Rock Wool Strips
1. Product overview
Rock wool strips are made of natural basalt as the raw material, which is made of fibers after high-temperature melting. The direction of its main fiber layer is perpendicular to the surface. This unique structure gives it characteristics that are different from other rock wool products. It has four core properties: fire prevention, heat preservation, sound insulation, and weather resistance, and is widely used in high-standard safety protection scenarios in industrial and civil buildings.

3. Product Features
(1) Sound absorption/sound insulation: The open structure enables it to have excellent sound absorption/sound insulation performance, which can effectively absorb and block all kinds of noise, create a quiet and comfortable environment for the space, and significantly reduce both industrial noise and living noise.
(2) Fire resistance: As a non-combustible product, it will not burn or spread when exposed to open flames, which can effectively prevent the spread of fire and extend the fire protection time. For example, a 100mm thick rock wool strip can be used for 120 minutes, an 80mm thick strip can be used for 60 minutes, and a 50mm thick strip can be used for 30 minutes, building a solid defense line for the safety of life and property.
(3) Compressive strength: Made of corrugated board, the fibers are in an upright state during the assembly line process, allowing it to withstand high loads. At a compression rate of 5%, the pressure resistance is > 25Kpa; at a compression rate of 10%, the pressure resistance is > 40Kpa, which is suitable for application scenarios with high strength requirements.
(4) Moisture resistance: It has waterproof properties and can effectively release water vapor pressure to structures such as roofs, avoiding material performance degradation or structural damage due to water vapor accumulation.
(5) Chemical and biological properties: The pH value of rock wool strips is 7 or slightly alkaline, which meets the requirements of ASTM-C-795 and JIS-A-9504 standards. It is not conducive to the growth of mold, fungi, and bacteria, ensuring that the product will not deteriorate due to microbial growth during long-term use.
4. Product use
01 Industrial use: It is widely used in insulation and sound insulation of industrial facilities such as nuclear power plants, power plants, chemical plants, and refineries, effectively ensuring stable operation of equipment, reducing energy consumption, and reducing noise pollution.
02 Building use
03 External wall insulation: It is an ideal material for external wall insulation of buildings. It can effectively improve the thermal insulation performance of buildings, reduce energy consumption for heating in winter and cooling in summer, and improve the fire safety of buildings.
04 Curtain wall insulation: Provide reliable insulation and fire protection for curtain walls, meeting the dual needs of modern buildings for beauty and safety.
05 Other building parts: Used in building partitions, firewalls, fire doors and elevator shafts, giving full play to its advantages in fire protection and noise reduction, and improving the overall safety and comfort of the building.
06 Ship use: Used in cabins, onboard sanitary units, crew rest areas and other parts to achieve thermal insulation, fireproof partitions and sound insulation, providing a safe and comfortable environment for ship navigation.
07 Agricultural use: It can be used in factory-based planting facilities for vegetables, fruits and flowers to regulate the temperature in the greenhouse and create environmental conditions suitable for the growth of crops.
5. Product advantages
High cost performance: It has excellent fire protection, heat preservation, sound absorption, pressure resistance and moisture resistance. Compared with similar products, it can provide users with long-term and reliable use effects at a reasonable cost and reduce the overall use cost.
Convenient construction: various specifications and sizes are suitable for common construction and industrial installation requirements, and the weight is light, which is easy to carry and construct, which can effectively shorten the construction period and improve engineering efficiency.
Environmentally friendly and healthy: no substances harmful to the environment and human body are added during the production process. The product itself is non-toxic and pollution-free, meets environmental protection standards, and contributes to green buildings and sustainable development.
6. Customized service
Rock wool strip products of different densities, thicknesses and sizes can be customized according to customer's special needs. Whether it is the adaptation of special architectural shapes or the personalized insulation requirements of industrial equipment, we can provide professional customized solutions to meet your unique needs.
7. Construction precautions
(1) Storage requirements : Avoid open-air stacking and prevent moisture and rain.
(2) Installation specifications :
Quick-drying adhesive should be used to fix the sandwich panel during construction.
External wall insulation needs to be reinforced with alkali-resistant glass fiber mesh and anchor bolts.
(3) Safety protection: Wear a dust mask when cutting to reduce the inhalation of fiber dust
