Anhydritec Gyvlon Thermio Plus Screed

A pumpable self-smoothing, flowing screed manufactured to BS EN 13813. It is specifically designed to complement both water underfloor heating and cooling systems.

Features and benefits:

• Guaranteed thermal performance.
• Excellent thermal conductivity.
• Coupled with an underfloor heating or cooling system guarantees a pipe encapsulation and an emitter.
• Up to 30% increase of the thermal value coefficient for maximized performance of the underfloor heating system.
• Up to 80% thermal diffusivity for a much faster ramp-up in temperature, greatly improving immediate and long term comfort.
• Up to 8% savings on heating bills.
• Very high fluidity for fast installation.
• Easily achieves SR2 finish as described in BS 8204.
• Extremely low shrinkage - does not curl and minimizes the risk of cracking.
• Maximum bay size of 300 m².
• Avoids the need for reinforcement and no need for a curing membrane (self-curing).
• Environmentally friendly – 98% recycled content, 100% recyclable.
• Low inertia.
• Self-compacting.
• Protein free.

Product Options:

Sub base:

Gyvlon screeds are suitable for application to most types of sub bases, demonstrating an excellent degree of dimensional stability (maximum shrinkage/ expansion on drying of 0.02%) when compared to traditional sand/ cement based screeds.

Application thickness (minimum):

• Unbonded: 30 mm.
• Floating residential: 35 mm.
• Floating commercial: 40 mm.
• Underfloor heating: 20 mm (nominal).
