Internal Wall Vents

[Artisi]

Anyone with any idea where I might source a number of internal wall vents so as to vent rooms into a cavity wall space.

Pic of a typical Aussie wall vent - anything to do the same job wil suffice.

Thanks.

Sorry Artisi, not sure where you would get them. But seeing as you are familiar with this venting system it would be great to hear some comments about it in the following thread. http://www.thaivisa.com/forum/topic/432933-how-to-properly-insulate-ventilate-double-blockbrick-walls/

I keep hearing that some areas of AUS are very similar to LOS. That is why I would be interested to read about the method you are refering to if your care to type about it.

You can buy similar wall vents anywhere but the bugs get in. You must construct your own mozzy protection when these blocks are fitted. Thai's will not understand, you must be present to fix a mozzy screen to the blocks.

Please enlighten me where anywhere is, I've looked in all the likely places - but nothing - unless you are discussing concrete block type vents.

Open "breeze" blocks should be fairly easy to find at any place that sells concrete blocks... (Building supply stores)

They should be available in various patterns... (these could also be used for driveways & pathways etc.... about 12 -14" x 6" by three or four inches wide, (same size as the full blocks).

Any aluminum window making shop should be able to make up an aluminum screen to cover the opening, there by preventing the mossies & other insects getting in... (all made to size & screwed in, to fully cover) ... so you can make vents as big or small as needed. .... the mesh is aluminum also, so does not rust....

When I had my windows & screens done it was fairly inexpensive to do....(windows also with sliding or opening screens )....

I'm not sure what material was used to construct that wall vent in the pic you posted Artisi. But if you are looking for something a little fancier than the concrete breeze blocks typically used in Thailand you could use pvc. The windows in my house are all pvc and I also had the company (Windsor) make up some customized pvc lattice for me. I'm sure they could make you up something similar to your picture and then could by some bug screening to install on the backside of the vent (for a better look than on the front). Good idea to have it built so you can somehow get at the screen to clean dust and cobwebs from time to time.

*just make sure to clarify that you want no silicone anywhere as they may take it upon themselves to seal up any crooks or crannies thereby ruining the finished look*

Thanks to all, before posting I looked in all the likely places - but nothing, so I sketched what I wanted and asked the local sheet-metal shop to price it, that was no problem as we decided to used pre-punched sheet backed with fly-screen - the problem was the price, about Bht700 each which is over the top for the function.

Ok, so fancy isn't what you are after and my previous suggestion will surely be more expensive than 700 baht. For cheap options I only know of two, both concrete blocks.

1. same size dimensions as a typical concrete building block with one (or two?) angled (on a 45 degree) slits horizontally. usually used in as the upper wall section where natural ventilation is used exlusively (temples, pumphouses, etc.)
2. a bigger (same size as 2 of the above stacked) with a more ornamental design (flower cutout for eg.) in leau of the slits.

Both choices should be available at almost any family run outfit selling concrete building items.

Cover up your furniture with sheets. Don safety glasses, dust mask, and pop in some ear plugs. Now fire up that gas powered block cutting saw!
