We are often asked to recommend remediation of Butyl Rubber Roofs Upgrading of these systems to modern standards is possible if you stick with Nuralite.
The first think to consider is insulation. Older buildings had very little insulation and it is a cost effective time to provide additional insulation before installing a new membrane. Nuralite would recommend using Enertherm PIR Insulation Boards
which can be fastened directly onto the existing membrane. Tapered boards may be used to create a fall if there is currently ponding issues with the roof. Nuraply 3PM
may be installed directly over the Enertherm boards.
If Enertherm is not being used, we require the butyl rubber to be stripped off so that we can ensure excellent adhesion between the new membrane and the plywood substrate.
