Top 5 effective soundproofing materials

Privacy in life is always an issue that needs to be paid special attention and emphasized. To own a quiet space, separate from the outside environment is not difficult. Using soundproofing materials in construction will help you do it easily.

1. Gypsum board

Gypsum board is a type of soundproofing material, hard insulation and high aesthetics so it is often used in decoration. Drywall has a maximum sound insulation index of 70dB with an average volume of about 20kg/m2. The original gypsum is only white. When constructing, people will choose and paint on them different colors to harmonize with the most total space.

Gypsum board is the soundproofing material with high aesthetic

Gypsum board is mainly used for soundproofing in ceilings. They are supported by purlins with threaded rods, fixed and sturdy. Their advantages include:

• Room soundproofing index: 55 - 70dB.

• Durable gypsum with high impact resistance.

• The material is fire resistant for about 60-120 minutes.

• Light volume

• High aesthetic, easily process and bend

• Ensure health safety, do not contain cancer-causing amiang fibers and are especially environmentally friendly.

2. Glass cotton

This is a lightweight soundproofing material, consisting of many fiberglasses linked together. The main components of the material are Aluminum, calcium silicon and metal oxide. This is considered the leading material among the types of soundproofing materials, insulation.

Glass cotton is a soundproofing material used in low-cost buildings

The installation principle of this material is empty in the middle 2 layers of wall, then line the glass cotton layer in that position. Walls can be constructed with gypsum or other hard materials. Gaps are created to reduce the frequency of sound through layers of air, making them intransigent. The higher the density of glass cotton, the more soundproofing capacity exceeds theft. This density is usually reached from T12, T24, T32 with thicknesses of 25mm and 50mm.  

3. Precast concrete wall panels

Referring to building materials in the new industrial age, it is impossible if not mention precast concrete wall panel. The product has many outstanding advantages, can meet the strictest requirements in the construction process. The material is produced from sand and cement in a modern process with advanced technology, so it has a fairly light weight, only from 70 to 100kg / m3 (depending on size and thickness). This reduces gravity on the infrastructure and saves maximum construction costs.

This is a superior soundproofing material. Good insulation and water resistance of wall panels are superior to traditional materials. Not only that, prefabricated concrete wall panels are also fire resistant and highly durable and environmentally friendly.

Precast concrete wall panels are used for works that need fast construction progress such as factories, industrial parks,...

4. XPS foam

XPS foam is produced from PS plastic using special techniques. Through the process of expansion, molding pressed into plates, XPS foam has a sealed and foamy molecular structure. This soundproof material has a thickness of 15-18cm, a sheet form with a size of 60-120cm and is yellow or light blue. XPS has a light weight so it is convenient for designing and transporting to any constructions, saving cost.

XPS is suitable for building any cost-effective building

Because of foamy molecular structure, the XPS foam sheet has optimal sound insulation with a soundproofing index up to over 65%. And the insulation of the material is also extremely perfect with a low thermal conductivity index. Beside that, XPS foam has good compression resistance, closed molecular structure helps this material to be maximum water resistant. The application of soundproof foam is used for ceilings or walls of apartment buildings, …

5. Memory foam

Memory foam is an elastic plastic material with a design of many tiny holes located adjacent to each other. This structure is not only capable of absorbing noise, preventing low-frequency wavelengths, but also forms an external protective layer that prevents the corrosion of air extremely effectively. This type of soundproofing material is sheet form, soft and environmentally friendly and very easy to construct.

Memory foam has a sheet form, soft and environmentally friendly and easy to construct

However, memory foam has the disadvantage that they are relatively bulky and occupy a lot of area so they are rarely used in residential housing architecture. You will often come across images of this material in specialized rooms, which have special properties that need large soundproofing such as karaoke rooms or bars,...

Here are the top 5 soundproofing materials that are perfect for every building. Depending on the needs as well as the economic potential, customers can consider, choose the right product for your architecture!
