An acoustic ceiling or wall liner from this shop is a thin GI perforated sheet plus a backing pack. It is not an architectural perforated pattern, and it is not a corrugated sheet.
Sheet
| Gauge | Thickness |
|---|---|
| 22 g | 0.60 mm |
| 24 g | 0.50 mm |
| 26 g | 0.40 mm |
Holes are 3 mm or 5 mm. Rolls are from 1 m to 4 ft. Pick the hole first, then the gauge. A 26 g sheet is the lightest of the three. A 22 g sheet is the stiffest on this list.
Backing
Tissue paper and glass wool are a separate listing. Say the area and the wool thickness on the same enquiry as the sheet, or the liner arrives without the pack.
