What is a Sandwich Wall PUF Panel?
A Sandwich Wall PUF Panel is a high-performance insulated wall cladding panel consisting of three layers bonded together under controlled pressure:
- Outer Sheet: Pre-coated galvanized steel (PPGI) — flat or lightly ribbed for a clean, professional wall finish
- Core: Rigid Polyurethane Foam (PUF) — closed-cell insulation providing excellent thermal performance
- Inner Sheet: Pre-coated galvanized steel — smooth finish for hygienic interior wall surfaces
The three-layer construction delivers a wall panel that is thermally efficient, structurally rigid, lightweight, and easy to install — making it the preferred wall solution for cold storage units, industrial factories, pharmaceutical plants, and clean rooms across India. Metro PUF Industries manufactures Sandwich Wall PUF Panels in 30mm and 50mm thickness to meet all project needs.
Key Features & Benefits of Sandwich Wall PUF Panel
Superior Thermal Insulation
PUF core minimizes heat transfer through walls, maintaining stable interior temperatures and reducing energy costs significantly.
Moisture & Vapour Resistant
Closed-cell PUF foam resists moisture penetration — essential for cold storage, food processing, and pharmaceutical environments.
Smooth Hygienic Surface
Pre-coated steel inner facing provides a smooth, cleanable surface meeting GMP and food-safety hygiene requirements.
Fast Installation
Tongue-and-groove interlocking panel edges enable rapid wall assembly, reducing labour time and construction costs.
Sound Insulation
PUF core significantly reduces sound transmission through walls — ideal for factories, offices, and noise-sensitive environments.
Durable & Long-Lasting
Pre-coated galvanized steel facing resists corrosion, scratches, and weathering for 20–30 years of maintenance-free service life.

Frequently Asked Questions
What is a Sandwich Wall PUF Panel?
A Sandwich Wall PUF Panel is an insulated wall cladding panel made of two pre-coated steel sheets with a rigid Polyurethane Foam (PUF) core bonded between them. It is used for factory walls, cold storage rooms, clean rooms, and industrial partitions requiring thermal insulation and a hygienic surface finish.
What is the difference between Sandwich Wall PUF Panel and Sandwich Roof PUF Panel?
Sandwich Wall PUF Panels have flat or lightly ribbed facings designed for vertical wall applications with a smooth, hygienic interior surface. Sandwich Roof PUF Panels have a corrugated profiled top sheet designed to handle roof loads and facilitate rainwater drainage.
What thickness should I choose for cold storage walls?
50mm Sandwich Wall PUF Panels are strongly recommended for cold storage and freezer room walls as they provide maximum thermal insulation, minimize energy consumption, and prevent moisture ingress into the insulation core.
Are Sandwich Wall PUF Panels suitable for clean rooms?
Yes. The smooth, pre-coated steel inner surface of Sandwich Wall PUF Panels is non-porous, easy to sanitize, and resistant to chemicals — making it suitable for pharmaceutical clean rooms, food processing environments, and GMP-compliant manufacturing facilities.
How long do Sandwich Wall PUF Panels last?
With proper installation and standard maintenance, Sandwich Wall PUF Panels from Metro PUF Industries last 20 to 30 years. The pre-coated galvanized steel facings provide long-term resistance to corrosion, moisture, and wear.
