PRODUCTS: Tests Abstracts
A series of tests carried out worlwide, has been supplemented by tests carried out in accordance with relevant British Standards and American
Standards and these have indicated the total suitability of the material for roofing and cladding.

These are only some of the tests in which Onduline has performed entirely satisfactorily. Full test details are available from our offices.
