Product Installation

All the products in this range must be welded to provide a watertight and gas-resistant seal. Welding is an essential requirement because hydrocarbons can affect the long-term performance of butyl and bitumen tapes.

In all cases, the installation of Sikaplan® VOC Gas Barrier membranes should be completed by a suitably qualified and accredited installer (NVQ level 2) and independently validated in accordance with CIRIA C735:2014.
