One、 Whether to use glue or sealing strips for door and window systems is better.
When the quality of the adhesive and sealant is consistent, and the workmanship level of the workers and the application method (either glass-based or manual application) are consistent, both methods can be used effectively. Proper execution will not affect the performance or aesthetics.

However, due to the vastness of China and the significant differences between its east, west, north, and south, there may be some variations.
1、In areas frequently affected by typhoons, the bonding strip application process may not be sufficiently secure. Glass can easily shift inward due to strong winds, so it is recommended to use a solid bonding method on the exterior side to ensure a secure connection.
2. In regions with sub-zero temperatures like Northeast China, avoid using adhesive application methods. The quality of the adhesive is not the primary concern; even the most expensive adhesives will crack within three years.
Besides regional differences, from the perspective of door and window manufacturers, there are several potential reasons why different businesses adopt different approaches.
1、Some owners may prefer using adhesive strips due to the following reasons: - Lower technical requirements: Easier to apply and more aesthetically pleasing than applying adhesive neatly. Any worker can easily apply adhesive strips after basic training. - Improved worker safety: All glass is installed indoors, eliminating the need to go outdoors. - Easier replacement: Replacing glass is easier compared to applying adhesive, as the adhesive strips can be simply removed, and the glass can be easily taken out and replaced. - Pre-installed and pre-drilled: Adhesive strips are pre-installed on the window frame or sash before leaving the factory, and the necessary drainage holes are already pre-drilled, eliminating the risk of water leakage due to improper sealing.
2. Some clients say that applying putty is a good solution, possibly because: their products are designed in a way that makes it difficult to apply sealant strips, or because some clients believe that applying sealant is slightly cheaper, as it saves time and labor compared to installing sealant strips, where the time it takes to install one sealant strip for a single glass is sufficient for a skilled technician to apply four similar-sized glass sealant strips.
Two. Differences between applying adhesive and installing sealant for windows.
Aesthetic and secure glass fixing. Choose based on your specific needs. Provides better sealing, but the quality depends heavily on the installer's skill. If the installer is skilled and the adhesive is of good quality, it is recommended to use adhesive.
Due to the limited availability of skilled workers and the inherent instability in aesthetics, many doors and windows are opting for veneer strips. While this method offers stable processing, it's crucial to select high-quality veneer strips. Otherwise, if the drainage system is inadequate, the veneer strips may deteriorate and cause water to accumulate inside the profile, leading to window leakage.
