cTrap is a four-layer laminate in the form of a cloth, delivered on a roll. The cloth is attached indoors on walls, floors and/or ceilings, depending on where the emissions are originating. A flooring of your choice can then be laid over the cTrap cloth or, when the emissions are coming from the wall or ceiling, a thin plasterboard. If the emissions are moisture related, the moisture problem must be rectified before the cTrap is installed.
cTrap is a unique composition of four different layers which together effectively stop and bind harmful substances – these may include floor emissions such as 2-ethylhexanol, polyaromatic hydrocarbons (PAHs) from tar products, impregnating agents (chlorophenols, chloroanisoles), volatile organic substances (VOCs), odours, etc. At the same time the cloth allows moisture to pass unimpeded (Z = 200 s/m), which means that the natural moisture balance in the building is not affected. The cloth does not give rise to condensation and therefore no subsequent mould problems. The cTrap is made from recyclable and renewable materials.
The cTrap cloth itself does not contain any chemicals. However, once installed, it captures and adsorbs the particles and chemicals emitted from the building. These pollutants are thus transferred from the building to the cloth. When the cTrap cloth is to be removed – for example if the building is to be renovated or demolished – it is rolled up and sent to incineration where the chemicals are turned into energy instead of leaking into the nature from the deposited building materials.
The inner protective layer has a fluffy surface and is made of non-woven polyester. It is this layer that lies against the source of the emissions.
The adsorption layer is the second layer (going from inside to out) in the cTrap cloth. It is this layer that adsorbs the emissions and sees to it that they stay there.
The polymer layer functions as a barrier which is airtight but still allows moisture to pass through. This barrier makes the adsorption more effective while preventing emissions from outside coming in contact with the adsorption layer.
The outer protective layer is also made of non-woven polyester. It is this layer that will lie against the flooring or the plasterboard which is mounted on top of the cTrap as the final finishing.
