Nassio

Descriptiopn
It is a light three layered waterproofing membrane which allows water vapor permeability while blocking water and
wind. The “breatech” film, the mid-layer, serves as the main stratum of the membrane. Its microscobic pores provide
moisture permeability, while blocking water molecules which are larger in size. Upper and lower polypropylene layers do
not only protect the main stratum, but provide resistance against various construction conditions as well.
Usage Areas
• It is used in hot or cold hipped roofs with any type of pitch.
• It is used between the facing and the thermal insulation layer in siding and other types of curtain walls.
Advantages
• NASSIO is produced in two colors to make it distinguishable from single layered products. Alternative
products offered as breathable waterproofing sheets must be checked for colors (the two faces of the sheet must be in
different colors) as well as for the technical specifications.
• NASSIO removes moisture from the building: It allows water vapor permeability as if there is no membrane and prevents the formation of mildew and bacteria.
• It keeps the thermal insulation materials dry, and thus improves the durability of the structure.
• NASSIO waterproofs: It is impermeable against rain and snow.
• It blocks air currents. With NASSIO it is possible to create a breathable atmosphere even in closed roofs so the roof does not have to be open. This provides energy saving byimproving thermal insulation productivity because there is no
need for aeration in the roof.
• Compared to bituminous membranes used under tiles, it isvery light in weight.
• With higher strength and lower elongation, it is resistant to  tearing.
• It is easy to apply.
• It is durable.
• It requires less stock.
• Because it is manufactured 1.6 meter wide, there is no loss of material.
• Production is available in a range of 80/90/100/110/130g/m2 in terms of surface weight.
Application
Hipped roof (hot roof, cold roof): After having applied NASSIO onto the insulation material, you can easily tile your roof. With NASSIO you do not only waterproof your roof, but thanks to its breathability which removes the air humidity from the roof, you are also able create a dry, healthy atmosphere, and thus NASSIO helps protect the wooden parts of the roof, and improve the durability and performance of thermal insulation boards.
Siding and Curtain Wall Systems: Applying NASSIO onto the thermal insulation materials provides a comfortable atmosphere. Thermal insulation performance improves, and the system becomes much more durable. NASSIO can be safely used in curtain walls thanks to its superior mechanical and vapor permeability characteristics.
Consumption
Consumption Calculation:
Geotextile required can be calculated by the following equation: Consumption = Area x (Roll width + Overlap) / Roll
width For example: Geotextile required for a 2000 m2 area
(with 1,60 meter roll width and 10 cm overlap) is: 2000 m2 x (1,60 m + 0,10 m) / 1,60 m = 2125 m2
Packaging
1,6 m x 100 m roll = 160 m2/roll
