Joints must be positioned – and be of sufficient number – to delimit areas don exceeding 40 m2 and no longer than 8 m. If superficial cuts are made to the screed, these must not have a depth greater than a third of the thickness of the screed.
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. For at least 3 days the screed must be protected from drying too quickly. Take the smart route to manage medical device compliance.

Extreme care must be taken when laying the screed so as not to damage any of the components of the radiant floor. These devices must also work in the absence of an electric current.
BS EN – Water based surface embedded heating and cooling systems. Installation
The distribution manifold must be positioned in such a way as to minimise the length of supply tubing required. 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.
Joints must be positioned by all the doors. In relation to the screed, UNI EN recommends that its thickness is no less than that stipulated by the regulations specifying screed load dim and bending strength class.
Circuit closure and circuit calibration must be independent. It defines the conditions that must be present idn the time of laying the radiant floor system: Click to enn more. It must be covered on top by a protective layer which can be a polyethylene sheet of thickness equal to at least 0. Search all products by.
Before laying the screed onto the coils, a pressure of no less than 4 bar and no greater than 6 bar must be applied to make sure there are no leaks.

It must be equipped with humidity sensors if operated in cooling mode to prevent reaching dew point temperature. The absence of leaks must be documented in a test report which must also include details of sn pressure at which the test was performed. Prove methods for the determination of the thermal output using calculation and test methods. Such protection may be necessary for a longer period if the type of material used for the screed so requires it.
The perimeter strip and protective insulation layer must be positioned in such a way that the screed does not seep along the perimeter under the insulation. Guide to radiant comfort Efficient design Radiant cooling Regulation Norms.
It is the part of the standard that regulates the installation of surface-embedded radiant systems. Determination of the thermal output BS EN The radiant floor must be laid leaving a perimeter strip along all the walls that delimit the area to be heated.
126-44 transport and storage on site, tubing must be protected from external damage and direct sunlight. These dimensions may be exceeded in the case of rectangular areas if one dimension is no more than double the other.
Walls and ceilings must be able to support the radiant system. 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.
The tubing used for the radiant floor circuits must have ddin oxygen barrier and meet the technical specifications of reference standards.
