The standard describes the installation of the radiant surface, distinguishing between radiant floors, walls and ceilings. It must be covered on top by a protective layer which can be a polyethylene sheet of thickness equal to at least 0. These dimensions may be exceeded in the case of rectangular areas if one dimension sin no more than double the other.
The radiant floor must be laid leaving a perimeter strip along all the walls that delimit the area to be heated. I want to be contacted. Before laying the screed onto the coils, a pressure of no less than 4 bar and no greater than 6 bar must be applied 2164-4 make sure there are no leaks. You may find similar items within these categories by selecting from the choices below:. The tubing used for the radiant floor circuits must have an oxygen barrier and meet the technical specifications of reference standards.
The thickness of the tubing must be such as to meet Dij 4 requirements according to ISOresistant to a working pressure of 4 bar and expected lifetime of 50 years.
The screed must be laid respecting the expansion joints where necessary. For at least 3 days the screed must be protected from drying too quickly. The absence of leaks must be documented in a test report which must also include details of the 11264-4 at which the test was performed.
Circuit closure and circuit calibration must be independent. Search all products by. The distribution manifold must be positioned in such a way as to minimise the length of supply tubing required. 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.
BS EN – Water based surface embedded heating and cooling systems. Installation
During transport and storage on site, tubing must be protected from external damage and direct sunlight. It is the part of the standard that regulates the installation of surface-embedded radiant systems. There must be no areas of irregular shape. The flooring contractor must check that the chosen floor finish is compatible with the conditions.
BS EN 1264-4:2009
Joints must be positioned by all the doors. Walls and ceilings must be able to support the radiant system. If superficial cuts are made to the screed, these must not have a depth greater than a third of the thickness of the screed.
It defines the conditions that must be present at the time of laying the radiant floor system: Tubing must be laid at least 50 mm from the perimeter and mm from any possible cause of damage to the tubing e.
This is to avoid excessive supply tubing making it difficult to manage the temperature of the different rooms. 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.

Customers who bought this product also bought BS EN The perimeter strip must penetrate down to the very bottom of the support and continue up to the finished floor level, allowing for at least 5 mm of screed movement.
All the service tubing to the systems hydraulic, electrical, sanitary, etc. Subscribe to the newsletter. 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.
Prove methods for the determination of the thermal output using calculation and test methods. 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.
It details the minimum material requirements to be used with a radiant surface system and the requirements that have to be met for successful installation. Perimeter strips must also be left around all the structural components of the building that penetrate the screed e.
