Vysa-Film Far Infra-Red Radiant Floor Heating Elements 160W/m2
Vysa-Film ultra-thin Far Infra-Red Radiant Floor Heating Elements 160W/m2 are the ideal solution to provide an economic electric underfloor heating system for a variety of floor coverings. They require no maintenance and can provide significantly lower running costs than other heating systems.
Vysa-Film elements rated 160W/m<sup>2</sup> are suitable for less well-insulated applications, areas of high heat loss such as conservatories or, where less than 80~90% of the floor area can be covered with heating elements.
Vysa-Film can be installed as part of a refurbishment or new-build project. Installed on top of concrete or timber sub-floors or built into floors.
Vysa-Film is the perfect electric underfloor heating system for your home. Whether you choose fitted carpets, laminate, engineered wood, bamboo or, a specialist designer vinyl floor such as Amtico, Karndean or Rhino flooring.
Vysa-Film underfloor heating systems are perfect for installation under a high quality hardwood, wood laminate or wooden parquet floor.
Maintaining a relative humidity (RH) of between 30% and 60% in the dwelling will provide stability for a high quality wooden floor and ideal comfort for the occupants
Vysa-Film heating systems deliver greater personal comfort by controlling the radiation heat loss from the body. When the surrounding surfaces (warmed by radiant heat) are roughly the same temperature as our body, we feel comfortable with a good sense of well being.
Vysa-Film provides greater comfort than traditional central heating systems. It is a low temperature system which emits radiant heat energy (like that from the sun) to provide unrivalled comfort. Allergy suffers will benefit from the near absence of air circulation, dust and dryness associated with traditional systems.
The Vapour Barrier is required to provide additional supplementary insulation and is a requirement of the approval certificate to BS EN 60335-2-96.
Where the edges of the Vapour Barrier meet they should be overlapped by a minimum of 100mm (see diagram above) and covered with Vysa-Bond SAT strong adhesive tape.
Any of Vysal’s thermostats will control the floor temperature to a maximum of 28°C on a room by room basis, enabling significant energy savings to be achieved yet providing optimal comfort with lower air temperatures than with traditional systems.
For the technically minded – not all carbon film is the same. The technology of producing a semi-conductive carbon film that will emit radiant energy has been available for about 30 years. It is made in the US, China and Korea as well as the UK. Vysa-Film radiant heating elements are superior to the run-of-the-mill products using basic carbon film produced by our competitors and are made only in the UK..
The semi-conductive carbon and other materials used in the manufacture of Vysa-Film have been developed specifically to Vysal’s exacting requirements emit radiant heat energy within the far infrared part of the electromagnetic spectrum at wavelengths of 5 ~ 20 microns. Instead of heating air, radiant energy warms people and objects directly and extremely efficiently.
Vysa-Film is manufactured uniquely for Vysal to comply with the BSEN 60 335-2-96 within a UK based factory with a quality system independently certified to ISO 9001, ensuring that it meets the requirements of the 17th Edition Wiring Regulations (BS7671:2008).
Vysa-Film is only a fraction of a millimetre thick. It comprises a thin layer of a special semi-conductive material printed onto a base layer of polyester film. Copper electrodes, connecting the mains supply across the semi-conductive layer, causing current flow, extend the full length of the element. A second layer of polyester film is laminated over the base layer to hermetically encapsulate everything. Electrical connection leads are provided at one end of the element.
Because we manufacture the finished Vysa-Film heating elements in our factory ready for installation by others, we can tailor their length and connection leads to customer requirements and yet still offer delivery within 24 hours.
Thermal blocking occurs when the heat produced by the radiant floor heating system is trapped and has no way of escaping from the surface of the floor.
This can cause the heating system to overheat in the thermally blocked area and, in extreme cases, affect the integrity of the floor covering and heating system. Thermal blocking can be caused by placing items that act as efficient insulators onto the heated floor surface and do not allow heat through.
For example, many rubber-backed rugs, shag pile rugs, bean bags, pet beds and movable furniture that stands flat to the floor or permanent furniture or features such as shower trays can cause thermal blocking.
Furniture should have an air gap of at least 100mm between the heated floor and the underside of the furniture to avoid thermal blocking. The air gap should be ventilated and not closed off so that convection currents can distribute the heat emitted from the floor.
Heated floors are sometimes used to dry washing or other wet items such as towels, pet blankets, coats and rugs.
Thermal blocking is not usually a problem with ceramic tiled floors as they will normally dissipate the heat from the radiant heating system around any thermal block. However, Vysa-Film heating elements are much more susceptible to thermal blocking and much greater care should be taken to ensure that your heating system is not damaged by customer abuse.
The system will usually tolerate small amounts of abuse but you should take care not to mis-use your new radiant floor heating system too badly or it will fail and is not covered under the guarantee in such circumstances.
