Sikaplan G-15

Sikaplan G-15 | Mechanically Fixed PVC Roof Waterproofing Membrane

Thicker, Stronger and Longer-Lasting Roofing Solution

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.

Key Advantages of Sikaplan® G-15

✔ 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

Where Is Sikaplan® G-15 Used?

Sikaplan® G-15 is suitable for:

  • Industrial facility roofs
  • Shopping malls and commercial buildings
  • Warehouses and logistics centers
  • Areas exposed to high wind loads
  • Projects requiring extended service life

Especially in large-scale roofing projects, Sikaplan® G-15 provides additional investment security with its superior durability and long-term performance.

Why Choose Sikaplan® G-15 Instead of G-12?

Sikaplan® G-15 is the preferred solution when:

  • The project is located in a high wind-load area
  • Long-term durability is a priority
  • The roof system has large spans
  • Higher mechanical resistance is required

For projects with lower mechanical requirements where cost optimization is the main objective, Sikaplan® G-12 may be considered. However, when maximum durability, safety, and long-term performance are required, Sikaplan® G-15 provides a stronger roofing solution.
