Which method has seams staggered?

• A. Nesting
• B. Double Layering
• C. Both
• D. Neither

Answer: (B)

Seams staggered means keeping the joints of one layer away from the joints of another so there isn’t a continuous gap through both layers. This is achieved by double layering, where a second layer is applied with its seams offset from the first. By offsetting the seams, you break up any straight heat path and improve overall insulation performance. Nesting focuses on arranging pieces to reduce waste, not on aligning or offsetting joints between layers, so it doesn’t inherently ensure seam staggering. That’s why double layering is the method that achieves staggered seams.
