There must be no areas of irregular shape.

The screed must be laid respecting the 126-4 joints where necessary. In relation to the screed, UNI EN recommends that its thickness is no less than that stipulated by the regulations specifying screed load capacity and bending strength class. Prove methods for the determination of the thermal output using calculation and test methods.

It is the part of the standard that regulates the installation of surface-embedded radiant systems. For at least 3 days the screed must be protected from drying too quickly.

It details the minimum material requirements to be used with a radiant 126-4 system and the requirements that have to be met for successful installation.

Tubing must be laid at least 50 mm from the perimeter and mm from any possible cause of damage to the tubing e. The two lengths of tubing of each circuit that cross the expansion joint both the feed and return tubes may cross only once must be protected with flexible insulation material for a length of at least 0.

Perimeter strips must also be left around all the structural components of the building that penetrate the screed e. Walls and ceilings must be able to support the radiant system. These dimensions may be exceeded in the case of rectangular areas if one dimension is no more than double the other.

It must be equipped with humidity sensors if operated in cooling mode to prevent reaching 12664-4 point temperature. It defines the conditions that must be present at the time of laying the radiant floor system: Let us help you with your project. If superficial cuts are made to the screed, these must not have a depth greater than a third of the thickness of the screed.

The thickness of the tubing must be such as to meet Class 4 requirements according to ISOresistant to a working pressure of 4 bar and expected lifetime of 50 years. For example, in the case of an external wall, one layer will be installed directly behind the radiant system and a second layer will be installed externally. The tubing used for the radiant floor circuits must have an oxygen barrier and meet the technical specifications of reference standards.

Tubing must be attached using a secure anchoring system that ensures the tubing does not move more than 5 mm vertically and more than 10 mm horizontally from the position where it was installed.
