Heating film under the screed and tiles

Underfloor heating with Heat Decor heating film under the screed is mainly used in newly designed residential and office buildings, industrial halls or facilities for major renovation. Underfloor heating under the screed is dedicated to continuous operation as the basic heating system for space heating.

Heating film in newly designed houses and apartments

In houses and apartments, the heating film under the screed is installed in every room, starting from the living room, kitchen, rooms, corridors and bathrooms. Heating film in combination with an anhydrite or cement screed form a storage heater system. When the screed heats up, heat is distributed evenly over the entire surface of the floor, giving the effect of a uniform heating plate. The accumulated heat is released into the room inertly over a long period of time. The heating film maintains a stable temperature of the floor, ensuring comfort of use. Underfloor heating with a heating film under the screed, unlike typical water underfloor heating systems, is characterized by the fact that the change of temperature in the room and floor temperature takes place in a shorter time, because the heating film has a large heating surface and I have no losses in energy transmission compared to traditional heating systems.

The heating film is placed directly under the ingot, which makes the room temperature control and the temperature of the floor itself very precise. Stable temperature in the heated room in the surface heating system with heating film is maintained by an electronic thermostat measuring the air temperature in the room and the floor temperature, creating a complete maintenance-free heating system.

Heating film under the screed and types of floors

Underfloor heating with heating film under the screed gives a wide range of installation options for various types of floor coverings. Thanks to the stable base, we can use floor finishing materials glued to the screed or in a floating form . In the heating system under the screed, we can use ceramic tiles, stone cladding, glued wood, floating layered floors, laminated panels, vinyl panels, carpet flooring, PVC floor coverings, resin floors and other materials suitable for underfloor heating.

  1. Fugue

Material for pointing ceramic and stone tiles. The joint must be flexible and resistant to thermal deformation. The grout should be resistant to moisture, fungi and mold. Grouts of CG2 class, containing polymer modifiers, are used for underfloor heating.

  1. Ceramic, porcelain and stone tiles

The floor covering fulfilling functional and decorative functions with appropriate anti-slip parameters and resistance to abrasion.

  1. Flexible adhesive

Material for gluing floor coverings, fulfilling binding, strength and elastic functions. The type of flexible adhesive is selected according to the floor covering. Adhesives in class C2S1 are used for underfloor heating.

  1. Priming layer

The priming layer is an emulsion-coated priming surface used to level the absorbency of the screed and increase the adhesion of floor coverings glued to the screed.

  1. Anhydrite or cement screed

Underlay material designed to even out the subfloor before laying the floor covering. The thickness of the screed is adjusted to the designed loads as well as the type and thickness of the insulation on which the screed is made. The recommended minimum thickness of the screed in residential construction is 5 cm. The method of making dilatation of the screed and its seasoning should comply with the recommendations of the screed manufacturer.

  1. Vapor barrier foil thickness min. 0.3 mm

The LDPE vapor barrier foil with a minimum thickness of 0.3 mm is the basic coating that protects the entire underfloor heating system against the effects of moisture and water. The vapor barrier foil must provide a uniform surface over the entire floor. The vapor barrier foil must be resistant to mechanical damage and have a very good water barrier, because anhydrite or cement screed is poured over the layer of this vapor barrier foil.

  1. Heat Decor stainless steel mesh

Heat Decor stainless steel mesh, 0.12 mm thick, serves as grounding of the electrical installation with a heating foil. The stainless steel mesh is grounded with an electric wire connected to the mesh with an installation connector. We recommend grounding the underfloor heating system with the heating foil to increase the safety of use of the entire heating system. An earthed underfloor heating system must have a residual current device in its circuit, which guarantees the safety of the heating system.

  1. Vapor barrier foil thickness min. 0.2 mm

LDPE vapor barrier foil with a minimum thickness of 0.2 mm protects the heating film against mechanical damage to the heating film resulting from the friction process during shrinkage and expansion of the Heat Decor stainless steel mesh.

  1. Heat Decor heating film

The Heat Decor infrared heating film is the main heat carrier in underfloor heating. The heating film is connected to the electric wires with installation connectors and then connected to the room thermostat equipped with a built-in air temperature sensor and an external floor temperature sensor. The heating film must be grounded and have a residual current device in its circuit to ensure the safety of the heating installation.

  1. Vapor barrier foil thickness min. 0.2mm

The vapor barrier foil, minimum 0.2 mm thick, protects the heating system against the effects of moisture. The even vapor barrier surface protects the heating film against the possible process of moisture arising from the capillary substrates as a result of improperly performed insulation of the foundation, walls or screed, as well as the result of forest incidents such as flooding with water.

  1. Expansion tape – edge

The expansion tape is used to circumferentially separate the screed layer from the wall in order to protect the screed against cracking and lifting caused by shrinkage and expansion of the screed due to changes in temperature and humidity of the screed. Expansion profiles are also used for the dilatation of the screeds. Use the thickness of the expansion joints and the use of expansion profiles in accordance with the recommendations of the screed manufacturer.

  1. Thermal insulation made of expanded polystyrene

The floor polystyrene serves as thermal insulation and should have the appropriate hardness adapted to the designed screed and subsequent floor coverings. Thermal insulation made of foamed polystyrene is a very important element of the operation of the entire heating system. The quality of thermal insulation directly affects the selection of the power of the heating system and subsequent operating costs. The selection of the type of polystyrene, thickness and its compressive strength is made by the designer of the construction industry.

  1. Concrete screed

Concrete screed, reinforced concrete ceiling or foundation slab are elements of the load-bearing structure of the building with waterproofing made, constituting the basis for the underfloor heating system.

A suitable substrate for the construction of a floor heating system can also be a wooden structure or a structure made of OSB and MFP boards meeting the standards of load-bearing capacity and building structures.
