Some of the greatest advances often take a surprisingly simple route to a solution where others have attempted to use complexity. So it is with damp removal. Homes are constantly disrupted by companies tearing into the walls and laying extensive plastic sheets to try and keep damp at bay. In the meantime, the Schrijver System has been developed so that small plug-in vents on the outside of the house can do a far more effective job, more cheaply, and with less disruption. Frank Schrijver UK has now brought this technology to Britain for the first time, and it will change how many homes do their damp proofing.
