SOPREMA - DuO HT 4 SLATES/F C180 FC

DuO HT 4 SLATES/F C180 FC | Dual-Modified TPO/SBS Waterproofing Membrane

The DuO HT 4 SLATES/F C180 FC is a premium flexible membrane featuring revolutionary dual technology. By combining TPO-modified bitumen on top and SBS-modified bitumen underneath, this membrane delivers the ultimate balance of superior UV resistance and exceptional adhesion, guaranteeing a watertight, long-lasting roof.

Key Performance Benefits:

• Dual-Layer Strength: The upper TPO-modified coating provides high mechanical strength and UV resistance, while the SBS undercoating ensures high elasticity and an aggressive bond.
• Built-in Stability: Features a robust composite reinforcement (polyester & glass fibre 180 g/m2) to prevent shrinking and guarantee exceptional dimensional stability.
• Perfect Seam Integrity: The generous $8\text{ cm}$ selvedge is coated with SBS modified bitumen to ensure an ideal SBS-SBS seal, making application easier and joints perfectly sealed.

• Durable Finish: Finished with an optimally pressed-in mixture of black and anthracite granules, providing aesthetic appeal and excellent long-term surface protection.

Full Technical Product Description: 

DuO HT 4 SLATES/F C180 FC is a flexible waterproofing membrane with a dual reinforcement and a double polymeric bitumen coating. The upper
coating consists of TPO (Thermoplastic PolyOlefins) - modified bitumen,
resulting in a high mechanical and UV resistance. The undercoating consists of SBS (Styrene Butadiene Styrene) - modified bitumen with high elasticity and strong adhesion properties. The composite reinforcement of polyester & glass fibre (180 g/m²) combine to provide strenght and stability. The upper side is finished with an optimally pressed-in mixture of black colored and anthracite granules and the underside is covered with a sacrificial film. The selvedge with a width of 8 cm is coated with SBS modified bitumen to ensure an SBS-SBS seal. This provides an easy application technique and perfectly sealed joints.
