Aluminium Waterproof Tape Butyl Sealing Tape For Lap Joint Of Waterproof Rolls

Butyl rubber waterproof tape, used for lap joint of waterproof rolls

Product Features:

1. Air Tightness: Adopts closed-cell sealing structure extremely low air permeability, which can effectively block cold air and dust from infiltrating through door and window gaps, reducing indoor heat loss in winter.

2.-Temperature Flexibility: Remains flexible at -15°C without hardening and becoming brittle in low-temperature environments adapting to the deformation of door and window gaps in northern winters.

3. Compatibility: Non-corrosive to various materials such as aluminum alloy, steel, and metal ducts, and will not undergo chemical reactions with door and window sealants.

4. Shock Absorption and Noise Reduction: Elastic buffer that can reduce noise generated by door/window switches and duct vibration, enhancing user

Construction Steps:

1. Base surface cleaning: Wipe the lap joints of upper and lower layers of waterproofing membrane clean, remove the surface release film and dust, and keep it dry.

2. Tape positioning: Paste the double butyl tape on the lap area of the lower membrane, press it with a, then tear off the upper release film of the tape.

3. Membrane bonding Align the lap edge of the upper waterproofing membrane, slowly lower the membrane and repeatedly roll the lap area with a roller to ensure that the two layers of membranes are bonded and compacted via the tape.

4. Sealing inspection: Inspect all parts of the lap edge, confirm that there are no gaps or edges, the lap width is not less than 10cm, and prevent formation of water seepage channels.
