Recommendations for the rehabilitation of contaminated buildings

Valutect may be used to seal or coat large areas of buildings such as walls, ceilings and floors for protection against immission of contaminants, including halogen-organic compounds e.g. Per, Tri, PCB, PCP, chloronaphthalene and other pollutants e.g. nitrosamine and formaldehyde.

The indiscriminate use of such substances over a number of years, especially in the 1960’s and 1970’s led in some cases to extensive contamination in buildings.  Such inherited pollution of indoor air is a hazard to human health. Even if the primary source, e.g. in permanently elastic joints, is completely removed, hazardous secondary contamination remains.

Independent long-term laboratory tests indicate that even under extreme conditions Valutect provides an ideal barrier layer with a retardation capacity of not less than 99.5%. Valutect is considered practically technically impermeable and provides a long-term solution for contaminated buildings offering major advantages. Other procedures, which may be expensive and involve elaborate protection measures, are no longer required.

Valutect has almost no subsequent effect on the atmospheric environment in schools or offices, for example. In any case, significant changes in the atmospheric environment can only be brought about by ventilation.
Valutect insulating foil therefore provides a hitherto unknown and unique possibility for the rehabilitation of contaminated buildings. It is an easy, effective, long-term solution that can save considerable costs.

Valutect has very high tear strength so that damage to the insulation by tearing or perforation is practically to be excluded.

Valutect is odour-neutral, non-toxic and ecologically safe.

No particular measures are required with regard to fire or explosion protection. The polyethylene content is subject to the German fire classification B1.
Residual material may be disposed of as normal household waste.
