ArmaFlex Ultima Unslit 2m Pipe Insulation

ArmaFlex Ultima Unslit 2m Pipe Insulation is a high-performance, flexible, closed-cell elastomeric foam designed for exceptional fire safety, energy efficiency, and condensation control. Tailored for HVAC, refrigeration, and process equipment, it meets the stringent Euroclass BL-s1,d0 fire safety standard, making it a top choice for commercial, industrial, and residential applications across the UK.

Key Features

• Superior Fire Safety: Powered by patented ArmaPrene technology, it produces 10 times less smoke than standard elastomeric products, enhancing visibility and safety during fire evacuations.
• Low Smoke Emissions: Euroclass BL-s1,d0 rating ensures self-extinguishing properties, no dripping, and minimal flame spread.
• Energy Efficiency: Outstanding thermal conductivity (λd ≤ 0.040 W/(m·K)) minimises energy losses in heating and cooling systems, delivering long-term savings.
• Condensation Control: High water vapour diffusion resistance (μ ≥ 7,000) prevents moisture buildup, reducing corrosion under insulation (CUI) risks.
• Broad Temperature Range: Operates effectively from -50°C to +110°C (down to -200°C for cryogenic applications with technical support).
• Versatile Installation: Offered in 2m unslit tubes with thicknesses of 9mm, 13mm, 19mm, 25mm, and 32mm, fitting pipe diameters from 6mm to 114mm.
• Eco-Friendly: Free of bromine, antimony, and PVC, complying with LEED, BREEAM, and DGNB standards. Low VOC emissions support excellent indoor air quality.

Applications

ArmaFlex Ultima is ideal for insulating pipes in:

• Heating, ventilation, and air conditioning (HVAC) systems
• Refrigeration units
• Industrial process equipment
• Commercial and residential buildings
• London Underground projects (LUL-approved)

It offers robust protection for elbows, fittings, and flanges, forming a cohesive insulation system when used with ArmaFlex Ultima 700 or EC0550 adhesives and ArmaFix Ultima pipe hangers.

Installation and Compatibility

For best results, pair ArmaFlex Ultima with:

• Adhesives: ArmaFlex Ultima 700 (1.0L cans) or EC0550 (solvent-free, 300g tins) for strong adhesion.
• Pipe Supports: ArmaFix Ultima pipe hangers to eliminate thermal bridging.
• Tape: ArmaFlex Ultima tape (3mm x 50mm x 15m) for enhanced sealing.
• Cleaners: ArmaFlex Cleaner or solvent-free SF-Cleaner for surface preparation.

Outdoor installations require UV protection (refer to Armacell Technical Bulletin no. 142). Store in dry, clean environments at 50–70% humidity and 0°C to 35°C.
