2 Rockwool Market Growth Drivers and Restraints
Green environmental protection trend drive: With the increasing global attention to environmental protection, the construction industry, as an important area of energy consumption, has a growing demand for energy-saving, emission reduction and low-carbon materials. Rock wool is internationally recognized as the main energy-saving material in the “fifth largest conventional energy” for its excellent fireproof and heat-insulating properties.
Using 1 ton of rock wool products for insulation in buildings can save at least 1 ton of oil each year, which is in line with the development trend of low carbon, energy saving and emission reduction. In addition, fire accidents caused by improper selection of external wall insulation materials occur frequently. As a non-combustible material, rock wool can effectively reduce the risk of fire and protect the safety of residents’ lives and property. Therefore, it has broad application prospects in the construction field, providing strong support for market growth.
Downstream market demand growth: Rock wool has a wide range of downstream applications, covering construction, industry, agriculture and other fields. In industrial fields, such as boilers, large equipment pipelines, etc., rock wool can be used to construct lightweight furnace walls, reduce heat loss, and improve energy efficiency. In the construction industry, with the popularization of the concept of green building, rock wool, as a Class A fireproof green building material, has been widely used in foreign countries, especially in the European construction market, and has formed a mature product standard and system certification system.
The per capita rock wool consumption in Northern Europe exceeds 20kg. Due to fire protection requirements in the United States, rock wool and slag wool account for 70% of building insulation materials. In Germany, almost all exterior wall insulation of buildings over 22 meters high uses rock wool. These data show that the demand for rock wool in the downstream market continues to grow, which has strongly promoted the development of the market.
Development of online sales channels: The advent of the Internet era has prompted continuous innovation in sales models, and the online marketing of rock wool has shown great advantages in the fierce market competition. Compared with traditional marketing channels, online sales have obvious advantages in sales costs, channel management costs, information flow and capital flow.
It simplifies the complex channel structure in traditional marketing, integrates sales, pre-sales and after-sales services, and product and customer information inquiries, and provides consumers with a more convenient shopping experience. With the continuous advancement of information technology, the development speed of online sales channels is accelerating, and its advantages over traditional sales channels are becoming more and more prominent, further promoting the sales growth of the rock wool market.
Fluctuation of raw material prices: The main raw materials of rock wool include basalt, dolomite and recycled slag, and the cost of raw materials accounts for a large proportion of the production cost. Affected by the COVID-19 epidemic, the global economy has suffered a shock, and governments have implemented blockades and restrictions, resulting in restrictions on factory production operations, and the production and supply of raw material suppliers have also been affected.
Some quarries have closed or reduced production efficiency, and with the resumption of work and production, market demand has rebounded, and raw material prices have fluctuated. This price fluctuation directly affects the profits of rock wool products and the income of enterprises, and has brought certain pressure to the stable development of the market.
Problems with the product itself: Rock wool has some performance and environmental protection problems. From the perspective of durability, although rock wool is more durable, it also makes it difficult to biodegrade after it is discarded, and it will exist in the environment for a long time, bringing certain environmental burdens. Its fibers and dust are harmful to human health. Although the threat level is lower than asbestos, it still affects human health.
In agricultural applications, the high pH value of rock wool requires adjustment of the nutrient solution, and its low buffering capacity for water and nutrients limits the growth environment of plant roots. These problems have affected the application of rock wool in some fields and the further expansion of the market to a certain extent.
Industry competition is fierce and there are many substitutes: The global rock wool market is highly competitive. Many well-known companies such as Rockwool, Knauf Insulation, Saint-Gobain, etc. have occupied a large market share with advanced technology and strong brand advantages, and new entrants face high competitive pressure. In addition, rock wool faces the challenge of multiple substitutes in the field of thermal insulation.
For example, glass wool has lower bulk density, less slag ball content, lower thermal conductivity, longer service life and higher fiber toughness; the thermal insulation effect of foam plastics is also better than rock wool, and its special structure gives it excellent thermal insulation performance. The existence of these substitutes has formed a certain restriction on the growth of the rock wool market.
3 Technological Innovations in the Rockwool Market
Product performance optimization and innovation: Many companies are committed to improving the performance of rock wool products. For example, Paroc Group (Owens Corning) launched a new sustainable development goal to develop new products with low carbon dioxide emissions. Its new carbon-neutral product line Paroc Natura not only has the fireproof, moisture-proof and durable characteristics of traditional rock wool, but also effectively reduces carbon dioxide emissions in the construction industry. Some companies focus on improving the thermal insulation, sound insulation and fireproof properties of rock wool. By improving the production process and raw material formula, the product performs better in these aspects to meet the higher requirements of different industries for rock wool.
Production technology improvement and innovation: The improvement of production technology is also an important direction of technological innovation in the rock wool industry. Some companies use advanced production equipment and processes to improve production efficiency and product quality. For example, some companies use advanced centrifugal technology to centrifuge raw materials into fibers at high speed, making the fiber quality of the product more uniform and the performance more stable. There are also companies that use digital control of the production process to achieve precision and automation of production, which not only improves production efficiency, but also reduces labor costs.
Corporate mergers and acquisitions integrate resources: Corporate mergers and acquisitions occur frequently in the rock wool market, aiming to integrate resources, expand the market and enhance competitiveness. In 2019, Knauf completed the acquisition of USG Corporation. This acquisition integrated the businesses and product portfolios of both parties, making Knauf a leader in the global building materials industry, further expanding its business scale in the North American market and increasing its market share.
Saint-Gobain reached an acquisition agreement with Continental Building Products. Through the acquisition, Saint-Gobain broadened its asset portfolio, enhanced its ability to provide innovative solutions to a wider range of customers, and improved its position in the North American gypsum board market, achieving geographical complementarity and product diversification.
