New Flashing Tape Performs in Extreme Weather Conditions


40 Below is compatible with all building wraps, passes nail sealability to ASTM D3330 and is suitable as a single layer application over timber framing. The 75mm tape size is also tested and approved for sealing the joints on Rigid Air Barriers.


40 Below has incredible adhesion in all conditions and works in temperatures from -40°C up to 65°C. CodeMark has passed 40 Below for NZS3604 Building Wind Zones up to and including 'Very High'.


40 Below is quick to install with its four step installation process. 40 Below is a hot melt adhesive tape and therefore only 0.2mm thin. This allows for easier fitting of windows and doors. An optional corner guard is easy to install and increases protection to framing.
