In 1979, Joe Novogratz founded IDI with a mission: build an insulation distribution company that would supply the market with a wide selection of quality insulation and act as a true, professional resource for independent contractors. Over 45 years later, IDI is still family owned, and has helped over 3,000 independent insulation contractors successfully grow their businesses nationwide. When you need a great contractor or if you want to become one, reach out to your local branch or anyone at IDI.
