What it is
Sheathing is part of framed construction in timber or steel: plywood or cement boards go on the frame, then waterproofing and cladding.
Key points
- Plywood, OSB or cement board
- Braces the frame
- Base for cladding or roofing
- Needs waterproofing outside
Why it matters
It is rare in brick-and-concrete Chennai homes, but you will see it in lightweight extensions and terrace rooms.
How Elamentt handles it
For lightweight terrace rooms or extensions, we choose boards suited to the weather.
