    Interior wall construction.

    I was just watching this video and it raised a few questions.



    1 ) To me, it looks a bit fragile but not being an expert I was wondering how strong something like this would be ?

    2) Obviously not using cement so whats that stuff he's using to bind the bricks together ?

    Q blocks or Super blocks. Glued together.

    Can cut with a knife, allegedly.

    My mate built his entire house out of them. Swears by the stuff. Pretty expensive, I believe.

    Looks like grout for tiling from the way he's applying it. I work in construction and havent seen this before, I cant work out why you wouldnt just use normal mortar or make an internal stud wall.

    Posted at the same time as Jandajoy...Never heard of these blocks, what are the advantages over a normal wall or partitioning supposed to be, especially as theyre more expensive? Just that they're easier and quicker to lay?

    They are very light compared to the normal bricks (good for internal walls), and as they contain a lot of air provide very good thermal insulation for outer walls.

    Quite stable, but don't have a sumo fight in your house.

    I watched a rental apartment building go up near my place (BKK) and both the exterior and interior (dividing) walls were red bricks and mortar - but only about half the thickness of your average western brick. A couple of strong kicks and you could knock a wall out.

    Thats what I meant. They don't look to be keyed into anything or each other much. One drunken lurch against the middle of it might bring it all to grief ?

    Not like that. The special glue used for those stones will hold them firmly together. If something gives it is the stones themselves. Also you can hang heavy cabinets to them.

    they are strong but light, good for Insulating sound and tempeture, we did all our Bedrooms and Lounge + Office internal walls, House is a mere 300sq mts.

    Rendered the inside and outside after, Place is like a Cool Room, white tiled roof helps.

    I am using these blocks in my new house, But mine are 150mm thick, Those look about 75mm. I was worried about the strength but I talked to a guy that just finished his house using them and he said he was happy with them. Only time well tell for me.

    Theese block are called "Comfort blocks" in Thailand and are a quite new product. They have been used for ages in Northern Europe, made of cement and air bubles (in Scandinavia called gas cement), which gives a very high heat insulation. They are glued together with a special cement-glue (something like, when gluing tiles) and that glue is extremely strong. The blocks are light in weight and easy to handle. You can saw them with a normal saw, but there are special saws for that kind of blocks. You can even saw nice bows. They are nomally also made in large sizes, so you can raise and glue an inner wall together in "no time".

    The benefit for using them in Thailand is, that the gives a good insulation in rooms with aircons - keeping the cold air inside, just like keeping the warm air out inside in Northern Europe. I used them in the house I've been building in Thailand and I am very happy doing that. You can really feel a difference.

    If you make double-walls, you may choose the normal cheap block as outer-wall and the comfort block as inner-wall only. The price for the comfort block is 4-5 times the normal cheap block. But it is worth spending that little extra amout of baht when building, compared to the money you may loose, using too much power for aircons - and in general not having the sun heating the room walls too much. I used comfort blocks as both inner and outer wall for aircon rooms in my house, but I used the normal blocks only (to save construction costs) for ouside walls, fx. at a balcony. However, your can really feel the difference, when the sun is heating on a wall. At the end I decided to make extra comfort block balcony inner walls, to keep a comfortable temperature in the balcony shadow.

    If you are making a double wall, with both a heavy brick wall and a comfort block wall, they best way is actually to have the comfort blocks as the outer wall, as the heavy stones keeps a more constant temperature - i.e. in Thailand the cooler temperature inside the aircon room.

    About strength: In Scandinavia we have since the 1960's been building whole houses of 150mm comfort blocks only, not using any cement post. They are strong enough to hold a tiled roof construction and the houses are, some 40-50 years later, still standing strong.
