Technical FAQ

A PUF (Polyurethane Foam) panel is a sandwich-type construction material consisting of a rigid foam core bonded between two metal skins. It provides superior thermal insulation and structural strength.

It is called a sandwich panel because of its layered architecture: Metal Skin + PUF Core + Metal Skin, fused together during manufacturing.

They are widely used in industrial warehouses, factory sheds, cold storage units, clean rooms, and prefabricated site offices.

Their combination of high thermal resistance (R-value), lightweight design, and rapid installation makes them ideal for large-span industrial buildings.

PUF panels offer higher thermal insulation (lower K-value) and better structural rigidity compared to EPS (Expanded Polystyrene) panels of the same thickness.

Yes, they are excellent for terrace sheds, modular homes, and farmhouses where temperature control is a priority.

The R-value measures thermal resistance. A typical 50mm PUF panel has an R-value of approx 14, which is significantly higher than traditional brick walls.

Yes, the density of the PUF core (40kg/m3) effectively dampens external noise, reducing rain noise by up to 25dB.

The industry standard for high-quality panels used in industrial projects is 40kg/m3 (+/- 2kg).

Yes, they significantly reduce energy consumption for air conditioning. Our panels use CFC-free blowing agents.

By acting as a thermal bridge, they prevent the outside heat from entering the building, reducing the load on HVAC systems by up to 50%.

Yes, when installed with anti-capillary grooves and the correct pitch, they provide a 100% waterproof barrier.

Our JSW and TATA sheets feature AZ150 Galvalume coating which provides superior resistance to rust even in humid industrial environments.

We supply PIR (Polyisocyanurate) core panels which are classified as fire-retardant (B1/B2 grade) for high-safety projects.

No, steel and polyurethane foam are non-organic and are resistant to termites, rodents, and fungal growth.

When fixed with recommended SDS screws and purlin spacing, our roofing systems are tested to withstand wind speeds up to 180 km/h.

Yes, being lightweight (approx 10-12 kg/m2), they reduce the weight on the structural frame, allowing for lighter steel trusses.

Absolutely. We supply 100mm to 200mm thick panels specifically designed for walk-in freezers and cold rooms maintaining -20°C.

With basic annual maintenance, high-grade Galvalume sheets from TATA/JSW can last 25-30 years.

We use Silicon Modified Polyester (SMP) and PVDF coatings that are UV-stabilized to prevent fading for over 15 years.

Factors include the sheet thickness (0.5mm is standard), the coating mass (GSM), the insulation core (PUF/XLPE), and the total area.

A thickness of 0.45mm to 0.50mm is the industry standard for industrial sheds for optimal strength and cost.

They use a precision Tongue & Groove joint system that creates an air-tight seal, often further reinforced with industrial sealants.

While possible, it is recommended to use specialized PEB (Pre-Engineered Building) contractors for leak-proof installation.

Verify the GSM of the coating, the thickness of the base metal (BMT), and ensure you get a Manufacturer's Test Certificate (MTC).

Yes, we offer standard T&G, Concealed Bolt systems, and Overlap profiles for different project requirements.

Standard sizes are available in 2-3 days. Customized lengths and colors typically take 7-10 working days.

We can manufacture sheets up to 12 meters in length, limited only by transport constraints.

Yes, for project orders over 10,000 sq ft, our technical team provides onsite measurement and estimation services.

Yes, all our TATA and JSW products come with authorized manufacturer warranties as per their standard terms.

Annual cleaning of gutters, checking for loose fasteners, and removing leaf debris to prevent water stagnation.

A professional inspection is recommended twice a year—pre-monsoon and post-monsoon.

Use plain water and a mild detergent. Avoid high-pressure washers or abrasive scrapers that can damage the paint coating.

Always use recommended touch-up paints to seal the scratch and prevent localized atmospheric corrosion.

Use high-GSM Galvalume (AZ150+) and ensure all cut edges are treated with cold galvanizing spray.

Yes, modularity is a key benefit. Individual panels can be replaced without disturbing the entire roofing system.

Usually, leaks are due to fastener loosening. Tightening the screws or applying industrial-grade MS polymer sealant resolves most joint leaks.

Yes, but only by stepping on the 'valleys' directly over the purlins. Always use safety harnesses and walking boards for large spans.

Often 'rust' is just metal filings from drilling. Clean with soap and a soft brush; if it persists, use a mild automotive polish.

Metal roofs are no more likely to be struck than others, but they are safer because they are non-combustible and can be easily grounded.
