130mm Rockwool Soffit Slab (Plain) 1m x 600mm

Rockwool Soffit Slab (Plain) is a rigid stone wool insulation board designed to deliver thermal efficiency, fire protection, and acoustic comfort in exposed soffit areas. Its plain construction is ideal for car parks, basements, and other ground-floor concrete soffits where a decorative or protective facing is not required. The plain slab can be painted or finished on-site if needed, while maintaining shape, density, and long-term insulation performance. Its semi-rigid design ensures a secure fit and easy handling during installation.

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
