What is a Sandwich Roof PUF Panel?
A Sandwich Roof PUF Panel is a high-performance insulated roofing panel consisting of three layers bonded together under pressure:
- Top Sheet: Pre-coated galvanized steel (PPGI) — profiled for structural rigidity and weather resistance
- Core: Rigid Polyurethane Foam (PUF) — closed-cell insulation with excellent thermal performance
- Bottom Sheet: Pre-coated galvanized steel — flat or lightly profiled inner facing
This three-layer sandwich construction creates a roofing panel that is structurally strong, thermally efficient, lightweight, and weather-resistant — making it the most preferred industrial roofing solution across India. Metro PUF Industries manufactures Sandwich Roof PUF Panels in 30mm and 50mm thickness to meet all project requirements.
Key Features & Benefits
Excellent Thermal Insulation
PUF core significantly reduces heat transfer, keeping factory and warehouse interiors cooler and reducing AC costs by up to 30%.
Lightweight Construction
Despite high strength, panels are lightweight — reducing dead load on the building structure and foundation.
Fast Site Installation
Tongue-and-groove interlocking profile enables rapid assembly, cutting roofing time significantly vs conventional methods.
Superior Weather Resistance
Pre-coated galvanized steel outer sheet resists heavy rain, UV radiation, and corrosion for decades of maintenance-free performance.
Acoustic Insulation
PUF core absorbs impact and airborne noise, reducing rain noise and external sound transmission into the building.
Eco-Friendly
Energy savings from superior insulation reduce the building carbon footprint over its entire lifetime.

Frequently Asked Questions
What is the difference between Sandwich Roof PUF Panel and a regular roofing sheet?
A regular colour coated roofing sheet provides only weather protection with no thermal insulation. A Sandwich Roof PUF Panel includes a PUF insulation core between two steel sheets, providing both structural roofing and thermal insulation in a single panel — significantly reducing heat inside the building.
What thickness of Sandwich Roof PUF Panel should I use for a warehouse?
For standard warehouses and industrial buildings, 30mm Sandwich Roof PUF Panels are sufficient and most cost-effective. For cold storage, pharmaceutical, or high-heat environments, 50mm panels are recommended for maximum thermal efficiency.
How are Sandwich Roof PUF Panels installed?
Panels are installed on purlins (C or Z section steel supports) using self-drilling screws. The tongue-and-groove interlocking profile ensures a weatherproof joint between panels. Installation is significantly faster than conventional roofing methods.
How long does a Sandwich Roof PUF Panel last?
With proper installation and standard maintenance, Sandwich Roof PUF Panels from Metro PUF Industries last 20 to 30 years. The pre-coated galvanized steel facings provide long-term resistance to corrosion, UV, and weathering.
What is the weight of a Sandwich Roof PUF Panel?
A standard 30mm Sandwich Roof PUF Panel weighs approximately 10–12 kg/m². The lightweight nature of PUF panels reduces structural load compared to heavier conventional roofing materials.
