Painel de telhado com isolamento em PIR e PU
Description
Glostar’s PIR PU insulated roof panel is a screw-connected, factory-prefabricated roofing panel with tight side-lap overlapping for fast, reliable on-site installation. A distinctive capillary groove design at each joint effectively channels away rainwater infiltration and interrupts cold-bridge formation, protecting the building’s thermal performance while significantly lowering construction costs. The panel profile supports roof pitches as low as 3%, giving designers flexibility on low-slope industrial and commercial roofs.
Why Choose Glostar PIR PU Roof Panel?
Glostar’s insulated roof panels combine strong thermal insulation with reliable load-bearing capacity. Clients can select panel thickness based on the span, design load, and climate requirements of their project.
The thicker the panel, the better its insulation performance: a 30mm panel has a heat transfer coefficient of 0.32 W/m²K, while a 150mm panel drops to just 0.11 W/m²K. Under identical conditions, the thicker panel conducts far less heat, keeping indoor temperature more stable against outdoor swings.
Thicker panels also allow a larger structural span under the same load, reducing the number of purlins and structural components required. This gives architects and engineers more freedom to design larger, uninterrupted roof spans.

Advantages
High Rigidity
The high-strength core keeps the panel rigid and resistant to deformation, allowing it to carry heavier loads and improving overall roof stability and safety.
Strong Wind Uplift Resistance
An optimized structural profile gives the roof panel strong resistance to negative air pressure, effectively withstanding strong wind loads and preventing roof damage.
Tight Overlap, Fast Installation
Factory-prefabricated panels install quickly on site, shortening the construction schedule and improving overall project efficiency.
