Heat and Screed are experts supplying a complete service matching the best hydronic heating systems with the optimal screed for heat transfer, energy savings and environmental impact. Our screeds are free flowing, Gypsol (anhydrite calcium sulphate) screeds. Gypsols properties and performance give our screeds unique advantages compared to cement screeds.
Heat and screed uses Gypsol supplied Anhydrite screed. Gypsol has a 30 year history in producing anhydrite screeds.
Gypsol screed in made up from 98% recycled materials. The production of Gypsol screed productions 92% less CO2 when compared with the production of a ton of cement.
Heat and Screeds anhydrite screed transfers heat from the heating pipes to at a rate of 2.3w/mk. When compared with a standard cement screed which has a transfer rate of 1.1w/mk room will heat up of cool twice as fast as conventional screeds.
Expertise and recognized quality
Our partners in Europe have over 50 years of experience in the formulation of self-levelling screeds, our research and development centre designs innovative products, which benefit a wide range of applications.
Heat and Screed has a full range of fluid screeds, quality controlled and manufactured in our customer’s concrete plants. Ready-to-use, they are then delivered by truck to be pumped and poured on site.
At every stage of the project, from preparation to finishing, we demand strict compliance standards, good practice, technical advice and product recommendations.
For dry interiors a anhydrite screed is used instead of cement variants. Compared to cement a anhydrite screed is quicker to install, faster to dry, and has greater thermal properties than cement.
Our Hydronics Design Engineers ensure that every project is a success, a large emphasis and importance is the design of our systems, we have experienced and certified Hydronic design Engineers as part of our team.
We use the best quality Materials European pipes, manifolds pump, boilers and heat pumps to ensure the best quality for your system.
A Team of Professional Engineers, Designers and Installers we have all the bases your project covered
WHAT IS AN ANHYDRITE SCREED
The anhydrite component is the chemical mineral calcium sulfate. When combined with water, it causes the formation of gypsum, which together when combined with sand forms the anhydrite screed. Gypsum screeds are not recommended in wet rooms such as bathrooms, laundry and balconies. It is also not suitable for outdoor areas. The screed is used above all when laying underfloor or surface heating.
Components and properties
Like conventional screed, anhydrite screed consists of three components calcium sulfate binder, Graded washed sand and Water. Once mixed the screed is pumpable and fully self levelling.
Screed thermal conductivity
If a the screed is to be laid over underfloor heating, it is simply pumped then poured over the heating pipes. The thermal conductivity of gypsum screed is between 20 and 30 percent higher than the conductivity of cement.
Due to the lower installation height of only 20mm above the heating pipes, the heat transfer is also accelerated. Most cement screeds are laid atThe shrinkage of anhydrite screed in also almost zero, so that the freshly applied screed dries faster when the heating systems are switched on.
For most projects heat and screed will applies anhydrite as a liquid screed. The mixed screed is poured onto the floor in a viscous form. It balances itself out due to the flow movement and levels itself.
Heat and Screeds strict processes make for the perfect end product.
