Product Description
The properties of landfill gases are principally determined by the presence of methane and carbon dioxide and any air that these gases are mixed with. The migration of these gases, as a result of diffusion and pressure flow, have increased in recent years and present a risk to both health and safety in new and existing buildings.
Radon enters buildings by airflow from the underlying ground. The two methods for sealing against Radon are the passive system, normally achieved by increasing the airtightness of the damp protection within the floors and walls, and an active system, which requires providing a powered radon extraction system by means of an integral fan.
