Product Description:

Glasswool blankets

1 Introduction

The glass woll blanket is applied for large laying area.Besides the character of thermal insurance, it also has the performances of shock absorption and acoustical isolation, especially for middle or low frequency sound. It can also cancel the noise and improve working environment. The glass wool blanket with aluminium foil surface has good capability of heat radiation protection.

2. Glass wool Blanket Specification

The glass wool blanket is applied for large laying area. Besides the charater of thermal insurance, it can also has the performances of shock absorption and acoustical isolation, especially for middle frequency sound. It also can cancel the noise and improve working environment.

3. Application

It is mainly used for the partition wall in the high-grade building, such as ceiling, air conduit and inner wall for thermal insurance, machine shops for noise absorption and metal ceiling for control of moisture.High density glass wool blanket with laminated facing can be used for air conditioning duct system.

4. Image and Package

Normal packing: each roll is wrapped with vacuum plastic bag and then in PE woven bag. Special required package like PE BAG and PE SHRINGED BAG can be made with additional charge.

Q:Can Kunnai glass wool board and sound absorption blankets be used to maintain sound insulation in hotel floor? Can it decrease half of the noise? How to install?
Pour concrete with the thickness of 4-6 cm to the shock absorption pad. The floor treatment is mainly for solid conduction, and the surroundings also need to be isolated by shock pad. Shock absorption pad and concrete floor can ensure that the newly-poured floor is not hard-wired with the original building.
Q:Does glass wool belong to the asbestos insulation material?
No, it isn't
Q:The glass wool board of Kunnai Building Materials Corporation have different densities. Are there any differences?
Of course there are differences on attrition rate, and this is the same as rock wool. This will affect the schedule, especially will add construction difficulty. They are all inorganic materials, but the thermal insulation perfoamance is poor. I have accepted such a project in which the boards are of different density and there are big differences on their thermal insulation and fireproof performance. And I will not accept such project any more.
Q:If the glass wool is used for thermal insulation outside seamless steel tube, should the pipe be rust-proof and sprayed paint?
Rust-proof treatment must be done. Without special requirements, you can use epoxy rustproof paint for basic protection. For high demands, you should use zinc anti-corrosion paint.
Q:Why use reflective paper for pipeline package? Such as the caliduct in home is wrapped with a layer of reflective paper outside a layer of glass wool.
That 's not called reflective paper but aluminum foil, which is used to insulate heat. And pipes buried in the ground is also wrapped with this for heat insulation and errosion prevention.
Q:To reach better sound absorption effect, which should be filled in the keel, glass wool felt / board or polyester fiber cotton felt / board ?
Glass wool board Glass wool board is mainly used for sound insulation. Glass wool felt is mainly used for thermal insulation, and polyester fiber cotton felt is mainly for thermal insulation and sound absorption.
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:Is the glass wool used in curtain wall the thermal insulation wool?
No,it isn't.
Q:There is an engineering air-condition air duct which uses aluminum foil glass wool for heat conservation, supervor require that it should be added a protective layer made by glass fiber cloth. according to peremptory norms,
Aluminum foil layer itself is a protective layer, which has no need to be increased more protective layers, is using glass cloth for heat conservation layer, you can buy glass fiber cloth without aluminum foil protective layer. However, the protective layer of aluminum foil is really easy to damage, but its impact on air duct is not larger than water pipe, which is acceptable.
Q:Which kind of thermal insulation glass wool is the best?
Insulated wool is good. Rock wool: It is also known as rock cotton, which belongs to mineral wool. It is a fluffy, short and fine fiber made up raw materials like natural rocks and minerals. Rock wool, whose main raw material are natural rocks like basalt, gabbro, dolomite, iron ore, bauxite and more, is an inorganic fiber made by melting at high temperatures and fibering. Rock wool can serve as the insulation material with ablation resistance and high temperature resistance, the sound-absorbing material and insulation material of buildings and equipment, and the reinforcing material of cement product and rubber for sustituting natural asbestos, and high temperature sealing material, high-temperature filtering material and high-temperature catalyst carrier. 1. Insulation properties: Good thermal insulation is the basic property of rock wool and mineral cotton products. 2. Combustion performance. 3. Sound insulation performance: Rock wool and mineral cotton products have excellent sound insulation and sound absorption performance.
