If you want insulation for doors and windows, the three seals must be intact

Worried about the windows leaking both air and rain? When choosing doors and windows, it is important to understand whether the manufacturer has achieved three seals!

If you still don't know what three seals are. Let's take a look at this note

The first step is the sealing strip on the glass fan, which also refers to the place where the outer sealing strip of the glass opening fan is pressed against the profile sub frame. This step mainly plays a waterproof role. At the same time, there is a drainage outlet at the bottom of the window to allow rainwater to be discharged in a timely manner, with a sealing rate of 95%.

The second layer is the middle pressure adhesive strip, also known as duckbill adhesive. It divides the door and window frames into airtight and waterproof chambers, forming a pressure equal drainage effect to prevent rainwater from seeping into the room, while also preventing air and moisture inside the door and window frames from leaking out. The sealing rate reaches 4%.

The third step is the water blocking edge and sealing strip on the window frame, which can further enhance the sealing performance of doors and windows, and prevent water leakage and seepage between door and window frames and walls, with a sealing rate of 1%.

Overall, the advantages of three seals are that they can improve sound insulation, thermal insulation performance, and prevent water infiltration.
