- Adhered System
Choose an adhered system design from the calculated uplift pressure to determine the number of fasteners or adhesive ribbon spacing to be used for that tested approval. For the complete code assembly refer to Carlisle Code Approval Guides for additional information.
Example: Test Approval Pressure = 90-PSF. One option would be to use 2” thick polyisocyanurate insulation fastened with 8 fastener and insulation plates per 4’ X 8’ size board.
