【 Building materials network 】Speaking of summer and rain, doors and windows The frequency of water seepage and leakage is high, which can be solved fairly. door window The leakage problem that often occurs and often lies down should be considered as Sliding window Has. After all, the sliding window and the whole window wall If the sealing property of is not good, there will be "gaps" in the rainwater. Suifu doors and windows once wrote about installation and waterproofing in "There is a reason for water leakage at the window sill! In addition to assembly, doors and windows should also be selected for waterproofing". Today we continue to talk about sliding windows and waterproof sealing.

They say that doors and windows without sealing are not good. Then came the question: how to strengthen the waterproof and sealing of sliding windows? Look at the following points -

1. Sealing wool

The sealing wool top is a strip made of high-quality random polypropylene as raw material, which is combined with (silicified) polypropylene fiber and polypropylene film; It is often used in Sliding door /On the window frame or door leaf. The sliding door and window sash are like inverted concave characters, and the sliding door and window frame are like side-by-side concave characters. There will be a gap of 4 or 5mm between the sash and the frame. If there is nothing to fill the gap, the outdoor dust, air and sound will enter through the gap. The wool strip installed on the door and window sash can block the gap and greatly reduce the air intake——

When choosing the sliding window, we need to pay attention to whether the wool of the product fits: if it is too short, there will be gaps, and if it is worn, it is not worn; Too long words affect daily pushing and pulling; In addition, we also need to see whether the top hairs are even and dense, and the hair clusters are straight. High quality wool top shall be firmly bonded, with high resilience, and free from defects such as missing wool, deformation or uneven concave and convex.

2. Drain hole

Push and pull Window rail The design of channel and drain hole is also considered as the sealing category of the whole window. In the drainage design of sliding windows, the design of high and low rails is more conducive to channeling rainwater to the outside to prevent rainwater from silting up in the rails and causing internal irrigation or (wall) seepage. (Side hung, sliding) The blockage of the window drain hole is also the common cause of water leakage and seepage of doors and windows; For window frame row water tank The problem of water leakage caused by blocking is as long as the drainage channel is kept unobstructed daily.

3. Sealant strip

When it comes to the sealing performance of push-pull, many people first think of the sealant strip. The sealant strip plays a vital role in the sealing of doors and windows. If the quality of the sealant strip is too poor or the sealant strip is aged and cracked, the water leakage of doors and windows will often occur.

If sliding window is found at ordinary times sealing material (such as rubber strip) aging, cracking or falling off, it is necessary to re apply the sealant or replace the EPDM sealant strip with better quality.

As for the sealing performance between the sliding window and the wall, refer to the following article: Don't worry about rainy days! There are different solutions for various water leakage problems of doors and windows.

4. Window corner and section glue

If the end glue is not applied for waterproofing when the frame, fan assembly angle and the center sill of the sliding window are spliced with the frame, then water leakage will often occur. The four corners of the window sash and the joint gap between the mullion and the window frame are usually the "convenient door" for rainwater to enter the room. If the machining accuracy is poor (large angle error), the gap will be enlarged; If the gap is not sealed with section glue, the rainwater will be popular.

The sealing effect of sliding window is not good Casement window Therefore, when facing the wind and rain directly, it is often easy to have water ingress into the window and wall wetting. However, as a door and window product with good cost performance, it can also be windproof, dustproof and rainproof as long as the details are well done. When purchasing a sliding window, attention should be paid to the sealing of the whole window: 1. Whether the drainage hole of the sliding window is sealed; 2. Whether there is air leakage treatment at the gap of the sliding window track groove (such as a windbreak: installed on the sliding window track to reduce the air leakage of the track); 3. Check whether there is sealing treatment between window frames (whether it is embedded design); 4. Whether there is wind proof treatment at the contact overlapping position between the window sash and the window sash, and between the window sash and the track (such as edge sealing cover: installed at the contact position between the sliding window sash and the track, which can play the role of concealing the ugly, caulking, and preventing the window sash from shaking back and forth).
