internal walls: better gasbeton or perforated?

[dadavolz]

hello to everyone, I am renovating an apartment and I needed your advice. . .

in particular the idea is to get two apartments from one and to do this I will have to throw down some tramezzi and raise new...

in the specific case would I need some advice on the possible use of gasbeton as an alternative to traditional perforations... what do you say, would you?

Is my doubt above all about the resistance of the wall (will it hold the weight of TV, or any other laying hanging or resting?????) and also, I go to encounter cracks of the plaster? ? ?

I finally take advantage to ask you which according to you is the best solution for the partition wall between the two apartments. . .
from the sound insulation point of view (but also heat), are two rows of flanked holes enough or would it be better to predict a row of perforated/gasbeton and a layer with forwarding panels? ? ?

I thank in advance who of you will want to help me.

I've never seen gasbeton in practice. the resistance depends on the desired composition, it can be varied and therefore you have to evaluate it with your supplier.
with regard to the wall partitions I would not satisfy the appearance sound insulation. two perforated files are a little, better two though of small thickness, but with a good layer of acoustic / thermal insulation.
thicknesses to be evaluated according to the product you choose.

Hello, first of all thank you for your answer... .

by re-epilogando you would recommend the perforated for the tramezzi (often? 10 cm?) and two perforated files + an intermediate layer of acoustic insulation....about the latter, what do you recommend??? and what thickness should I expect for these holes? not to lose too much space, but to have at the same time an excellent sound insulation, how thick should the wall be in total?

There are many solutions to be evaluated according to the general principles of the project. you could meter two 8cm holes with a central room of 4/6cm for there thermal and acoustic insulation.

As an alternative to the hole you could use the gasbeton, which though being a compound, you have to evaluate with the suppliers of your area the fische characteristics that they are able to get.

the insulating can be made in many different materials, there is wide choice. you have to consider the most suitable. For example, if you are building with principles of eco-sustainability, you could put (among others) of cork. If you don't have any of these problems, you could use a mix of wool, irondur and more. If you want to spend a little bit, you could opt for simple polystyrene, but over the years it tends to detonate. then depends on setting up your project. I suggest you compare with your technician and your suppliers
the scleta and varies as you can see from the catologist of a producer randomly taken from the networkhttp://www.cabox.com/pages/fonomur.htm

the typologies of tramezzi for interiors are various, and each has qualities and defects.
that in lapilcement has the advantage of being very solid and moderately flexible, bears punctual loads quite substantial (to be a tramezzo). of converse must be plastered (and therefore time of realization longer), is heavier, it takes more time to realize it

that in gasbeton (or cell concrete) has the advantage of being light, it poses very quickly, it only needs a final shaving to be "finished".
on the other hand it is very rigid (for which with time it will highlight the typical detachments from the contour structures (pillars / ceiling) and must be laid with a certain skill, because it has only a shaving (we speak of mm against the almost 2 cm of the traditional plaster) that separates the rough block from the paint.

the perforated block has the advantages of gasbeton (light and relative speed of laying), but it must be plastered, like laplcement.
punctual load resistance is less than lapilcement, due to the type of material and the considerable presence of gaps. often needs ad hoc fixings (parachute tags).
Plant performance on the kilns is a half drama. it becomes difficult to perform traces without shattering large parts of perforated. So then there's a need for quite challenging restoration as a quantity of materials.

acoustic insulation is decreasing when switching from punches, to lapilcement to finish to gasbeton, which due to its stiffness, behaves a little to slab effect, affecting sound insulation.
against the thermal insulation of gasbeton is the highest among the three methods.

as dividers between two apartments, it is worth more sound insulation than heat.
the temperature difference between the two sides (both inside) will almost never need a very large thermal insulation. becomes more important than the acoustic one. by experience, with even only a row of lapilcement from 20, you get dividers between perfect apartments.

My experience with gasbeton is negative. has many qualities but to see them emerge you must be in a rather homogeneous context. Consider that you don't put a real plaster on it but shave it and just any swing of the structure on which it is supported will generate cracks that will always remain visible.
perhaps this problem is less evident using the 30 cm thick blocks. I would avoid making "panini" with different masonry.

hello to all and thank you for your advice....
from what I understand this gasbeton is much less reliable than the kilns... so I think I'll tell the company that I prefer these last ones for the plots.. .
remains the doubt of the wall "division" between the two apartments. ..pilcement or perforated + panel x sound insulation??? (consider that the budget is not very high and that I would like to get the right compromise between "expenditure and surrender"). ...
