>This standard defines the gtot solar factor (fabric + glazing) as
being the most outstanding thermal property. Internal blinds will give
superior results with the light or reflective side of the fabric towards
the exterior.
Equivalence of thermal comfort (gtot) according to the EN 14501
classification and the threshold values set by the RT 2012.

specifying the geographical situation, building’s orientation, glazed
surface of the room, blind position and colour of the fabric.

4 comfort factors to choose the right fabric for the function and
colour required and ensure the success of your solar protection.
Level of incoming natural light:
For the same type of fabric, light colours let through more light than dark
colours.
Glare control:
For the same type of fabric, dark colours provide better glare control than
light.

Protection against the heat gain from sunlight:
External applications provide a more effective heat protection. For a better
protection, dark colours should be used externally and light colours
internally.
Quality of outward visibility:
The quality of the outside view is not only created by the fabric openness factor
but also its light transmission which varies with colours. Darker colours will
provide better outward visibility.

The main thermal and optical factors
The regulations value the gtot factor for thermal comfort and Tv for visual comfort.
>Thermal factors
Ts Solar transmittance: proportion of solar
energy transmitted through the fabric. A low
percentage means the fabric performs well at
reducing solar energy.
Rs Solar reflectance: proportion of solar radiation
reflected by the fabric. A high percentage means
the fabric performs well at reflecting solar
energy.
>Optical factors
OF Openness Factor: relative area of the openings
in the fabric (hole). It is considered as independent
of the colour. For fabrics with the same weave, it
should be measured using the darkest colour in
the range.
As Solar absorptance: proportion of solar radiation
absorbed by the fabric. A low percentage means the
fabric absorbs little solar energy.
Solar radiation is always partially transmitted
through, absorbed or reflected by the fabric. The
sum of all 3 equals 100.
Ts + Rs + As = 100% of solar energy.
gtot Total solar factor: solar energy which
actually penetrates into a room through the blind
and glazing. A low value means good thermal
performance.
Tv Visible light transmittance: total percentage
of light radiated through the fabric over a
wavelength of 380 to 780 nm (nanometers), called
the visible spectrum (total illumination).
Intelligent fabrics

Optical factors (cont’d)
Rv Visible light reflectance: proportion of light reflected by
the fabric.
Tdif Diffuse transmission factor: correlation of the two
factors above: Tdif = Tv – OF.
It is indicated as Tvndif for the aspects of glare and shape
recognition (outward visibility / night privacy). A low figure
shows a better visual comfort.
However, for natural light control, it is indicated as Tvdifh. It
is used to ascertain a fabric’s light diffusion capacity. A high
figure means more natural light.

Samples tested according to EN 14500 standard defining the measurements and calculation methods as specified in the standard EN 13363-1 "Solar protection devices
combined with glazing calculation of solar and light transmittance – Part 1: simplified method" and EN 410 "Glass in building – Determination of luminous and solar characteristics
of glazing".

Advice M-Screen 8503
> Storage conditions
The rolls of fabric should be stored horizontally, but not
piled up, in a place where the temperature and level of
humidity is as constant as possible.
The fabric should never be folded. For long-term storage, it
is not advisable to leave rolled or folded panels on top of
each other.
> Advice for blind making
The panels of fabric are cut by blade or ultrasonically.
They can be welded (thermal, high frequency or ultrasonic)
or sewn together.
The fabric must be properly squared before it is made up,
especially for large blinds or structures.
It is recommended to add a strengthening strip made of
translucent coated fibreglass to weld seams and
pockets. Horizontal seams give the best result.
For tensile structures, it is better to strengthen the
panel’s angles and make a pocket to fit all the way round
the panel, notably to support eyelets.
Very long blinds may need the addition of stiffeners to
ensure they will still hang properly after time.
> Marking
Mermet ® fabrics are suitable supports for digital printing,
screen-printing, paint and adhesive.

> Care instructions
Remove dust with vacuum
cleaner or compressed air.
Do not scrub.
Do not use solvents or any
abrasive substance that might
damage the coating of fabric.
Clean with a sponge or soft
brush dipped in soapy water.
Rinse with clear water.
Leave the blind down until
completely dry.
