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
Scaffolding from the erection of the main points on the scaffolding, cantilevered scaffolding and climbing three. High-level general use of floor and cantilever set of set enough to set the dumplings rush to set off the boat to Long. If the number of layers to more than 30F, and the structure can be relatively simple climbing scaffolding, climbing the advantage of the higher the height of the higher relative to the cost of picking. I am a professional scaffolding company, do not understand can ask me. I hope I can help you.
Q:What is the difference between an extruded board and an XPS extruded board?
1. Civilized construction program 2. Safe construction program 3. Template construction program 4. Scaffolding construction program 5. Sambo four construction program 6. Temporary electricity construction program 7. High operating construction program 8. Tower crane construction plan 9. Multi-tower operation anti-collision construction program 10. Emergency emergency plans 11. Winter rainy season construction program 12. Significant hazard assessment measures 13. Construction organization design 14. Building energy conservation program 15. Basket construction program 16. Tower crane hoisting program
Q:What is the difference between extruded polystyrene board and XPS insulation board?
Brothers asked, what is the price of extruded board in 2008 to do a report need to trouble to tell the next thank you
Q:I set up in October 2008, the production of XPS board - that is, with the extinction of polystyrene foam plastic plate, is an energy-saving environmental protection materials.
Think of the safety data directory to compare the trouble to compare JGJ59-2011 check the information bar
Q:Roof insulation layer is extruded polystyrene foam plate how set the amount of set
A type is generally used for pool or wear interior wall, B type for wearing structure (building) building facades Type I seals are suitable for general waterproofing requirements and Type II is suitable for tighter watertight requirements Applicable temperature range: -20 ° C ~ +80 ° C When the wall and pump or booster equipment into the inlet and outlet pipes, it is appropriate to set up a flexible connection at the connection I remember that we are usually the construction of the pipe through the casing into the pool, and then sealed with oil linen casing
Q:The traditional ceramic insulation board, the existing thermal insulation coating in addition to the process and the construction period there are similarities and differences there are differences?
Because the middle of the lap will lead to fasteners, fasteners can not withstand such a large force, and the top can withstand
Q:Steel structure rock wool sandwich wall panel what the amount of this set
The key indicator of good or bad weight is the weight, that is, the weight per cubic meter. Big enough.
Q:Extruded Polystyrene Board, Polystyrene Foam Board and Expanded Polystyrene Board
It is a white solid with a fine closed-cell structure which is heated and preformed in a mold by heating before it is made of a volatile liquid blowing agent.
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
