Product Description:

Heating Insulation and Fire-proof Rock Wool Board

1.Structure of Heating Insulation and Fire-proof Rock Wool Board

Rock wool insulation refers to a type of insulation that is made from actual rocks and minerals. It also goes by the names of stone wool insulation, mineral wool insulation, or slag wool insulation. A wide range of products can be made from rock wool, due to its excellent ability to block sound and heat. This type of insulation is commonly used in building construction, industrial plants, and in automotive applications.


The Manufacturing Process

Melting / Forming into fibers /Continuous-filament process/Staple-fiber process/ Chopped fiber/ Rock wool / Protective coatings /Forming into shapes

2.Main Features of Heating Insulation and Fire-proof Rock Wool Board


Thermal Insulation

Fire Safety

Acoustic Control

No Corrosion

Environmental friendly

Moisture Resistance

Energy Conservation & Emissions Reduction

Different raw material: Our rock wool is mainly made by Basalt and other natural ores. The raw material for other so-called rock wool is mineral slag. Different raw material, different features.

Different corrosion resistance. Our rock wool have good corrosion resistance. non-corrosive for metal. But the mineral slag wool is different. In high humidity environment, CaS in mineral slag will have chemical reactions and produce corrosive when contact with metal.

Different working life. The working life for mineral slag is very short and Durability is very low because of higher CaO and MgO in slag. The efflorescence for mineral Slag is easy and also effect the working life. The

Different heat resisting. The heat resisting for rock wool(Basalt) is higher than mineral Slag wool. Our operating temperature can reach 800.But for Slag wool ,can not higher than 675.The features for our rock wool is totally superior to Slag wool.

We have organized several common questions for our clientsmay help you sincerely

①     What’s the mainly material for rock wool

Rock wool is called a mineral wool because it is made primarily from basalt, an igneous rock,

What’s the mainly type for rock wool

rock wool insulating products are available in loose-fill form and as batting. Batts, or blankets, are thick slabs of insulation that may have a kraft paper facing.

How you control the quality?

During the production of fiberglass insulation, material is sampled at a number of locations in the process to maintain quality.

Q:ROOF INSULATION how to add more insulation on the outside!!!?
You could build a pitched roof on top of the flat roof.
Q:loft conversion- how do i stick insulation foam to the inside of the roof?
These are sheets of foam cut to size, they use a piece or steel wire to hold the foam up its cut some what longer then the width of the bal so it bends forcing it to dig into the joist.
Q:Can anyone recommend a good roof insulation company in Phoenix AZ?
Blow in insulation is so easy and cost effective, do it yourself. Machines can be rented at Lowes, HD, etc where you buy the material.
Q:How best to insulate interior of attic roof?
The reason you do not put insulation directly on the underside of your roof is all about moisture and mold. You need an air gap between the roof and the insulation and allow it to breath. This prevents moisture from condensation that can cause big problems. You could install a radiant barrier that reflects the heat. Do a google search to learn more about it. You could install and attic fan to suck the hot air out in the summer. Most important is to make sure the insulation on the attic floor is the proper thickness.
Q:Flat roof replacement,is bitumen used as flashing? What type of insulation is best when replacing a flat roof?
We use kingspan insulation, marine grade plyboard , 3/4 inch, and yes you can use bitumen as flashing. I hope i am not being condescending, but the flashing is the bit that goes from the roof and a little way up the wall and is then "pointed" into the bricks, thus forming a water-proof barrier.
Q:Is it necessary to have attic roof insulation?
Its normal to have a insulated attic.. I once noticed a neighbor--that used a large exhaust fan..and his roof was bowed.. He also would use alot of firewood in his house.. I think that moisture somehow--damaged the attic area--/
Q:Metal roof condensation issue low budget? Spray-on insulation?
The problem might be resolved by venting the attic. You need to have an air exchange in the attic to prevent condensation.
Q:do i leave air gap in attic roof for insulation?
The best way to set up an attic is to put a vapor barrier under the rafters (before nailing on the gyproc), then put the insulation (fibreglas batts) between the rafters to full depth (10 or 12 inches). Soffit vents are installed under the eaves at the sides of the roof, and gable vents are placed near the peak of the roof at the ends. This allows for airflow resulting from convection, particularly important in the summer months to remove heat buildup in the attic. If the insulation is adequate, it will not only isolate this heat buildup from the inside of the house in summer, but will prevent heat loss to the attic in winter. (The airflow in winter will be minimal, but will remove any moisture/condensation that might collect otherwise.)
Q:Questions on roof heat tapes and insulation?
They are not a substantial fire hazard. They are far more likely to just stop working than to get overheated.
Q:do I have to blow insulation in the roof of my mobile home if I install foam insulation under a meatle roof?
Some mobiles have a vented attic and some don't. If your attic is vented, the foam on the roof won't help insulate inside the house. I've blown insulation into a mobile home attic before (vented attic), but some mobiles one can't (not vented attic). There are different variations of attic venting, dictating if you can blow in or not. I would add insulation anyway, if you can, mobiles usually skimp on attic insulation, even if they are "certified".
