Astino New Sunroof 25 PU Metal — Superior Thermal Efficiency & Leak-Proof Design | Bumbung Metal Deck Berinsulasi PU

 

The Astino New Sunroof 25 PU Metal is a premium 3-in-1 insulated roofing system featuring a high-density Polyurethane (PU) core bonded between two protective metal skins. Engineered for maximum heat reflection and structural rigidity, it is the definitive choice for temperature-sensitive industrial and commercial developments across Malaysia.

 

PRODUCT DESCRIPTION

• In Malaysia’s volatile climate, standard metal decking often fails to address two critical issues: extreme solar heat gain and internal condensation. For Project Managers and Main Contractors, these failures lead to skyrocketing cooling costs and structural moisture damage. Traditional roofing requires separate layers of insulation and netting, increasing labor risks and installation time on-site.
• The Astino New Sunroof 25 PU Metal eliminates these complexities by providing a factory-bonded, sandwich-panel solution. The 25mm high-rib profile is engineered with a specialized anti-capillary groove along the side laps, effectively breaking water surface tension to prevent backflow—even during the heaviest monsoon downpours. The CFC-free Rigid Polyurethane foam provides a superior thermal barrier, significantly reducing “indoor radiant heat” and keeping electricity consumption for HVAC systems at a minimum.
• Kee Maju Jaya ensures your project timeline remains uninterrupted through our robust supply chain. We maintain high stock consistency for major industrial specifications, offering reliable site delivery to key hubs including Kuala Lumpur, Selangor, Penang, Johor, and the East Coast.

KEY TECHNICAL FEATURES

• Dual-Layer Metal Skin: Provides 2x the protection against mechanical impact and ensures the PU core is never exposed to the elements, extending the roof’s lifespan significantly.
• High-Density Rigid PU Foam: Exceptional thermal resistance ($R-Value$) that blocks solar radiation, maintaining internal building temperatures up to 5°C–8°C cooler than standard metal decks.
• Integrated Anti-Capillary Groove: A precision-engineered rib feature that prevents water seepage via capillary action, ensuring a 100% leak-proof side lap.
• CFC-Free Polyurethane: Environmentally responsible insulation that offers excellent sound absorption, reducing “rain noise” levels common in Malaysian warehouses.

 

APPLICATIONS & BENEFITS

• Industrial (Factories & Warehouses): Provides heavy-duty protection and fire-smoke resistance. Benefit: Reduces operational energy costs and meets stringent industrial safety requirements.
• Commercial (Showrooms & Malls): Offers a sleek, modern aesthetic with various color coatings. Benefit: Combines premium branding visuals with high-performance thermal comfort for visitors.
• Coastal Regions (East Coast/Penang): High-grade protective coatings (Aluzinc/Galvanized). Benefit: Superior corrosion resistance (Tahan Karat) against salt-mist and high humidity environments.
• Agricultural (Poultry & Greenhouses): Consistent temperature regulation. Benefit: Optimizes livestock productivity and crop yield by preventing heat stress.

FAQ SECTION

Question 1: Why is Astino New Sunroof 25 PU Metal preferred over standard PU Foam roofing?

Answer 1: Unlike standard PU Foam (which uses PVC or Foil backing), the PU Metal variant features metal skins on both sides. This provides superior structural integrity, better fire resistance, and protects the insulation from pests and mechanical damage, making it the most durable choice for Malaysian industrial sites.

Question 2: How does the anti-capillary groove in the Sunroof profile prevent leaks?

Answer 2: During heavy tropical storms, water can be “sucked” into the laps of metal sheets via capillary action. The Astino New Sunroof profile includes a dedicated groove that breaks this tension, ensuring water is discharged safely down the ribs rather than into your building.

Question 3: What is the recommended roofing solution for high-heat warehouses in Selangor?

Answer 3: We recommend the Astino New Sunroof 25 PU Metal. Its 25mm PU core acts as a high-performance thermal bridge, significantly reducing heat transfer from the roof surface to the interior, which is essential for warehouses without active air conditioning.

Question 4: Can I get customized lengths for large-scale projects in Johor?

Answer 4: Yes. Kee Maju Jaya provides custom-cut lengths to minimize end-laps and reduce wastage on-site. We offer direct factory value and coordinated logistics for site delivery across Johor and the Southern region.

 

Soalan 1: Mengapakah Astino New Sunroof 25 PU Metal lebih baik berbanding bumbung PU Foam biasa?

Jawapan 1: Berbeza dengan PU Foam biasa (yang menggunakan lapisan belakang PVC atau kerajang), varian PU Metal mempunyai lapisan logam di kedua-dua belah pihak. Ini memberikan integriti struktur yang lebih kukuh, rintangan api yang lebih baik, serta melindungi penebat daripada perosak dan kerosakan mekanikal, menjadikannya pilihan paling tahan lama untuk tapak industri di Malaysia.

Soalan 2: Bagaimanakah alur anti-kapilari (anti-capillary groove) pada profil Sunroof menghalang kebocoran?

Jawapan 2: Ketika ribut tropika yang lebat, air boleh “disedut” ke dalam pertindihan kepingan logam melalui tindakan kapilari. Profil Astino New Sunroof dilengkapi dengan alur khas yang memutuskan tegangan ini, memastikan air mengalir keluar dengan selamat melalui tulang bumbung dan bukannya masuk ke dalam bangunan anda.

Soalan 3: Apakah penyelesaian bumbung yang disyorkan untuk gudang yang bersuhu tinggi di Selangor?

Jawapan 3: Kami mengesyorkan Astino New Sunroof 25 PU Metal. Teras PU 25mm berfungsi sebagai jambatan terma berprestasi tinggi yang mengurangkan pemindahan haba dari permukaan bumbung ke dalam bangunan secara drastik—aspek kritikal untuk gudang tanpa sistem penyaman udara aktif.

Soalan 4: Bolehkah saya mendapatkan panjang bumbung mengikut saiz tempahan untuk projek besar di Johor?

Jawapan : Ya. Kee Maju Jaya menyediakan pemotongan panjang mengikut spesifikasi (custom-cut) bagi meminimumkan pertindihan hujung dan mengurangkan pembaziran di tapak projek. Kami menawarkan nilai harga kilang terus dan logistik yang teratur untuk penghantaran ke tapak di sekitar Johor dan wilayah Selatan.
