Wood for humid weather?

[nicole_DIY]

Does anyone have any experience with wood and humid weather? Thoughts?

Could you be somewhat more specific? What type of wood? How humid? The more information you can give, the more useful an answer will be.

Philippines humid? I'll look up the technicalities. I'm thinking of Narra wood or Mahogany?

There are two issues with wood in humid conditions;
1) As it absorbs water and then dries out it swells and contracts changing shape - dimensional stability is a measure of how much each type of wood changes shape in this way. Movement can be in both radial and tangential directions (thickness and width). If you are using wood for window frames or door frames if it changes shape too much you will have issues opening and closing and with maintaining a good seal. So for these types of applications, you need to choose a wood that has good dimensional stability.
2) Rot. Mould, fungus and bacteria like humidity. So if your wood is in humid conditions you need a species that is resistant to attack by microorganisms. This often means you need to use a treated wood or apply a treatment. You can do a Google search to find out relative decay rates of specific species - I have attached an example as a jpg.

Hi,

Western Red Cedar is expensive but durable?
