Sikaplan® TB-15 | High Dimensional Stability FPO Roof Waterproofing Membrane

Long-Lasting FPO Roofing Membrane with Superior Dimensional Stability

Sikaplan® TB-15 is a multi-layer FPO-based roof waterproofing membrane reinforced with glass fiber, compliant with the EN 13956 standard. With a thickness of 1.5 mm, it provides high dimensional stability thanks to its glass fiber reinforcement, minimizing expansion and contraction movements caused by temperature changes.

This feature provides a significant advantage in long-term performance, especially in large-area and ballasted roof systems where dimensional stability is critical.

Why Choose Sikaplan® TB-15?

✔ Glass Fiber Reinforcement – Provides excellent dimensional stability
✔ 1.5 mm Thickness – Offers enhanced mechanical strength and durability
✔ Permanent UV Resistance – Ensures long service life in exposed roof applications
✔ Root Resistant (FLL Certified) – Suitable for green roof systems
✔ Compatible with Existing Bitumen Layers – Ideal for renovation projects
✔ Flame-Free Installation – Safe joining with hot air welding technology

Where Is Sikaplan® TB-15 Used?

Sikaplan® TB-15 is especially suitable for:

Ballasted roof systems (aggregate or concrete-covered roofs)
Inverted roof applications
Green roof and landscaped roof systems
Walkable terrace roofs
Large-scale commercial roofing projects

Thanks to its glass fiber reinforcement, the membrane maintains its shape and performance over time, making it particularly advantageous in regions with significant temperature variations.

Sikaplan® TB-15 vs. Sikaplan® TM-12

Sikaplan® TM-12

Polyester reinforced membrane
Designed mainly for mechanically fixed roof systems
Suitable for lightweight roofing solutions

Sikaplan® TB-15

Glass fiber reinforced membrane
Designed for ballasted roof systems and applications requiring high dimensional stability
Ideal for green roofs and large-area roofing projects

For ballasted roofs, green roof systems, or projects where dimensional stability is a priority, Sikaplan® TB-15 is the recommended solution. For mechanically fixed systems requiring a lighter structure, Sikaplan® TM-12 may be a more suitable choice.
