Acoustic insulation is the type of insulation used to reduce vibrations and noise with sound-absorbing materials. These absorbing materials help isolate noise sound by reflection and absorption with certain acoustic materials such as glass, mineral wool, fiber, stone wool, metal, and others.
Acoustic insulation is substantially used in commercial, industrial as well as residential projects for effective noise reduction. Acoustic insulation in this sector plays a vital role in reducing noise pollution, which affects the individual’s mental fitness and health.
Thus, individuals use acoustic insulation to reduce health effects while working on the floor in several sectors such as industrial, manufacturing, building and construction, entertainment, and others. Further acoustic insulation is widely used in construction applications in ceilings, floors, and walls for soundproofing.
The global acoustic insulations driven by rising building and construction sectors and increasing automotive sales have propelled the demand for the acoustic insulation market. Further rapid industrialization and urbanization, along with strict government rules and regulations towards noise pollution control by several governments, drive this market's growth.
Asia-Pacific is expected to be the largest segment with a market revenue share of 47.07% in the year 2019. The Asia-Pacific is anticipated to flourish the acoustic insulation market's growth due to the rapid urbanization and increase in construction activities in growing economies such as India and China.
Market Dynamics
Drivers
- Increasing demand for acoustic insulation in the industrial, automotive, and building & construction sector industries for facilitating noise absorption
- Strict government rules and regulations for noise control
Restraints
- The rising use of substitute products such as environment-friendly bio-based products over synthetic materials hampers the acoustic insulation market's growth.
- Improper disposal and recycling technique
The market is driven by increasing building and construction investments for the commercial, private and industrial sectors worldwide. Acoustic insulation in the building and construction sector reduces sound transmission through walls and ceilings and thermal insulation and sound absorption, which created a massive demand for the acoustic insulation market.
Rising government investments by developing and developing countries for the building and construction sector drive the growth of the acoustic insulation market.
For instance, investment in China in the buildings and construction sector reached around US$ 1.8 trillion in 2018, whereas, in the United States, investments in both residential and non-residential construction reached around US$ 1.4 trillion, increased at the rate of 3.8% between 2015 to 2018. It created a massive demand for the acoustic insulation market used for the new and retrofitting of the residential, commercial, and industrial buildings.
Some of the other factors influencing the growth of the market in the building and construction sector are building codes and regulations, construction of new buildings, population growth, energy costs, and sustainability.
Strict governmental standards to reduce noise pollution and improve living standards are among the main reasons driving the building and construction market for acoustic insulation. For instance, the Noise Pollution (Regulation and Control) Rules 2000 was adopted by the Indian government and the 1972 U.S.A. Noise Pollution and Abatement Act.
Besides, consumer demand for better noise, vibration, and harshness (NVH) levels and widespread competition between automotive manufacturers to include acoustic products will boost the automotive sector's demand.
Market Segmentation
Plastic foam is further classified into Polyurethane (PU), Polyethylene (PE), Polystyrene (PS), Polyisocyanurate (PIR), Phenolic Foam, and Others. The most frequently used insulation materials are urethane foam, rock wool, polystyrene, and slag wool. Among all, PU holds most of the market share in 2019, followed by PIR with 67.50% and 12.14%, respectively. PU is the fastest-growing segment during the forecast period among all other plastic foam from 2020 to 2027. The demand for heating, acoustic and cooling comfort has been increasing among the rising middle-class populations in developed and developing countries, which is expected to raise the demand for insulation.
The global polyurethane plastic foam acoustic insulation market was valued at US$ 7.091.90 million in 2019 to grow at a CAGR of 6.65% during the forecast period 2020 to 2027.
Polyurethane foam insulation materials are non-fibrous in nature, and therefore, personal protection equipment is not required during mounting.
They are commonly used in building and infrastructure. The polyurethane (PUR) is produced by making polymeric isocyanate react with a polyether polyol in the presence of catalysts and additives.
Polyurethane foams are the largest category of cellular polymeric materials. They find applications in a wide variety of industries as they are lightweight and economical.
Some flexible polyurethane foams are molded, especially for use in the automotive sector, mainly for car seats, while rigid foams are mainly used for acoustic insulation of buildings.
Polyurethane foam is about seven times more expensive than regular glass fiber insulation per unit. However, the polyurethane will provide about 2.5 the insulation value per unit of glass fibers. Therefore, walls can be thinner with savings in window and door frames, roofing, foundations, and structural members.
In September 2019, Demilec, Inc., a subsidiary of Huntsman Corporation and one of North America's manufacturers of open- and closed-cell spray polyurethane foam (SPF) insulation and coatings launched several spray foam insulation products for the Middle East market and the opening of its Spray Foam Technical Application and Training Center in Dubai. This will help in expanding the global footprint to serve customers in the Middle East better.
The polyurethane foam market in North America is growing at a steady rate. The United States was the second-largest end-user country of polyurethane foams in 2019.
The growing construction industry and the recovery of the automotive industry in North America are expected to enhance the demand for polyurethane foams. The United States alone produced around 10.88 million vehicles in 2019.
Similarly, Europe, especially Western Europe, is witnessing steady growth in the demand for polyurethane foams in various end-user industries. The Construction industry is growing at a steady rate across the region. France, Germany, the UK, Spain, and Italy were among the top 10 largest construction markets in Western Europe in 2018 and 2019. Similarly, the Automotive industry in Western Europe is growing at a rapid rate. Germany alone produced 4.66 million units of motor vehicles in 2019, while Spain produced 2.82 million units.
On the other hand, the APAC region's Polyurethane Foam market is growing faster than in other regions. China is the largest consumer and producer of polyurethane foams in the region. The major reason for the market's growth is the increasing demand from industries such as Construction and Automotive.
The APAC region's Construction industry has grown at a CAGR of more than 10% during the last five years. This growth is expected to gain pace during the forecast period. Similarly, countries such as China, Japan, India, and South Korea were among the top 10 producers of motor vehicles in 2019, and they are expected to maintain their leading positions during the forecast period.
Geographical Analysis
Asia-Pacific evolved as the most lucrative regional market for acoustic insulation market owing to the rising adoption of soundproofing materials in buildings, automotive, railways, and several other industries. The region accounted for 47.07% of the global acoustic insulation sales revenue in 2019.
The rapidly growing construction industry and the strengthening regulatory environment surrounding acoustic requirements in buildings are key factors leading to the growth of the acoustic insulation market in the region.
China has the world’s largest construction industry accounting for nearly 20% of the global construction output. Japan, India, Australia, and Indonesia are among the top 10 construction markets contributing significantly to the global industry.
Japan and China lead in the regional acoustic insulation market with high ratios of commercial and multi-story buildings. The use of soundproofing solutions has been very high in these countries over other Asian peers.
Asia-Pacific is growing at the fastest CAGR of 7.1% during the forecast period (2020-2027)
