Open-Cell vs Closed-Cell Spray Foam

Both open-cell and closed-cell spray foam insulate and air-seal. They differ in thermal resistance per inch, vapor behavior, the space they need and how they are typically used, so neither is the universal answer for every Michiana assembly.

A Simple Way to Start

  1. Identify the spaceattic, crawlspace, basement, rim joist, wall, pole barn, garage or commercial area.
  2. Check moisture and ventilation first, because those conditions affect assembly suitability.
  3. Compare material and assembly options for that space rather than choosing a foam type in isolation.
  4. Prepare a written scope and estimate request with surfaces, access, current insulation and timing.
