Continuous Sandwich Roof Panel
(SFPL-RP-2005)

Our Continuous Sandwich Roof Panels are engineered for uninterrupted, leak-resistant roof coverage with high thermal efficiency and structural strength. Designed for long spans, minimal joints, and excellent insulation, they’re ideal for industrial, commercial, and cold chain roofing applications. These panels are manufactured using high-density PUF or PIR core, bonded between durable outer skins like PPGL, Bare GL, or PVDF, offering both performance and aesthetic appeal.

The advanced interlocking joint and slope-compatible profiles ensure quick installation, low maintenance, and protection against water ingress, corrosion, and heat gain.

FAQS

Q1. What is a Continuous Sandwich Roof Panel?
It is a long-span insulated roofing panel with minimal joints, used for thermal and weather protection across industrial and commercial structures.
Q2. Can it be used in rainy or coastal regions?
Yes. The interlocking ridge joint system prevents water leakage and resists corrosion with marine-grade finishes like PVDF or Aluminium.
Q3. How long can these panels be?
Standard lengths go up to 12 meters, and longer spans are available upon request for large roof systems.
Q4. Does it support solar panel mounting?
Yes, with proper framing or purlin integration, they support rooftop solar systems without compromising the insulation.
Q5. Are these suitable for walkable roofs?
For walkability, high-strength skins and support structures can be integrated—consult us for reinforced options.
