Upgraded PU & Phenolic Board Thermal Insulation | Tianjin Jinsimai Supplies Fireproof Energy-Saving Materials for Global Zero Carbon Construction & Public HVAC Projects

Recently, Tianjin Jinsimai Building Materials Technology has fully upgraded the formulas and production processes of two premium insulation lines: rigid polyurethane board/pipe and Class A phenolic board. The optimized thermal insulation products have passed authoritative re-certifications from multiple countries and are shipped in bulk to dozens of nations worldwide. They are widely applied to passive ultra-low-energy buildings, cold chain parks, as well as ventilation and fire protection renovation projects in schools and hospitals overseas.

This product iteration addresses three core pain points frequently raised by global HVAC contractors: overly thick insulation layers, performance degradation under high temperatures, and insufficient fire resistance for ventilation ducts. Jinsimai delivers an integrated thermal insulation solution combining outstanding energy efficiency and fire safety.

1. Industry Background: Updated Global Codes Drive Insulation Material Upgrades

In recent years, the EU, Southeast Asia, the Middle East and other regions have revised building energy efficiency and fire safety regulations. Stricter thermal insulation standards are enforced for nearly zero-energy buildings, while Euroclass A1 fire resistance has become mandatory for ventilation ducts in all public buildings.

Conventional single-type insulation cannot deliver both ultra-low thermal conductivity and high fire performance. Overseas contractors are forced to source materials from multiple suppliers, pushing up overall costs of procurement, installation and inspection. The global construction market is in urgent demand for one-stop high-performance insulation systems.

Drawing on years of practical experience from overseas projects, Jinsimai’s R&D team optimized material formulas tailored to diverse climates and building types. Fully automatic foaming production lines have been renovated to guarantee stable mass production of polyurethane board, polyurethane pipe and phenolic board products.

2. Upgraded Rigid Polyurethane Board & Polyurethane Pipe: Ultra-Thin Thermal Barrier with Long Outdoor Durability

Jinsimai rigid polyurethane insulation covers prefabricated polyurethane board, polyurethane pipe and spray foam variants, featuring an ultra-low thermal conductivity of 0.024 W/(m·K). To achieve equal thermal performance, the required thickness is 20% less than older generations, making it ideal for space-restricted sites such as narrow pipe galleries and retrofits of old building facades; polyurethane pipe is engineered for pipeline thermal preservation scenarios.

Boasting an upgraded closed-cell weather-resistant structure, the polyurethane products deliver a service life of up to 20 years in coastal salt fog, frigid cold and intense tropical heat, drastically cutting long-term maintenance costs. Spray polyurethane forms seamless cladding over irregular equipment to eliminate thermal bridging. Standard polyurethane boards suit prefabricated buildings and pharmaceutical constant-temperature cold storage. All products comply with LEED and BREEAM green building standards and are supplied in bulk to cold chain construction projects across Europe and Southeast Asia.

3. Modified Class A Phenolic Board: Enhanced Toughness for Full-Spectrum Fire Code Compliance

Developed to meet strict fire safety requirements of high-rise public buildings and industrial air ducts, Jinsimai reformulated phenolic resin substrates to resolve common flaws of ordinary phenolic board — brittleness and high breakage rates during transit, cutting cutting and handling damage by 40%.

This phenolic board retains Class A non-combustible performance. It releases no molten drips, minimal smoke and zero toxic fumes when ignited, fully compliant with EU Euroclass A1 and Russian GOST fire codes. Its lightweight design reduces structural load; acid, alkali and aging resistance prevents cracking over long-term use. Installation generates no irritating dust or odor, making it suitable for ventilation pipes in hospitals, shopping malls, machine room inner insulation and clean workshop renovations. It forms a complementary matched insulation system when paired with polyurethane board & polyurethane pipe.

4. Global Bulk Supply & Localized Multilingual Technical Support

Supported by fully automatic intelligent production lines, Jinsimai customizes polyurethane board, polyurethane pipe, phenolic board and special-shaped components in all specifications. All thermal insulation products hold complete international certifications including CE and GOST for global export.

Our multilingual overseas technical team has updated professional insulation selection manuals, providing customized material matching schemes for high-temperature, frigid and coastal high-humidity operating conditions. Global general contractors and HVAC suppliers can streamline procurement and source energy-saving & fireproof insulation materials from a single manufacturer.

5. Corporate Statement & Long-Term Development Plan

A technical lead from Jinsimai stated: “All upgrades to our insulation product lines are developed based on real feedback from hundreds of overseas construction projects. Instead of manufacturing isolated thermal insulation materials, we have built a complete portfolio integrating polyurethane board, polyurethane pipe and phenolic board. It addresses two core market demands: extreme energy efficiency for zero-carbon buildings and mandatory fire safety standards for public facilities. Aligned with the global trend of low-carbon and safer construction, we consistently supply full-lifecycle cost-saving insulation materials for engineering projects worldwide.”

Moving forward, the company will ramp up R&D investment in special thermal insulation materials engineered for extreme weather environments, expand overseas warehouse networks to shorten global order delivery cycles, and further deepen its footprint in the global market for green buildings and industrial energy-saving retrofits.
