Armaflex HT Solar Pipe Insulation 2m Outdoor High Temperature UV Resistant

Armaflex HT Solar Pipe Insulation – 2m Outdoor High-Temperature UV Resistant

Protect your outdoor pipework with Armaflex HT Solar Pipe Insulation, a high-performance solution engineered for extreme temperatures and harsh outdoor conditions. Manufactured from flexible elastomeric EPDM foam in accordance with EN 14304, it is rated for continuous service up to +150°C with exceptional UV resistance. Available in 10mm, 13mm, 19mm, and 25mm wall thicknesses for pipe sizes from 10mm to 89mm — the specified choice for solar collectors, HVAC systems, hot gas lines, and heat pump pipework.

Key Features & Benefits

• Superior UV Resistance: EPDM foam rubber withstands UV radiation and weathering without cracking or crumbling, providing long-term protection without additional painting or cladding in standard outdoor conditions.
• High Temperature Rated: Full service temperature range of -50°C to +150°C — suitable for solar heating, hot gas lines, and steam systems where standard elastomeric foam is not appropriate.
• Self-Adhesive Closure: Pressure-sensitive acrylate adhesive with non-woven fabric backing for reliable, seamless installation.
• Condensation Control: Built-in vapour barrier prevents condensation on chilled water and refrigerated pipework, reducing the risk of corrosion under insulation (CUI).
• Low Thermal Conductivity: λd ≤ 0.042 W/(m·K) at 40°C (tubes), minimising heat loss and improving energy efficiency.
• Fire Safety: D(L)-s3,d0 (EN 13501-1), Class 1 (BS 476 Part 7), UL 94 V-0. Self-extinguishing, does not drip or spread flames.
• Environmentally Friendly: CFC/HCFC-free, zero ODP, dust-free and fibre-free.

Applications

Designed for thermal insulation of pipes, vessels, and ducts in solar collectors (including outdoors), heat pump systems, motor vehicles, hot gas lines, steam lines, and dual temperature lines. UV resistance and durability make it ideal for external pipework exposed to sunlight.

Installation

For all outdoor installations, Armacell recommends bonding all longitudinal seams and butt joints using HT625 adhesive to minimise natural longitudinal shrinkage and maintain sealed joint integrity. Mechanical fixings alone are not a substitute for adhesive at joints. For sealing exposed joints and repairs, use Armaflex HT Solar Tape. Also available as a pre-slit tube for easier installation on existing pipework.
