PTFE waterproof breathable membrane, as the name suggests, has excellent waterproof performance and breathable performance. It is also the most popular one at this stage. Very popular environmentally friendly material.
Since the waterproof and breathable membrane has no obvious flame retardant effect, welding should be avoided as much as possible for curtain wall project connections. Open flame operations (including welding) should be arranged before the construction of the waterproof and breathable membrane. Open flame operations (including electric welding construction) are strictly prohibited near the waterproof and breathable membrane. ). When laying the waterproof breathable membrane, you can choose the laying method according to the actual situation. Fix the waterproof breathable membrane and the thermal insulation wool with rock wool nails. The rock wool nails at the fixed location are sealed with butyl tape. The area of the sealing area is sealed with butyl tape. Full nail head coverage as standard.
The working principle of ptfe waterproof and breathable membrane is: in the state of water vapor, water particles are very small, and these water particles can penetrate along the capillary tube to the other side, causing vapor permeability. If water vapor condenses into water droplets, the particles will become larger, and the surface tension of the water droplets will act, and the water molecules will not be able to smoothly leave the water droplets, penetrate and reach the other side. In other words, this process can prevent The occurrence of water penetration makes the PTFE waterproof and breathable membrane truly have a waterproof function.
