Direct-from-factory high-performance insulated roof panels manufactured on continuous European-standard laminating lines. Fully compliant with ASTM, AS/NZS, and Thai TISI building envelope codes.
Thailand’s equatorial tropical wet-and-dry climate (Köppen Aw) subjects industrial and commercial roof envelopes to severe microclimatic pressures. With annual global solar irradiation averaging between 1,800 and 2,000 kWh/m² and summer roof-skin surface temperatures frequently surpassing 78°C in non-insulated metal decks, radiant thermal flux into manufacturing shop floors creates an intolerable heating load on HVAC systems.
Standard single-skin metal cladding overlaid with field-laid glass wool insulation blanket routinely fails in Southeast Asia due to interstitial condensation. When humid outdoor air (relative humidity hovering between 75% and 92%) migrates into poorly sealed cavities, it strikes the cooled internal foil membrane, creating localized vapor saturation, insulation compression, mold infestation, and catastrophic under-roof corrosion.
Moreover, during the torrential monsoon season from May to October, rainfall intensity across central and eastern Thailand can reach instantaneous peaks of 120 mm/hour. Our engineered trapezoidal roof profiles feature 38 mm to 42 mm high standing ribs, integrated capillary micro-grooves, and concealed screw cap overlap joints that prevent hydraulic head pressure leakage during horizontal wind-driven deluges.
Optimizing structural payload, thermal U-values, non-combustibility criteria, and cost efficiency across industrial, cold storage, and chemical infrastructure projects in Thailand.

Engineered specifications tuned to the regulatory, thermal, and atmospheric demands of Thailand's specialized industrial provinces and special economic zones.
Advanced automotive, electric vehicle (EV), and high-tech electronic mega-factories in Amata City and WHA Mega Industrial Estates. Our PIR roof panels with 55% Al-Zn Galvalume steel skins (AZ150) deliver zero-maintenance resistance against coastal salt fog and aggressive acidic industrial particulates.
Mega-chillers, frozen seafood export hubs, and tropical fruit logistics centers requiring continuous interior thermal stabilization (-25°C to +4°C). Injected high-density PUR/PIR tongue-and-groove joint panels prevent vapor migration, icing buildup, and thermal bridging at joint overlaps.
Refineries, plastics synthesizers, and chemical warehouses requiring absolute adherence to Thailand Ministerial Fire Regulations. Our Class A1 continuous basalt rock wool sandwich roof systems provide 120 to 240 minutes of structural fire containment without emitting toxic fumes or flammables.
Seafood processing facilities in Surat Thani and Songkhla exposed to continuous internal washing, organic brine moisture, and high marine humidity. We configure heavy-gauge PVDF or food-safe anti-microbial coatings resistant to caustic sanitation detergents and severe saltwater corrosion.
Strategic shifts in green building standards, regulatory mandates, and clean energy synergy driving architectural adoption across Southeast Asia.
The Department of Alternative Energy Development and Efficiency (DEDE) has mandated strict Overall Thermal Transfer Value (OTTV) thresholds below 30–50 W/m² for newly constructed buildings exceeding 2,000 m². Conventional double-skin sheeted roofs with sagging fiberglass fail these rigorous heat flux audits. Pre-engineered continuous PIR composite roof panels are now the specified default envelope system for EPC contractors bidding on institutional, aviation, and Grade-A logistics warehouses across Thailand.
Driven by high commercial electricity tariffs (approaching 4.5–5.0 THB/kWh) and national Net Metering initiatives, over 80% of new factory builds in Chonburi and Rayong integrate massive rooftop solar arrays. This demands roof panels engineered with superior compressive core strength (>160 kPa) and reinforced high-rib profiles capable of supporting ballast-free solar mounting clamps without puncturing the waterproof membrane or crushing the insulating matrix.
Multinational manufacturers expanding in Thailand under BOI (Board of Investment) privileges are targeting international green building credits (LEED v4 or Thailand's Rating of Energy and Environmental Sustainability - TREES). Our continuous production process utilizes zero-ODP, low-GWP pentane blowing technology, entirely free of CFCs and HCFCs, providing significant Life Cycle Assessment (LCA) points and carbon footprint offsets for corporate sustainability reports.
