Johns Manville Unfaced Insulation presents a versatile range of fiberglass insulation batts designed to meet varying needs and applications, ensuring high-performance thermal and acoustical insulation. These products, suitable for both wood and steel framing, are available in various sizes and R-values, catering to diverse project requirements.

Practical Uses:

Johns Manville Unfaced Insulations are ideal for improving energy efficiency and sound control in residential and commercial buildings. They are typically installed in walls, ceilings, floors, and attics, assisting in maintaining a comfortable indoor environment by reducing heat transfer and mitigating noise levels.

  • High R-value Insulation (R-25 to R-30): Suitable for colder climates and areas in a building requiring enhanced thermal protection. R-30 and R-25 insulations are perfect for spaces like attics and exterior walls where higher thermal resistance is critical.

     

  • Medium R-value Insulation (R-19 to R-21): These are versatile insulations used widely in both exterior and interior walls, floors, and ceilings, providing a balanced thermal barrier suitable for varied climates.

     

  • Low R-value Insulation (R-11 to R-15): Ideal for interior walls and spaces where basic insulation is required. They are optimal for moderate climates and spaces like basements and interior walls, contributing to overall comfort and energy efficiency.

     

Guidance on Selection:

  1. Identify the Framing: Choose the insulation based on whether the application involves wood or steel framing. Johns Manville offers specialized products tailored for each framing type.

     

  2. Determine the R-value Needed: Consider the climatic conditions, the area of application within the building, and local building codes to select the appropriate R-value. Higher R-values are ideal for colder climates and areas requiring superior insulation.

     

  3. Measure the Space: The available sizes are suitable for diverse spacing needs. Measure the space accurately to select the right size of insulation batt, ensuring a snug fit.

     

  4. Consider Acoustic Needs: If sound control is a priority, choose insulation with superior acoustic properties to minimize noise transfer between spaces.
