How to Select the Right Tape
You know you need a great tape and you know Pro Clima tapes are the best. This rundown will help you select the right tape for the job at hand. If you need complete information, specifications and installation instructions click the product pages linked in each description below.
So let's break down your taping needs by which basic components you're taping. In order of appearance:
- Exterior Walls & Basements
- Exterior Penetrations
- Window Penetrations
- Interior Ceilings, Walls & Floors
- Interior Penetrations

Roof membrane to membrane(SOLITEX) and to wood: TESCON Vana
TESCON Vana is a pressure activated SOLID acrylic adhesive tape. It is available in a variety of widths.
Between roof battens and membranes with penetrating fasteners: TESCON NAIDECK
TESCON NAIDECK is a self-sealing double sided butyl rubber adhesive tape.
Roof Sheathing (Wood Fiberboard, OSB, Plywood, Exterior Gyp Board): TESCON Vana
Note on Primer: Sheathings, particularly wood fiberboard or OSB may be rough and/or porous and will require the application of Pro Clima's Primer RP to ensure a robust bond. Test application of TESCON Vana by pressurizing tape, waiting several hours, then peel and verify tenacity of bond. Typical OSB does not require a primer while typical wood fiberboard does require a primer.
EXTERIOR WALLS & BASEMENTS

Sheathing (Wood Fiberboard, OSB, Plywood, Exterior Gyp Bd): TESCON Vana
See note above regarding primer.
Membranes (SOLITEX behind closed joint rainscreen): TESCON Vana
Membranes (SOLITEX Fronta Quattro behind open joint rainscreens): TESCON Invis
TESCON Invis is functionally the same as TESCON Vana, but is black and has no writing on it.
Membranes (Poly sheets): TESCON Vana
While most poly sheets can be taped with TESCON Vana, with excess residue on the poly sheets adhesion can be unsatisfactory. Quality of adhesion should be confirmed with an adhesion test.
TESCON Vana + Primer RP is the vapor open option. Use Extoseal Encors if a flexible, tough, but vapor closed connection will work best or if working below 40F. In warmer weather you can also use Extoseal Finoc to air seal sheating to foundations/slab or under sills in timber structures. It creates a cost effective, durable, self sealing capillary break.
Poured Concrete (to Membranes): recommended CONTEGA HF caulk adhesive, with an expansion loop in the membrane. Alternative is TESCON VANA and Primer RP.

Kaflex Mono or Duo (one or two wires)
KAFLEX Multi: Multiple Wires (up to 16 cables)
Small pipes (.5" to 1.5" dia): above TESCON tapes and Roflex 20
Roflex 20 is an EPDM gasket with integral TESCON Vana adhesive connection.
Roflex 30 - 300 are EPDM gaskets that require separate tape connection to air barrier.
Installing TESCON Profil tape at window to INTELLO membrane.
Exterior face taping over window flange (U.S. style): TESCON Vana 150
See TESCON Profil blog post on pre-making inside corners, here.
Exterior zero profile taping to side of window frame (before installation): CONTEGA EXO
Window sill pan: EXTOSEAL ENCORS (6,8,12")
Use Extoseal Encors for the sill and up side 4-6"
either taped to front of window frame (Tilt & turn windows that accommodate this)
or under the full window frame to a back dam or end of the slope of sill.
Window buck rough opening jambs and head: TESCON Vana

All exterior material connections noted above, plus:
Membranes (INTELLO, INTELLO Plus or DB+): TESCON Vana
See this blog post for taping INTELLO Plus or DB+ for dense pack cellulose installations.
That's it! To simplify things further - note that TESCON Vana is capable of handling the vast majority of most typical tape needs. Often with just a roll or two of a few other tapes, a few gaskets, some primer and adhesive caulking - and you have a complete taping system to make all the connections you need. If you have any questions please don't hesitate to contact us.
One last thought: Be sure to have a handy PRESSFIX tape applicator on hand to ensure proper pressure activation of tapes.
* KAFLEX DUO was made with UNITAPE, if used on exterior, please cover with TESCON VANA for waterproof adhesion.
