Advantages of the Roof Panels
Optimized Building Envelope Performance
PUF roof panels function as a combined insulation and external roofing system, reducing the need for multi-layer construction and simplifying roof assembly.
Reduced Structural Load
Lightweight insulated panels reduce dead load on primary steel members compared to conventional RCC or built-up roofing systems, allowing more efficient structural design.
Controlled Installation Process
Factory-manufactured panels enable predictable on-site installation timelines with reduced wet works and minimized construction dependency on weather conditions.
Improved Long-Term Thermal Stability
The rigid polyurethane core supports consistent insulation performance across industrial roof spans when properly installed and sealed.
Lower Maintenance Exposure
Pre-finished metal facings reduce surface degradation risks associated with conventional roofing materials under typical industrial environments.

Frequently asked Question
Sandwich roof panels are factory-engineered roofing systems consisting of insulated cores bonded between profiled metal facings, designed to deliver structural performance, thermal insulation, and weather protection as a single integrated roof element.
Mount’s sandwich roof panels integrate insulation, structural performance, and weather protection into a single factory-manufactured system, enabling faster installation and consistent performance. Unlike traditional roofing, which relies on multiple site-installed layers, they reduce dependency on workmanship, minimize leakage risks at joints, and deliver more uniform thermal insulation.
By limiting roof-level heat ingress and reducing thermal bridging, sandwich roof panels lower peak internal temperatures and HVAC demand, contributing to measurable reductions in energy consumption.
Yes. Their high stiffness-to-weight ratio enables longer clear spans while maintaining performance under wind uplift and service loads, reducing the need for secondary steel support.
Water tightness is ensured through precision-formed overlaps, engineered fixing zones, and controlled joint geometry designed to resist wind-driven rain and moisture penetration.
Sandwich roof panels are widely used in cold storage, pharmaceutical, and food processing facilities where roof-level thermal stability and condensation control are critical.
The insulated core significantly reduces radiant heat transfer from roof surfaces exposed to direct solar gain, maintaining stable internal conditions in hot and mixed climates.
Mount’s sandwich roof panels are available in insulation thicknesses ranging from 20mm – 200mm, allowing thermal performance to be engineered based on climatic conditions, energy targets, and specific building applications defined during project design.
Factory-fabricated panels reduce on-site assembly steps, enabling faster installation, improved accuracy, and earlier building enclosure.
When correctly specified and installed, Mount’s sandwich roof panels deliver long-term structural and thermal performance with minimal maintenance over their design life.
