K-Flex K-Rock Foiled Mineral Wool Pipe Insulation - 1mのレビュー

K-Flex K-Rock Foiled Mineral Wool Pipe Insulation – 1m K-Flex K-Rock Foiled is a pre-formed mineral wool pipe section with an aluminium foil (ALU) vapour barrier facing, certified to EN 14303:2009+A1:2013. With a Euroclass A1 non-combustible fire rating and a service temperature range of -50°C to +600°C, it is the specified choice for high-temperature heating, steam, industrial process pipework, and HVAC applications where elastomeric foam is not suitable. Supplied in pre-slit 1m sections for 15mm to 114mm pipe outside diameter, with 20mm and 25mm wall thicknesses. Key Features & Benefits Euroclass A1 Non-Combustible: Highest fire classification under EN 13501-1 — will not contribute to fire spread, smoke, or burning droplets. Essential for commercial, industrial, and public sector projects. High Temperature Rated: Continuous service from -50°C to +600°C — suitable for steam, boiler, and high-temperature process pipework. Low Thermal Conductivity: λ(0°C) ≤ 0.034 W/(m·K); λ(50°C) ≤ 0.038 W/(m·K) — excellent thermal performance across the full service range. Acoustic Performance: Mineral wool construction reduces noise from fluid flow and mechanical vibration in commercial pipe runs. ALU Foil Facing: Aluminium foil vapour barrier (WS01 water permeability rating) with self-adhesive overlap for a clean, professional finish. Low Chloride Content: ≤10 ppm water-soluble chloride ions (CL10) — minimises corrosion risk on stainless steel and copper pipework. Part L & BS 5422 Compliant: Suitable for meeting pipe insulation requirements under Part L of the Building Regulations. Technical Specifications Material: Mineral wool with aluminium foil (ALU) facing. Length: 1 metre (pre-slit). Wall Thickness Options: 20mm, 25mm. Pipe Size Compatibility: 15mm to 114mm outside diameter. Service Temperature: -50°C to +600°C. Thermal Conductivity: λ(0°C) ≤ 0.034 W/(m·K); λ(50°C) ≤ 0.038 W/(m·K). Fire Classification: Euroclass A1L (EN 13501-1) — non-combustible. Water Permeability: WS01. Chloride Content: ≤10 ppm (CL10). Standard: EN 14303:2009+A1:2013. Installation Open the longitudinal pre-slit, fit around the pipe, and secure the ALU foil overlap with self-adhesive aluminium foil tape or aluminium bands (required above 40°C or for inaccessible installations). For elbows and T-fittings, use segment cuts sealed with foil tape. Process at +10°C to +35°C. Not suitable for outdoor use without additional weatherproof cladding. Applications Domestic heating and hot water pipework (BS 5422 compliant). Industrial process pipework — boilers, ovens, steam lines. HVAC and building services pipework. Acoustic insulation of commercial pipe runs. Fire-rated pipework in commercial and public sector buildings. Complete Your Installation Seal butt joints and the ALU foil overlap with 50mm Self-Adhesive Aluminium Foil Tape for a continuous, professional vapour barrier. For a matching finish at pipe fixings, pair with Rockwool Rocklap Foil-Faced Pipe Supports — the standard mineral wool pipe support for commercial and industrial installations.
