9mm OSB Lined Under Onduline
Upgrade your building with a 9mm OSB lining installed directly under the Onduline roof to improve strength, stability and long‑term performance. This additional layer reinforces the roof structure, reduces the risk of sheet bending and provides a cleaner, more durable internal finish. It is an ideal enhancement for stables, shelters, sheds, workshops and garages exposed to changing weather conditions.
The OSB lining is supplied only as part of a new building order and includes full installation carried out during construction. This ensures a precise fit, secure fixing and consistent quality across the entire roof area.
