2. Product Overview and Features
ProRox SL940 mineral wool boards are engineered for durability and performance in demanding environments. Key features include:
- Noise Insulation: High density and random fiber orientation effectively trap sound waves, reducing noise transmission and vibration. Ideal for offices, bedrooms, and areas requiring sound control.
- Thermal Insulation: Provides superior thermal resistance (R-value) compared to many traditional insulation materials, contributing to energy efficiency and reduced heating/cooling costs.
- Fire Resistant: Composed of rock, the material is inherently fire resistant, meeting properties in accordance with ASTM C553. This enhances building safety.
- Water Resistant: The boards do not absorb water or retain moisture, featuring characteristics that drain water away, preventing mold and mildew growth.
- Long-Term Performance: The inherent durability of stone wool ensures an extended product lifetime without significant degradation.
- Ease of Installation: Designed for straightforward cutting with a serrated knife, allowing for clean edges and a precise fit during installation.

3. Safety Information
Always prioritize safety when handling and installing insulation materials.
- Personal Protective Equipment (PPE): Wear appropriate PPE, including safety glasses, gloves, and a dust mask or respirator, to prevent skin irritation and inhalation of airborne fibers.
- Ventilation: Ensure adequate ventilation in the work area to minimize dust accumulation.
- Handling: While durable, handle boards carefully to avoid unnecessary breakage or damage.
- Cutting: Use a sharp serrated knife or specialized insulation saw for cutting. Cut on a stable surface away from sensitive materials.
- Disposal: Dispose of waste material according to local regulations.

4. Installation Instructions
Follow these steps for effective installation of ProRox SL940 mineral wool boards:
- Preparation: Ensure the installation area is clean, dry, and free from obstructions. Measure the dimensions of the cavities or surfaces where the insulation will be installed.
- Cutting: Using a serrated knife or insulation saw, carefully cut the ProRox SL940 boards to the required size. Cut slightly larger than the cavity width (approximately 1/2 inch) to ensure a snug, friction fit.

- Fitting: Gently compress the cut board and insert it into the wall, ceiling, or floor cavity. The board should fit snugly without gaps. Ensure the insulation is flush with the framing members.
- Obstructions: Carefully cut and fit insulation around electrical boxes, pipes, and other obstructions to maintain continuous coverage.
- Vapor Barrier (if required): If a vapor barrier is necessary for your climate zone, install it according to local building codes after the insulation is in place.
5. Maintenance
ProRox SL940 mineral wool boards require minimal maintenance once installed.
- Inspection: Periodically inspect exposed insulation for any signs of damage or moisture intrusion. Address any issues promptly.
- Moisture: Although water-resistant, prolonged exposure to standing water should be avoided. Ensure proper drainage and waterproofing in areas where insulation is installed.
- Cleaning: If necessary, gently clean any surface dust with a vacuum cleaner or soft brush. Avoid using harsh chemicals or excessive moisture.

7. Troubleshooting
Mineral wool insulation is generally straightforward to install and maintain. However, consider the following if issues arise:
- Gaps in Insulation: Ensure boards are cut slightly oversized for a friction fit. Fill any small gaps with cut pieces of insulation or appropriate sealant to maintain thermal and acoustic performance.
- Moisture Accumulation: If moisture is observed, identify and address the source of water intrusion immediately. Remove and replace any insulation that has become saturated to prevent mold growth and maintain performance.
- Dust and Irritation: If experiencing excessive dust or skin irritation during handling, verify that appropriate PPE (dust mask, gloves, long sleeves) is being used and that the work area is well-ventilated.
