Rock Wool Sheet
Products Description
Rock Wool Sheet, also known as mineral wool board , is a high-performance insulation material made from natural volcanic rocks and minerals. Basalt rock, an igneous rock formed from volcanic activity, serves as the primary raw material.recycled steel slag may be used, contributing to the sustainability of the material.The manufacturing of rock wool blanket&board involves advanced productive technology that harnesses the unique properties of basalt rock. The raw materials undergo high-temperature melting, and the molten material is then spun into fibers. These fibers are then compressed and formed into boards using a binder.

Products Features
Superior Thermal Insulation: Rock Wool Sheet provides outstanding thermal insulation, reducing heat transfer and ensuring energy efficiency in buildings.
Fire Resistance: The inorganic nature of the material makes it inherently fire-resistant, contributing to enhanced safety in construction projects.
Acoustic Insulation: Beyond thermal properties, RockWool Board excels in absorbing sound, making it a valuable solution for noise control in buildings.
Moisture Resistance: The hydrophobic nature of the material makes it resistant to moisture, preventing issues such as mold growth and maintaining its insulation properties.
Product Production Process:
The production process involves melting basalt rock at high temperatures, spinning it into fibers, and then forming these fibers into boards with the addition of a binder. The compression process ensures the development of Rock mineral Wool Boards with optimal density, thermal resistance, and structural strength.
Products Advantage
Energy Efficiency: Rock Wool Sheet significantly contributes to energy conservation by minimizing heat loss in buildings, thereby reducing the need for excessive heating or cooling.
Sustainability: The use of natural basalt rock and recycled materials aligns RockWool Board with sustainable construction practices, making it an environmentally friendly choice.
Versatility: The board's versatility extends to various applications, including insulation for walls, roofs, and floors in residential, commercial, and industrial buildings.
Products Usage
1.Exterior wall insulation
Rock Wool Sheet is an ideal building exterior wall insulation material. It can not only effectively reduce energy consumption, but also prevent the generation of condensation water and improve the water and temperature retention performance of the wall outside the body , It has become a very popular choice.
2. Indoor partition
The application of rockwool board in indoor partitions is also very common and widely used in general production. It can be used as various indoor partitions, wall panels, etc., and has good thermal insulation, noise reduction and fire prevention properties. In partitions, the use of rockwool boards can effectively improve the indoor living experience and environmental quality.
3.Suspended ceiling and ceiling
Rock wool boards can also be used in suspended ceilings and ceilings of buildings. The use of rockwool boards in these parts can effectively improve the thermal insulation performance and noise reduction performance of the building, creating a more comfortable and quiet living environment for people.
4. Curtain wall panels
Curtain wall is an advanced aspect that plays an important role in modern architecture. Building materials can also be used to make curtain wall panels. It has good thermal insulation performance and noise reduction performance, and can improve the thermal insulation performance and sound insulation effect of the curtain wall.
Products FAQ
Frequently Asked Questions
What is Rock Wool Sheet?
+
-
Rock wool board is a rigid stone wool insulation board designed for use as an exterior continuous insulation in residential to increase the performance of basement and exterior walls.
Why is ROCK WOOL so expensive?
+
-
The price of rock wool insulation is not directly dependent on natural resources but rather on the costs of processing. Higher labour wages and current fuel prices almost always increase the cost of this product. The higher the costs for the manufacturing company, the higher the purchase prices.
Is ROCK WOOL better than fiberglass?
-
Rock wool insulation is more durable than fiberglass Batt insulation. Fiberglass, unlike Rockwool, is neither water- nor fire-resistant and if exposed to water, it may become damaged,promote the growth of mold and mildew, and lose its insulating properties.
What is rock board used for?
-
Rock board is a premium multi-purpose board insulation to be used in walls, ceilings and floors for acoustic and thermal applications. These include insulating mechanical or utility rooms, or adding a barrier to noise and fire. These products are available in various densities to support different applications.
Why is ROC KWOOL so good?
+
-
Rock wool is more heat-resistant and fire-resistant than fibreglass. Rockwool can withstand temperatures up to 1000°C without melting or releasing toxic smoke, while fibreglass can melt at around 500°C.
What are the disadvantages of ROCK WOOL?
-
Rock wool is also a health hazard. Rockwool, like asbestos is made from rocks and minerals the fibers and dust thereof have proven to be extremely hazardous.
Is ROCKWOOL cheaper than fiberglass?
+
-
Rock wool is eco-friendly, while fiberglass is biodegradable. Fiberglass is less expensive, but rockwool could lower utility bill
How do you install rockwool board?
+
-
Clean surface and remove all debris from concrete walls. Mechanically fasten Comfortboard® 80 to the exterior concrete wall. Install 2x4 stud wall directly against Comfortboard® 80, leaving no air gaps or air space. Install Comfortbatt® R14/R15 thermal insulation between studs.
What happens if ROCKWOOL gets wet?
+
-
This moisture-resistant insulation does not wick water and since it is not made of any organic material, it does not promote mould growth. However, when there are leaks around the insulation, it will still get wet. It will also regain its previous performance once it fully dries out.
Is ROCKWOOL fireproof?
+
-
rock wool insulation is made from non-combustible fire-resistant stone wool that can withstand temperatures above 1,000°C1. This helps limit the spread of fire in a building. With minimal organic content, no significant toxic smoke is produced either.
