EWI SYSTEM INSULATION
PRODUCT
COVERSLAB® R
Coverslab® R is a robust stone mineral wool insulation board specifically developed for External Wall Insulation (EWI) systems.
It delivers excellent thermal efficiency, mechanical strength, and fire resistance, making it ideal for both new-build and refurbishment projects.
With a declared thermal conductivity of λD = 0.035 W/m·K,
Coverslab® R ensures superior thermal comfort and energy savings while maintaining outstanding vapor permeability for a healthy building envelope.
Its dense, resilient structure provides strong adhesion for base coats and renders, ensuring long-term durability and surface stability.
Fully Euroclass A1 non-combustible, Coverslab® R offers reliable fire protection and contributes to the safety and performance of external wall systems.
Manufactured in 1200 × 600mm format, it is perfectly suited for modern EWI applications — combining strength, efficiency, and sustainability in one dependable insulation solution.
Excellent thermal insulation performance
(λD = 0.035 W/m·K)
Provides outstanding thermal efficiency, minimizing heat loss and ensuring stable indoor comfort throughout the year.
Vapor-Permeable Yet Hydrophobic
Allows walls to “breathe” while preventing water penetration.
This ensures that moisture does not accumulate within the insulation system, maintaining the integrity of both the insulation and render layers over time.
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
