Internal Wall Insulation | Interior Walls

Internal wall insulation products are vital components in any construction or renovation project, serving to protect buildings from energy loss and aid in energy conservation. The Insulation4us internal wall insulation category boasts an extensive range of high-quality insulation products from reputable brands like Owens Corning, Rockwool, Hunter Panels, Knauf, and Kingspan, designed to meet diverse needs and applications.

Fiberglass Insulation

Owens Corning offers a vast array of fiberglass insulation products such as R-21 Kraft Faced, R-15 Unfaced, and R-30 Unfaced Fiberglass Insulation Batts. These batts are available in varying sizes and are renowned for their thermal performance, contributing to energy efficiency and comfort in residential and commercial buildings. They are versatile and can be used in various parts of a building including walls, attics, and basements.

Rockwool Insulation

Rockwool products, like the Rockwool Comfortbatt R15 and Rockwool AFB (Acoustic Fire Batt), are celebrated for their fire-resistant and soundproofing properties. These are suitable for internal walls where acoustic control and fire resistance are crucial. They are typically applied in commercial buildings, studios, and residences where noise reduction is a priority.

Polyiso Panels

Hunter Panels’ Xci Foil Polyiso Panels and other variations like XCI Ply and XCI Concast are recognized for their exceptional R-values and moisture resistance. These are ideal for locations prone to moisture and where high thermal resistance is essential. Polyiso panels are often used in external walls but are also suitable for internal walls requiring additional insulation.

Loosefill Insulation

Owens Corning’s PROPINK L77 PINK Fiberglas Unbonded Loosefill Insulation is essential for filling gaps and voids, preventing air leakage and enhancing thermal performance. This is especially practical in irregularly shaped areas where traditional insulation might not fit, ensuring no space is left uninsulated.

Blowing Wool Insulation

Knauf offers products like Jetstream Ultra Blowing Wool and Ecofill WX Blowing Wool designed for optimal thermal and acoustical performance. These are conducive for application in attics, walls, and hard-to-reach areas due to their loose-fill nature, providing comprehensive coverage and improved energy efficiency.

 

Choosing the Appropriate Insulation

When selecting internal wall insulation, consider the specific needs of your project:

  • Thermal Performance: Choose products with the appropriate R-values, representing the material’s resistance to heat flow, based on the climate and the building's specific requirements.
  • Acoustic Control: For areas where noise reduction is essential, consider insulation products with excellent soundproofing properties, such as Rockwool AFB or Thermafiber Sound Attenuation Fire Blankets.
  • Fire Resistance: Consider fire-resistant products like Rockwool insulations for areas where fire safety is a priority.
  • Moisture Resistance: For areas prone to moisture, like bathrooms and basements, select water-resistant products like Polyiso panels or specialized insulation boards from Kingspan.
