Choosing the right insulation for Saudi Arabian projects is a critical decision impacting energy efficiency, construction timelines, and long-term maintenance. As ThermalPlaster experts, we frequently encounter specifiers weighing our solution against traditional Mineral Wool (Rockwool/Glasswool) Panels.
This comparison highlights key factors to help architects and engineers justify their choice:
Key Performance Differentiators
| Feature | ThermalPlaster (Perlite-based) | Mineral Wool Panels (Rockwool/Glasswool) | Strategic Advantage (KSA Context) |
|---|---|---|---|
| Application | Monolithic (Spray/Trowel applied) | Panel-based (Fixed with adhesive/mechanical fasteners) | Ease and Speed: Quicker application, especially on curved or complex facades. Eliminates panel gaps. |
| Thermal Bridging | None. Seamless, continuous layer. | High Risk. Occurs at panel joints and fastener points if installation is imperfect. | Superior Efficiency: Ensures zero thermal leaks, crucial for reducing extreme AC loads. |
| Fire Performance | Non-combustible (Class A1). Inherently fireproof. | Non-combustible (Class A1). Highly fire-resistant. | Equally High Safety: Both offer top-tier fire protection, meeting stringent KSA requirements. |
| Durability & Impact | Robust. Integral part of the wall system; high compressive strength. | Fragile. Susceptible to damage from impact or handling before finishing. | Long-Term Resilience: Handles construction site and structural movement better; less maintenance risk. |
| Moisture Management | Breathable. Allows vapor transmission, preventing trapped moisture. | Low Breathability. Can trap moisture if the wall system is not perfectly designed/sealed. | Prevents Mildew: Essential for coastal or high-humidity regions. |
