Tamarack Materials, Inc.

Tamarack Materials is a construction products supplier that serves commercial and residential builders with drywall, steel framing, acoustical ceiling tile, insulation, and related building materials. Drywall and steel studs and tracks are a major focus, with manufacturer lines such as ClarkDietrich, Simpson Strong-Tie, CertainTeed, and Knauf carried for contractors who need specific products.

The company is part of GMS and runs yard locations across several states, including Bismarck, where most stock is available for immediate pickup. Builders can also have materials delivered to the jobsite, and the staff can help match products to a project's fire-rating, acoustic, or R-value requirements.
