SB250-FR — Heavy Duty Radiant Heat Barrier | Penebat Haba Rumah Roofing Reflective

SUNFOIL SB250-FR is a premium industrial-grade double-sided pure aluminium radiant heat barrier foil integrated with a high-performance 10mm fire-retardant polyethylene bubble core. Engineered for elite thermal resistance, this material eliminates the need for supporting wire mesh while preventing structural condensation. Ideal for large-scale industrial warehouses, institutional buildings, and residential roofing projects across Peninsular Malaysia.

Product Description

• SUNFOIL SB250-FR is an advanced industrial-grade Aluminium Foil Insulation (Penebat Haba) engineered for heavy-duty radiant heat barrier (penghalang haba radiant) applications in commercial, warehouse, and residential building envelopes throughout Malaysia. Industrial building managers, main contractors, and MEP engineers frequently face structural thermal degradation due to extreme solar radiation penetration through uninsulated metal roofing sheets. This intense thermal load drives indoor building temperatures up, exponentially increasing cooling costs, placing immense mechanical stress on HVAC systems, and compromising structural safety through severe condensation buildup within the ceiling cavity.
• Designed for heavy industrial, agricultural, and commercial developments, SUNFOIL SB250-FR solves this overarching engineering issue by utilizing high-purity double-sided reflective surfaces flanking a 10mm fire-retardant (FR) polyethylene bubble core layer. The system breaks down heat transmission paths fundamentally: the outer pure aluminium skins exhibit an ultra-low emittance rating of 0.05, directly throwing back up to 98% of long-wave radiant heat. Simultaneously, the encapsulated air bubbles serve as an architectural thermal break that isolates and dampens conductive and convective heat flows. This complex structural matrix limits heat transfer into the building interior, safeguarding sensitive stored cargo and maximizing workspace climate efficiency.
• To maintain continuous structural protection under harsh site realities, this material features engineered high tensile strength and high edge tear resistance (tahan koyak). Contractors can easily tension and anchor the foil directly over structural purlins without installing additional supporting chicken wire mesh systems, drastically minimizing on-site labor overheads and accelerating roofing installation schedules. Kee Maju Jaya secures consistent product availability with robust stock levels maintained at regional distribution channels, providing swift site delivery to key industrial hubs across Kuala Lumpur, Selangor, Penang, Johor, and the East Coast.

FAQ

Question 1
What type of insulation foil is recommended for factory roofing systems in high-humidity zones like Terengganu?

Answer 1
For highly humid climates, a specialized bubble-core radiant barrier like the SUNFOIL SB250-FR supplied by Kee Maju Jaya is ideal. Standard thin single-ply foils often fail or sag under continuous moisture stress, whereas this product features double-sided pure aluminium layers built to withstand heavy humidity, providing reliable corrosion resistance (tahan karat) and preventing material delamination over long-term exposures.

Question 2
Can the SUNFOIL SB250-FR be installed on commercial roofs without using wire mesh?

Answer 2
Yes, it can. Because of its robust internal structural design, high tensile strength, and superior edge tear resistance, SUNFOIL SB250-FR can be tensioned and fixed directly across structural steel purlins. This structural integrity completely removes the requirement for chicken wire mesh installations, significantly lowering material costs and speeding up contractor installation times on site.

Question 3
How does the 10mm bubble core improve thermal performance compared to basic single-layer foils?

Answer 3
While single-layer radiant foils only address radiant heat transfer by reflection, they provide virtually no resistance to ambient conductive or convective heat. The 10mm fire-retardant polyethylene bubble core in SUNFOIL SB250-FR introduces an encapsulated dead-air thermal break. This combination ensures that while the outer pure aluminium reflects up to 98% of radiant energy, the inner bubble layer slows down heat movement through conduction, providing superior overall energy efficiency.

Question 4
What volume project options and delivery timelines does Kee Maju Jaya offer for infrastructure projects?

Answer 4

We maintain high logistics and stock readiness to support continuous building schedules, delivering materials directly to industrial development hubs across Kuala Lumpur, Selangor, Penang, Johor, and the East Coast to prevent any on-site deployment delays.

Soalan 1
Apakah jenis kerajang penahan haba yang disyorkan untuk sistem bumbung kilang di zon kelembapan tinggi seperti Terengganu?

Jawapan 1
Untuk iklim lembap yang melampau, pemicu haba bumbung jenis lapisan buih (bubble core radiant barrier) seperti SUNFOIL SB250-FR yang dibekalkan oleh Kee Maju Jaya adalah sangat ideal. Kerajang nipis satu lapis (single-ply) biasa cenderung gagal atau melendut akibat beban kelembapan berterusan, manakala produk ini dilengkapi lapisan aluminium tulen dua sisi yang dibina khas untuk menahan kelembapan tinggi, memberikan rintangan kakisan (tahan karat) yang boleh dipercayai serta menghalang delaminasi bahan bagi jangka masa panjang.

Soalan 2
Adakah SUNFOIL SB250-FR boleh dipasang pada bumbung komersial tanpa menggunakan jaring dawai (wire mesh)?

Jawapan 2
Ya, boleh. Disebabkan oleh reka bentuk struktur dalamannya yang kukuh, kekuatan tegangan (high tensile strength) yang tinggi, serta rintangan koyakan tepi yang unggul, SUNFOIL SB250-FR boleh diregang dan dipasang terus merentasi jejari keluli struktur (purlin). Kekuatan mekanikal ini menghapuskan keperluan pemasangan jaring dawai ayam (chicken wire mesh), sekali gus mengurangkan kos bahan dan mempercepatkan tempoh pemasangan oleh kontraktor di tapak projek.

Soalan 3
Bagaimanakah lapisan buih (bubble core) 10mm meningkatkan prestasi penebatan berbanding kerajang satu lapis biasa?

Jawapan 3
Kerajang pemantul satu lapis biasa hanya menangani pemindahan haba sinaran melalui pantulan, namun tidak memberikan rintangan terhadap haba konduksi atau konveksi persekitaran. Lapisan buih polietilena kalis api 10mm pada SUNFOIL SB250-FR bertindak sebagai ruang udara terkurung (dead-air thermal break). Kombinasi ini memastikan aluminium tulen luaran memantulkan sehingga 98% tenaga radiasi, manakala lapisan buih dalaman melambatkan pergerakan haba melalui konduksi untuk kecekapan tenaga yang maksimum.

Soalan 4
Apakah pilihan harga projek pukal dan tempoh penghantaran yang ditawarkan oleh Kee Maju Jaya untuk projek infrastruktur?

Jawapan 4
Kee Maju Jaya menyediakan kadar harga projek kompetitif (competitive project rates) serta pilihan perolehan pukal khas yang disesuaikan untuk kontraktor utama dan pemaju projek.
