Product Overview
Soundproof glass for building curtain walls usually consists of two or more layers of glass, with specific soundproof materials or gas layers in between to form an effective soundproof barrier. These glass products not only have excellent soundproofing effects, but also have excellent thermal insulation, heat insulation, UV protection and other properties, which can significantly improve the comfort and energy saving effects of buildings.
Product Features
1. Soundproofing performance:
Soundproof glass achieves soundproofing effects by increasing the path and impedance of sound wave propagation and reducing the ability of sound waves to penetrate.
Soundproofing performance is usually expressed as "sound insulation" in decibels (dB). The higher the sound insulation, the better the sound insulation effect of the glass.
Generally speaking, the sound insulation of double-layer soundproof glass is between 28 and 32dB, while the sound insulation of triple-layer soundproof glass can reach more than 35dB.
2. Thermal insulation performance:
Soundproof glass usually also has good thermal insulation performance, which helps save energy consumption for air conditioning and heating.
Different types of soundproof glass (such as hollow glass, laminated glass, etc.) may have different thermal insulation performance.
3. Safety:
Soundproof glass is generally strong, which can improve the safety of the building and resist impact to a certain extent.
When some soundproof glass (such as laminated glass) breaks, the fragments will be tightly glued to avoid hurting people.
4. Aesthetics:
Modern soundproof glass has beautiful design and can be integrated with the architectural style to improve the overall visual effect.
A variety of colors, textures and styles can be provided to meet the needs of different customers.
Product Types
1. Hollow glass:
It is composed of two or more layers of glass with a dry air layer or other gas layer in the middle.
Advantages: Good thermal insulation performance, which can effectively reduce heat exchange.
Disadvantages: The barrier to low-frequency noise (such as train sound) is weak, and poor sealing may cause condensation of water vapor, affecting the appearance.
2. Laminated glass:
It is composed of two or more pieces of glass with PVB film or other sound insulation materials in between.
Advantages: Excellent sound insulation, especially low-frequency noise; high safety, the fragments are tightly stuck when the glass breaks.
Disadvantages: Thermal insulation performance is slightly inferior to hollow glass; transparency may be affected by the laminated layer.
4. Other types:
Such as coated glass, frosted glass, etc., with additional functions such as privacy protection and heat insulation.
Fireproof glass is suitable for special places such as commercial buildings, with multiple functions such as fire prevention and sound insulation.
Application scenarios
Soundproof glass is widely used in various building scenarios that need to reduce external noise interference, such as:
1. Residential buildings:
Residential buildings near busy streets or transportation hubs, the use of soundproof glass can effectively reduce urban noise and provide a quiet living environment.
2. Office buildings:
Places where you need to concentrate or hold important meetings, the use of soundproof glass can effectively reduce external interference and improve work efficiency.
3. Schools and hospitals:
A quiet learning or treatment environment is required, and the use of soundproof glass can help reduce noise interference.
4. Commercial buildings:
Such as shopping malls, restaurants, etc., the use of soundproof glass can help improve customer experience and reduce the impact of noise on commercial activities.
Installation steps
1. Install curtain wall keels: Curtain wall keels are an important part of curtain wall installation. Curtain wall keels must be installed first, and they must be adjusted and tested to ensure their flatness and verticality.
2. Glass preparation and transportation: According to design requirements, soundproof glass should be customized in advance, and its thickness, specifications, etc. should meet the requirements. During transportation, care should be taken to avoid collision and damage to the glass.
3. Glass cleaning: Before installation, the soundproof glass needs to be cleaned to remove dust and debris on the surface to ensure the bonding effect after installation.
4. Glass positioning and installation:
Use a level and a plumb to accurately measure the installation position and mark the installation point of the glass.
Use tools such as glass suction cups to firmly fix the soundproof glass on the frame, and pay attention to maintaining the flatness and verticality of the glass.
During the installation process, pay attention to the spacing between the glass and the uniformity of the sealant.
5. Sealing treatment:
Use special sealant to fill the gap between the glass and the frame to ensure waterproof and heat insulation effects.
The selection of sealant must comply with building specifications and have good elasticity and weather resistance.
When filling the sealant, pay attention to avoid bubbles and leakage.
6. Install sealing strips:
After the glass is installed, it is necessary to install sealing strips for sealing to further improve the sound insulation, waterproof and dustproof effects.
7. Quality inspection:
Carry out a comprehensive inspection of the installation quality of the soundproof glass, including installation firmness, sealing effect, sound insulation performance, etc. If necessary, water tightness and air tightness tests can be carried out.
8. Regular maintenance:
Regularly maintain and clean the soundproof glass to maintain its good appearance and performance. At the same time, pay attention to check the aging of the sealing strips and sealants, and replace them in time.
FAQ
Q: Poor sound insulation effect
The soundproof glass does not achieve the expected sound insulation effect, which may be caused by improper selection of glass type, installation process problems or excessive noise in the surrounding environment.
A: Improve the sound insulation effect, select the appropriate type of soundproof glass according to actual needs, such as hollow soundproof glass, laminated soundproof glass, etc., to ensure that the installation process of soundproof glass meets the requirements of the specifications.
Q: The sealing strip of the soundproof glass is aged, loose or damaged, resulting in a decrease in sealing performance, which in turn affects the sound insulation effect.
A: Prevent glass from breaking or cracking, and avoid excessive external impact on the soundproof glass, such as collision, knocking, etc. In the case of excessive temperature changes, appropriate protective measures should be taken, such as blocking sunlight and adjusting indoor temperature.
Q: Leakage or water ingress in the hollow layer or interlayer of the soundproof glass may be caused by poor sealing performance or failure to properly handle the edge gap during installation.
A: To deal with the problem of air leakage or water ingress, for soundproof glass with air leakage or water ingress, the sealing strip and edge gap treatment should be checked first. If the sealing strip is found to be aging or damaged, it should be replaced in time; if the edge gap is not properly handled, it should be re-processed. During the processing, it should be ensured that the sealing materials and processes used meet the specification requirements.
