Tittle:
Vapour permeable hydrophobic laminates for roofing systems with nano-fibrous membrane ensuring area weight circa 40 g/m2.
Summary:
A Czech university has developed a vapour permeable hydrophobic laminate suitable for roofing systems, equipped with special nanofiber membrane that helps to decrease area weight by 50% and notably increase insulation properties. The material exhibits a W1 class water repellency (EN 1928), area weight is circa 40 g/m2. The university searches for roofing systems manufacturers to license the technology.
Description:
Current vapour permeable laminates used for technical applications typically include a layer of spunbond and PP membrane that allows to withstand water column = 1500 mm H2O. Surface weight ranges between 90 - 150g/m2

A Czech university has developed a vapour permeable hydrophobic laminate based on polypropylene nonwoven and nanofibrous webs. It is suitable, for example, for roofing systems because it is equipped with special nanofiber membrane that helps to decrease surface weight by 50% and increase insulation properties.

The parameters of the novel laminate are:
- Water permeability: 0,02 - 0,03 m, EN ISO 12572; resp. = 1500g/m2/24h
- Resistance to water: W2 in minimum
- Resistance to the air: = 0,1 (m3/m2 x h x 100Pa) EN 12114
- Temperature resistance: -30°C / +90°C
- UV radiation resistance
- Wear-and-tear resistance = 90 N (EN 12310-1)

The material exhibits 2 - 3 times lower weight when compared to the conventional roofing membranes while it still reaches W1 class of water repellency (EN1928). Production costs are competitive.

Production of the material can be scaled up to the industrial production level (all production parts are available).

The university searches for roofing systems manufacturers to license the technology.
Advantages and Innovations:
- The laminate incorporates polymer based-nanofiber breathable web
- High vapour permeability and higher water repellency
- Area weight is significantly lower (circa 40g/m2) when compared to
conventional roofing membranes (90-150g/m2)
Stage of Development:
Available for demonstration
