Wood quality for doors and windows

Postby thomas.fontaine » Fri Oct 10, 2008 6:58 pm

We shop around all afternoon today to look for wooden doors and windows around Kho Kaen. Many specialised shops in wooden things there. Prices that we were given from one shop to another were very different, especially if doors and windows were made of Mai Sak grade AA or AAA. Grade AAA seems to be almost 50% more expensive than grade AA, eventhough they visually look the same. The prices of AAA were always given after a long explanation on how good it was for our house. But I couldn't really understand why it was so much better. Grade AAA is coming from bigger trees and all that...but do we care?

Is grade of Mai Sak something we should pay attention to or should we just go for the cheapest prices (AA)?

I realize I'm not answering your question. But, IMHO rather than considering Mai Sak, whatever grade, why not look at Mai Takien or Mai Nathasia (the latter coming from New Zealand). From my research, Mai Takien was a very good hardwood for exterior doors. It won't last as long as Mai Sak (teak), but neither will the rest of the house, probably. I've been convinced that Mai Takien is good enough, and it's considerably cheaper than Mai Sak.

Well, the reason being the 3 shops I have been to had only Mai Sak doors and windows. I will try to see if I can find Mai Takien somewhere

I have no idea what AA or AAA means with regard to wood, but when shopping for construction timber, doors, etc. I think the most important questions are: 1) what type of wood is it? 2) Is it kiln-dried? 3) Is it core wood? 4) Is the grain attractive? 5) How large are the individual pieces? Probably all of these factors determine price. If it's teakwood, then there are two more questions: 6) Logged or recycled? 7) Was it logged legally?

Aie aie aie, that's too many questions for my small brain to find the right product. From the few explanation I understood from the shop, I thing grade is probably in relation to your 3rd point, core wood or not. Not sure. They were always talking about "AAA, good, better for you, big tree.." (?!?) But what "big tree" means...

I my memory serves me right, teak wood needs many years before the pores in the wood fills up with the resin that makes it pest and weather resistant. So the bigger the tree, the older it is, thus more resistant aka higher grade.

And yes, core wood is filled with resin and it therefor the highest grade.

We see this clearly here in Norway, where 100 year old window frames from core of pine is still in mint condition, and modern, treated windows from the 70's now needs to be replaced due to decay.

Perfect. Thanks for your explanation, I know what "big trees" means now.

Given that AAA grade is twice more expensive than AA, I will go for AA then and change my set of doors and windows in 40 years

4 years later, what are the names to look out for from cheap medium to peng maak. Is teak the best?

I don't know the definitions of what A AA and AAA are, but as stated correctly by another teak develops resins only with age. Teak from a tree less than 15 years old has no termite resistance, thus you want a big tree for that. Like other trees, there is heartwood at the center and undesirable sapwood at the edges which are easily observed by the color difference. In order to get heartwood, again you need a big enough tree and cuts that don't go into the sapwood edges. I would imagine for marine purposes they insist on nothing less than heartwood from big trees, whatever grade that might be.

If as someone suggested you select Mai Takien instead which is excellent, never, ever admit that to any Thai person. They are universally afraid to death of this tree believing it contains ghosts and don't want to be anywhere near it. It's pronounced "my duh-key-uhn". Just utter that word and you should get a reaction.
