Armaflex Sheet Rolls

The Complete Guide to Armaflex Sheet Rolls in the UK

Armaflex sheet rolls provide high-performance insulation for ductwork, pipework, refrigeration, and hot and cold water systems in the UK. Manufactured by Armacell, these flexible elastomeric sheets offer superior condensation control, corrosion resistance, and thermal efficiency.

What is Armaflex Sheet Insulation?

Armaflex sheet insulation is made from closed-cell elastomeric nitrile rubber foam, designed to control condensation and reduce the risk of corrosion under insulation (CUI). Available in flat sheets and rolls, the insulation is ideal for air conditioning ductwork, pipe lagging, and chilled water systems. The product is known for its low thermal conductivity and high resistance to water vapour transmission.

Key Benefits of Armaflex Sheet Rolls

• Condensation Control – Armaflex® Class O roll is specifically designed to control condensation and prevent moisture ingress.

• Corrosion Prevention – The vapour barrier and closed-cell structure significantly reduce the risk of corrosion under insulation.

• Energy Efficiency – By minimising energy losses, Armaflex sheet insulation improves the overall efficiency of HVAC systems.

• Fire Performance – Armaflex Class O sheet offers excellent fire performance, making it suitable for use in public buildings and process industries.

• Antimicrobial Protection – Built-in Microban® antimicrobial protection prevents the growth of mould and bacteria.

• Versatility – Suitable for a wide range of applications, including hot and cold water systems, refrigeration, and air conditioning ductwork.

• Ease of Installation – Self-adhesive backing allows for quick and easy installation, reducing labour costs.

Applications of Armaflex Sheet Rolls

• Ductwork Insulation – Flat sheet insulation is ideal for insulating air conditioning ductwork and preventing condensation.

• Pipe Lagging – Armaflex sheets can be cut to size for pipework insulation in hot and cold water systems.

• Refrigeration – Armaflex Class O nitrile foam is highly effective at preventing condensation in chilled water and refrigeration systems.

• Industrial and Commercial Use – Used extensively in public buildings, process industries, and industrial applications.

Installation Process

1. Clean the Surface – Ensure the surface is free from dust and debris.

2. Cut to Size – Use a sharp knife to cut the Armaflex sheet to the required size.

3. Apply Armaflex Adhesive – For non-self-adhesive sheets, apply Armaflex adhesive to the surface.

4. Wrap or Lay the Sheet – Apply the sheet around pipework or ductwork, ensuring full coverage.

5. Seal the Joints – Use self-adhesive backing or tape to ensure airtight seals.

6. Inspect and Maintain – Regularly inspect for any damage and ensure the insulation remains intact.

Conclusion

Armaflex sheet rolls provide an effective insulation solution for a variety of applications, from ductwork to pipe lagging and refrigeration systems. With built-in vapour barriers, antimicrobial protection, and excellent fire performance, Armaflex insulation ensures long-lasting energy efficiency and corrosion resistance.