Installation – Before laying Vysa-Film on either a suspended wooden floor or concrete sub-floor, it is necessary to install Vysa-Pron 6mm thick insulation. This will minimise heat loss (and save electricity) and ensure quicker heat-up times. It also improves sound-deadening, especially useful with laminate floors. Finally, it provides a smooth surface for the Vysa-Film without projections that might damage the heating elements.
Next, roll out the pre-cut lengths of Vysa-Film ensuring that the cold tails are located at the end where the thermostat will be installed. Make sure that none of the heating elements overlap. Cover the whole floor (including unheated areas) with a layer of Polyester Vapour Barrier and secure it in place before laying the chosen floor covering.
Vysa-Film also has many commercial applications and we have supplied customers for showrooms, commercial kitchens, temples, sports halls etc. Below is a system being installed at a nursery school.

Cut a channel in the sub-floor to accommodate the black flexible tube that will house the floor probe. This should be deep enough to ensure that the top of the conduit is level with the top surface of the Vysa-Pron insulation board when laid. The conduit should be positioned centrally below one of the heating elements at a distance of approximately 500mm from the wall. Place the remote floor sensor in the conduit, tape over the end and run the cable back to the junction box.
Thoroughly clean the sub-floor and remove any sharp objects. Lay the Vysa-Pron thermal insulation sheet flat on the floor, staggering the joints in a “brickwork” fashion. Tape the edges. Carefully cut a channel in the insulation to accommodate the sensor conduit and tape in place.
Roll out the lengths of Vysa-Film copper side down, taking care to locate the “cold-tails” on the wall nearest the thermostat connection box. Ensure the cables are not placed under the heating elements.
Cut a channel in the insulation along the connection lead/thermostat wall side to accommodate the connection leads. Run the leads in the channel to the junction box and tape in position.
The Vysa-Film elements must now be covered with a layer of Polyester Vapour barrier to provide optimum moisture and additional mechanical protection. Rolls of Polyester Vapour barrier should be overlapped by 100mm and taped over the entire length of the overlap using Vysa-Bond SAT Tape. One roll of Polyester Vapour barrier will cover approximately 20m² of floor. Always cover the entire floor with vapour barrier, even unheated areas before laying the chosen final floor covering. Lay the floor covering as soon as possible to prevent damage to the element.
A fully qualified Electrician must now make the final connections to the mains.
Q. Can I use Vysa-Film under real timber floors?
A. Yes, Vysa-Film can be laid under laminates, Engineered Board and solid timber floors.
Q. Do I have to use Vysa-Pron thermal insulation board under Vysa-Film?
A. Yes. Vysa-Pron provides several qualities to the installation. It effectively levels small imperfections in the floor, is an excellent thermal insulation barrier, replaces the underlay required by laminates and provides excellent sound insulation qualities.
Q. Why do I have to cover the Vysa-Film with Polyester vapour barrier before laying my finished floor covering?
A. The Polyester vapour barrier acts as an additional layer of the electrical insulation, provides mechanical protection and acts as a moisture barrier between the sub-floor and the finished floor. It MUST be installed.
Q. Can Vysa-Film be laid over any type of subfloor or are there limitations?
A. Vysa-Film can be laid over most floor types (Concrete, Wood etc) using Vysa-Pron as the underlay. It should not be laid in conjunction with a metallicised underlay system.
Q. What heat output does Vysa-Film have?
A. Our standard Vysa-Film is rated at 130 watts/m² and 160 watts/m² depending on the heat loss of the installation.
Q. Can I use Vysa-Film to heat my bathroom floor?
Q. What is the minimum floor level build up height I will have when I use Vysa-Film under my laminate floor?
A. Vysa-Film is an ultra thin flexible heating element (only 0.2mm thick). The total floor level build using the system which includes Vysa-Pron 6mm insulation and vapour barrier is less than 7mm.
Q. Is installing Vysa-Film a task best undertaken by a specialist installer?
A. Vysa-Film can be installed by any competent person. It involves a simple dry installation method using no special tools or skills. Installation instructions are comprehensive, clear and concise. Vysa-Film is supplied with pre-wired electrical connections so no electrical work is required before laying the final floor covering. Final electrical connection to the mains supply must be carried out by a suitably qualified electrician.
Q. Why should I choose Vysa-Film in preference to Vysal heating cables or mats?
A. It depends on the final floor covering and the application. For heating floating wooden floors Vysa-Film is the easiest and most economic system. For heating tiled floors in bathrooms we would recommend Vysal heating mats or cables.
Q. Can I use Vysa-Film under carpets or vinyl flooring?
A. Yes you can if the correct “overboarding” installation procedure if followed. Please refer details on our Vysa-Floor Free Floating Sub-Floor which must be fitted over the Vysa-Film before laying the carpet or vinyl.
