Sealing top, together with sealant and sealing strip, is one of the important auxiliary materials in door and window sealing. Its structure is not complicated, the upper end is a strip (fluff) synthesized by polypropylene filament and polypropylene film, and the lower end is a base made of polypropylene material. The sealing wool top formed by the perfect adhesion of the two is mainly used to seal sliding windows, prevent dust and insects.
Seal top selection
1, be sure to choose a silicified top.
Silicified roof is the premise of buying sealed roof in home improvement. The polypropylene fiber (fluff) of non-silicified top is not treated with silicone oil. Although it is cheap, it is easy to absorb water, and the fluff will collapse after absorbing water. It is easy to lose hair, and how long it may become "bald"; In this state, the sealing effect of non-silicified tops is poor and the service life is not long (3-5 years). After long-term use, they are likely to be weathered into sand ... Peng Ge does not recommend this.
2. Brand
The quality of top products under regular brands is still trustworthy. For example, the more reliable top brands, such as Jialong, Xian 'an, Dinggu, Gan Chun and Gao Shida, can give consumers certain product protection.
Step 3 look and feel
The sealing top is generally installed around the door sash or windshield, and at the position of sliding up and down. In the use of sliding doors and windows, if the sealing top is tight and the gap between doors and windows is "blocked" tightly, we can obviously feel a kind of resistance in the sliding state.
To see if the sealing top used on the sliding door window is full, you can try to twitch. If the sealing top is "displaced", it is proved that it is not completely installed. Whether the tops of two window sashes are closely attached or not, if there is a gap between them, it will also affect their sealing performance and make the sealing top useless.
