Profile Materials
Broken Bridge Aluminum: It has good heat insulation and soundproof performance, high strength and corrosion resistance. Its multi-chamber structure can effectively block sound transmission and is a popular soundproof folding door material on the market currently. Broken Bridge Aluminum is a relatively high-quality door and window material. Aluminum alloy has many advantages. For example, its high strength can well block external noise.
Aluminum Alloy: It is light in weight, high in strength, has diverse surface treatments and a certain soundproof ability. Some high-quality aluminum alloy folding doors can further improve the soundproof effect through special sealing designs. Aluminum alloy is light in weight. When installers install it, they can easily put it in place, reducing the installation difficulty and indirectly reducing the economic cost for installers.
Plastic-steel: It has good soundproof performance, a relatively low price, and also good heat insulation and sealing performance. However, compared with broken bridge aluminum and aluminum alloy, the strength of plastic-steel is slightly weaker and its appearance may look a bit monotonous. The soundproofing of plastic-steel is particularly strong. Even if you work or live in a busy downtown area, you can have a quiet environment. Therefore, in view of consumers’ needs and pain points, plastic-steel is a very good material that can well help consumers avoid noise interference.
Glass Types
Double-glazed Hollow Glass: There is an air layer in the middle, which can effectively block the spread of sound and has a good soundproof effect. At the same time, it can also play a certain role in heat insulation. Double-glazed glass also has a heat preservation effect. For example, in cold winter, if you install this double-glazed hollow glass, the cold air outside won’t come in and it will be warmer and more comfortable. And in hot summer, due to the thick glass blocking the hot air outside, the indoor temperature will remain at a constant state.
Triple-glazed Hollow Glass: It has one more layer of glass and air layer than double-glazed hollow glass, and its soundproof performance is better, especially for blocking high-frequency noise. However, the price is relatively high and the weight of the door will also increase.
Laminated Glass: It is composed of two or more layers of glass with one or more layers of PVB film in the middle. When the glass is impacted, the PVB film can absorb energy and prevent glass fragments from splashing, having good safety and soundproof performance, and a good isolation effect on medium and low-frequency noise.
Sealing Performance
Sealing Strips: High-quality sealing strips are the key to ensuring the soundproof effect of folding doors. EPDM (Ethylene Propylene Diene Monomer) rubber strips have good elasticity, aging resistance and sealing performance, and can effectively fill the gaps between the door and the door frame to reduce sound intrusion.
Door Frame Structure: Choose a door frame with a multi-channel sealing design, such as a door frame structure with double or triple sealing strips, which can form a more effective soundproof barrier. In addition, the installation accuracy of the door frame will also affect the sealing performance. During installation, ensure that the gap between the door frame and the wall is filled densely.
Hardware Fittings
Hinges: The quality of hinges directly affects the smoothness and stability of the folding door’s opening and closing, and further affects the soundproof effect. Choose stainless steel or copper hinges, which have good load-bearing capacity and corrosion resistance, and can ensure that the door remains in a good sealed state during long-term use.
Locks: Good locks can not only improve the safety of the door but also enhance its sealing performance. Choose locks with a multi-point locking function, which can make the door close more tightly, reduce gaps and improve soundproof performance.
Brand and Quality
Brand Reputation: Choose brands with high popularity and good reputation. These brands usually have more guarantees in terms of product quality, technological level and after-sales service. You can learn about the brand’s credibility and product quality through online reviews, friends’ recommendations, industry exhibitions and other channels.
Product Testing Reports: Check the soundproof performance testing reports of the products to understand their specific soundproof indicators, such as Sound Reduction Index (Rw). Generally speaking, the higher the soundproof amount, the better the soundproof effect.
Installation and After-sales Service
Professional Installation: The installation of soundproof folding doors requires professional techniques and experience. Improper installation may affect the soundproof effect of the door. Choose merchants with professional installation teams to ensure the installation accuracy and quality of the door. When installing soundproof folding doors, pay attention to the size of the folding door and the door frame. If the door frame is too small, try to seal it with glue or cement as much as possible. The size design of doors and windows should be specific and precise, which can save a lot of time and economic costs during installation.
After-sales Service: Good after-sales service can relieve users’ worries during use. Understand the after-sales service content of merchants, including warranty period, maintenance response time, parts supply, etc., and choose merchants with perfect after-sales service. After-sales service is a very important part of completing sales tasks. It is also concerned with customers’ use, testing of door and window use, and feedback on performance. Based on these feedbacks, improvements are made to make the door and window design more user-friendly and professional.
Regarding after-sales service, after installing the folding doors, conduct online surveys to ask about the use effect, customers’ opinions, how they feel about using the doors and windows, what the effect is, where the doors and windows need to be improved, and what suggestions they have for the design of doors and windows by Dingtuo Door and Window Company.
