IKO ULTRA Prevent 25 systems can be used as a hybrid system or a torch applied system, ensuring the product is prepared for both the site conditions and project requirements.
With their reinforced bituminous membranes, the IKO ULTRA Prevent 25 systems achieve waterproofing functionality and a life expectancy in excess of 25 years – BBA approved (Certificate No. 91/2671).
These systems are backed with a 25-year guarantee when installed in line with the specification by IKO Approved and Registered Contractors only.
They are also classified BROOF(t4) in accordance with BS EN 13501-5: 2016 fire classification. This enables unrestricted use within Part B4 of the Approved Documents of the Building Regulations (tested under ENV1187).
This is based on specific system build-up testing, so please contact IKO for further clarification or refer to the product BBA certificate, where applicable.
