The A Proctor Group has launched its new range of gas resistant membranes. Mike Sweeney of the A Proctor Group commented: “The membranes have been specifically developed to simplify the process when choosing the correct gas membrane for your site.” <br> <br> Historically, the type of gas membrane chosen was determined by the type of gas present on site. This is no longer the case as the type of membrane can now be chosen based upon the gas screening value (GSV) of the gas. <br> <br> The A Proctor Group can now offer a cost effective range of membranes to suit the GSV and characteristic situation of a site, along with pre-formed corners, jointing tape and all accessories required to ensure the future safety of building occupants<br> <br>
