PETRAFAS-34 PLUS A new standard of durability in ETICS systems | 05.05.2026
We are constantly improving our solutions for modern construction, as evidenced by our newest product – the PETRAFAS-34 PLUS stone wool panel. This product is designed for the most demanding non-ventilated facades in ETICS systems. It combines excellent thermal insulation properties, confirmed by a thermal conductivity coefficient of 0.034 W/mK, with unprecedented structural robustness, setting new standards in building facade protection.
A key advantage of the new panel is its exceptional tensile strength perpendicular to the surface, at least 10 kPa. In practice, this means that each square meter of insulation can support a load of 1000 kg, guaranteeing maximum stability of the entire insulation system. Thanks to this high TR parameter, the facade becomes highly resistant to delamination of the insulation layer structure and mechanical damage, retaining its original form and properties for decades.
