Marley 4mm Talc Torch-on Waterproofing Membrane

Our 4mm Talc Torch-on Rolls, as part of a full torch-on system, are designed to withstand South Africa’s demanding climate, ensuring that both contractors and homeowners have peace of mind knowing their structures are safeguarded against leaks and moisture damage.

Key Benefits of Marley’s 4mm Talc Torch-on Rolls:

Exceptional Elongation (40 / 40): Provides flexibility and strength, ensuring the membrane adapts to building movement and resists cracking.
Cold Flexibility (-10°C): Maintains performance even in colder conditions, reducing the risk of brittleness and premature failure.
Superior Flow Resistance (+120°C): Withstands high temperatures without deformation, ensuring long-term stability and performance.

Why Choose Marley Torch-on?

Trusted quality from a brand with over 70 years of experience in building and roofing materials.
Engineered to provide long-lasting waterproofing protection for flat roofs, balconies and more.
Easy to apply with professional results, giving contractors and property owners confidence in their investment.

IMPORTANT! Talc torch-on rolls always require a protective coating or covering! Either finish with Marley Silver Bitumen Paint, or cover with Marley Mineral Torch-on or a 50mm polystyrene insulation with 19/25mm diameter crush stone combination. Torch-on systems should be inspected every 6 months, as tarnished or defective coverings can expose the talc torch-on to UVA, that will damage the talc membrane, causing it to become brittle and crack.

With Marley’s new Torch-on Waterproofing Membranes, you don’t just cover your roof – you protect your home or project with proven performance and trusted durability.
