Main purpose

Sealing overlaps of Solitex Fronta Quattro and Solitex Fronta WA membrane

Use it on

External timber frame open clad walls with Solitex Fronta Quattro membrane and Solitex Fronta WA membrane.


Tescon Invis provides a permanent seal for overlaps in Solitex Fronta Quattro and Solitex Fronta WA membrane. It is a plain black airtight tape with nothing printed on the top side, so is ideal for use on timber frame buildings where the membrane and tape can be seen through gaps in external cladding (open jointed cladding).

Where to use it

Tescon Invis is a 60mm, 100mm or 150mm wide pure black breathable airtight tape designed primarily for use with Pro Clima’s plain black external windtight breather membrane Solitex Fronta Quattro and Solitex Fronta WA.  The plain appearance is ideal for when the tape and black membrane can be seen through gaps in open cladding installed on the exterior of a building.   

Apart from the colour and plain design, Tescon Invis is identical to Tescon Vana, a tape that has been tested and certified to last 100 years.  The two tapes have the same solid acrylic glue and can be used in exactly the same way.

What it does

Pro Clima Tescon Invis tape provides a fully windtight watertight seal at all overlaps, edges and junctions of any airtight or windtight membrane.  The solid acrylic glue is unaffected by rain, moisture and the weather.  It can be safely exposed to UV for up to 6 months during construction before the external cladding is installed.

The 100mm and 150mm sizes are useful for sealing wider gaps, patching damaged membrane, sealing adjacent lengths of membrane where a recommended overlap of 100mm cannot be achieved,  sealing over large holes (e.g. the holes needed for installation of cellulose or wood fibre loose-fill insulation) and for roof valleys and ridges. 

Why we love it

Tescon Invis is entirely black with no printed lettering or branding on the top side.  This makes it almost invisible when seen through gaps in cladding installed over Solitex Fronta Quattro.  It combines vapour openness and weather resistance with a clean aesthetic.

The bond created by Invis, like all Pro Clima tapes, gets stronger over time.  After 24 hours, you will not be able to remove the tape.  You will get a permanent seal that lasts for the life of the building.

How to install

Ensure the face of the membrane is dust, grease and silicone free.  Cut a manageable length of tape, then remove the release paper.  Apply the tape being careful to avoid wrinkles.  Ensure a Pressfix tool is used to fully adhere the tape to the face of the membrane.

Hints and Tips

Where Tescon Invis is accidently applied with too much overlap around window and door frames (so it was visible after plastering or final finish is applied), the excess tape and its adhesive residue can be removed with Pro Clima Glumex Adhesive Remover. 

Tescon Invis can be used for repairing items in and around the home.  E.g. bags, suitcases, carpet, clothing etc.
