 XPS boardTile backer board

XPS backer board


Choose a way to fix CMAX board according to the substrate to be fixed. Normally, using modified tile adhesive for solid concrete wall/floor and strengthened by mechanical fixings when necessary while only using mechanical fixings for wood and steel frames.

XPS tile backer board 


1. Dry areas: reinforce all joints between boards, floors and walls by 125px or 250px wide self-adhesive tape.

2. Wet areas: reinforce by suitable waterproof  tape.

XPS board


Waterproof strengthen:

1. Strengthening all joints between boards, floors, walls and mechanical fixings placements by suitable waterproof tape.

2. Strengthening joints between walls, outside corners and inside corners by special corners.

3. Sealing pipe holes with special waterproof tape.

4. Strengthening once again by waterproof glue, liquid tanking membrane, tanking membrane paint, etc. when necessary.


Coating of panels:

Should always be covered by ceramic tiles, mosaics or other equivalent non-fireproof materials after installation.

Q:Roofing the top of the extruded polystyrene insulation board generally how much weight ah?
The bar spacing is called 'step distance', 1.2 ~ 1..1.8m, no minimum spacing, maximum 1.8m. Pole spacing 1..1..1.55m, no minimum spacing, maximum 1.55m. See JGJ130 Haifa Fenzhuang Curcuma Gufeng Koufukai -2011 "Construction Construction Fastener Steel Scaffolding Safety Technical Specification" 'Structural Requirements'.
Q:Why extruded board (XPS board) is the best insulation board material
Should belong to the template and support system. Full scaffolding is generally used for single-storey building, hall and other high-rise, large building between the top of the building decoration. By the pole, cross bar, bracing, scissors and other components.
Q:What is the difference between an extruded board and an XPS extruded board?

Panasonic refrigerator with the world's leading vacuum insulation material Vacuuminsulationpanel (referred to as VIP) vacuum insulation board, is developed in recent years, a new type of highly efficient insulation material, which uses vacuum insulation principle, under vacuum conditions, the thermal conductivity is very low , Widely used in household appliances. The product to fill the gaps, is a leading international high-tech products. . VIP in the production and application process does not use ODS substances. . the insulation layer of the same thickness, you can save energy. . the same energy consumption, VIP can reduce the thickness of the insulation layer to reduce the volume of objects, increase storage space. . VIP design engineers can provide a variety of flexible options. . CFC consumption of ozone, destruction of the ecological environment, if the alternative blowing agent, its high thermal conductivity, reducing the thermal insulation properties of the foam, although the environmental protection, but need to consume more energy, and VIP is environmentally friendly And the dual advantages of energy saving. . VIP on environmental protection and national energy conservation has a great contribution. . VIP thermal conductivity is PU one-eighth, is the replacement of insulation materials. Vacuum insulation panel (VIP) technology industry has quickly formed a practical industry trends, and industry-class enterprises to adopt. Was rated as energy-saving refrigerator model products which is the use of VIP technology to achieve energy-saving purposes. (BCD-239DVC), Panasonic "energy saving king" refrigerator (NR-E461U), the new energy-saving "Golden Eagle" refrigerator (BCD-218E) Meiling "digital energy-saving Wang" refrigerator (BCD-239DVC) BCD-200A / HC, BCD-270A / HC and other six models (BCD-219U / C), the best energy-saving refrigerators, including BCD-180A / HC, BCD-200A / HC, BCD-270A / HC and other six models Wait.

That is, can be in the farthest bowel forging forging treadmill punch fist away from the pull up the most important things tower crane top of the car can move back and forth he moved to the farthest place to pull up the heaviest weight is slightly! The
Q:Sound insulation and polystyrene insulation board which sound insulation better?
But its assembly is more complex and is not conducive to high-level construction, safety performance Dingzao cut to cut the salt tax is also poor, if the assembly is very easy to accident, and susceptible to natural factors and reduce its safety, As more and more emphasis on the protection of green today, it is bound to be replaced by steel scaffolding fastener type steel scaffolding with easy processing, easy handling, versatility and other advantages, is currently the largest use of China, the most common use of a scaffolding, but this scaffolding security is equally poor, the construction efficiency Low, scaffolding maximum erection height of 33 meters, can not meet the development needs of high-rise building construction bowl button assembly disassembly is relatively simple, the assembly performance is also good, more in the United States, China seems to use is not very wide But personally think that the future bowl button scaffolding will certainly be popular, there are prospects aluminum scaffolding is mainly lightweight, corrosion-resistant But not a high degree of construction, can not be high-level construction the disc does not seem to use the fastener with the bowl button type, universal joint do not understand So, personally think that in China fastening scaffolding or the mainstream, bowl button-style prospects are good
