Product Description:

Owing to glass wool'good performances,e.g.,thin and long inner fiber,low thermal conductivity,it can stop air flowing and heat transforming,Meanwhile,it can quickly reduce the transportation of sound to make effects of insulation and sound-absorption.Centrifugal glass wool is divided into glass wool boards and blanket .It was the best material used for the insulation and sound absorption of steel structures.It mainly includes bare blanket with foil -clad covered.They are widely used in industrial plants,warehouses,public facilities,exhibition centers,shopping centers,cold stores and a variety of indoor playgrounds,sports grounds and other buildings.

Glass wool board is processed by putting the thermosetting builder into the glass wool,buy pressing and heating,and then,by curing.they are widely used for insulation,ventilation and the adjustment of air-conditioner in commercial industry and residential constructions.Meanwhile,they have the effect of energy-saving insulating.sound-controlling and improving the indoor air quality.

Q:What are the construction methods of glass wool board used in external wall?
The phenomenon of moisture condensation in glass wool should be prevented.moisture condensation in glass wool, a layer of vapour barrier should be attached to the surface of the glass wool.A layer of glass wool should be fixed on the wall by insulation supporting pin prevent the glass wool from falling and thermal insulation properties from reducing.
Q:What is the function of glass wool foil?
Glass is made by melting such raw materials as quartz sand, limestone, dolomite and other natural ore with some chemical materials like pure alkali and sodium borate. In the molten state, the glass is thrown into fine fibers in the shape of floc by the with external force. These fibres vertically interwine and show many small gaps. These gaps can be regarded as air void. Thus, glass wool can be regarded as porous materials and it is of good insulation and sound absorption performance.
Q:Is glass wool felt the mineral wool felt?
No.
Q:Are thermal insulation glass wool boards hydrophobic?
Do not believe any hydrophobic agents. Products being processed with silicone hydrophobic agents have a short hydrophobic phase, and the performan of which has no guarantee. The thermal insulation performance of A-level glass wool products are poor which may lead to inferior wallboard engineerings.
Q:How does the glazed wall in the living room fixed? The top surface of the glazed wall is mineral wool board.
Slot on the ground, and embed stainless steel (for beauty) U-shaped groove (ensure its safety and base fixing) with a size of 2-3mm, and put a shockproof bar at the bottom of it, and then insert the glazed wall (be sure to use tempered one) with glass cement filling the surroundings; and as for the top fixation, the most important thing is to ensure that it will not shake.
Q:How much is the unit weight of thermal insulation glass wool boards at least? How much is the unit weight of sound absorption glass panels?
They are from twenty to less than eighty.
Q:Is the glass wool used in curtain wall the thermal insulation wool?
No,it isn't.
Q:Which has better effect of sound absorption, glass wool or rock wool?
I will choose glass wool as it is easy to install due to its low density.
Q:Can glass wool be used for external wall insulation?
Yes, of course, but the thermal insulation effect of glass wool is generally not very good, suggest using XPS board or EPS boards.
Q:How to use glass wool for filtering?
you can use buchner funnel or filter paper, specific question needs precious analysis, it mainly depends on the filter state, if solid particles are large, you can directly use ordinary funnel but not filter paper, when solid particles are small, you can use filter paper.
