Many homeowners hand the plywood decision to the carpenter and only see the result when the bill arrives. A bit of knowledge puts you in control of both the quality and the cost.
What to know in five lines
- MR is for dry rooms. BWR is for kitchens and humid places. Marine is for wet zones.
- 18 mm is the common carcass thickness. Back panels are thin.
- Brand and range affect price as much as grade.
- Laminate is just the skin. The board underneath matters.
- Sealed edges prevent most failures.
Ask your carpenter or designer
- Which grade and brand for each item?
- What thicknesses?
- How many sheets are included in the quote?
- Which laminates (codes) and how many sheets?
