- Ceramic Fiber Cloth
- CCEWOOL Ceramic Fiber Cloth is a woven fabric made from our high quality ceramic fiber yarn. It is strong, lightweight, flexible, and available in a wide variety of thicknesses, widths and densities. Ceramic cloth contain absolute amount of binder material which is normally burned at lower temperature and does not affect the insulation property.
- DJM Insulating brick
- Mullite insulating brick, using high pure mullite as raw material, is made by adding alumina powder according to different type and then sintering in high temperature. JM insulating brick is the new energy saving material for insulation.
- Ceramic fiber paper
- The product shows excellent thermal insulation properties and construction performance, suitable for use in deep processing (multi-layer composite, punching, etc.); and excellent resistance to molten infiltration, allowing itself to be used for casting washer separation in the construction and glass industries.
- Ceramic Fiber Tape
- Ceramic Fiber Tapes that are fabricated using high quality ceramic fiber yarn and are reinforced with fiberglass filament & ss wire.
- Ceramic fiber round rope
- Ceramic Fiber Rope is a length of fibers, twisted or braided together to improve strength for pulling & connecting and can also be called as fibril or filament. We provide round rope, square rope and twisted rope. Both kind has two type, glass filament reinforced and stainless stainless steel reinforced.
- Bio Soluble Fiber Blanket
- Bio Soluble fiber blanket is a body soluble fiber that utilises a unique spinning technology to create a special fiber with superior thermal and mechanical properties. This special fiber is made from a blend of calcium, silica and magnesium which give fiber the ability to support continuous temperatures up to 1260C.
- Ultrathin 6mm Ceramic fibre blanket
- CCEWOOL Untral-thin Ceramic Fibre Blanket is a new type of fire-resistant insulation materials in white and tidy size, with integrated fire resistance, heat separation and thermal insulation functions, containing no any binding agent. All CCEWOOL Ceramic Fibre Ultra-thin Blankets are made though spun fiber production, which is widely used in various sectors of refractory, insulation, thermal insulation field.
- Ceramic fiber board for wall-hung boilers and gas boiler
- The most outstanding characteristic of CCEWOOL Ceramic fiber board for fireplace and gas boiler is that it enjoys light weight, and at the same time it has high compressive strength./ Compared with the normal ceramic fiber boards of the same density, they are 20% harder; comparing to the ceramic boards of the same compressive strength, they are 20% lighter.

Characteristics of external wall insulation rock wool board
The external wall insulation rock wool board is specially designed and manufactured for the external thermal insulation system of the building. It is used for the thermal insulation or energy-saving reconstruction of concrete or brick external walls. Besides external wall insulation rock wool board can also be used as fire barrier to improve the fire protection function of building’s exterior wall.

The external wall insulation rock wool board is specially designed for exterior wall insulation. It is Grade A non-combustible fire proof insulation material. It has advantages of high compressive and tensile strength, low water and moisture absorption, good dimensional stability, no thermal expansion or shrinkage, aging resistance, etc. It is compatible with exterior wall systems and has very good performance in building thermal insulation, energy saving, fire proof etc. And can provide good protection to buildings under extreme climate condition.
The external wall insulation rock wool board has below characteristics.
1. High compressive strength, high tensile strength and long durability ensure long-term stability and reliability of product performance.
2. Rock wool does not burn, does not release heat and toxic fumes, and can effectively block flame spread when a fire occurs.
3. Excellent thermal insulation performance, which can increase the thermal resistance of the building envelope, reduce the energy consumption of heating and air conditioning, and save energy and reduce emissions.
4. No corrosion will be caused to carbon steel, aluminum (alloy), copper and other metal materials and various components in buildings.
5. Good sound absorption and noise reduction and elastic vibration reduction.
6. water repellent, aging resistance, long-term stable performance.
7. lightweight, can be cut and sawn, easy to process.
Above are the characteristics of external wall insulation rock wool board. Next issue we will introduce the application of external wall insulation rock wool board. Please stay tuned.
