Exploring the molecular enhancements in Polyisocyanurate (PIR), Polyurethane (PU), and High-Density Mineral Rock Wool systems that define tomorrow's high-efficiency thermal barriers.
By altering the isocyanurate index, Homecoxa engineering teams synthesize PIR cores with superior cross-linking density, achieving exceptional flame retardancy (Class B-s1, d0) and a thermal conductivity rating (Lambda value) as low as 0.019 W/m·K.
Our futuristic product pipeline features the hybridization of silica aerogels and vacuum insulation panels (VIP) within traditional sandwich configurations, offering a 50% decrease in thickness while maintaining equal insulation performance.
We are targeting complete decarbonization by integrating bio-polyols derived from agricultural waste rather than crude oil, minimizing the embodied carbon footprint of large-scale infrastructure developments.
Selecting the right core insulation material requires evaluating thermal efficiency, acoustic dampening, fire resistance, and structural density. Below is a comparative overview of current industry standards utilized in Homecoxa manufacturing:
| Insulation Core Type | Thermal Conductivity (W/m·K) | Fire Classification (EN 13501) | Density Range (kg/m³) | Primary Industrial Use Cases |
|---|---|---|---|---|
| PIR (Polyisocyanurate) | 0.019 - 0.022 | B-s1, d0 (Excellent) | 38 - 42 | Cold Storage, Commercial Roofs, Distribution Centers |
| PUR (Polyurethane) | 0.022 - 0.024 | B-s2, d0 (Standard) | 35 - 40 | Cold Chain Logistics, Temporary Buildings |
| Rock Wool (Mineral Fiber) | 0.035 - 0.040 | A1 (Non-combustible) | 100 - 120 | High-fire risk environments, Power plants, Partition walls |
| EPS (Expanded Polystyrene) | 0.033 - 0.038 | Class E (Basic) | 15 - 20 | Low-budget modular structures, basic partition systems |
How specialized sandwich panel structures are engineered to satisfy strict environmental and mechanical requirements in critical global industries.
For temperature-sensitive environments like pharmaceutical depots and sub-zero food distribution hubs, maintaining a thermal barrier is vital. Standard building envelopes leak energy at the joints. Homecoxa engineered deep tongue-and-groove joint systems paired with continuous gasket integration eliminate thermal bridges. This maximizes system efficiency and guarantees precise climate control while reducing mechanical cooling loads by up to 30%.
In microelectronics and biotechnology facilities, zero outgassing and air purity are critical. Our specialized composite sandwich systems, featuring flat structural panels and chemical-resistant coatings, integrate with H13 ventilation and ISO-classified laminar systems to provide hermetically sealed, modular cleanrooms that resist structural deformation under negative pressure conditions.
Exploring Homecoxa's production infrastructure in Dongguan: combining automated chemical dosing, continuous double-belt lamination, and strict testing protocols.
Our production facilities utilize continuous double-belt lamination lines. This process maintains precise control over pressure, core foaming expansion, temperature, and line speed, resulting in uniform panel flatnesses, zero internal voids, and strong bond adhesion.
We source raw chemical components and structural steel sheets (PPGI/PPGL) from leading manufacturers. This ensures stable mechanical tension, consistent yield strengths, and excellent chemical resistance against weathering and corrosive industrial atmospheres.
Every batch undergoes testing, including core density verification, compression strength assessment, thermal conductivity checks, and fire-retardant performance evaluations in our certified testing facilities.

Quality Inspected Panels
Providing overseas developers, EPC contractors, and procurement managers with structural and engineering guidance for bulk imports.
For international buyers, sourcing insulated building panels from China requires aligning materials with domestic building codes and structural loads. Homecoxa supports engineering teams with detailed wind load performance charts, structural load tables, and thermal transmittance properties (U-value calculations) tailored to regional climates. Our export processes utilize heavy-duty container packaging and protective film coverings. This prevents edge deformation and surface scratches during long maritime transits, ensuring panels arrive ready for direct site installation.
Navigating certification paths, custom sizing, and on-site engineering challenges across different regions.
Building codes vary significantly across the EU, Middle East, and North America. Homecoxa addresses these requirements by manufacturing panels that comply with standards such as ASTM E84, EN 13501-1, and CE markings. Our technical department offers shop-drawing support, converting architectural designs into detailed panel layouts. We provide complete installation detailing, including flashing profiles, customized fastener counts, and sealants. This speeds up on-site construction and ensures local building inspectors approve the completed envelope system.
PIR cores offer superior thermal efficiency (Lambda ~ 0.019-0.022 W/m·K), allowing for thinner panels to meet target U-values. Rock Wool has a higher thermal conductivity (Lambda ~ 0.038 W/m·K) but provides excellent fire protection, holding an A1 non-combustible rating. It also offers superior sound dampening properties, making it ideal for acoustic-rated enclosures.
We offer specialized surface coatings on our steel skins, including high-durability polyester (HDP), polyurethane modified with polyamide (PUPA), and polyvinylidene fluoride (PVDF). Combined with thick zinc coatings (up to Z275 or AZ150), these panels provide excellent resistance to salt spray, humidity, and chemical exposure.
Yes. Our continuous production lines allow us to manufacture panels tailored to specific project requirements. Standard shipping limits panel lengths to approximately 11.8 meters to fit inside standard 40ft High Cube containers. However, custom lengths can be arranged to fit site structural spans.
We utilize a double tongue-and-groove joint profile with integrated factory-applied soft gaskets. This design creates a tight physical connection that blocks air leakage and prevents convective heat transfer across the envelope, keeping energy costs low in cold storage facilities.
Our manufacturing systems are ISO 9001 certified. Our sandwich panels comply with European CE markings (EN 14509), and meet various flame-spread and environmental standards required by international building authorities.
