With increasing oil prices, climate change, CO2 regulations and building regulation codes on fire resistance, nonwovens are providing cost-effective and efficient solutions to building and construction challenges.
Non-perforated, nonwoven polymeric housewrap material decreases air infiltration, resulting in increased energy efficiency and maximum moisture control, while at the same time providing savings for the builder and homeowner during installation and after-sale. Housewrap developments such as translucency, which helps lower installation time and provides high strength, combined with no VOC (volatile organic compound) release in either production or application, satisfy ever more strict government sustainability programmes.
Nonwovens are also responding to the developments in both the flat and pitched roofing markets. More and more demanding building standards, energy-saving schemes and to some extent changing weather patterns are driving the need for breathable and impervious underlays for pitched roofs and an improved basis for bituminous membranes, both of which can best be served with versatile nonwovens.
The growth of nonwovens in the construction industry as facings for plaster boards, for increased thermal and sound insulation, for panels in cavity walls and for floor and wall coverings is an indication of their success in building applications.
