Thermoplane
Thermoplane is a specially formulated blend of calcium sulphate screed binder, sand, clean water and special additives to produce a highly fluid, thermally efficient flowing screed. Due to its formulation and additives, Thermoplane achieves a higher than standard strength of C35/F7 making it ideal for use over suitably engineered timber joists, providing a concrete feel to the floor and allowing the Thermoplane pipes to be placed in thermally efficient screed rather than the beneath inefficient timber.

Thinner minimum depth/Higher conductivity
Thermoplane has a significantly higher thermal conductivity than sand cement screeds and timber, coupled with its self compacting ability which eliminates air entrapment and thinner overall screed depth, (Minimum 25mm nominal 30mm cover to the pipes) leads to a more energy efficient and responsive screed.
| Product | Thermal Conductivity | Depth | Thermal Resistance |
|---|---|---|---|
| Thermoplane | 2.2W/mK2 | 45mm | 0.0205W/Mk |
| Sand Cement Screed | 1.1W/mK2 | 75mm | 0.0682W/Mk |
| Timber Board | 0.15W/mK2 | 18mm | 0.1200W/Mk |

Speed
As with all Gypsol flowing screeds, Thermoplane is pumped in to place and finished by fully trained installers, making the process a fast, smooth and well audited with areas of up to 2000m2 possible in one day compared with a typical sand cement screed team which can manage an average of just 150m2 per day. In addition to the installation itself, Gypsol is also self curing and has a very early strength gain, making it ready for light foot traffic in 24-48 hours and loading after just 7 days, compared to 7 and 28 days respectively for conventional sand cement screeds.
Larger bays with UFH (300m2 vs 36m2) – As with all screeds Thermoplane will require expansion joints however Thermoplane has a minimal thermal expansion of 0.012mm/mK, meaning larger bays can be created over underfloor heating eliminating the need for as many costly joints which then need reflecting in the floor covering.
| Thermoplane | Sand Cement | |
|---|---|---|
| Maximum Bay Size | 300m2 | 36m2 |
| Maximum Bay Length | 20m | -- |
| Maximum Aspect Ratio | 6:1 | -- |
Less shrinkage
Thermoplane also has a lower shrinkage profile than conventional cement based screeds making it more resilient to cracking and eliminated edge curling, although more resilient Thermoplane should still be installed in a well sealed and prepared building to protect it from through drafts and water ingress, further details can be found at www.gypsol.co.uk
Better surface finish
As with all Gypsol screeds Thermoplane is installed as a highly fluid mix, allowing the trained installer able to achieve a higher level of surface finish and surface regularity than you would expect from a sand cement screed, this is beneficial as it can reduce/eliminate the need for further smoothing compounds dependant on your choice of floor finishes.
Increase recycled content
All Gypsol screeds are based on Gypsum calcium sulphate binder instead of cement, Gypsol binder is manufactured from a synthetic anhydrite which is an industry by product making the binder element 99% recycled compared to the 1.6 tonnes of raw material required to make 1 tonne of cement, in addition to recycled content our binder manufacture only generates around 40 degrees of heat, where cement production requires upwards of 1400 degrees greatly increasing the embodied energy.
Health and Safety
As with all Gypsol screeds, Gypsol is installed as a fluid material through a screed pump meaning very little manual handling is required and no exposed mechanical plant is present, the installation of the screed is done standing up removing the need for labour to crouch on their hand and knees for hours at a time all but eliminating the negative impact on the body associated with dry screed.
