Air Sealing & Flashing Tape
Overview
Air Sealing & Flashing Tape is an airtight and waterproof adhesive tape to cover the joints of sheathings and insulation board.
Structure & Materials
Advantages
◆It is easily rolled back and cut by hand
◆No excessive waste is produced on-site, making the product environmentally friendly
◆Excellent airtightness and waterproofness are achieved
Application Examples
◆For airtightness of the air & water barrier sheathing joint
◆For airtightness of insulation board joint
Air Sealing & Seam Tape 
Overview
Air Sealing & Seam Tape is a single-faced adhesive tape of synthetic fabric backing which is coated by synthetic resin pressure-sensitive adhesive (PSA). It shows the excellent effect fixing of the vapor barrier to create a continuous air barrier and reduces moisture intrusion and accumulation into the wall system. Since the bordering of white synthetic fabric is straight and hand-tearable, the workability is superior.

Advantages
◆ By using high-performance adhesive, excellent air-tightness is achieved.
◆The construction time can be reduced due to being rewound smoothly and hand-tearable.
◆Since there is no release paper, on-site waste can be significantly reduced.
Application Example
◆ Joint tape for vapor barrier/retarder
