Insulation Material For Thermal Insulation
1.Structure of Insulation Material For Thermal Insulation：
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 Insulation Material For Thermal Insulation：

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.

5.FAQ
We have organized several common questions for our clients，may 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,
②What’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.
③How 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: I have a low pitched roof so there isn't that much room up there hands and knees only.I have no eave ventilation but the ventilation is through the front and back of the house through triagle metal caps cut into the wood siding. I already have some R19 in the ceiling joists but was wondering would putting it in the rafters against the plywood holding the shingles also help insulate the living area of the house.
- No blowing in some insulation will help but putting insulation against the roof wont help. the attic area is supposed to breath to avoid condensation and overheating. The only thing you would put on the roof side would be to help cooling in summer since the shingles heat up the wood underneath and heats the attic, which then works down through the ceiling.
- Q: I have a converted loft which is really cold. The roof doesn't have any insulation, just a waterproof sheet, but i don't want to spend too much insulating it with the proper boards. If i use mineral wool and staple it across the roof trusses will it do a good job?
- Yes, be sure to leave an air space between the top of the insulation and the roof deck to allow for ventilation, and use a vapor barrier on the interior side of the insulation.
- Q: if you had snow and all the snow is off your roof and the house nex store has snow do we need insulation?
- That is very observant of you. Yes this could indicate that you are losing more heat than normal through your roof. Though, you do want to be careful in the placement of any new insulation, you will want to avoid any vents that are there for ventilation of heat and moisture in the summer and any recessed lighting fixtures as to not cause an overheating problem with them. This is a good investment and it will pay you back in heating and cooling cost for years to come.
- Q: Hi, my building is hot in temperature in summers, so I am finding ways to tackle the problem by placing some heat insulating materials against the sunlight on the roof of my building. I have found several possible solutions, but none of them close to perfect. 1. grass layer: hard to maintain2. heat-insulating brick: might be too heavy to carry them to the roof3. heat-insulating coating: would it be damaged if we step on them? Are there things like heat-insulating carpets that would be convenient to instal?
- Closed cell spray foam applied to the inside of your roof sheathing will work just fine. It needs to be installed by a specialty contractor. Good Luck
- Q: The distance between knee wall and attic ceiling is about 6 foot. Could I push a perforated pipe between the rafters?
- That is an option. And there aren't many options.Not much is going to slide easily behind the insulation. I'm thinking --------------------. You are undoubtedly going to snag on roof nails coming through the decking. I don't know if they would hold up but the cardboard tubes wrapping paper comes on might work if you tape 2 together. and flatten and tape the end you will be pushing in first. cut slots with utility knife. I think your idea would work if you can afford the pipe. That's a tough one. When we convert attics we line those cavities with a styrofoam insulation chute end to end until we reach open ventilation-you probably know that by now. Give it a try.
- Q: Can you put fiberglass insulation on the under side of roof tiles in the loft in the house?
- I would be concerned that this may cause moisture to form between the roofing and the insulation. They make a special foam panel that fit underneath the roofing in between the roof rafters. They allow air to flow from the eave to the roof's ridge.
- Q: i live in a tropical country and i need to insulate my roof to block off the heat from the sun...which insulation would best help me? aluminum foil with foam, real foil with foam or PE with foam? pls help...thank u so much!
- look into a product called "Snow Roof". You roll it on like paint and it will lower inside temp 10-20 degrees.
- Q: I am purchasing a mobile home with a shingled roof. The shingles need to be replaced (>15yrs old) and with the cost of heating going up each day I thought I would added some of that 2" thick rigid insulation. I would place this right on top of the existing roof and then place the firring strips for the metal roof right on top of the rigid insulation panels (which are 4x8'). By using 3" galvanized sheet rock screws I will get a good solid attachment. Then I will put the metal roofing on to the firring strips as normal. Does anyone see any downside to doing this? Has anyone tried this before?
- The only downside I see is your miscalculation about the length of the screws need. Lets see, 2 inches of insulation, 3/4 inches of furring, leaves you with a solid 1/4 inch of bite, and we all know that the first 1/4 inch of the screw is meant for piercing, not holding. So plan on 4 inch screws, because you still need to penetrate the old roof and bite the structure. Don't forget to plan your drip edge which now will have 2+ inches of roof thickness to carry the rain water over into your gutter.
- Q: Best roofing insulation to keep warm in the winter?
- Aluminum is a good resister to thermal flow, but its primary characteristic is to stop the transfer of air. A solid barrier of aluminum will stop air movement, and will reflect heat back. A drawback is that it must be installed in a way so that no air can move through any cracks. Blown in fiberglass is your best bet. Trapped air is what insulates a space. Cellulose settles with gravity after a period of time, the fiberglass does not settle, traps more air, and can have a resistance value of up to 33. A well-insulated attic will keep you warm in winter, and keep the hot attic air from infiltrating your home in summer.
- Q: i have roof insulation but if i add more to the required depth the bottom layer will get compressed. Will it still insulate?
- Compressed insulation is LESS effective than uncompressed insulation. It will still insulate more than not having it. If you are adding enough to actually compress the bottom layer, you have probably passed the point where additional insulation actually helps.
