UNDERFLOOR HEATING
Lamineted Parquet and Underfloor Heating Systems
In addition, the use of multi-layer parquet instead of solid wood flooring protects the environment and natural resources. For example: from one cubic metre of oak wood only 35 square metres of solid wood parquet can be made, while using state-of-the-art production methods you can make around 115 square metres of laminated parquet.
Not all wooden parquet can be applied to underfloor heating
Compared to heating with conventional radiators, underfloor heating allows the room temperature to be lowered by about 3°C for the same warm air temperature! This significantly reduces energy consumption. In addition, the use of multi-layer parquet instead of solid wood flooring protects the environment and natural resources. For example: from one cubic metre of oak wood only 35 square metres of solid wood parquet can be made, while using state-of-the-art production methods you can make around 115 square metres of laminated parquet.
PRE-APPLICATION
Screeds must be applied in accordance with industry standards. All mineral structures must be heated before the installation of parquet, so that no harmful moisture remains. This heating process is required in all seasons. Cement screeds can be heated at least three weeks and anhydrite screeds one week after installation. One of the most important points to be considered is that there should be a thickness of at least 30 mm between the coils and the surface of the wooden screed layer. The screed under this thickness does not give a healthy result, with or without underfloor heating. After the protective screed dries, it is necessary to operate the underfloor heating system before proceeding to the application of parquet. The temperature should be increased daily in 5°C/9°F steps until the maximum heating target is reached. This procedure should be carried out during all heating periods. The time required to reach the maximum temperature with fully loaded operation depends on the type and thickness of the screed. For cement screed 1 day for screed thickness per cm For anhydrite screed 2 days for screed thickness per cm As a result of this, the screed will dry completely and cracks on the screed surface will be detected. If the superficial cracks on the screed have reached large dimensions and have become detached from the ground and cause movement, the necessary repairs must be made. The recommended method to minimize the surface cracks that may occur on the screed surface is to heat the water in the underfloor heating system around 35 degrees and reduce the screed moisture to the desired level in a controlled manner. After this process is over, the heating should be turned off and the screed should rest for 2-3 days. After the parquet laying process is finished, the system should be operated once again and the temperature should be increased by 3-5 degrees per day to bring it to the maximum temperature intended to be reached.
APPLICATION & USE
The relative humidity in the air should be 50-60%, the maximum humidity in the screed should be 25%, and the temperature should be at least 18 C. In underfloor heating systems, the heat that the hot water circulating in the coils can reach should theoretically not exceed a maximum of 50 degrees. This heat is transferred to the protective screed layer surrounding the coils at around 45 degrees. This heat in the screed is transferred to the base material walked on between 24 degrees and 30 degrees depending on the type of material and the ambient temperature to be reached. If the heat transferred to the parquet is more than 27 C, the risk of deformation of the parquet will begin and each degree of heat increase above 27 C will cause the risk to increase exponentially. The factory moisture values of the parquets are between 8-10%. This humidity rate remains stable in an environment with a temperature of 20-25 C and a relative humidity of 50-60%, and changes in these values in the plus or minus direction will cause the parquet humidity to change, thus causing the tree to move. When using the underfloor heating system, always start at low temperature at the beginning of the season and gradually increase the temperature to the maximum as specified before the application. Sudden increases should be prevented.
