MULTIBETON FLS-35-27 MB Flat System Instruction Manual

MULTIBETON FLS-35-27 MB Flat System

Product Information

The MB Flat System FLS-35/27 is a heating and cooling system designed for general residential and office buildings. It is particularly suitable for renovating and remodeling existing buildings with high loads, thanks to its minimal installation height and weight, as well as fast control.

Construction height:

• 27 mm for the FLS-27 model
• 35 mm for the FLS-35 model

Pipe covering:

• 7 mm for the FLS-27 model
• 15 mm for the FLS-35 model

Construction mass: (specific information not provided)

Traffic load: (specific information not provided)

Flooring: Suitable for all types, including cross joint (tiles up to 600 x 600 mm).

MULTIBETON GmbH develops and produces energy-efficient heating and cooling systems for various applications. The MB Euro system pipe (MB-ER17) is installed warm, ensuring it remains strain-free and twist-free when placed in the MB Steel clip rail (MB-CS17).

Product Usage Instructions

System Installation:

1. Follow the MULTIBETON plan for installation.
2. Refer to the MULTIBETON installation and technical guidelines for further instructions.
3. Ensure compliance with relevant laws, regulations, directives, and standards when planning and creating the MULTIBETON underfloor heating/cooling system.
4. Observe additional instructions from manufacturers of other trades and adhere to recognized rules of technology and proper trade workmanship.

Packaging Units:

• MB Lightweight screed (MB-LES)
• MB Glass fibre mat (MB-GFM)
• MB Thin screed (MB-DES & MB-DEP)

Consumption Data:

For 27 mm construction height:

• MB Lightweight screed (MB-LES)
• MB Glass fibre mat (MB-GFM)
• MB Thin screed (MB-DES & MB-DEP)

For 35 mm construction height:

• MB Lightweight screed (MB-LES)
• MB Glass fibre mat (MB-GFM)
• MB Thin screed (MB-DES & MB-DEP)

State of Construction:
Prior to installing MULTIBETON underfloor heating, make sure that windows and exterior doors have been installed. Building service installations and wall plaster should also be completed, and pipe slits must be sealed. Ensure there are no draughts on site.

Joints:
Floating screed naturally expands and contracts. To prevent damage, joints must be placed to accommodate this expansion and contraction. A joint plan indicating the type and location of joints should be prepared by the building planner and submitted to the installer as part of the technical specifications.

Construction Waterproofing:
If the building parts are in contact with the ground, they must be sealed in compliance with the standards. This applies to floors on the ground floor in buildings without a basement or basement floors. The need for waterproofing and the appropriate form should be determined by the structural design. The seal must be installed before the underfloor heating system is installed.

Applications

General floor construction
MULTIBETON develops and produces energy-efficient heating and cooling systems for a vast variety of applications. Planning the floor construction must comply with the relevant laws, regulations, directives and standards. The MB Euro system pipe
(MB-ER17) is installed warm and therefore stainless and twist-free in the MB Steel clip rail (MB-CS17).

System installation
Installation follows the MULTIBETON plan. Then follow the MUL-TIBETON installation and technical guidelines. Planning and creating the MULTIBETON underfloor heating/cooling must further comply with the relevant laws, regulations, directives and standards. Additional instructions of manufacturers for other trades and the recognized rules of technology and proper trade workmanship must be observed.

Thermal and impact sound insulation/film
Insulation with a compression strength of at least 150 kPa may be used with the FLS-35/27. In addition, sound insulation requirements must be met. XPS insulation should not be used for noise protection reasons. The insulation must be walkable and must not lose its properties when installing the system. If a construction project requires additional sound insulation, this must be expressly requested by the builder beforehand. MB-

PEF
(Polyethylene foil) must be used over the thermal and impact sound insulation. It protects the insulation against moisture and water vapour.

Edge insulation strip
Edge insulation strips have the following important functions, among others:

1. Sound insulation,
2. Compensating expansion in the heated load distribution layer,
3. Insulation between cold building parts and the heated screed. Under the standard, the edge insulation strip must be secured to prevent shifting when the screed is laid. The edge insulation strip must have at least 5 mm to expand. The edge insulation strip is placed on the finished floor or, in the case of two-ply insulation, over the bottom insulation layer. Once the flooring has been laid, the protruding edge insulation strips are cut.

State of construction
Windows and exterior doors should be installed before MULTIBE-TON underfloor heating is installed. Building service installations and wall plaster have been completed and pipe slits sealed. Ensure there are no draughts on site.

Joints
Floating screed expands and contracts by nature. Joints must be placed to allow for this expansion and contraction without damaging the screed. A joint plan showing the type and location of joints must be drawn. The joint plan is drawn by the building planner and must be submitted to the installer as part of the technical specifications.

Load-bearing surface
The load-bearing floor must be sufficiently dry to hold the load distribution layer and be even. The flatness tolerances according to DIN 18202 Table 3 Line 4 must be observed. The substrate must not have bumps, pipes or similar or these will show in the finished floor. On principle, the load-bearing capacity and insulating properties of the existing subfloor must be suitable. In the case of flexible surfaces, movement, sound transmission and noise generation must be expected. Carry out preliminary tests if unsure.

Construction waterproofing
Building parts in contact with the ground must be sealed in compliance with the standards. These are floors on the ground floor in buildings without basement, or basement floors. The need and form is determined by the structural design. This seal must be installed before the underfloor heating is installed.

Levelling courses
If the required flatness tolerances of the load-bearing floor are not met, it must be levelled with a levelling course. This requirement applies to all load-bearing floors in existing buildings and new constructions. The type of levelling course must be compa-tible with the planned underfloor heating system and room use.

Flooring
Since underfloor heating is quite common, the builder has vast flooring options to choose from. Almost all manufacturers offer flooring suitable for underfloor heating. Flooring such as textile flooring, natural stone, elastic flooring, ceramic flooring, par-quet, laminate and even wooden flooring can be used. The finis-hed floor must be installed according to the general installation rules for flooring installers. A trowel polish is required prior to installation. Tiles must be installed over a uncoupling membrane. The installed area must be treated with standard acrylate primer after 3 days.

Silent cooling
MULTIBETON underfloor heating is ideal as “Silent cooling”. These systems are inexpensive, as they only require a cooling unit or a reversible heat pump with the corresponding control unit. The maximum output (30 – 50 W/m²) of “Silent cooling“ comes from the dew point calculation, the calculated lowest cooling flow temperature and the user’s comfort level.
The design of the cooling components, including the insulation of the heating circuit manifolds, must be carried out in proper trade workmanship.
