The construction of new buildings offers enormous potential to reduce
harmful emissions and conserve resources. In all kinds of buildings, energy from
fossil raw materials is needed for both cooling and heating purposes, and it is
the carbon dioxide emissions resulting from this that are partly responsible for
greenhouse gases.
With insulating panels made of Makrolon® - the proven polycarbonate from Bayer MaterialScience - the
energy efficiency of buildings can be increased and the level of emissions
reduced.
Bayer MaterialScience now markets a wide range of heat-insulating panels for
roof and façade glazing under the name i-LINE. The methods used for their
production also conserve resources, as the Life Cycle Assessments
(LCA)
for them clearly prove. The constituents in the semi-finished products are
equally safe, being halogen-free in line with DIN/VDE 0472 Part 815, free of
heavy metals according to the US CONEG guidelines, and free of ozone-depleting
substances (ODS). Because the polycarbonate is not self-igniting, the sheets do
not harbor any risk of fire propagation or of burning parts falling down. They
thus comply with the international specifications for the fire behavior of
building products. In the event of a fire, no additional toxic substances are
released, and the smoke density is low. A further bonus with Makrolon® sheets is
that fire tests carried out under real-world conditions have shown that the
molten areas of the sheet act like an extractor - gas, smoke and heat are drawn
off upward and the substructure enjoys maximum protection.
The i-LINE from Bayer MaterialScience is highly diversified. The product
range offers a wide choice of highly heat-insulating sheets for environmentally
friendly building:
Makrolon® multi UV is a range of highly heat-insulating multi-wall sheets
with special UV protection (Australian Standard AS/NZS 4399:1996). The new
Makrolon® multi UV 5M has an M structure resulting in outstanding insulation
properties. Depending on the thickness of the sheet, the heat transfer
coefficient Ug is between 1.0 W/m2K and 1.3 W/m2K.
Makrolon® multi
IQ-Relax drastically reduces heat and provides a pleasant, cozy room climate all
year round. The product also boasts high transparency and low
reflectance.
Makrolon® multi CS UV is a clear, transparent, UV-resistant,
multi-wall corrugated sheet with a low heat transfer
coefficient.
Makrolon® UV ClimateControl, a transparent polycarbonate
sheet, has a UV-protective coating on both sides. It largely blocks out infrared
light and thus ensures a pleasant room climate over a wide temperature
range.
Makrolon® Ambient is a transparent multi-wall sheet filled with
Nanogel®.
The heat transfer coefficient Ug is only 0.99 W/m2K when
installed either horizontally or vertically, much higher than that of all known
conventional glazing.
The full range of products for the building
industry includes solid (GP), multi-wall, and corrugated (CS) polycarbonate
sheet. It is available in many color variants as well as transparent,
translucent and opaque. The tough, resilient sheets are available in numerous
sizes, property combinations and textures. Their outstanding temperature
resistance (-135 ° C to max. +150 °C) makes them suitable for use in both
tropical and Arctic temperatures. Their low intrinsic weight enables them to be
laid over large areas with comparatively lightweight supporting structures. They
are also easy to machine, - they can be sawed, drilled and milled - and have
excellent cold bending properties.
