Physical Attributes:

• UNI is a nonwoven, absorbent, water-resistant 180 GSM, synthetic wall underlay.
• UNI is water-resistant and designed to provide temporary protection from weather conditions and UV exposure to timber framing, without the installation of the cladding, which allows for the continuation of internal work on the build for 90 days after installation. 
• UNI comprises three polypropylene layers: two outer layers of non-woven polypropylene with a middle layer of a functional-technical film. It is manufactured to meet the European standard EN 13589-1:2014 as well as the absorbency performance requirement as per NZS 2295:2006.
