1. What fire class does this board meet?
It’s treated to achieve a reaction to fire Class B to EN 13501-1 (supplier/spec dependent).

2. Is 5.5mm thick enough for structural work?
5.5mm is typically used for linings, cladding and set building. For load-bearing floors or shelving, choose a thicker board.

3. Can I paint or laminate this plywood?
Yes. The smooth faces take paint, veneer or laminate. Use compatible, fire-safe coatings where required.

4. Is it suitable outdoors?
Use indoors or in protected areas only. For exterior exposure, pick Marine Grade Plywood and always seal edges.

5. Can you cut it to my sizes?
Yes—order via Flame Retardant Plywood – Cut to Size for clean, CNC-accurate parts and less waste.

6. Looking for a value alternative for hoardings/sheathing?
