Waterproof vent construction process

1. After selecting a good Waterproof vent, try to avoid penetration and opening on the Waterproof vent during the construction process, and try to ensure the integrity of the Waterproof vent. If openings or penetrations are necessary, seal penetrations and openings with butyl tape.

2. Since the Waterproof vent has no obvious flame retardant effect, welding should be avoided as far as possible for the connecting parts of the curtain wall project, and the open flame operation (including welding) process should be arranged before the construction of the Waterproof vent, and the open flame, welding or high temperature operation on the membrane should be avoided. If there are special needs, the film should be effectively shielded and heat insulation measures should be taken to prevent the material from being exposed to fire or high temperature.

3. Clean the dust and oil stains on the corner yard before construction to ensure that the corner yard is clean to ensure the bonding effect between the corner yard and the Waterproof vent. If it cannot be cleaned, the Waterproof vent and the base layer are not strong, which will affect the airtightness of the Waterproof vent. sex. When the corner yard passes through the Waterproof vent, the integrity of the Waterproof vent should be ensured as much as possible. The waterproof vent curve flooding completely seals the corner yard with the Waterproof vent. The bond between the seal and the corner code is not less than 2cm.

4. When laying the Waterproof vent, the loose laying method can be selected according to the actual situation. The Waterproof vent and the insulation cotton are fixed with rock wool nails. The rock wool nails at the fixed place are sealed with butyl tape, and the size of the sealing area is butyl Tape completely covers the nail head as standard.

5. During the construction of the roof, the laying of the Waterproof vent should be along the downstream direction of the roof, and the lap length should be 10cm. When the high-strength aluminum alloy bracket of the roof passes through the Waterproof vent, the aluminum alloy bracket and the Waterproof vent junction. Use butyl. The strip wraps around a circle to seal. In addition, the Waterproof vent should not be exposed to UV light for a long time, and the exterior finishing work should be completed as soon as possible.
