Filmface Shuttering Plywood Density Calculation: Easy Formula & Step-by-Step Guide
📊 What is Filmface Shuttering Plywood Density?
Plywood density refers to the mass per unit volume of a plywood sheet, usually expressed in kilograms per cubic meter (kg/m³). It depends on the type of wood, adhesive content, and manufacturing process.
💡 Why is Plywood Density Important?
✅ Determines Strength & Durability – Higher density plywood is stronger and more impact-resistant.
✅ Affects Weight – Helps in selecting the right plywood for load-bearing structures.
✅ Influences Workability – Low-density plywood is easier to cut, while high-density plywood offers better resistance.
✅ Impacts Cost & Application – Different densities suit specific applications like furniture, flooring, or industrial use.
✅ How to Calculate Plywood Density?
Follow these simple steps to determine plywood density accurately.
🛠️ Step 1: Gather the Necessary Tools
You’ll need:
- 🧰 A Measuring tape or Scale
- ⚖️ A weighing scale
- 📝 A calculator
🔢 Step 2: Measure the Plywood Dimensions
Use a measuring tape to record the length (L), width (W), and thickness (T) of the plywood sheet in meters (m) or centimeters (cm).
🔢 Step 3: Calculate the Volume
Use the formula:
👉 Volume (V) = Length × Width × Thickness
This gives the plywood’s volume in cubic meters (m³) or cubic centimeters (cm³).
⚖️ Step 4: Weigh the Plywood Sheet
Place the plywood on a weighing scale and record its weight (W) in kilograms (kg) or grams (g).
⚖️ Step 5: Calculate the Plywood Density
Now, apply the Density formula:
👉 Density (D) = Weight (W) ÷ Volume (V)
where:
- D = Density (kg/m³)
- W = Weight (kg)
- V = Volume (m³)
📈 Example Calculation (12 mm – 8 x 4 Feet Filmface Plywood Sheet)
Let’s assume you have a standard 8 x 4 feet plywood sheet with the following details:
- Length = 8 feet = 2.44 meters
- Width = 4 feet = 1.22 meters
- Thickness = 19 mm = 0.012 meters
- Weight = 34 kg
Calculate the Volume:
👉 V = 2.44 m × 1.22 m × 0.012 m = 0.0357 m³
Apply the Density Formula:
👉 Density = 34 kg ÷ 0.0357 m³ = 952 kg/m³
Final Result:
12 mm – 8 x 4 = 34 kg – Density = 952 kg/m³ or 0.95 gm/cm³

🔄 Factors Affecting Film Face Shuttering Plywood Density
🌳 Wood Type – Hardwood has a higher density than softwood.
🧱 Glue Content – More adhesive increases density.
🛠️ Manufacturing Process – Compression levels during production impact density.
🌧️ Moisture Content – Higher moisture can lead to inaccurate density measurements.
