Guidelines for Handling, Cutting, and Storage

1. Position 75mm XO/CW on a flat, clean base away from ground contact, keeping it covered and protected from weather.
2. Note that polythene wrapping alone does not provide adequate protection for the insulation against exposure to the elements.
3. Take care to shield the Partial Fill insulation Board during both storage and on-site handling.
4. Always use suitable Personal Protective Equipment (PPE) when working with the insulation.
