Guiding Your Selection

• Efficient Thermal Management: Identify the R-value suitable for your geographical and structural conditions to optimize thermal performance.
• Acoustic Control: Choose products with emphasized sound attenuation properties where noise management is pivotal, such as in residential areas or office spaces.
• Fire Resistance: In environments or structures where fire safety is a prominent concern, prioritize products that proffer enhanced fire-resistant properties.
• Application-Specific: Understand and align the product’s specialized functionalities (like curtain wall applications) with your specific project needs.

Benefits of Mineral Wool Insulation

• Non-combustible & fire-safe – Withstands temperatures above 2000°F, adding crucial fire protection to your building.
• Excellent thermal efficiency – Delivers stable R-values across a range of climates.
• Superior sound absorption – Dense structure reduces airborne noise and improves acoustic comfort.
• Moisture & mould resistant – Inorganic fibres do not absorb water or promote mould growth.
• Dimensional stability – Maintains shape and performance over time without sagging or settling.
• Eco-friendly – Made with a high percentage of recycled content.

Applications of Mineral Wool

• Exterior walls – Thermal and fire protection in residential and commercial walls.
• Interior partitions – Acoustic insulation for bedrooms, offices, and media rooms.
• Floor & ceiling assemblies – Reduce sound transmission and improve energy efficiency.
• Basements – Moisture-resistant insulation for below-grade walls.
• Curtain wall & cavity systems – For high-rise and commercial façade fire safety and thermal performance.

Guidance on the Selection of Mineral Wool

• Match R-value to climate zone – Colder climates require higher R-values (e.g., R-23, R-30) for maximum efficiency.
• Consider the purpose – For sound control, choose acoustic-focused products like Safe’n’Sound or SAFB. For thermal performance, select Comfortbatt or UltraBatt.
• Check stud cavity depth – Ensure thickness aligns with your wall or floor framing.
• Select the right format – Batts for standard framing, boards for curtain wall, or continuous insulation.

Installation Tips

• Measure stud or joist spacing and cut batts slightly oversized for a friction-fit.
• Use a serrated knife or insulation saw for clean, accurate cuts.
• Fit insulation snugly, filling the full depth of the cavity without compression.
• For pipes or electrical boxes, notch the batt and seal around edges to prevent gaps.
• Always wear gloves, long sleeves, and safety glasses when handling mineral wool.
