Gas Membrane Lap Tape
Verified by manufacturer 4 months ago
A tape suitable for sealing the laps within membrane installations.
Application
Typically used for the jointing of construction membranes including damp proof, radon and gas resistant sheet membranes for combined ground gas and damp proofing applications.
Description
Lap tape which is manufactured using an aluminium and polythene laminate coated on one surface with an additional layer of self-adhesive polymer modified bitumen.
Features and benefits:
- Incorporates an aluminium foil core to provide resistance to the passage of methane, carbon dioxide and radon gases.
- Adhesion properties to most membrane types and building materials.
- Easy to install, providing a robust method of membrane jointing.
