FAQ’S
With 35+ years in the industry, we’re known for our high-quality products and excellent customer service.
A PUF roof panel is an insulated sandwich roofing panel with a rigid polyurethane foam (PUF) core bonded between two steel sheets. The profiled outer sheet carries structural loads and resists weather, while the PUF core delivers thermal insulation. ALFAA Panels manufactures and supplies PUF roof panels for industrial and commercial roofing across South India.
It has 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. ALFAA sources steel facers from JSW Steel, Tata Steel, AMNS and Hindalco for consistent quality in every panel.
They are used for cold storage roofs, food processing plants, industrial warehouses, pre-engineered buildings (PEB), pharmaceutical plants, logistics parks, data centres, poultry farms, dairy facilities, educational institutions, sports facilities and commercial buildings. ALFAA supplies PUF roof panels for all these applications across Tamil Nadu, Karnataka, Kerala, Telangana, Andhra Pradesh and Puducherry.
ALFAA Panels is a leading PUF panel brand in India and a trusted supplier across South India. With 35+ years of experience, 7 fully automated manufacturing plants and monthly capacity exceeding 10 lakh+ square metres, ALFAA delivers panels using steel from JSW, Tata Steel, AMNS and Hindalco, with CFC/HFC/HCFC-free foam, custom lengths up to 12,000mm and fast pan-India delivery.
30mm, 40mm, 50mm, 60mm, 80mm, 100mm and 120mm. 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 standard. In hot South Indian climates such as inland Tamil Nadu, Telangana and Andhra Pradesh, a minimum of 60–80mm is advised to limit heat ingress.
Yes. ALFAA PUF roof panels are fully waterproof when installed with correct joint sealing, EPDM-washered fasteners and proper flashing — ridge flashing, gable-end flashing and eave gutters. The closed-cell PUF core does not absorb moisture, so the roof performs without leakage even through heavy South-West and North-East monsoon rainfall.
ALFAA PUF panels are designed for 20–30 years of service with minimal maintenance. Longevity depends on facer material — PPGL Galvalume outperforms PPGI in coastal Kerala and Andhra environments — plus correct installation and periodic inspection of joints and flashings. The PUF core itself does not degrade under normal conditions.
Roof panels have a trapezoidal or standing-seam profiled top sheet 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, so wall panels should not be used as roof panels. ALFAA manufactures both as separate, purpose-built products.
Standard colours are Sky Blue, Off White, Mist Green, Brick Red, Graphite Grey and Dark Grey for both PPGI and PPGL facers. Custom RAL colours are available for project orders. Top-coat painting thickness is 18–22 microns with SMP, PVDF or RMP finish options.
Pricing depends on panel thickness (30mm–120mm), facer type (PPGI being most economical; PPGL, SS and aluminium being premium), steel gauge, project quantity and site location. For accurate pricing for your project in Tamil Nadu, Karnataka, Kerala, Telangana, Andhra Pradesh or Puducherry, request a quote at www.alfaapanels.com or call 09606914181. Bulk and supply-and-install packages are available.
Through a fully automated continuous process — steel coils are unwound, surface-cleaned and heated for adhesion; a 5-component PU foam mix is injected automatically; panels pass through a high-pressure heated steel-belt press; then they are cut to custom lengths, cooled, stacked and packaged. This ensures consistent 40±2 kg/m³ foam density in every panel with zero manual error.
Five joint systems — Standard Roof Joint for cost-effective applications, Single Tongue and Groove for a secure mechanical interlock, Double Tongue and Groove for enhanced airtightness in cold storage, Hidden Tongue and Groove (concealed-fix) for premium aesthetics, and the M-Section joint. Selection depends on insulation, aesthetics and wind load.
A complete installation needs 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 your panel profile and colour for a weatherproof, consistent roof system.
Standard PUF panels have limited fire resistance. For fire-rated requirements, ALFAA recommends PIR (polyisocyanurate) or Rockwool sandwich panels for superior fire performance. Our team will recommend the right product for your fire-safety needs and local building codes.
ALFAA operates 7 fully automated PUF sandwich panel manufacturing plants across India, headquartered in Koramangala, Bengaluru, Karnataka. With combined monthly capacity exceeding 10 lakh+ square metres, ALFAA delivers across all of South India and the rest of the country. Contact: sales@alfaapanels.com or 09606914181.
