This guide provides a step-by-step installation process, alongside addressing frequently asked questions to ensure a seamless and efficient installation.


  1. Surface Preparation: Begin with a clean, dry pipe. It's crucial to remove any debris, dust, or moisture to ensure the insulation adheres properly. Accurate measurement of the pipe lengths is essential for a precise fit, minimizing waste and ensuring optimal insulation performance.

Cutting to Size

  1. Measuring and Marking: Use a tape measure to determine the required length of the Rockwool RWA45 slab. Mark the measurement clearly on the insulation material.
  2. Cutting: With a fine-tooth saw or a sharp knife, cut the Rockwool slab according to the marked measurements. Ensure the cut is clean and straight to maintain the integrity of the insulation material.

Applying Insulation

  1. Opening the Insulation Slab: Carefully open the Rockwool slab along its slit side. This design is specifically made for easy application around pipes or structures.
  2. Placement: Encase the pipe with the insulation slab, ensuring a snug fit around the circumference. A proper fit is crucial to prevent thermal bridging, enhancing the insulation's effectiveness.

Securing Insulation

  1. Sealing Seams: Use adhesive or special insulation tape to securely seal the seams between sections of the insulation. This step is vital in maximizing the insulation's efficiency by preventing heat loss and moisture ingress.

Finishing Touches

  1. Waterproofing: For pipes or installations exposed to moisture or outdoor conditions, apply a waterproof finish or cladding over the insulation. This protects the Rockwool material from water damage and prolongs its lifespan.
