Panel thickness should be matched to the application, not chosen by habit.
2-inch panels are common for partitions, false ceilings and general roofing in warmer, non-critical spaces.
3-inch panels are the most widely used thickness for factory sheds and warehouse roofing and walls across Pakistan, offering a good balance of insulation and cost.
4-inch panels are reserved for cold storage, pharma rooms and any application where temperature control is critical to the business.
