Makrolon® multi UV 5M/40-20
Multiwall polycarbonate sheet
Your benefits:
• extremely heat-insulating
• high rigidity
• good load bearing capacity

Makrolon® multi UV 5M/40-20 is a polycarbonate sheet of
40 mm thickness, with a M-structure for enhanced stiffness.
It combines good load bearing properties, excellent thermal
insulation, light transmission and excellent weather resistance.
The sheet is lightweight, impact resistant and easy to install.
Makrolon® multi UV 5M/40-20 is ideal for flat glazing applications.
• conservatories
• industrial glazing, sports halls
• partition walls
• skylights, northlight glazing
• roofing, cladding (facades)
The sheets are produced with a coextruded UV-protective
layer, which is homogeneously fused with the sheet material.
This UV-protected side must be installed facing upwards/
outwards. It provides Makrolon® multi UV with a highly effective protection against weathering, guaranteed for 10 years.
On request:
IQ-Relax
Makrolon® multi IQ-Relax are opal white sheets, which
dramatically reduce the heat of the sunlight, allowing the
visible light to pass through. More light, less heat!

Bayer Sheet Europe i-line represents the next generation of quality products. This seal guarantees
innovative and intelligent first-class solutions at all times for a multitude of requirements.
If Makrolon® multi UV 5M/40-20 is used in applications of roofing (testing, monitoring and certification centre recognized by the building
or walling, the forces applied by wind and snow loads must be absorbed inspectorate). Adequate safety values, which should be assessed on
by a suitable sub-structure. We recommend taking the support distance a case-by-case basis, are to be observed with regard to these values.

In general, experience has shown that a safety factor of 1.3 is adequate
The diagram shows the load bearing capacity for Makrolon® multi UV with regard to the measured resistance values. This safety factor is
5M/40-20 (supported on all sides, rebate depth ≥ 20 mm). If the rebate included in the load table and the diagram.
depth is smaller, the support distances should be reduced suitably
for the given load. For pure wind loads the loads may be increased These statements do not replace the specified national certifiby a factor of 1.1.

Load bearing characteristics (determination):
The system resistance (boundary state of load bearing capacity)
of Makrolon® multi UV 5M/40-20 was determined in accordance
with European guideline ETAG 10 (European Technical Approval on
“self-supporting light-transmitting roofing systems”, which came
into force in September 2002) in real tests. The characteristic values
of system resistance were determined in an unfavorable system, i.e.
the sheets were not fixed, but laid loosely. The loads are applied as
uniformly distributed linear loads, i.e. load components acting vertically on the sheet, e.g. snow.
