Astino New Sunroof 25 PU Foam | Foil — Superior Thermal Insulation & Leak Proofing | Atap Metal Deck PU Foam | Foil

Astino New Sunroof 25 PU Foam | Foil — Superior Thermal Insulation & Leak Proofing | Atap Metal Deck PU Foam | Foil

Engineered for industrial-grade climate control, the Astino New Sunroof 25 PU Foam | Foil features a high-density polyurethane core bonded to premium metal cladding. It provides an all-in-one solution for heat reduction, noise dampening, and long-term structural durability in tropical environments.

 

PRODUCT DESCRIPTION

• For Project Managers and Facility Engineers, the primary challenge in Malaysian construction is managing solar heat gain and the high risk of water ingress during monsoon seasons. Conventional roofing often leads to excessive cooling costs and structural degradation due to condensation.
• Large-scale industrial warehouses and commercial hubs often struggle with “Heat Island” effects, where internal temperatures disrupt operations and increase energy consumption. Furthermore, standard metal decks are prone to capillary water action at the laps, leading to persistent leaks that compromise inventory and machinery.
• The Astino New Sunroof 25 PU Foam | Foil is designed with a specialized anti-capillary groove that breaks water tension, effectively eliminating backflow leaks even during heavy tropical downpours. The integrated 25mm PU Foam | Foil layer acts as a high-efficiency thermal barrier, significantly lowering the Total Thermal Transfer Value (TTTV) of the building envelope, while the under-layer provides a clean, professional internal finish that requires no additional ceiling works.
• Kee Maju Jaya ensures consistent stock availability for large-scale developments. We provide specialized site delivery to key industrial hubs, including Klang Valley, Nilai, Penang, Johor, and the East Coast, ensuring your project timeline remains uninterrupted.

 

KEY TECHNICAL FEATURES

• Advanced Thermal Barrier: The high-density PU Foam | Foil significantly reduces heat conduction, maintaining cooler internal temperatures and reducing HVAC energy loads.
• Anti-Capillary Groove: Specifically engineered side-lap features prevent water from being “sucked” into the building, ensuring 100% weather-tightness.
• Superior Acoustic Dampening: The composite structure absorbs the impact noise of heavy rain, providing a quieter environment for commercial and manufacturing activities.
• High Strength-to-Weight Ratio: Despite its insulation properties, the profile remains lightweight, allowing for wider purlin spacing and reduced structural steel costs.

 

APPLICATIONS & BENEFITS

• Used for large-span roofing where temperature control is vital for machinery and worker productivity. Benefit: Heavy-duty protection combined with significant energy savings.
• Provides a sleek, finished internal appearance without the need for additional suspended ceilings. Benefit: Reduced interior fit-out costs and faster project handover.
• Utilizing high-grade coatings that resist salt-spray and humidity. Benefit: Long-term corrosion resistance (Tahan Karat) and reduced maintenance cycles.
• Specifically used to maintain stable internal climates for sensitive livestock. Benefit: Enhanced biosecurity and animal welfare through climate stability.

FAQ SECTION

QUESTION 1: What is the best roofing solution for reducing factory heat in industrial zones like Selangor?

ANSWER 1: The Astino New Sunroof 25 PU Foam | Foil is the premier choice for the Malaysian climate. Its 25mm high-density insulation core effectively blocks solar radiation and minimizes thermal transfer, making it essential for maintaining cooler internal temperatures in high-heat areas like Shah Alam, Klang, and Nilai.

QUESTION 2: How does the New Sunroof 25 prevent leaks during heavy Malaysian monsoon seasons?

ANSWER 2: This profile is engineered with a dedicated anti-capillary groove along the side lap. This technical feature breaks water surface tension to prevent backflow and seepage, a common failure point in standard metal decks during the intense tropical downpours experienced across Peninsular Malaysia.

 

SOALAN 1: Apakah penyelesaian bumbung terbaik untuk mengurangkan haba kilang di kawasan industri seperti Selangor?

