Drywall 계산기

� 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�.
