Which is the Best Screed for Underfloor Heating

I’m Andy Parkin Managing Director of the Multi-Award Winning Speed Screed. I’m here today to talk about which is the Best Screed for Underfloor Heating.

When we talk about which is the best screed for Underfloor Heating, a few factors may influence your choice.

Here we set out to explore those options, and recommend the most suitable products on the market.

Thermal Conductivity

When looking for the best screed for Underfloor Heating, Thermal Conductivity is an extremely important factor to consider.

The Definition Of Thermal Conductivity Is:

“The Rate At Which Heat Passes Through A Specified Material, Expressed As The Amount Of Heat That Flows Per Unit Time Through A Unit Area With A Temperature Gradient Of One Degree Per Unit Distance”

Flowing screeds have a higher density and therefore lend themselves to greater thermal conductivity.

You may wish to consider the following products to achieve maximum efficiency.

Gypsol HTC
Gyvlon Thermio+
Topflow Screed C Belitex

The Benefits Include:

High Thermal Conductivity
• High Thermal Diffusivity For Fast Heating
• Thinner Screed

Fast Drying

One major consideration when choosing the best screed for Underfloor Heating, is how quickly does it dry so I can lay my floor coverings?

Here we have a number of fast-dry options suitable for underfloor heating use:

• Liquid Screed (Fast Drying Cementitious Belitex) – 14-21 days
• Hydraulic Binder Fast Drying Screeds – 1 day for ceramics, 5 days for resilient
Mapescreed 704 – 7 days for ceramics, 14 days for resilient
Retanol Xtreme – 2 days for ceramics, 3 days for resilient

Foot Trafficking

How soon can you walk on the best screed for underfloor heating? If your program is tight this might be an important consideration.

Below is a selection of screeds that allow for early foot traffic:

Keracem Eco – 8 hrs
Topcem – 12 hrs
Retanol Xtreme – 24 hrs
Calcium Sulphate Screed – 24-48 hrs

If early loading of the screed is required (most screeds achieve their design strength at 28 days), products like Retanol Xtreme have amazing early strength.

Screed Minimum Thickness
If available screed depth is an issue then a thin one might be the best option.

Here we have a selection:

Gypsol HTC – 20mm coverage of the pipes
Gyvlon Thermio+ – 20mm coverage of the pipes
Topflow Screed C Belitex – 30mm coverage of the pipes
Retanol Xtreme – 30mm coverage of the pipes
