Installations

The cTrap can be installed on floors, walls or ceilings depending upon from where the emissions are spread. An indicator that the indoor air is not healthy is an abnormal heavy odour, however odourless pollutants can also result in health problems. cTrap captures the emissions whether they are identifiable by smell or not.

cTrap is a flexible solution, as any type of surface layer can be mounted on top of the cloth – the choice is yours. If you choose to remove for example existing vinyl flooring and the concrete floor underneath is damp you must first clean the concrete surface thoroughly before placing an appropriate moisture barrier (such as a thin polythene or polypropylene sheet) on the concrete under the cTrap. The moisture barrier must have a higher Z value (s/m) than the overlying layers.

See our installation instructions.

Regarding installation on the ceiling and walls, the cloth is usually secured with a staple gun or battens. The cloth is then covered with gypsum boards and surface finishing.

Following complaints from staff and pupils an investigation was carried out which identified emissions from the floors on all levels. cTrap (550m2) was installed on the two upper floors directly onto existing vinyl flooring and then covered with a floor lining and new vinyl flooring.

During a total renovation of the school, emissions were found in wooden beams on all floors. In conjunction with the renovation it was therefore decided to install cTrap (1200m2) to insure against possible future problems with the indoor air.
