EWI SYSTEM INSULATION
PRODUCT
Coverock® R90
Coverock R90 product is a type of stone mineral wool that is specifically designed for use in External Wall Insulation (EWI) systems. It provides excellent thermal insulation, and once installed, it is well-suited for receiving both hand-applied and machine-applied, mesh-reinforced render systems.
In addition to its EWI applications, Coverock R90 can also be used for internal and external insulation of buildings, providing effective protection against heat loss, noise pollution, and fire protection. Notably, this product is classified as an A1 non-combustible material, which makes it a safe and reliable choice for a range of building insulation needs.
System Compatibility
Fully compatible with all major EWI render systems — including mineral, acrylic, silicone, and polymer-modified coatings.
The stable surface structure ensures optimal adhesion, crack resistance, and a flawless rendered finish.
High Compressive Strength & Dimensional Stability
The robust, fibre-bonded structure ensures long-term mechanical durability.
All products maintain their shape and insulating properties even under high loads, mechanical stress, or thermal fluctuations — ideal for render systems and impact-prone zones.
Application
External Wall Insulation (EWI) systems with mineral or synthetic renders
Solid wall refurbishments and retrofitting of existing buildings
Masonry and concrete façades requiring improved thermal and acoustic performance
Multi-layer façade systems as an outer insulation layer
Thermal and acoustic insulation in service areas, corridors, and internal walls
Fire-safe insulation behind rendered façades in low- and mid-rise buildings
