CMI is the expert in combining the industries best fiberglass with the best facings. Our standard faced fiberglass insulation product line for metal buildings includes 2” (R7), 3” (R10), 3½” (R11), 4” (R13), 6” (R19), 8” (R25), and 9” (R30). Higher R-values can be achieved by layering additional un-faced insulation on top of faced insulation of a lower R-Value. Our large varieties of reinforced vapor barriers are strong, attractive, and wrinkle free. Not only do our vapor barriers provide condensation control, but provide an overall attractive interior finish which also enhances light reflectivity.

Our insulation is “Formaldehyde Free” which makes it white in color, dust free, itch free, odor free, and incredibly user friendly. In fact, Johns Manville Fiberglass has been touted as the most user friendly blanket in the industry by professionals who install on a day to day basis. It is easy to install, will not rot or decompose, is fire resistant, and offers excellent sound control properties. Our various systems of installation allow the insulation to be applied in single or multiple layers to give you the thermal performance you need. This type of faced insulation is most commonly installed over or within the structural frame of the building; inside the wall and roof sheets.

Insulation properly selected and professionally installed will give more returns on your investment than any other building component.

Benefits of Metal Building Insulation

Controls Heat flow

Metal building insulation acts as a barrier to slow down the movement of heat, keeping it inside the building in winter and outside the building in summer. By controlling the rate of heat transfer through the building, insulation reduces energy consumption, resulting in lower fuel bills and a cleaner environment.

Prevents Condensation

Metal building insulation faced with a vapor barrier, limits the passage of water vapor and prevents it from condensing within the insulation or on the interior surfaces of the building.

Controls Noise

Metal building insulation greatly reduces the level of both exterior and interior noise by preventing transmission of exterior sounds to the interior of the building and absorbing reverberating sounds within the building.

Increases Lighting Efficiency

The laminated facings on metal building insulation provide a bright, attractive wall and ceiling treatment that acts as a reflector to increase lighting efficiency.
