压条间距多少合适？

按所选板宽在 20–60 厘米中心距之间。30 厘米适合大多数住宅；间距更大偏现代，更小偏传统。

5–7.5 厘米。它必须盖住板缝并在两侧各压住至少 1.3 厘米，这样干燥季节木材收缩时仍能保持密封。

先装宽板还是先装压条？

先装宽板，再把压条盖在接缝上。宽板只在靠近中线处钉固以便伸缩，压条则穿过板缝钉入，而不是钉穿板材。

板条墙板用什么木材？

雪松和红杉天然耐腐，涂底漆的松木或云杉是经济之选，纤维水泥板则维护量最低。潮湿气候下材质选择比钉法更关键。

能直接装在旧墙板上吗？

在平整基面上加木龙骨条可以。旧的是搭接板材时，需先找平。两种情况下后面都要有防水膜，龙骨条必须钉在立柱上。

Result

Boards

31 × 9.0 ft

Battens

31 × 9.0 ft

Wall area (net): 216 ft²
Board linear feet: 279 ft
Batten linear feet: 279 ft
Waste: 10%

Waste default: 10% — 10% 用于洞口周边的裁切以及有缺陷板材的挑除；开窗较多的墙面提高到 15%。

公式

宽板数 = (墙宽 ÷ (板宽 − 2 × 搭接)) × (1 + 损耗)

参考资料

Measure what the tool asks for
This calculator works from 墙面宽度 in ft, 墙面高度 in ft and 宽板实际宽度 in in. Measure the finished area you are covering, not the material — an estimate is only as good as the dimensions you feed it.
What it does with those numbers
宽板数 = (墙宽 ÷ (板宽 − 2 × 搭接)) × (1 + 损耗) Every figure on the page comes out of that one expression, so you can check it by hand.
Why it adds 10% waste
10% 用于洞口周边的裁切以及有缺陷板材的挑除；开窗较多的墙面提高到 15%。
Where the numbers come from
The constants are taken from Western Wood Products Association — Siding installation guidance and IRC R703 — Exterior covering and water-resistive barriers, linked in full below. If a figure here disagrees with your supplier's spec sheet, use the spec sheet — it describes the product you are buying.
What this will not tell you
This is a material takeoff, not a bid. It does not price labour, permits, delivery, equipment hire or site preparation, and it assumes a straightforward layout. Complex cuts, difficult access and awkward shapes all cost more than the geometry suggests.

常见问题

用墙宽除以一块板的有效覆盖宽度——实际板宽减去两侧搭接——再加损耗。每条接缝配一根压条，因此压条数与板数相同。
