Product Description:

1. MPET Two-Layer Fire Retardent Bubble Foam Insulation Description:

Reflective insulation material consists of one or two layers bubble  or foam that are sandwiched between layers of 99.9% pure aluminum radiant barrier foil . This style can be used in a variety of applications because of its thin, lightweight properties. The bubble layers creates Maximum R value and Vapor barrier , the reflective foil on both sides allow it to reflect 97% of radiant heat away from a structure on the outside and back into a structure from the insides. This is why it works effectively in both hot and cold climates

Q:What is the heat conductivity coefficient of glass wool ?
Glass wool is a kind of spongiform fibre with silicate mineral which can form glass as main material and certain clinker as auxiliary material through fusion, fiber forming and a certain amount of organic binder. It belongs to inorganic glass fiber. Glass wool thermal conductivity is generally less than 0.1W / mK. If the test temperature is not high (150 ℃ or less), you can use transient plane source method. If the material itself is flocculence, you can measure without processing sample.
Q:Can glass wool be used in exterior wall for thermal insulation?
The tensile property of external wall thermal insulation materials is entirely determined by unit weight of thermal insulation materials and the mixture of binder with rock wool.
Q:Are thermal insulation glass wool boards hydrophobic?
It has poor performance in fireproofing and thermal insulation, and has a high heat conductivity coefficient. At present, it meet requirements of thermal insulation and energy saving policy for external walls. Glass wool is heavy itself, easy to slag. It can lead to serious pollution during construction and produce cancerogenic substance. It is highly absorbent, and easy to peel off. The operation life of which is short.
Q:Where are the differences between the glass wool board and glass wool blanket?
Glass wool board is metal face fireproof board, mainly are rock wool and glass silk wool, which is made by using color coated steel with advanced quality as plane material, continuous fiber cotton rock wool and glass wool as core material, high-density rigid foam polyurethane as rabbet fillings, foaming and solidifying through high pressure, automatic compacting cloth cotton and composing after super-long precise double-track control molding. Performance: ⑦ has good heat-insulating property. 2, has heat insulation and fire partition performance. 3, has excellent sound insulation and sound absorption properties. Glass wool felt is coiled material to meet the needs of large-scale laying. In addition to maintaining the characteristics of heat insulation, it also has very excellent shock absorption and sound absorption characteristics, and has good absorbing effects especially for the low-frequency and various noise and vibration, which helps to reduce noise pollution and improve the working environment. This kind of material can also be arbitrarily cut according to needs in the construction, mainly used for interior architecture, damping system, vehicle, refrigeration equipment adn damping, sound absorption, noise reduction of household appliances, whose effect is very good. Glass wool felt with aluminum foil on the surface also has strong thermal radiation resistance, which is wonderful lining material for high temperature workshops, control room, inner wall of machine room, compartment and flat top.
Q:What are the differences between the common and high temperature resistant glass wool boards?
The density of common and high temperature resist boards are different. Boards with higher density are more expensive. It is about 520 yuan per square meter. Nanjing Hairui Insulation Materials Co., Ltd.
Q:If rock wool board and glass wool are used in enclosed stone curtain walls, which one is better?
The meaning is actually same, but popularly it is called rock wool, while glass wool is adopted in actual use.
Q:Which is more expensive between glass wool and rock wool?
Glass wool board is more expensive than rock wool, but it is lighter in volume-weight than rock wool, which has the advantages that it will not cause itching of skin if exposed to skin, and its color is relatively bright with good thermal insulation and sound insulation.
Q:What are the advantages of Rock wool and import glass wool respectively?
Rock wool has a high burning point, and a good hydrophobic performance after adding hydrophobic agents. The diameter of import glass wool fiber is about 5 microns. The degradosome of which has no harm, besides veneering is relatively strong which can be 1.8 meters. And it provides additional support to heat bridge system.
Q:How to construct when apply rock wool board to glass curtain wall?
Basic interface treatment: The wall should be cleaned off grease and floating ash, etc. The loose and weathering part should be removed. If the protrusions on the surface of the wall is greater than 10mm, it should be removed. In order to make the adhesion of the base interface unified and homogeneous, the wall needs interface processing. An injection gun or brush can be used to evenly coat mortar to ensure that all the walls have been treated. Before interface processing, bricks and aerated concrete walls needs watering to wet it. When blocking scaffold eyes and abandoned holes, first clean the debris, dust, etc. and then wet it, and then use cement and mortar at a proportion of 1: 3 to fill the holes tightly. 2, Suspend vertical line and the controlling line: The method of laying lines should be determined according to the height of the building. Using the theodolite to look for the verticality making use of corners of doors and both sides of windows. Stretch low carbon steel wire to find the rules, and the horizonal line can be controled crossly based on the 500mm lines as the datum line which is higher than the building. According to vertical flux lines and insulation thickness, flip the control line on both sides of the angles of each horizonal spacing between purlins, and then draw the horizonal flux line as the mark. 3, Installation of rock wool boards: (Box bonding method and achorage of expanded anchor bolts)
Q:Does glass wool belong to the asbestos insulation material?
No, it isn't. Asbestos thermal insulation materials and glass wool insulation materials are two completely different products.The main function of asbestos products is heat insulation. General products are of it are asbestos cloth, asbestos ropes,asbestos packing, asbestos thermal insulation plates, asbestos velvet, sepiolite, asbestos mats, asbestos quilt,asbestos rubber sheet, PTFE products,metal spiral wound gasket, asbestos paper and asbestos lines added with steel wire.Amomg these, asbestos thermal insulation board can be thermal insulating. The main function of glass wool products is heat perservation. It has a certain heat resistance, but is not as good as asbestos thermal insulation material.Glass wool products are glass wool board, pipe and mat.
