We manufacture premium-quality insulation, commercial roofing and fibers and nonwovens for commercial, industrial and residential applications.

We are excited to announce the introduction of DensDeck® StormX™ Prime Roof Board, a single ply system that offers better protection from the elements. In combination with JM TPO 60 mil over a steel deck, this cover board achieves a Very Severe Hail rating.

In 2018, our Engineered Products team started a partnership with ultra-runner Andrea Low to demonstrate the #JMextraMile. Now it's our employees turn to share their achievements. Visit the new JM Athletes page to discover what going the extra mile means to them.
