PUF Wall Panels
Sandwich wall panels are engineered insulated panels comprising a high-performance polyurethane foam (PUF) core bonded between metal facings. These panels provide stable thermal insulation and consistent performance across varying operating conditions.
Manufactured by Mount Roofing & Structures, the lightweight and rigid construction supports faster installation, reduced structural load, and efficient long-term building performance.
Colour-Coated Finishes
Sandwich wall panels are supplied with a standard colour-coated finish selected to meet functional zoning, architectural coordination, and environmental exposure requirements. The pre-coated metal facings are factory-finished to ensure uniform colour consistency, corrosion resistance, and long-term surface stability under industrial and coastal operating conditions.

Advantages of the Wall Panels
Integrated Wall & Insulation System
PUF wall panels act as both the external cladding and thermal insulation layer, reducing the need for separate masonry, plastering, and insulation assemblies.
Faster Building Enclosure
Large-format factory-fabricated panels enable quicker vertical enclosure of industrial and commercial structures compared to conventional wall construction methods.
Reduced Foundation Load
Lightweight insulated wall systems impose lower loads on foundations than traditional brick or concrete walls, supporting more efficient structural planning.
Controlled Internal Finishes
Pre-finished metal surfaces reduce the need for additional surface treatments in many industrial and warehouse applications.
Modular Expansion Flexibility
Panelized wall systems allow easier future extensions or internal layout modifications in steel building structures.

Frequently asked Question
PUF wall panels are prefabricated building envelope systems made using a rigid polyurethane foam (PUF) core bonded between two profiled metal sheets. These panels are specifically engineered to provide superior thermal insulation, structural strength, and quick installation for industrial, commercial, and controlled-environment buildings such as cold storages, cleanrooms, factories etc.
Sandwich PUF wall panels offer lower heat transfer, faster installation, and reduced structural load compared to brick or block walls, making them more efficient for industrial and controlled environments.
Thermal performance is governed by core density, panel thickness, joint detailing, and installation quality, with system design playing a critical role alongside material selection.
Yes. Properly specified panels maintain stable internal conditions for cold storage, cleanrooms, data centres, and food processing units by limiting heat gain and air infiltration.
Panels are engineered to align with steel framing systems, allowing direct fixing, controlled tolerances, and rapid enclosure without secondary wall construction.
Joint design influences airtightness, thermal continuity, and condensation control, directly impacting long-term enclosure efficiency.
For industrial wall applications, sandwich panels are commonly specified in 40 mm, 50 mm, 60 mm, and 80 mm thicknesses. Selection depends on internal temperature requirements, climatic exposure, and energy performance targets, with higher thicknesses typically used for temperature-controlled or high-performance facilities.
Factory-manufactured panels reduce wet works, enable parallel construction activities, and significantly shorten on-site installation timelines.
When correctly specified and installed, sandwich wall panels deliver long-term dimensional stability and consistent insulation performance over the building lifecycle.
By lowering HVAC demand, reducing thermal losses, and minimizing maintenance compared to conventional wall systems, panels help achieve measurable energy savings.
Key considerations include thermal performance, joint integrity, fire behaviour, structural span capability, and integration with the overall building envelope system.
