Wherever you decide to use Gypsol screed you can be assured that our technical and specifications team are on hand to answer your technical queries and to assist with designs where possible.
This case study features a high energy efficiency home built to achieve Code Level 6 under the code for sustainable homes. It included features such as photo voltaic roof tiles, solar panels and a low temperature ground source heat pump.
The client required underfloor heating at both the ground floor and the first floor level which was to be supported with a standard concrete beam and block sub floor. The designer required a screed which could offer a rapid response to changes in the air temperature within the house both in terms of heating and cooling. Additionally it had to offer a thin section to reduce material use and to help reduce the physical mass of screed that had to be warmed. This in turn was to help with achieving efficiency with the ground source heat pump and allow the unit to heat the screed at very low temperatures. It also required a screed that could be easily placed at both ground and first floor and that would fully encapsulated the underfloor heating pipes to eliminate as many air pockets as possible. The screed depth on the both floors was designed at 75mm and they had originally intended to use a traditional sand cement screed.
Our technical and specifications manager was contacted and offered assistance with the designs and technical detailing in order to optimize the design using Gypsol Classic screed. Gypsol Classic was able to meet all of the requirements of the specification and offer numerous additional benefits besides.
Gyspol screeds can generally be laid thinner than traditional screeds and in this project the depth of screed at both floors was reduced to just 50mm offering the optimum thermal mass and response profile for the system. Gyspol screeds can achieve very high levels of energy efficiency at very low flow temperatures fitting perfectly with the ground source heat pump in this project.
We were able to suggest an increase in the depth of insulation due to the reduction of the screed depth, which meant the overall performance of the floor was enhanced. Gypsol screeds are made using raw material harvested as a bi-product of the chemical industry which require no high energy processing in order to make them suitable. This in turn reduces the carbon foot print of the screed considerably when compared to traditional sand and cement screed.
