Topflow Screed A Thermio | Liquid Screeds / Free-Flowing Screeds / Gyvlon Screeds

Topflow Screed A Thermio

The guaranteed ultra-efficient liquid screed / free-flowing / gyvlon screed for underfloor heating systems.

Product Description

Thermio+, anhydritec environmental liquid screed solution, has been developed to further improve underfloor heating systems by creating the first liquid / gyvlon screed specifically designed to complement both water underfloor heating and cooling systems.

Features & Benefits of Topflow Liquid Screed A Thermio

Topflow Liquid Screed A Thermio+ is the only liquid screed with a guaranteed thermal performance.
This technology coupled with an underfloor heating or cooling system guarantees pipe encapsulation and an emitter which will give;

  • Performance – up to 30% increase in the thermal emission value for maximised performance of the underfloor heating system once your Gyvlon Screed is installed.
  • Comfort – up to 80% thermal diffusivity for a much faster ramp-up in temperature, greatly improving immediate and long term comfort
  • Savings – up to 8% savings on heating bills
  • Programme efficiency – 20 day reduction in screed drying times when compared to conventional flowing screeds
  • All the normal benefits of Topflow Screed A liquid screed / Gyvlon screed products
  • Very high fluidity for fast installation of your liquid screed
  • Minimum SR2 surface finish
  • Greatly reduced cracking and no curling
  • Maximum bay size 300m2
  • No reinforcement
  • No need for a curing membrane
  • Typically 36% recycled content

Thermal Performance

  • High and guaranteed thermal performance both in heating or cooling modes
  • Low inertia (nominal thickness 20mm cover to pipes)
  • Red colouration – the guarantee of the right product by Gyvlon Screeds

Outstanding Performance

Topflow Screed A Thermio+ liquid screed / gyvlon screeds is extremely beneficial for your water underfloor heating systems

  • Enables a much faster rise in temperature thanks to its high thermal diffusivity (up to 80% more than a cement screed), providing quicker response to thermostat changes.
  • Greatly improved comfort as the liquid floor emits the heat in a more efficient and homogeneous way thanks to the exceptional thermal emission value of the liquid screed – up to 30% more, maximising your underfloor heating performance
  • Allows your boiler or heat pump to work with greater efficiency therefore creating considerable savings on your heating bill of up to 8%
