The R-value, a measure of thermal resistance, is a key factor in determining the effectiveness of cavity wall insulation. Generally, the R-value varies depending on the type of insulation material used.

For example, materials like Rockwool or Knauf OmniFit slabs, available from Workplace Interior Shop, typically have R-values that range from 3.0 to 3.5 per inch of thickness. This means they provide a high level of thermal resistance, effectively slowing down the transfer of heat through the walls of your property.

It’s important to choose insulation with an appropriate R-value for your specific needs. The higher the R-value, the greater the insulation’s effectiveness in preventing heat loss. Our experts at Workplace Interior Shop can assist you in selecting the right insulation product with the optimal R-value for your building, ensuring maximum energy efficiency and comfort.
