PROSOCO Targeted Interior Air Seal | Stops air Leakage from The Inside (Yellow, 5 Gallon)

PROSOCO’s Targeted Interior Air Seal (TIAS) seals critical building envelope connections quickly from the inside of a structure to achieve the same performance and continuity of air control expected from an exterior air-sealing application. Applied from a variety of equipment types, TIAS is an elastomeric, water-based air sealant that is installed after the exterior sheathing and before interior drywall or paneling. Designed for negative-side air control strategies, TIAS works on new and existing construction.

• Install TIAS around all through-wall penetrations and along joints and seams that separate conditioned from non-conditioned spaces where air leakage is most likely to occur. This includes, but is not limited to, seams that separate:
• Over joints and seams in ceiling, walls or floor planes. The mudsill from the concrete slab.
• The bottom plate from the mudsill. The bottom plate from the sheathed floor assembly.
• The top plate from the second top plate. Around through-wall pentration(s).
• Properly installed, TIAS penetrates deeply and seals gaps in construction that can compromise building performance and durability. TIAS maintains its air-sealing function long after interior spaces are conditioned and occupied.
