Anyone hear of or can suggest bricks that take longer for the heat to penetrate into the house, i.e. like a thermal brick if they exist, failing that I think I will have to go with a cavity brick wall using standard type bricks.

 

Reason I am asking is the wall will have the sun on it most of the day. 

I think they are called Q-con
aerated concrete block ?
remember that
(without aircon)
the house will still get upto the ambient outside temperature so 27-33 degrees C

Everyone around us building at the mo seems to be buying the large blocks from Global House 18 baht each suppose to be good at insulation.

This forum is a wealth of info, developed over many years by it denizens, er, Members.... The search function is your friend.  

 

yes, use an AAC block for exterior walls - the diff in heat transfer thru wall is amazing. protect your East & West facing walls from sun as much as possible and you'll feel the diff. so will your wallet if you use A/C. If you cant/won't shade these walls, coat them with radiant-reflective paint.

 

Auto Claved Blocks are available in every builders merchants store in Thailand. Most cement companies offer of brand of autoclaved blocks. Super Block is from Insee Cement.  Q Con is now owned by Siam Cement. Diamond Blocks are owned by Diamond Building Products. I've seen blocks range in thickness form 7.00 cm to the most common 7.5 cm, 10 cm, 12.5 cm, 15 cm, 20cm and 25 cm.  Most, AAC blocks are 20 cm high and 60 cm long. Steel reinforced lintels in most of the widths can be ordered in Thailand from most any builders merchants building supply store. Transport costs on the blocks play a role in the price you see locally. The Q Con web site and printed catalog has quite a bit of information in Thai and English. Autoclaved wall panels are also common for construction for high rise condominiums and commercial buildings. I've seen quite a few different brands of autoclaved home building products at the annual Architect Expo in Bangkok. Lanko and TOA make fiberglass mesh to use as a cover over the water pipes, electrical conduit or air conditioning pipes installed into autoclaved walls. I have used a temperature gun to see the radical difference in temperature outside a AAC wall and inside a home in Buriram. Well worth the effort of 4MyEgo to see the autoclaved wall blocks and lintels in his province. Local free or low cost delivery will make a difference in his home building budget. 

I've got no scientific proof, just subjective observation.

 

I built the house with cavity walls using those small red bricks. Got a monier tiled and insulated roof. House has standard windows and lots of fans. But expensive British Paints.

 

I built a garage from 10 cm Q Con blocks.

 

Standard windows and metal insulated roof. No fans.

 

The house is in more direct sunlight than the shed, but doesn't seem to get as hot as the shed.

 

When the house heats up it is more difficult to cool it than the shed. With the shed just introducing open windows and rolladoor seems to cool it.

 

So I think much of a muchness.

 

But, 7.5 cm QCon cavity walls and correctly installed and correctly insulated roof would be the trick.

 

Keeping the sun off the house is the way to go.

Gotya. [emoji3] What me over engineer? If I don't know what I'm doing, then it should be over engineered.
