Advantages of Polyurethane Sandwich Panels

1.Heat and sound insulation:The outer steel sheets can maintain the lastingness of the color of the building, and reduce the solar radiation and keep the appropriate indoor temperature. The high quality heat insulation materials are made with the adoption of polyurethane PU and (PIR) polyisocyanurate resin acid hydrogen containing no Chloro-fluoro-carbons.

2.A degree inflaming retarding:This system can effectively prevent the fire and prevent the fire from spreading during the cross construction and during the use of the boards

3.Environment protection:

By learning after the successful experience in environment protection constructions from companies home and abroad and through our scientific analysis, we objectively bear the idea of “low carbon designing, environmental building materials and energy-saving technology” in mind.

4.Super-low heat conductivity:

The lowest heat conducting coefficient of the heat insulation boards ensures that, under the condition that the thinnest heat insulation materials are used; the system can meet the energy-saving requirement and offer the strongest basic guarantee to meet the requirement of high standard heat insulation

5.Polyurethane roof panel are tightly connected blind nailing

6.Easily and quick installation

Q: Corrugated sandwich board is a kind of color steel plate? Thank you: Not sandwich plate refers to the middle folder with insulation layer, or other materials, composite sheet, strictly speaking, color steel corrugated board can be a color plate.

Q: Blockboard (sandwich panel) decoration cabinet right?: Now with the Malacca core blockboard, light and strong, flat without deformation, Malacca this wood is generally used to do musical instruments, you can not be good.

Q: Is the polyurethane sandwich panel and foam board flame retardant?: On the market, the polyurethane foam flame retardant grade B1, B2, B3 three grades. Because of the cost, sandwich board with the majority of polyurethane material is B3 level, a small amount of B2 level, there are a small amount of special requirements B1 level. B1 level for the 'flame'; B2 level for the 'combustible'; B3 level for the 'flammable'. B1 grade oxygen index requirements of more than 30%; B2 level requirements of more than 26%, 26% of the following collectively referred to as B3 level. You said the flame retardant, it should be self-extinguishing from the fire. B2, B1 from the heat certainly no problem. A little better B3 (oxygen index of about 25%) can also be self-extinguishing, but more than B2 self-extinguishing time more than a few seconds. General oxygen index of less than 24%, it is difficult to self-extinguishing from the fire, will always burn, the greater the greater the burning. The The Oxygen Index: The concentration of oxygen required to stabilize the combustion in the oxygen and nitrogen gas mixture under the specified shape of the foam, the specified source of fire and the size of the flame. - For example, the better the flame retardant properties of the foam, the higher the concentration of oxygen needed to ignite the foam, the higher the oxygen index of the bubble

Q: Rock wool sandwich board Yanmian generally what brand, quality Zeyang?: We are all with a small factory rock wool, we do not know the manufacturers, but this thing is too much pollution

Q: Can Caoyan rock wool sandwich panels be used as permanent construction timber?: Can not, just take a simple color coated board for a long time will be corrosive

Q: How about the use of colored steel sandwich panels on the balcony: Can you, inexpensive. Just when the rain is relatively large noise, lighting effect is not ideal If the conditions permit, then recommend the use of glass, 5 +5 plus plastic on the line. The price difference of about 30%. Life is longer than the color steel, low noise, good lighting.

Q: How is the ceiling of the residential sandwich panel under the roof?: Method is to use the form of flat ceiling, the top of the pipeline blocked in the ceiling, the top can be embedded in the downlight or built-in fluorescent lamp, so that the top of the decoration after the formation of two levels, will not produce a sense of depression. Shaped ceiling with a cloud-like wave or irregular arc, generally not more than one-third of the overall top area, more or less than this ratio, it is difficult to achieve good results.

Q: Rock wool sandwich panel price rock wool sandwich board how much money a square meter: This depends on the weight of rock wool, as well as color steel kind. If you need, we plant production. This answer is provided by Hebei Chengxin chemical building materials, if satisfied please adopt.

Q: How to calculate the force of the sandwich panel: Are generally estimated that we are doing this. Do not know how to calculate, but how many people we have to do the number of board

Q: Span 13 meters of the roof beam how to do the roof with 75mm foam sandwich board does not consider the wind load (indoor): We have a home here Jiangxi Baoyuan Caigang, they specializing in the production of sandwich panels, activities, color steel tiles, galvanized sheet, C steel, steel industry in the color of the very experienced, Jiangxi Baoyuan Caigang products sell well throughout the country , Won the majority of customers praise.
