Exterior Wall
Enhance energy efficiency
Outside walls are where heat loss or heat penetration most commonly occurs in the majority of buildings. Exterior wall insulation can significantly moderate this, improving the building’s energy efficiency, cutting CO2 emissions and reducing fuel or cooling costs.
Benefits
-
Resists heat transfer, increasing energy efficiency -
Noncombustible products can slow the spread of fire -
High density effectively reduces sound transmission -
Increased drying potential – reduced risk of moisture accumulation
Application
Interior Insulated
(Stud Cavity)
Interior-insulated assemblies can achieve improved thermal performance by using ROCKWOOL Comfortbatt within the stud cavity as the higher-density batts reduce airflow within the wall cavity, thereby reducing convective losses.

Application
Split Insulated
Split-insulated assemblies capitalize on the existing thickness of the stud cavity by using stud cavity insulation. With the addition of continuous exterior insulation, the assembly can achieve improved thermal resistance and fire and acoustic targets while optimizing wall thickness.

FAQ
Will external wall insulation stop condensation?
External wall insulation can help prevent moisture from forming on walls as a result of condensation. However, it’s important you fix any problems related to burst guttering, roof problems or rising damp as well.
How long does external wall insulation last?
Good external wall insulation should last for decades, provided it is installed properly. You can expect it to last longer when it is made from highly durable material. ROCKWOOL insulation can maintain its performance for the lifetime of a building.