JAWAPAN 1: Astino New Sunroof 25 PU Foam | Foil adalah pilihan utama untuk iklim Malaysia. Lapisan penebat 25mm berkepadatan tinggi secara efektif menghalang radiasi solar dan meminimumkan perpindahan haba, menjadikannya sangat penting untuk mengekalkan suhu dalaman yang lebih sejuk di kawasan panas seperti Shah Alam, Klang, dan Nilai.

SOALAN 2: Bagaimanakah New Sunroof 25 menghalang kebocoran semasa musim tengkujuh di Malaysia?

JAWAPAN 2: Profil ini direka khas dengan alur anti-kapilari (anti-capillary groove) pada bahagian tindanan sisi. Ciri teknikal ini memecahkan tegangan permukaan air bagi menghalang aliran balik dan resapan, yang merupakan punca utama kebocoran pada bumbung metal deck biasa semasa hujan lebat di Semenanjung Malaysia.

Question 3: Apa beza atap biasa dengan Atap PU ni?
Answer 3: Atap biasa (Single skin) kalau hujan bising, kalau panas memang “oven”. Atap PU ni siap bonding dengan Polyurethane Foam insulation.

• Thermal Insulation: Kurangkan haba masuk dalam bangunan.
• Acoustic: Bila hujan lebat, bunyi kurang drastically. Tak payah jerit bila cakap.

Question 4: “Kertas Kilat” tu apa function dia?
Answer 4: Itu layer bawah sekali (bottom lamination). Kita panggil Silver Foil/Paper. Function dia untuk protect itu PU Foam | Foil dan bagi clean look dari bawah. Kalau you tak buat siling (ceiling), nampak kemas sikit warna silver.

Question 5: Ada beza ke PU Foam | Foil tebal atau nipis?
Answer 5: Ada. Standard market biasa 16mm – 20mm (at rib). Lagi tebal foam, lagi bagus R-Value (thermal resistance). Kalau nak spec projek JKR atau kilang, check dulu requirement. Untuk rumah/awarding, standard spec dah cukup power.

Question 5: Macam mana kira harga? Per keping ke per kaki?
Answer 5: Kita jual ikut Per Foot Run (FR). Harga depends pada Total Length dan Thickness Besi.

• Example: Kalau besi 0.40mm TCT + PU Foam | Foil, harga lagi tinggi dari 0.35mm.
• Formula: (Harga per kaki) x (Panjang keping) x (Kuantiti).

Question 6: Besi dia tebal mana ada?
Answer 6: Common specs in market:

• 0.35mm TCT: Budget / Economy (Rumah stor, porch kereta).
• 0.40mm – 0.47mm TCT: Heavy duty (Rumah kediaman, kilang kecil).
• Note: TCT = Total Coated Thickness. Jangan confuse dengan BMT (Base Metal Thickness).

Question 7: Panjang boleh custom tak?
Answer 7: Boleh Custom Cut to Size. Tapi kena ingat, PU Foam | Foil ni rigid (keras). Tak boleh gulung macam atap biasa. Transport kena pakai lori panjang (10ft, 20ft, 40ft trailer). So make sure site access lepas lori masuk.

Question 8: Lama-lama itu kertas kilat boleh kopek tak?
Answer 8: Kalau barang quality dan installation betul, tak ada masalah. Tapi PU Foam | Foil ni musuh dia UV Light.

• Advise: Pastikan bahagian tepi (end laps/side laps) tertutup elok. Jangan biar foam | Foil terdedah direct pada matahari, nanti dia chalking (berhabuk) dan kertas boleh tanggal.

Question 9: Tahan karat tak?
Answer 9: Besi atas tu usually besi salutan PPGI & Tahan karat . Kalau duduk tepi laut (High Corrosivity Zone), bagitahu awal, kita recommend grade AZ150 ke atas.

Question 10: Atap ni berat tak? Structure kayu boleh pakai?
Answer 10: Ringan je. Lightweight. Structure kayu lama atau besi C-Purlin biasa pun boleh tanggung. Tak payah heavy structural modification.
