Product details

The product is elastic, light weighted and could be rolled up and folded. Its bulk density 60kg/m3-120kg/m3, thickness 30mm-100mm, Width 1000mm and length 1000mm-5000mm.


Simplex felt: with fine heat insulation property and sound absorption effect it is applicable to big sized pipelines, constructed wall and roof.

Fiber glass cloth sewed felt: it is applicable to big-span industrial facilities and building structures. It is breaking-resistant and facilitates construction. It also has dust-proof function when being used on constructed wall.

Aluminum foil felt: It is especially suited for circular pipelines, small equipment and pipelines of air conditioning systems. It often used for heat preservation of walls of buildings with light steel structure as it facilitates the construction. It has better functions of water-proof, dust-prof, dust-proof and heat insulation and could reduce liquid drop along pipelines.

Metal mesh sewed felt: it is suitable for conditions with great shake and high temperature. The product is often recommended to be used for heat insulation material on boilers, ships, valves and large-sized irregular pipes.


Rock wool blankets

Rock wool felt is a coil material to meet the needs of large-area laying. In addition to maintaining the characteristics of thermal insulation, it also has excellent shock absorption and sound absorption characteristics, especially for low and medium frequency and various vibration and noise.

Good absorption effect is beneficial to reduce noise pollution and improve working environment. This material can be arbitrarily cut according to the needs during construction. It is mainly used in building interiors, noise reduction systems, vehicles, refrigeration equipment, household appliances for shock absorption, sound absorption and noise reduction. The effect is very satisfactory.



Insulation performance: good thermal insulation performance is the basic characteristics of rock wool felt products. Their thermal conductivity is usually between 0.03 and 0.047 W/(m·K) under normal temperature conditions (about 25 ° C).

Combustion performance: The burning properties of rock wool felts depend on the amount of flammable binder. Rockwool felt itself is an inorganic silicate fiber, non-flammable.

Sound insulation: Rockwool felt products have excellent sound insulation and sound absorption properties. The sound absorption mechanism is porous structure of rock wool, when sound waves pass, friction is generated by the action of the flow resistance, so that a part of the acoustic energy is absorbed by the fiber, blocking the transmission of sound waves.


Main functions

Rockwool felt products use high quality basalt slag wool as raw material, have good non-combustibility, melting point above 1000 °C, particularly effective in heat insulation, fire reduction, or absorption of noise. Applicable to the insulation, heat insulation, sound insulation and silence of large pipelines, vessels, storage tanks, boilers and conveying pipelines.


Where can rock wool blanket be used?

 It is applied to steel structure roof, external retaining wall, indoor partition wall, sound absorbing ceiling, floating sandwich floor and other fireproof, heat preservation and energy saving, sound absorption and noise reduction, anti-condensation condensation. Low-density

rock wool felts are especially suitable for filling in the middle of steel structural frames, with good properties such as reduced heat transfer and sound absorption.

Fiberglass cloth rock wool blanket is suitable for large-span industrial equipment and building structures, resistant to breakage and easy to construct, used in building walls is to proof dust.

Aluminum foil felt is especially suitable for original pipelines, small equipment and air conditioning system pipelines. It is often used for wall insulation of light steel structures and construction.

Metal mesh sewing felt is suitable for vibration and high temperature environments. This product is recommended for boilers, boats, valves and large diameter irregular pipes
