IBS OS'Brace RAP Rigid Air Barrier and Protection Panel

IBS OS'Brace RAP is an orientated strand-board rigid air barrier and bracing panel.

IBS OS'Brace RAP is an engineered lightweight composite structural panel made of peeled softboard that is bonded together with a synthetic resin. The panel is treated to H3.1 level using a method where the chips themselves are treated prior to being bonded, meaning that the panel is fully treated.

Key Features

  • Simple to install, lightweight, easy to cut, nail, screw and drill
  • Provides a consistent, high quality bracing panel supported by fast and reliable delivery and service
  • Clean fresh wood appearance with none of the typical veneer defects of plywood such as holes, knots and splits
  • Panels are made in one of the world’s most modern OSB plants in Germany from environmentally sustainable softwood plantation resources
