Overview:
Pro Clima Tescon No.1 is a flexible airtight tape for creating long-lasting airtight seals on airtight membranes and windtight breather membranes. It has been tested and proven to provide an airtight seal that lasts 100 years. Tescon No.1 is perfect for sealing overlaps, edges and penetrations as well as connections to most surfaces commonly found on a building site (primer may be required). It can be left exposed to UV and weather for up to 3 months prior to installing the final external finish on the building.
Where to use it:
Tescon No.1 airtight tape will permanently stick to all Pro Clima interior and exterior membranes as well as any other membrane made from PE, PA, PP, PET and aluminium. Also permanently bonds to planed or painted timber, OSB, plywood, MDF, hard plastics and metal.
When used on wood fibre insulation boards (e.g. Steico), concrete, plaster or smooth masonry, Tescon Primer RP or Tescon Sprimer should be used first to ensure good adhesion. If the surface is painted or may come away, detach or delaminate, we recommend doing an adhesion test first.
What it does:
Tescon No.1 is a flexible airtight adhesive tape for airtight sealing membranes and airtight accessories on roofs, walls and floors.
The backing is very flexible and stretchy so it can be applied on curved surfaces or in curved lines without wrinkles. The flexibility is also great for sealing to OSB as the tape can be pressed more easily into the recesses of the non-flat surface texture. Sealing around pipes and cables is also easier with a flexible tape.
Tescon No.1 is 60mm wide; the perfect width for sealing overlaps with the recommended 25-30mm of tape on each surface.
Tescon No.1 uses solid acrylic glue. This type of glue is fully waterproof and unaffected by changes in temperature and humidity. It has high adhesion and excellent cohesion which means the glue stays together, won’t slip and can provide the longest lasting seal possible. Dispersion glue (used on competitor tapes) reacts to moisture causing the bond to break down relatively quickly (within a few months). Tescon No. 1’s solid acrylic glue actually gets stronger over time and is ideal for building projects in Ireland and UK due to it being unaffected by the wet climate and extreme weather conditions.
Use it on:
Internal or external membranes, airtight accessories, timber, concrete, on walls, roofs, floors and ceilings.
