我需要多少干墙 12x12房间?

一个有8ft天花板的12x12房间需要约16张4x8干墙的床单,仅供墙壁使用. 再加六为天花板.

我应该用4x8还是4x12床单?

4x12床单意味着接合更少,安装更快,但它们更重更难处理. 使用4×12来作长墙,4×8来作更小的区域.

每张干墙有多少个螺丝?

每4x8平板使用大约32个螺丝(边缘为每12英寸1个,田地为16英寸). 大约是每平方英尺一螺丝.

我需要多少联合大院?

大约每50平方英尺干墙有一桶4.5加仑您需要更多的纹理完成或录入许多接缝.

Drywall & Insulation Calculation Formulas

� Wall Area: Perimeter = 2 � (Length + Width). Area = Perimeter � Height.Net Wall Area = Wall Area - (Doors � 21 sq ft) - (Windows � 12 sq ft)

� Total Area & Drywall Sheets: Drywall Area = (Net Wall Area + Ceiling Area) � (1 + Waste Margin).Drywall Sheets = ?Drywall Area � Sheet Size Area?

� Insulation Roll Requirements: Based on selected target R-Value coverage and wall dimensions (Length L � Height H).Insulation Area = L � H (or Net Wall Area for Room)Rolls Needed = ?Insulation Area � Roll Coverage?

� Standard Roll Coverage: R-13 = 40 sq ft/roll | R-19 = 49 sq ft/roll | R-30 = 31.25 sq ft/roll | R-38 = 32 sq ft/roll. Metric conversion: 1 sq ft � 0.0929 m�.
