Q:Is the cement board sound insulation effect is good, or gypsum board noise effect is good?
Our sound insulation board 425 (cement board composite, thickness 13mm) and Zhiwei noise board 410 (gypsum board compound, thickness 18mm) compared to the noise board 425 sound insulation better! The green sound insulation board 425 and the green wood safety board 458 (a gypsum board + a piece of glass magnesium plate composite, the thickness of 18mm) its Zhiwei noise board 458 higher sound insulation. In general, sound insulation is mainly high frequency and low frequency sound, different materials on both of them also play a different sound insulation (personal life point of view, but I think it should be right).
Q:How to repair crack in thin cement board?
go to mitre 10 or place makers and ask an assistant to show you a heat resistant cement that will glue cement board but in saying that gorilla glue is fairlie versatile however companies have spent years discovering the best adhesive for every purpose and I'm conident you will find just the right stuff
Q:Just laid cement board down w/ thinset over plywood. Do I screw in board right away or wait until set?
Screw or nail it right now! The idea of the thinset , so when it is secured is to fill any and all voids .. If you wait to long the thinset may have to be scraped up and you start anew. Any questions you can e mail me through my avatar and check my qualifications there. GL
Q:Do cement back boards (like Durock) contract/warp significantly if used for outdoor file floor?
Concrete backer boards are not waterproof and will wick water. In outdoor applications tile should be stuck to concrete, not a cellulose and concrete mixture. Even with a polymer modified thinset and grout you cannot be certain of a 100% waterproof exterior tile floor over backerboard. When the manufacturer tells you it's not recommended.....listen to them. Nothing worse than a failed tile floor.
Q:can i put ceramic tile on top of luan board in kithen and will it stick or would i have to use cement board or?
It ll stick for awhile but won t last. The total substrate thickness won t support tile. There will be to much deflection and the bond between the tile and luan will come loose from movement. You need a minimum of 1 1/4 total flooring to support tile. Most cases this is 3/4 sub floor and a 1/2 of a cement board or special plywood , properly installed. This come from both the TCA and ATC tile guide hand books. Any questions you can e mail me through my avatar and check my qualifications there. GL
Q:Why does noise do not mean sound absorption? How to use good sound insulation, sound absorption material to handle the hall? Ask the master enlighten me!
Second, to prevent the sound of vibration transmission: This plate requires a higher density of the unit surface, that is, the higher the density of the unit surface noise better, which is why the thick wall than the thin wall sound insulation better reason. Usually have fiber cement board and other products. Stone also has a good sound insulation, medium and thick steel plate has a good sound insulation effect.
Q:are you able to mountain board not only on dirt but also on surfaces like cement, for ex: a street?
you probably could
Q:How come Houses in Mexico are made of cement & bricks , but in USA are made of card board & wood?
Price!!! Im building a house in Mexico. Its the first house I have ever built so im learning a lot. But let me tell you from my experience. Building out of brick and cement is a lot more expensive and difficult than wood. If built right, a brick house can last for centuries. A brick house can have all the look of a wood house too. Which is what most american like and are used to. The cost though, is greater for the bricks. Brick houses are still build in the US, but not too often.
Q:Poured cement basement foundation history?
Yes (and as 2 other people already said) Concrete was in use long before then, in fact it is very much in use then, also if the walls are in real good shape that means they didn't pour cheap and let it cure long enough before moving on! Pour cheap basically means that when pouring concrete you mix several ingredients and if you cheapen the mix (more for non load bearing walls) or don't let it cure long enough (which final curing takes years) (see sources below for better explaining) Another way to find out if they re-poured 15 years ago is to look for support beams that look like they have been clamped onto!
Q:Will the decoration of the cement board with the kind of thin how many species
Cement on the 150 of the thinnest prefabricated panels
