136mm Rockwool High-Impact Soffit Slab 1.2m x 600mm

Rockwool High-Impact Soffit Slab is a reinforced stone wool insulation board designed to resist knocks, abrasion, and general wear, making it ideal for high-traffic areas such as car parks and service zones. It delivers the same excellent thermal, acoustic, and fire performance as standard slabs, while the robust facing protects the insulation during installation and everyday use. Its semi-rigid structure allows for a secure fit and durability, ensuring reliable long-term performance even in demanding environments.

Benefits

• Provides strong thermal insulation to help improve energy efficiency and reduce heat loss through exposed soffits
• Euroclass A1 non-combustible stone wool offers top-level fire resistance for safer building design
• Excellent sound absorption helps minimise noise transfer between service areas and occupied spaces
• Factory-applied facings (where used) provide a clean, durable finish suitable for visible applications
• Moisture-resistant and dimensionally stable, ensuring long-lasting performance even in challenging conditions
• Maintains shape and integrity over its lifetime, resisting sagging or deterioration
• Easy to handle and install thanks to its rigid construction and consistent slab dimensions
• Manufactured from natural stone wool containing recycled content, supporting sustainable building practices
  

Good to Know

• Ideal for insulating concrete soffits in car parks, basements, and other exposed ground-floor areas.
• Available in multiple thicknesses to meet different thermal performance requirements
  
• Slabs should be installed in tight formation, with clean edges for a uniform appearance
  
• Easily cut using a utility knife; wear gloves and a dust mask when cutting in unventilated areas
  
• Store under cover, off the ground, avoiding prolonged exposure to sunlight and rain
• Specialist PPE is not required, though a dust mask is recommended if cutting in unventilated areas
