ACH-R20/1-07-GY Arma-Chek R - 1mm CSM (CSPE) Covering Sheet for Insulation Protection
ACH-R20/1-07-GY is a specific variant of Arma-Chek R: a high-performance, flexible non-metallic covering sheet (1mm thick, 0.7m wide x 20m long, grey) engineered to protect elastomeric and other insulation materials from harsh environmental factors. Formulated with CSM (CSPE) polymer, this durable cladding excels in offshore, heavy industry, chemical, and petrochemical settings across the UK, offering resistance to salt water, UV radiation, mechanical impact, and ozone while minimising corrosion under insulation (CUI).
Key Benefits
- Weather & UV Protection: Excellent resistance to UV attack, rain, frost, salt water, and chemicals; fully weatherproof without additional jacketing.
- Mechanical Durability: High tensile strength (≥4.5 MPa), tear strength (≥7.0 N/mm), and puncture resistance (104.44 N for 1mm) for impact-prone environments.
- Corrosion Mitigation: Low leachable chlorides and ammonia ions (≤100 ppm) to prevent CUI.
- Water Vapour Barrier: In-built barrier with μ ≥ 50,000 and permeability ≤ 3.91 x 10⁻¹² g/(m·s·Pa) to block moisture ingress.
- Fire Safety: BS 476 Part 6 Class 0 & Part 7 Class 1; IMO FTP Code Parts 2 & 5 certified for low smoke, toxicity, and flammability.
- Acoustic Enhancement: Natural dampening complies with ISO 15665 Classes A-C and Shell DEP for re-radiation noise reduction.
- Flexible & Compatible: Expands/contracts with Armaflex insulation; easy to cut and install on pipes, ducts, and vessels.

Applications
ACH-R20/1-07-GY is tailored for UK industrial projects, protecting insulation on:
- Pipework, fittings, vessels, and equipment in offshore/marine environments
- HVAC ducts and process lines in chemical/petrochemical plants
- Exposed installations vulnerable to salt water, UV, or mechanical damage
- Acoustic systems for noise control (ISO 15665 compliant)
- Heavy industry setups requiring low-maintenance, CUI-resistant cladding
Installation Guidelines
Bond using Armaflex Adhesive 520, HT625, or Ultima 700; ensure minimum overlap. Seal joints with Arma-Chek Mastic for a vapour-tight finish. Apply at +5°C to +35°C (max 80% RH). Slight aesthetic wrinkling may occur due to temperature fluctuations, but it does not affect performance. Please consult the installation manual for further information. Shelf life: 3 years stored indoors, dry, away from sunlight/ground.
