If beam span is 22 feet in length, then their depth = (22 × 12) ÷ 20 = approx 14 inches and width is 14/3 = approx 4″. So, you would need something like 3-1/2″ × 14″ size of LVL beam for a 22 foot span.

A single sheet is typically 48 inches wide (size 4' × 8'). Framing a stud wall at 16 or 24 inches OC will result in the edge of a vertical sheet falling over the center of a stud, as 48 is divisible by both 16 and 24. Thanks to this, the edge of the sheet is securely supported and backed by about ¾ inch of wood, which we can use for nailing.Attic without storage: Use Table R802.4 (1) Ceiling Joist Spacing: 12 inches.
