APPLICATION INSTRUCTIONS

INSTALLATION

Sikaplan®-1650 DPM Gas Barrier should be installed in accordance with the product installation guidelines, and in accordance with BS 8485:2015+ A1:2019.

JOINTING AND SEALING

It is recommended Sikaplan®-1650 DPM Gas Barrier be heat welded where possible, with welding carried out by competent personnel with suitable qualifications in accordance with best practice, and guidance contained within BS 8485:2015+ A1:2019. Sikaplan®-1650 DPM Gas Barrier should be overlapped by at least
100mm. If taping joints, only suitable tape must be used, ensuring application with a silicone roller to remove trapped air. Pre-formed details, or Self Adhesive Gas Membrane are available for sealing around protuberances.
