Backloading for RibCore by Trusscore
RibCore™ by Trusscore® is a high-strength PVC corrugated panel that is long lasting, cost effective, and simple to install and maintain. Ideal for a broad range of agricultural, commercial, industrial, and even residential applications including on the ceiling. RibCore is engineered to support common types of insulation behind panels, often referred to backloading.
When used for ceiling applications at joist spans of 24" and 48", the following table can be used as a guideline to determine expected panel deflection based on the overall weight of the insulation above.
| 3" RibCore | ||
|---|---|---|
| Weight of Insulation (lb/ft²) | Deflection (mm/in) (3 Screws Along Joist) | |
| 24" On-Center Joist Spacing | 48" On-Center Joist Spacing | |
| 0.50 | 2.05 mm / 0.081 in | 2.92 mm / 0.115 in |
| 0.67 | 2.24 mm / 0.088 in | 4.43 mm / 0.174 in |
| 0.83 | 2.69 mm / 0.106 in | 5.26 mm / 0.207 in |
| 1.00 | 2.98 mm / 0.117 in | 6.04 mm / 0.238 in |
| 1.50 | 4.29 mm / 0.169 in | 8.62 mm / 0.339 in |
We do not recommend exceeding the maximum loading condition of insulation shown when using RibCore by Trusscore. Consult the RibCore Installation Guide to achieve the best results.
