costs while built-in biocides inhibit mildew, fungi and algae growth, thus retaining those properties over a longer period. Our track record of over 30 years of successful roof installations evidences our commitment to the commercial roofing industry.
