QCon Wall Panels vs blocks

Recommended Posts

Maybe your first time to DIY?  Yah - AAC blocks have been the favorite material for maybe 20-30 years now.  The builders love them and they are excellent insulation.  Most of us who have built homes with them have gone with a double wall (of 7.5cm) leaving a cavity for running PVC for water and electric.  Cheers.

He is not talking about AAC blocks, what he is asking about is AAC panels (60 cm x 300 cm). I have not heard about anyone building with these in a domestic setting.

Oh, right.  I don't see where there's much difference though.

Use what you want as long as you have an air cavities all down to labour cost really stud wall goes up quick and there's little or as much finishing work as you specify.

Since they can be up to 3m long and 60cm wide they could be pretty much instant wall.

 

Be interesting to see if anyone uses them @FireMedic fancy being the guinea pig?

I've seen posts that say never have a wall cavities, citing problems with vermin, etc. I hope I can get a definitive on that, since I plan to build this year. Thanks.

Hopefully construction will not leave holes or gaps where the larger critters can get in.  Ants will invade the smallest of cracks and not much can do except laying down the dust and spraying when they get too personal.  Cavities make a convenient space to run water and electric without having to grind out the races.  And they can hide the columns.  With AAC block, there is no insulation advantage to the cavity.

That is nonsense.. I had people tell me the same thing when I was building..  7 years later no problem with vermin or moisture.. A cavity wall creates a room with very stable temperature ... cheap to air con.. & quiet. I used the insulating block for outside skin.. normal concrete blocks inside.. rendered inside and out with cement render.. You need good footings and foundation to prevent cracking..

We use the panels in more commecial buildings due to the size. Useful for quick construction for large areas, i wouldnt see you gettimg the same advantage on a domestic build.

It is impossible to get a definitive answer. Do it correctly and there are no problems, (most do, we did, we don’t have problems) do it badly and have all the problems of dead corpses or active infestations.

The OP might want to look at the video and then look at his local labor force. The wall panels make sense for a major contractor who is doing many walls with no windows. If the contractor is willing to invest in the tools and training. Normal AAC blocks seem within the scope of local home construction crews. The weight on the wall panels, might be a deal breaker for most local crews. There are other walls panels on offer at the Architect Expo, and for condo builders or office builders certainly a strong contender.

Has anyone used these yet for residential housing walls? Supposed to be faster, more efficient, no cracks etc ........... 

They are very used in my Scandinavian home country – aerated concrete blocks and panels originates from Sweden, and have been used for generations since the 1930s, the method was patented in 1924 – and yes, they are both fast, efficient, and if build right they are without cracks. You can actually build a whole house from aerated concrete bricks only, with no posts, and no heavy stone walls...👍

 

I've used aerated blocks and panels in my home country, and aerated block in my house here; the panels were not yet (widely?) available in Thailand, and the Q-con blocks a fairly new products 12 years ago, when I began my Thai house construction..🙂

It's very easy to cut, or saw, out holes for openings like doors, portals and windows after the wall is build. Same for cutting rails for hidden electric pipes and cables...:thumbsup:
