Painel sanduíche metálico impermeável com isolamento térmico para telhado
The Waterproof Metal Thermal Insulated Sandwich Panel for Roof (featuring the SR1000 deep-rib profile) is a high-end composite roofing solution engineered for modern industrial and commercial buildings. Designed to seamlessly integrate superior thermal efficiency, flawless waterproofing, and robust load-bearing capabilities, this system combines a durable metal face with a high-density insulating core.
Through advanced manufacturing equipment, the outer steel plate is composited with premium insulation, successfully resolving the common industry problem of separating roofing insulation from waterproofing. Its unique deep-rib design ensures rapid water drainage, while the advanced PU side-sealing technology provides a sturdy, flat installation base—making it fully compatible with rooftop photovoltaic (solar) modules. It is the preferred enclosure solution for green, energy-efficient construction.
Description
Insulated metal sandwich panels for roofing are prefabricated roofing system components often paired with TPO waterproofing membranes to create the “SR1000+TPO” roofing solution. This solution is primarily designed for industrial and civil construction projects that demand high standards for waterproofing, thermal insulation, and construction efficiency.

Within Glostar’s roofing product portfolio, the SR1000 Metal Thermal Insulated Roof Panel —alongside the PVR1000 and MR468—forms a systematic line of insulated metal roofing products, offering customers a diverse range of building envelope system options.
Roof Sandwich Panel Joint & Connection Options

Key Performance Features
- Superior Waterproofing: Engineered with a specially designed overlap joint and a high-profile, deep-rib structure that prevents water pooling and completely eliminates leakage risks, even during extreme rainfall.
- Excellent Thermal Insulation: The high-quality core material significantly reduces heat transfer, maintaining consistent indoor temperatures and heavily reducing energy consumption for heating and cooling.
- Class-A Fire Resistance: Available with fire-rated, non-combustible core materials (such as Rockwool or Glasswool) to meet and exceed strict international fire safety standards.
- High Strength & Durability: Reinforced with high-tensile galvanized or galvalume steel sheets, delivering outstanding resistance to heavy wind loads, severe weather, and long-term corrosion.
- Fast & Cost-Effective Installation: The intelligent, lightweight modular design allows for rapid on-site assembly, effectively cutting construction time and labor costs by up to 40%.
- Aesthetic Appeal: Fully customizable in a wide variety of RAL colors and premium surface coatings (PE, PVDF, HDP) to match your specific architectural vision.

Frequently Asked Questions
How does this sandwich panel achieve waterproofing?
Are these panels compatible with rooftop solar (PV) systems?
Yes! The deep-rib profile (like the SR1000 system) is specifically designed to accommodate standard solar mounting clamps. This allows you to securely install photovoltaic panels directly onto the ribs without penetrating the steel sheet, preserving the roof’s waterproof integrity.
Which core material should I choose: Rockwool or Fiberglass Wool?
What is the lifespan of these insulated metal roof panels?
Can the panel lengths and colors be customized?
