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:Is the cement board a cement pressure plate? What's the difference?
Is a kind, just a different name
Q:What is the cement pressure plate, what is the use of it?
Is a new generation of "green" building materials, in the excellent moisture, fire performance based on the unique environmental protection features. It is based on siliceous and calcareous materials as the main substrate, with cellulose fiber reinforced materials, mixed with other auxiliary materials, through the copy forming, high pressure curing the formation of a new type of building materials.
Q:Laying hydraulic water stop cement?
Yes and no. The good thing is that is dries really fast and you can use a wire brush to help clean the surrounding areas after filling the crack or hole. Just don't let the mix get to dry before using the wire brush. Also, when doing this, use the coldest water and it will cure more slower.
Q:Backerboard, Cement Board, Blue Board. Call it whatever. Anyone found an easy way to cut it?
If you can handle a little dust, they make a cement board blade for a 7 circular saw. It has about 24 big teeth on it and it slices right though. It will give you a nice clean edge. But there is the dust factor so I always set up outside and use a dust mask. I've used the blade for about 3 years and it is still sharp.
Q:What are the densities of tiles and cement
The combination of lignocellulosic and Portland cement produces a non-toxic building material plate that does not contain any volatile toxic substances such as asbestos and formaldehyde. Wood fiber cement board will not produce any harmful substances, excellent environmental performance. Wooden cement board contains 71% Portland cement, 19% mineralized wood fiber, 9% moisture and 1% binder. Wood fiber cement board conforms to ASTM E 136 non-flammable building materials standard, excellent structural performance. Soaked in water is not layered, stable uniformity. Wooden cement board can be cut, planing, grinding, drilling, threading, and can be fixed with nails or screws.
Q:How to choose their own materials made of steel structure compartment?
There are many kinds of steel loft production materials, such as I-beam, H-beam, channel, square tube and so on. It is important that the owners must see is not the national standard.Now a lot of construction teams are using some non-standard products, non-standard steel has many defects, thickness, shear, tensile are not up to standard, will leave a lot of hidden dangers.
Q:Can I cut a relief in Hardibacker cement board?
You can use a rasp or a router with a carbide cutter. best done outside while waring a dust mask.
Q:For what would you use 4'X8' sheets of 5/32 thick cement board impregnated with fibers?
Not for tile like every one is suggesting. That is way to thin. That size isn t even a 1/4 thick. That product , what every is is , isn t for tiling, thats for sure. Maybe a wall board for insulating of some type? Even thats a guess. GL
Q:Are moisture and mold resistance boards used in bathrooms really made of cement M2Tech and Diamond board?
Hydrophobic property make it moisture free.
