Timber moisture and treatment recorded for this climate
Why — act while you have leverage
Unseasoned timber in Kerala humidity warps and invites borer. A door that fits at handover and jams every monsoon is a timber decision, not a carpentry one.
What to look at
- Species named on the invoice, not a category
- Treatment record dated before fabrication
How to check it yourself
Timber is seasoned to the moisture content the standard permits for this zone and treated before fabrication rather than after. Ask for the species by name and the treatment record; "hardwood" on an invoice names nothing.
Where this comes from: IS 401 — preservation of timber; IS 287 — permissible moisture content for timber (indian standard or building code)
