Attic Insulation

Air conditioning, fans, and anything related to keeping it cool, such as insulation. This would include any posts generally discussing how to keep it cool, such as which types of blocks are better insulators.... ideal wall thickness for keeping an A/C house cool, etc.

What is the best product available, in Thailand, for insulating the ceiling above Gypsum board? Brand names, types of material, installation tips, etc would be greatly appreciated.

What is best is a matter of opinion. We purchased Stay-Cool R-23 batts .60 X 4.0 meters incased in foil. Not yet installed, because the sheetrock has not been hung. If it had not been on sale we probably would have purchased R-11.

Thanks Rucus7 I have seen a product at Homopro in CEX but could not remember the brand name. I do not really care about best as long as it works. We installed foam between brick outside and panelling inside. Now trying to decide on Aircon brand....leaning toward York or Carrier which mounts on wall at floor vs. ceiling hung.

rucus7 How about posting a few pictures of your build. As they say one picture is worth a thousand words.

Thanks rucus, missed them sorry.
It might be an idea to put this in your signature.

http://www.coolthaihouse.com/cthpics/th ... y&uid=1505

It will help the members find your pictures.

Or start a new thread if you want comments. :D

I can see from the pics from Rucus that the insulation material is applied on top of the ceiling and not directly underneath (against) the roof tiles.

Suppose that you have an existing ceiling would it be possible to add a layer of insulation material on top of that? Or do you need to make an extra construction for that?

Thanks,

Fritz

Fritz insulation is like a thermos it works both ways

my preference would be
No 1 lots of money sprayed foam to underside of roof
No 2 reflective foil on uderside of roof causing convection currents drawing cooler air from the soffits so venting is important to create air flow also benifits by stopping radiated heat building up in the roofspace
No 3 probably the most common is a wool blanket on the ceiling stops heat entering the room through the ceiling but will also stop heat leaving the room the same way so can be counter productive although very worthwhile if used with aircon

These are my preferences and in order of favorite
my comments may be wrong but never deliberately
If it aint broke, dont fix it

I think it could be laid on the existing ceiling.

Hi Thanks for your reply! That's what I thought as well. It's insulation wool that I'm after. The other options wouldn't be feasible/affordable for me as the roof is already on the house.

I can assume that the bugs residing in Thailand don't take a liking in insulation material... ?
Besides the insulation material incased in foil is there any kind of coating/repellent that needs to be sprayed on it to keep it clear from unwanted residents?

Any ideas on prices ranges for rolls of 0.6X4.00 m?

For us it serves a double purpose: first to increase the efficiency of our air conditioning unit and second to keep unwanted noise out. I noticed that a lot of noise comes into the bedrooms through the roof/ceiling.

Many thanks,

Fritz

I have never heard of anybody complain of bugs or insects in their insulation. I think it is laid as it is and no extra protection is added.

In some building stories there might be some prices. I know that Max used it in his Building an Australian House. Try to search for "insulation" or "ceiling insulation".

Hi Fritz,

I think we paid around 275 baht per roll. Less than 300 for sure.

The name may be "STAY COOL" and is made by Siam Cement (http://www.siamfiberglass.com/products_green.php)and available at most large builder shops. We buy in Chiang Rai or Phayao.

The Thai name is "Chanone" or something like that.

You should not worry about pests. Just seal the soffets with screen material.
