挂板面积怎么算？How is the siding area worked out?

墙面 = 周长 × 墙高（到屋檐）；每个山墙是三角形，面积 = 底宽 × 高 ÷ 2；两者相加再减去门窗面积，最后加 10% 左右的损耗。默认例子：160 × 9 = 1,440，加两个 30 × 8 的山墙 240，减门窗 200，得 1,480 平方英尺，加 10% 约 1,628 平方英尺。Walls = perimeter × height to the eaves; each gable is a triangle, base × height ÷ 2. Add them, subtract doors and windows, then add about 10% waste. Default example: 160 × 9 = 1,440, plus two 30 × 8 gables (240), minus 200 of openings = 1,480 sq ft, or about 1,628 sq ft with 10% waste.

「方」（square）是什么？What is a square?

北美挂板和屋面材料常用「方」作单位，1 方 = 100 平方英尺（约 9.29 平方米）。不足一方通常按整方订购。Siding and roofing in North America are sold by the square: 1 square = 100 sq ft (about 9.29 m²). Part squares are usually rounded up when ordering.

损耗留多少合适？How much waste should I allow?

简单矩形墙面约 5%–10%；有很多转角、窗户或复杂山墙时可留 15% 左右。About 5–10% for plain rectangular walls; around 15% with lots of corners, windows or complex gables.
