Product Overview

1. The FCD ultra-fine inorganic fiber spray series is produced by spraying ultra-fine inorganic fiber wool and a water-based, specially formulated, environmentally friendly adhesive onto the base surface of a building using a complete set of specialized spraying equipment. After natural drying, it forms a new type of sprayed insulation, thermal insulation, noise-reduction, and sound-absorbing product that is airtight, seamless, structurally stable, and elastic.

2. After applying spray-applied insulation technology, a dense, carpet-like thermal-insulating and sound-absorbing layer is formed on the building surface, fundamentally addressing the shortcomings of traditional materials, such as poor air tightness, numerous joints, complex installation procedures, susceptibility to aging and deformation. Fiber-spray products effectively reduce energy loss, lower operating costs, and significantly enhance the overall thermal performance of buildings.

3. Spray application offers great design flexibility, enabling designers to realize their creative visions with ease. It is suitable for surfaces of any complex or irregular geometry and can be applied mechanically, delivering high efficiency. The coating can be directly sprayed onto materials such as wood, steel, concrete, gypsum board, and glass, eliminating the need for traditional support systems, suspension components, and reinforcing materials. This significantly reduces construction time and streamlines the installation process.

4. The ultra-fine inorganic fiber spray coating can be finished in a variety of colors and can also be combined with other decorative materials to enhance its aesthetic appeal and decorative effect.

Product Performance

I. Thermal Insulation Performance:

The FCD series products are high-performance insulation materials with exceptional thermal resistance.

Thermal conductivity: λ = 0.35 W/m·K

This value ensures that the spray-applied coating exhibits excellent thermal insulation performance. After spraying, the insulation layer forms a seamless, monolithic structure that effectively eliminates thermal bridges, thereby fundamentally addressing the common issues associated with traditional insulated profiles—such as numerous joints, easy detachment and deformation, and poor adhesion to the substrate—and significantly enhancing the thermal performance of building envelope systems.

II. Sound Absorption and Noise Reduction:

After being applied using a specialized spraying process, the fibers within FCD products interweave to form a three-dimensional, network-like structure that exhibits considerable strength and toughness. This structure significantly extends the propagation path and duration of sound waves within the material, thereby increasing the time available for the conversion of acoustic energy into mechanical energy through fiber vibration. As a result, the acoustic energy of sound waves encountering the fibrous spray coating is rapidly attenuated, endowing inorganic ultra-fine fiber spray-acoustic-absorbing products with excellent sound-absorption performance.

III. Fire Resistance:

The FCD ultra-fine series of inorganic fiber spray products are composed of natural inorganic materials. Testing has confirmed that they are non-combustible and do not support combustion, qualifying them as Class A1 non-combustible materials. They also meet the testing requirements specified in GB 8524-1997, “Classification Method for Fire Performance of Building Materials.” This outstanding characteristic effectively addresses the shortcomings of other materials.

IV. Safety and Environmental Protection:

FCD’s ultra-fine series of inorganic fiber spray coatings are Class A1 non-combustible materials. At high temperatures, they melt into a liquid state without decomposing, emitting no toxic gases or harmful substances, and are non-toxic and odorless. They comply with the national standard GB 18583-2001, “Limit for Harmful Substances in Adhesives Used in Interior Decoration and Renovation Materials,” as verified through testing. The product also exhibits excellent antibacterial and mildew-resistant properties, making it environmentally friendly and health-conscious.

V. Damping Sound Insulation:

The FCD product adheres to the steel plate surface, forming an integral, sealed sound-absorbing layer that effectively seals structural gaps, provides significant acoustic resistance, modifies the vibration modes of the steel plate, and substantially enhances its mid- and low-frequency sound insulation performance, thereby improving overall sound insulation. Experimental results demonstrate a highly significant noise-reduction effect.

VI. Adaptability of Complex Structures:

The FCD series of ultra-fine inorganic fiber spray coatings can be directly applied to any substrate, including steel structures and concrete, enabling highly efficient, mechanized, automated construction. They can be applied to surfaces with any degree of complexity, such as irregularly shaped structures, piping, suspended components, and densely packed areas.

Even in spaces that are difficult for construction personnel to access, spray application can be carried out with ease. This fully demonstrates the product’s moldability and its ability to provide complete, airtight encapsulation, significantly enhancing the thermal insulation and sound-absorbing performance of fiber spraying.

VII. Decorative Aspect:

The FCD series of ultra-fine inorganic fiber spray coatings can be applied directly to exposed surfaces. To ensure optimal acoustic performance, no additional materials need to be adhered to the coating surface; however, the surface can be finished in various colors to enhance its aesthetic appeal and decorative effect.
