Where to use it

Pro Clima Duplex double-sided adhesive tape can be used to seal laps between roof, wall, floor and ceiling membranes and in junctions to hard surfaces such as steel or timber beams.

What it does

Duplex provides an airtight and weatherproof seal for membrane overlaps with other membranes and on overlaps with smooth hard surfaces of other structural elements like beams, joists or studs.  

Why we love it

Pro Clima Duplex tape is highly versatile and can be used internally or externally. It is reinforced with super-strong mesh and provides an excellent airtight and watertight seal for membrane overlaps. Duplex allows overlaps to be sealed “invisibly” making a very neat installation. 

The water resistant double sided tape has achieved the best possible VOC (Volatile Organic Compound) rating which means it has minimal impact on indoor air quality and is excellent for the building occupants and installer’s health.

How it works

The release paper on one side is removed first then the Pro Clima Duplex tape is applied onto the lower of the two surfaces. After the second release paper is removed, the membrane to go on top is positioned above then pressed down firmly to become permanently stuck to the lower surface.
