The bioclimatic roller shutter slat has been designed to meet the challenges of the RE2020. It has been developed to offer a real solution to solar radiation and ensure optimum comfort in the home in both summer and winter.
Thanks to its regular micro-punching, the bioclimatic blade controls solar gain and offers 4 times more light and ventilation in living areas than a standard blade. It therefore guarantees real comfort in summer, while maintaining exceptional visibility to the outside when open, with an excellent light transmission factor.
In ALU, it provides security and total opacity in the closed position for optimum sleeping comfort thanks to the development of our rubber seals integrated into our guides. It also offers improved acoustic comfort when the curtain is raised and lowered. Multifunctional, it can be used with an integrated insect screen and blinds. Ideal for large bay widths, it is the only roller shutter slat on the market to have these types of features.
Thanks to its features, the bioclimatic slat greatly reduces heat transmission through the window. This limits the rise in temperature inside the home, reducing the need for air conditioning.
Performances :
SOLAR PROTECTION
Actual performance depends on your specific configuration. Our technical department can provide a gtot calculation on request, based on your chosen colour and glazing specification.
The Lame Bioclimatique® has established itself as
one of the most effective solar protection solutions on
the market (Class 4 according to NF EN standards and
CSTB test reports).
It blocks up to 98 % of solar heat (with standard glazing),
significantly outperforming a conventional roller blind
(Class 3) or an external venetian blind (Class 2).
| Lame Bioclimatique® light Colours with standard glazing | The gtot solar factor | % of heat trapped |
| Closed position | 0,02 | 98% |
| Ventilated Position | 0,0 | 95% |
The gtot solar factor measures the amount of solar energy transmitted through the solar protection system and the glazing. It is expressed as a value between 0 and 1: the closer
the value is to 0, the more effective the thermal protection.
NATURAL VENTILATION
The Lame Bioclimatique® provides enhanced natural ventilation, delivering
an airflow of Qa = 939 m³/h per m² of apron (CSTB test report).
NATURAL LIGHT
Normal/hemispheric light transmission factor :
Tvnh = 3% (PV CSTB)
When in the ventilated position, the Lame Bioclimatique® louvre provides excellent glare
control. It therefore offers optimal light levels whilst ensuring better sun protection.
PROTECTION AGAINST THE COLD
It limits thermal transfer and helps maintain indoor comfort during colder
Rsh = 0,01 m².K/W
Classe 4 : ΔR = 0,15 m².K/W
Classe 5 : ΔR = 0,18 m².K/W
RÉSISTANT AU VENT
The Lame Bioclimatique® offers
excellent rexcellent resistance to wind and harsh weather conditions. Sturdy and durable, it guarantees optimum safety in everyday use.
RÉSISTANT À LA CORROSION
New aluminium strip with enhanced corrosion resistance. Salt spray tested (CSTB test report).
Complementary products
We recently invested in an aluminium roller shutter slat profiling machine. This is located in our new 5,000 m² extension, part of which is dedicated exclusively to this new profiling ‘business’ at Geplast. This integration will enable us to acquire new technical skills and gain complete control over the production of our Bioclimatic® slat. This investment is part of a ‘responsible’ approach to meeting the challenges of the RE2020, which now requires controlled ventilation and solar gain in homes.
