Attic Dams or barriers

If for insulating:

Figure the material times the R-value, gives the height:

“Attic access opening size (22” x 30”) and headroom above (30”) are same as U.B.C. However, IRC specifies that any attic space 30 sq. ft. or larger and a vertical height of 30 inches or more, must be provided with a complying access. (IRC 807.1) From: srcid=ADGEESg7brpyShHsa_W-oEf5YLqqM7TXJfq1D3zpsLxtBWWIEXDMOaPgySMzKBDQmAVJFz 5tVK-ImpdtaPrCPxo_1WwPKgwV54h_NxnNwTDTWr1jpRkJSS235ejV7 PaKE6xmg-x_8J4i&sig=AHIEtbSRoB1Wh4YY_-lBGGkPryQ1TVnW-A
