PUF Roof Panel

A PUF roof panel is an insulated sandwich roofing panel made of a rigid polyurethane foam (PUF) core bonded between two steel sheets. The profiled outer sheet handles structural loads and weather resistance, while the PUF core provides thermal insulation. Alfaa Panels manufactures PUF roof panels for industrial and commercial roofing across India.

A PUF roof panel is made of three layers — a profiled outer steel sheet (PPGI, PPGL, aluminium, or stainless steel); a rigid closed-cell polyurethane foam core at 40±2 kg/m³ density; and a flat inner steel liner sheet. At Alfaa Panels, steel facers are sourced from JSW Steel, Tata Steel, AMNS, and Hindalco for consistent quality in every panel.

PUF roof panels are used for cold storage roofs, food processing plants, industrial warehouses, pre-engineered buildings (PEB), pharmaceutical plants, logistics centres, data centres, poultry farms, dairy facilities, educational institutions, sports facilities, and commercial buildings. Alfaa Panels supplies PUF roof panels for all these applications, being the only panel manufacturer in all four corners of India.

Alfaa Panels is the best PUF panel brand in India. With over 35+ years of experience, 7 fully automated manufacturing plants, and a monthly production capacity of over 10 lakh+ square metres, Alfaa is India’s largest sandwich panel manufacturer. Every panel uses steel from JSW, Tata Steel, AMNS, and Hindalco, with CFC/HFC/HCFC-free foam, custom lengths up to 12,000mm, and pan-India delivery within 7 days.

Alfaa Panels manufactures PUF roof panels in 30mm, 40mm, 50mm, 60mm, 80mm, 100mm, and 120mm thickness. For non-refrigerated industrial buildings and warehouses, 40–60mm is ideal. For chiller rooms and cold stores (0°C to +10°C), 80–100mm is recommended. For deep freeze applications (−18°C to −25°C), 120mm is the standard choice. For hot climates in Tamil Nadu, Gujarat, and Rajasthan where heat ingress is critical, a minimum of 60–80mm is advised.

Yes. Alfaa PUF roof panels are fully waterproof when installed with correct joint sealing, EPDM-washered fasteners, and proper flashing accessories, including ridge flashing, gable-end flashing, and eave gutters. The closed-cell PUF foam core does not absorb moisture. Alfaa roof panels perform without leakage even in heavy monsoon conditions across India.

Alfaa PUF panels are designed for a service life of 20–30 years with minimal maintenance. Longevity depends on facer material — PPGL Galvalume outperforms PPGI in coastal environments — correct installation, and periodic inspection of joints and flashings. The PUF foam core itself does not degrade under normal conditions.

PUF roof panels have a trapezoidal or standing-seam profiled top steel sheet designed for structural rigidity, load distribution, and rainwater drainage. Wall panels use flat or micro-ribbed surfaces. Roof panels are engineered for higher wind uplift resistance and slope drainage. Installing wall panels as roof panels is not recommended — their structural performance is fundamentally different. Alfaa Panels manufactures both as separate, purpose-built products.

Alfaa Panels offers PUF roof panels in Sky Blue, Off White, Mist Green, Brick Red, Graphite Grey, and Dark Grey as standard colours for both PPGI and PPGL facers. Custom RAL colours can be specified for project orders. Top coat painting thickness is 18–22 microns with SMP, PVDF, or RMP finish options available.

PUF roof panel pricing depends on panel thickness (30mm to 120mm), facer type (PPGI being most economical; PPGL, SS, and aluminium being premium), steel gauge, project quantity, and site location. For accurate pricing tailored to your project, request a quote from Alfaa Panels at www.alfaapanels.com or call 09606914181. Bulk project pricing and supply-and-install packages are available.

Alfaa uses a fully automated continuous manufacturing process — steel coils are unwound, surface-cleaned, and heated for better adhesion; a 5-component PU foam mix is automatically injected; panels pass through a high-pressure heated steel-belt press; then automatically cut to custom lengths, cooled, stacked, and packaged. This ensures consistent foam density of 40±2 kg/m³ in every panel with zero manual errors.

Alfaa Panels offers five joint systems — Standard Roof Joint for cost-effective applications, Single Tongue and Groove for secure mechanical interlock, Double Tongue and Groove for enhanced airtightness in cold storage, Hidden Tongue and Groove (concealed-fix) for premium aesthetics, and M-Section joint. Joint selection depends on insulation requirement, aesthetics, and wind load.

A complete Alfaa PUF roof installation requires gable-end flashing, end-wall flashing, ridge flashing, eave gutter (box or open type), self-drilling screws with EPDM washers, ridge caps, and sealant or foam filler for joint gaps. Alfaa supplies all branded accessories matched to panel profile and colour, ensuring a weatherproof and aesthetically consistent roof system.

Standard PUF panels have limited fire resistance. For projects requiring fire-rated insulation, Alfaa Panels recommends PIR (polyisocyanurate) panels or Rockwool sandwich panels which offer superior fire resistance. Our team will recommend the right product based on your fire safety requirement and local building codes.

Alfaa Panels operates 7 fully automated PUF sandwich panel manufacturing plants across India, with headquarters in Koramangala, Bengaluru, Karnataka. With a combined monthly production capacity exceeding 10 lakh+ square metres, Alfaa is India’s largest sandwich panel manufacturer and delivers to all 4 corners of India.
