How does cTrap perform in comparison to other sealants?

cTrap is an emissions barrier but not a moisture barrier. The cTrap cloth takes care of and binds emissions such as particles, organic substances and odorants, while moisture passes through the cloth virtually without hindrance (Z=200 s/m). cTrap allows the emissions to escape the construction and hence the building to “clean itself”. As the cloth is moisture permeable the cloth can be applied to any base without causing damp or mould problems.

Is cTrap an environmentally friendly product?

Yes, the cTrap contains no chemicals and no chemicals are utilised during cTrap installations. It is important to us that the product we work with is chemical free. Handling of chemicals constitutes risks to humans and the environment; furthermore, the building will eventually be demolished at which time there is a risk that the chemicals will leach out of the materials and end up in the groundwater. All of this can be avoided by using cTrap.

Does the cTrap have any limitations?

The cTrap cloth allows moisture through but should not be closed into a damp environment (RH>75%). On the application of cTrap to a damp concrete floor therefore, a suitable moisture barrier must first be laid (such as 0.2 mm polythene sheet or another suitable barrier), then the cTrap and finally the flooring of choice.

Can the cTrap cure the “sick building” syndrome?

cTrap can eliminate or reduce the health problems associated with occupying a house that is “sick”, for example after moisture damage. Research has shown that the cTrap efficiently blocks particles and particle borne substances of volatile organic compounds (VOC). The indoor air becomes noticeably fresher almost immediately (minutes or hours) after installation. We get many grateful comments stating that problems such as headaches, coughs, asthma, skin irritation etc. have disappeared or substantially diminished, following the installation of the cTrap.

Where can I buy cTrap and how is it installed?

You can buy cTrap by ordering from us via e-mail or by telephone. We recommend that you first consult a professional investigator to locate the source of emissions and identify possible moisture problems. cTrap should be installed on the surface from which the emissions are spreading. Installing cTrap requires precision. cTrap has a smooth and a fluffy side, and it is the fluffy side that should face the building (the cloth adsorbs from this side only). The cloth is secured with a staple gun or tape; no chemicals are used. If cTrap is applied to a damp cement floor a suitable moisture barrier must first be laid (e.g. a 0.2 mm polythene or polypropylene sheet), then the cTrap. Flooring such as laminate or parquet is then laid directly onto the cTrap cloth, but if you wish to install a vinyl flooring it is necessary to have an underlay between the cTrap cloth and the new flooring. Mounting cTrap on walls or ceilings is done in a similar way. On top of the cTrap cloth, suitable 6 mm gypsum boards can be fixed which can then be painted or papered as desired. cTrap is a risk free product to use as it is moisture permeable.
