Wallpaper absorbs pollutant from air and old building construction

Sustainability Aspects: It is sustainable to keep buildings as long as possible, but old structures come frequently with high levels of toxins and other pollutants. This wallpaper not only covers them up but takes them out of the air and capsules them in.


Pollution due to contamination in building interiors continues to be a relevant topic. Numerous studies have proven that off-gassing in interiors has a considerable impact on our health and well-being. Headaches, nausea, and dizziness are just a few of the less serious symptoms. These toxic contaminants are released largely by construction and auxiliary materials used primarily in the 1960s and 70s.
Typical contaminants include:

  • PCB (additive in joint and sealing compounds to increase flexibility)
  • PCP (disinfectant and fungicidal additive in wood preservatives)
  • Pesticides and insecticides (used in wood, to preserve artworks in churches and museums etc.)
  • Radon (from masonry containing uranium, walls, and floors)

Occupants of former paint shops, tyre warehouses, and dry-cleaners in particular are exposed to various contaminants released into the atmosphere.
Owners of buildings proven to be polluted generally must count on a reduction – usually substantial – in the value of their property.

SARATECH® Permasorb® is a breathable adsorptive wall covering from Blücher. The concentration gradient between the contaminant-laden wall and the adsorber layer automatically initiates a diffusion process. Noxious gas molecules migrate towards the room interior, make their way into the adsorbents, and are bonded safely and permanently. The process only stops once the gradient is eliminated and the wall is free of contaminants. The large adsorptive capacity of the wall covering ensures safe adsorption even over a very long period and even in highly contaminated buildings.
SARATECH® Permasorb® is superior to traditional decontamination methods since ground-up renovations are generally very expensive and building downtimes are long. Various sealing methods can cause moisture and mildew to build up because the seal acts as a barrier, and these methods leave toxins in the wall. Even minimal damage to the barrier can result in intense off-gassing of toxins at any time.
