This covering was placed on the sheathing directly above the attic opening. What’s it for?
As an aside, any tips on loading pics? No matter how I rotate the picture, it reverts to the original orientation when I load it to Inachi.
Was it next to a common fire barrier wall?
You can avoid the photo rotation problem by taking all of your pics in landscape orientation.
Yes. That’s a town home correct?
Yes to both. Town home and next to fire barrier wall. Is it really just drywall up there?
Was this a condo or duplex separation wall in the attic where 4’ on each side of the separation is required to have a thermal barrier?
Send your picture to Microsoft Office Picture Manager or use Photo Bucket.
No.
Each unit is required to have a one hour fire rated wall. Two adjacent town homes can share a common 2 hour fire rated wall if there are no plumbing, mechanical, duct, or vent installations in the common wall.
The fire wall must extend from the foundation to 30 inches above the roof ( a parapet). However, no parapet is needed if:
the elevation of the town homes differ by at least 30 inches, and the walls above the roof line are at least one hour fire rated
or
the roof coverings have a class C fire rating (which most do), and the roof sheathing is fire rated treated plywood for 4 feet from the edge of the fire wall, or if the roof sheathing has 5/8 inch type X drywall applied directly underneath it for 4 feet.
