Choose the product between eterpan BASE and eterpan BASE Sealed
Thickness: 4.5 - 6.0 - 9.0 mm
Dimensions: 2400 - 2700 - 3000 x 1200 mm
eterpan BASE Sealed is finished with a durable and breathable water-repellent on the fair face. eterpan BASE Sealed is the most sustainable option to avoid internal condensation, repell water from the cavity and supply a performing air seal.
eterpan has been assessed by Branz to have in exterior applications
- 15 years durability when uncoated
- 50 years durability with a maintained coating

DO's AND DON'Ts of the Rigid Air Barrier
DO: a rigid air barrier is a barrier against wind and water infiltration from the outside to the interior of the building. For the purpose of well-engineered building physics to avoid internal condensation within the wall, a rigid air barrier has to be vapour OPEN. A vapour barrier or vapour seal has to positioned more to the interior of the insulation to avoid condensation. For that reason, using vapour closed or sealed materials asresin based wood products for rigid air barrier, may create problems in the wall when temperatures outside drop. Ask PBS for more information and graphs based on the Glaser method.
DON'T: paint the rigid air barrier to avoid water absorption. Painting the rigid air barrier will create a vapour barrier and if there is no thermal insulation on the outer side of the wall, will increase significantly the chance for internal condensation within the wall. A far better option is to apply a vapour open water-repellent product to humidity resistant fibre cement.For more information, contact PBS Distributors.
