- Acoustic suitability to expected background and activity noise levels
- Appropriate aesthetic appeal when finished
- Water resistance in wet areas
- Impact resistance, impact resistant materials should be used in all student accessible zones.
- Support sustainability by having recycling potential at the end of usable life, and/or include recycled content.
