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:
- Follow the MULTIBETON plan for installation.
- Refer to the MULTIBETON installation and technical guidelines for further instructions.
- Ensure compliance with relevant laws, regulations, directives, and standards when planning and creating the MULTIBETON underfloor heating/cooling system.
- 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
The FLS-35/27 is a heating and cooling system for general resi-dential and office buildings, particularly for renovating and remodelling existing buildings for high loads with a minimal installation height and weight and fast control.

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:
- Sound insulation,
- Compensating expansion in the heated load distribution layer,
- 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.
