ISP Minerals is changing its name to Specialty Granules Inc.  The new name, Specialty Granules, reflects our long time commitment to supplying high quality granules to the North American Roofing industry.  For over 85 years our company has provided a high level of service and high quality products to the roofing industry.

Beyond the name, nothing else changes.  Specialty Granules will provide the same high levels of personalized service from the same great people, the same reliable plants, the same dedicated managers and the same committed owners.  It is our expectation to be even better tomorrow than we are today.  We continue to strive to provide cutting edge products to meet the roofing industry needs.  We are currently expanding our Annapolis Missouri Plant to have greater capacity to serve industry growth.  We stress continuous improvement in everything that we do to be the best possible supplier we can be.  Maintaining a safe workplace for our employees and being a good steward to the environment have been and will continue to be a mainstay in our culture.  Our employees, our vendors and the communities that we operate in have been critical to our success and will continue to be critical to our future.  We are proud to be an American manufacturing company.

If we can help you in any way, please contact us.  We look forward to working beside you in the future.
