Sikaplan® G-15 is a 1.5 mm thick PVC-based roof waterproofing membrane reinforced with polyester, manufactured in compliance with the EN 13956 standard. Designed for mechanically fixed roof systems, it provides maximum performance on large-span roofs exposed to high wind loads.
Compared to Sikaplan® G-12, its increased thickness provides higher mechanical strength, improved impact resistance, and a longer service life, making it an ideal choice for demanding roofing projects.
✔ Enhanced Mechanical Strength – 1.5 mm thickness provides higher resistance against impact and tearing ✔ High Wind Resistance – Ensures reliable performance in mechanically fixed roofing systems ✔ Long-Term UV Resistance – Provides durable protection against solar radiation ✔ High Water Vapor Permeability – Helps maintain moisture balance and reduces condensation risks ✔ Easy Welding Application – Enables secure and homogeneous joints with hot air welding technology ✔ Recyclable Structure – Supports environmentally responsible building solutions
Sikaplan® G-15 is suitable for:
Especially in large-scale roofing projects, Sikaplan® G-15 provides additional investment security with its superior durability and long-term performance.
