Below is a template for you to use in preparing a final, tile specification incorporating tile products marketed under the name Down to Earth®, a product line from Metropolitan Ceramics, manufactured by Ironrock Capital, Inc. This section includes installation materials not manufactured by Metropolitan Ceramics using the reference standard method of specifying.
A typical specification to assure the use of Down to Earth® unglazed textured quarry tile on your next job should be written as follows: |
