Rock Wool Board For Thermal Insulation

1.Structure of Rock Wool Board 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 Rock Wool Board For Thermal Insulation


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:Attic Roof Insulation?
Such an interesting question when you sit down to answer it. First off, if there are any vents to the exterior, its not likely that you will want any additional heat to enter the space, as it will flow out of the vents to the outside and cost far more money than heat that is lost by thermal transfer, through the doors, windows and insulated walls and ceilings. So, any increase in the source of heat would mean closing the system to outside air vents like the fan and the soffit vents. If you want to heat the space, you'll need to insulate the roof by adding fiberglass batting to the space between the rafters and then drywall or panel depending on local building code and your preferences. Then you'll need an avenue for heat to reach the attic which can be as simple as cutting a couple of floor grates through to the heated space below, but you'll want cold air return ducting to send the cold air that is displaced by the heated air back down to the furnace. Then you'll need to seal the gable fan and insulate, perhaps with a box you can remove in the spring and replace in the fall. Now that the attic is integrated in the HVAC system, you no longer need the soffit vents. If you don't have a forced air system, there is less concern about the cold air return, as your heat source would be in the room or you can just use floor grates on opposite ends of the room for both the warm air and cold air exchange. Place one near the heat source below and one well away from it.
Q:Can I tear out all of the blow in insulation in the roof?
Don't remove the insulation, unless it has mold in it too. Locate the source(s) of your mold problem inside your building... a high rate of interior bulk moisture, and eliminate that. Then make sure the bathrooms have exhaust fans that are wired-in with the light switch (so whenever someone turns the light on, the fan comes on too), and that the fans are vented out of your attic (otherwise you'll have mold inside your attic). Also, make sure the kitchen exhaust fans vent outside (and the clothes dryers too).
Q:Construction question: how much sand can i substitute for insulation in home roof? i have back end loader?
first sand is very heavy and will probably exceed the loading on the roof and walls the extra reinforcing you would need to make the house SAFE would far outway any savings
Q:Can you insulate an attic in a house with a metal roof? (sweating)?
Hi, GA. On my second coffee here, so bear with me if a little fuzzy. Trying to envision what you're looking at, first thing I hear is 2x4 roof framing, not say the 2x6 or 2x8 rafters I would expect. A 2x4 structure and metal roof is a light build more suitable for a shed or outbuilding than a home. Wouldn't tolerate much additional weight, like from plywood. Next thing, which I don't hear, is whether there's moisture on the attic's "floor", where you're standing. I'm thinking the moisture you're noting is above you, on the undersurface of the roofing, and on the rafters. Finally, while some condensation on the underside makes sense, it would also seem quite possible that there are a number of small leaks through the roof. My goals would be to first ensure there are no leaks through the roof surface, then to ensure the attic indeed has enough venting, then to both reduce air from the lower living level bleeding through up to the attic space (also good to reduce convective heat loss), then to insulate the attic floor to reduce radiant heat loss from below and warming of the attic air, pretty much in that order. The prize is a leak-free roof over a cold attic space.
Q:Re-roof + gutter + insulation?
I am a roof plumber in melbourne I think this is a reasonable price. Materials will cost approx 8000-10000 grand 3300 for asbestos removal and the rest for labour. The best advice is plenty of quotes and keep them to their quotes. If you can get a roll of metal direct from bluescope you can get a company like apex roofing to roll it for you but it is alot of mucking around to save a little bit
Q:where can i find and compare prices on roofing and insulation materials?
You could call ABC supply or Norandex Reynolds, they are the biggest distributors I know of. They may have some resources for you.
Q:Interior roof insulation.?
Why would you want to waste money heating the attic? There are several reasons to put the insulation directly above the living space. Increases the life of your roof, prevents ice damming, saves money, helps avoid moisture issues in the attic and roof sheathing. Is that enough?
Q:Whats a good way to insulate water pipes on our roof?
Contact a local remodeling contractor and install the new piping system properly. Even a system under a foundation can be repaired, but it is not cheap to do it.
Q:why do icesicles form on the edge of my roof in the winter when my insulation value in my attic is at the...?
Anytime snow melts from a roof due to lost heat from the interior, or sun shining on the roof, but air is below freezing, icecycles will form. The real danger here is ice cycles that can fall when thawing and kill in extreme cases, AND ice dams can form forcing ice back up under shingles damaging roof. That is why it is often a good idea to install heat tape under the edge of roofs in areas that are prone to heavy freezes and snow.
Q:What thickness of rigid insulation is used on flat roofs?
It depends on what R factor is called for , usually 1 & 1/2 inch on roof 2 &1/2 on walls ( usually statdard)
