Brief Description:Foil-faced rock wool pipe sections are A1 non-combustible insulation materials with superior vapour barrier and heat reflection performance. Featuring corrosion and weather resistance, they suit high-temperature, outdoor and corrosive pipework. Custom self-adhesive foil enables fast, convenient installation.

Foil-faced rock wool pipe sections are upgraded pipe insulation products manufactured by Haochen Insulation. Using A1 non-combustible basalt rock wool pipe sections as the base material, they are bonded with a heavy-duty aluminium foil protective layer under high temperature. Combining the fire and thermal performance of rock wool with the vapour barrier, radiant heat reflection, corrosion resistance and weathering resistance of aluminium foil, this product is designed specifically for pipe insulation under high-temperature, exposed outdoor, high-humidity and corrosive operating conditions.

The base material features dense fibres and low thermal conductivity, delivering consistent thermal insulation, sound absorption and fire retardancy. It effectively reduces heat and cold loss of pipework and eliminates condensation and dripping. The aluminium foil facing provides excellent sealing, reflecting radiant heat and blocking vapour ingress. It fundamentally resolves common defects of standard rock wool pipe sections such as fibre degradation from moisture, insulation failure and ageing detachment, greatly extending the service life and stability of the pipe insulation system.

We offer customisation for plain aluminium foil facing and self-adhesive overlapping aluminium foil facing. The self-adhesive variant is quick to install with tight joints and requires no additional waterproof covering, bringing high construction efficiency and neat finishing. The complete assembly is A1 non-combustible, resistant to high temperatures and releases no harmful smoke, fully complying with fire acceptance standards for building and industrial projects.

This product is anti-ageing, rain-resistant, corrosion-proof and tolerant of temperature fluctuations. It suits harsh environments including exposed outdoor pipework, high-temperature steam pipelines, ventilation ducts, humid service shafts, pump rooms and corrosive chemical plants. Widely used in industrial heating, HVAC systems, building pipe networks and renovation projects for new and existing pipelines, it acts as the preferred upgraded insulation material for pipe systems requiring high-grade protection.

Core Product Features

• Dual thermal insulation: heat retention from rock wool core plus radiant heat reflection by aluminium foil for superior energy-saving performance

• Fully sealed vapour barrier and moisture resistance: prevents vapour penetration and avoids insulation failure caused by dampness

• A1 fire classification and high-temperature resistance: non-combustible and flame-retardant, suitable for high-temperature pipe service

• Weathering, corrosion and ageing resistance: applicable to complex outdoor, damp and corrosive environments

• Simple and neat installation: self-adhesive overlapping option available for tight sealing and labour-saving fitting

Application Scope

High-temperature steam pipelines, hot and cold HVAC pipework, ventilation ducts, exposed outdoor pipe networks, underground humid service shafts, pump rooms, industrial high-humidity corrosive plants, and upgrade & renovation works for aged pipe insulation.
