STYROPIAN FOR FLOOR HEATING KNAUF Therm EXPERT FLOOR HEATING EPS 200 λ 33 gr.2cm

Product description

KNAUF Therm EXPERT FLOOR HEATING EPS 200 λ 33 is a board for thermal insulation of the floor in a water floor heating system. Thanks to its construction, the installation of heating cables is very simple and very fast. The plate is made of dense expanded polystyrene, which protects it from moisture absorption. Due to its universality, it can be used in residential and public buildings.

Advantages of the KNAUF KNAUF Therm EXPERT FLOOR HEATING 200 λ 33 product:

• The tab system allows quick and easy installation of heating pipes. 
• The shape of the tabs guarantees the stability of the pipes without the need for additional materials blocking the pipes.
• Innovative edge profiling allows for tight and durable joining of panels. 
• The back side of the plate in the form of a "chessboard" enables precise cutting of the plate 
• High thermal resistance

KNAUF Therm EXPERT FLOOR HEATING 200 λ 33 PANEL FIXING GUIDELINES
Floor heating
It is a low-temperature space heating system operating on the principle of surface heat radiation where 70% of heat energy is transmitted by radiation and 30% by convection. Underfloor heating provides a sense of thermal comfort, thanks to the even distribution of heat throughout the entire surface of the room and the favorable temperature distribution in the room.

The advantages of underfloor heating are:

• the possibility of freely shaping the space of the heated room (no traditional heaters) 
• increased thermal comfort due to reduced convection movements, increased air purity 
• the possibility of reducing seasonal heat consumption compared to central radiator heating 
• self-regulating property, consisting in the automatic change of the thermal power of the ducts as a result of a change in the internal temperature in the room.

Underfloor heating operation parameters
According to the requirements of DIN 4725, floor heating has a limited surface temperature. The optimum temperature is 24 - 26 C. Due to the feeling of thermal comfort, the floor temperature should not exceed:
24 C - in the area of permanent residence of residents (living and office rooms)
35 C - in the coastal area (at the outer walls of the building)
33 C - in bathrooms
27 C - in work rooms where you work standing up
Other output parameters for floor heating design should be:
55 C - permissible flow temperature
55 C - temperature difference between supply
0.1 - 0.6 m / s - water flow speed in the heating pipes
90% - efficiency of heat energy transfer through the heating system to the room

What is KNAUF Therm EXPERT FLOOR HEATING 200 λ 31?

When considering an underfloor heating system, large heat losses should be taken into account. This is the case with all types of installations. First of all, it is necessary to analyze very carefully and precisely what kind of materials to use so that the heat loss is as low as possible.

The best solution is therefore a foam board FLOOR HEATING 200 λ 31, which guarantees a very good heat factor of λD - 0.031 [W / m • K]. It turns out that even compared to foamed polystyrene boards with metallized foil, it is much more advantageous. For this purpose, polystyrene boards with metallized foil were analyzed by several manufacturers, averaging their declared heat conductivity coefficient, which is at the level of 0.035 [W / m • K]. The calculations have confirmed the excellent quality and effectiveness of FLOOR HEATING 200 λ 31 polystyrene boards, which, as you know, will result in significantly lower heat losses in the building.

Comparison of material prices - additional advantages

FLOOR HEATING 200 λ 31 boards also look much better when it comes to lower costs associated with the use of insulation material. This translates directly into shorter assembly time (4 minutes shorter per one square meter, or 20%), and lower labor costs. Not only are the additional materials necessary for the installation of the FLOOR HEATING 200 λ 31 board cheaper, but also the current meter of polystyrene is up to 20% cheaper, compared to a polystyrene board with metallized foil. Assembly solution The FLOOR HEATING 200 λ 31 boards are based on another system, namely they take the form of locks to ensure precision. Importantly, with this type of assembly there is no problem of acoustic and thermal bridges.

It should also be emphasized that in the case of FLOOR HEATING 200 λ 31, the consumption of screed per square meter is up to 25 percent lower compared to screed on foamed polystyrene. This is due to the protrusions on the upper surface of the Knauf board, which reduce the need for such material exploitation. As a result, screed consumes up to 45% less time.
