🛠️ Polystyrene Bead Insulation Volume Calculator

Do you want to improve the thermal and acoustic insulation of your home? Our volume calculator helps you precisely determine the quantity of polystyrene beads needed to insulate a hollow wall, floor or ceiling.

💡 Why Choose Polystyrene Beads for Insulation?

Polystyrene beads are an effective, economical, and eco-friendly insulation solution. Here are their main advantages:

  • Optimal thermal insulation: reduces heat loss and improves energy efficiency.
  • Acoustic insulation: absorbs noise and reduces noise pollution.
  • Easy installation: lightweight and easy to inject into hollow walls.
  • Moisture resistance: prevents the formation of mold.

📝 How to Use the Calculator?

Our tool allows you to estimate the necessary volume of insulation in a few steps:

  1. Choose your calculation method: enter the dimensions of your space or a surface in m².
  2. Indicate the desired height of the insulation.
  3. Instantly get the volume in liters and in m³.
  4. Order your polystyrene beads for insulation now!

❓ Frequently Asked Questions


📌 How to inject polystyrene beads into a hollow wall?

The beads can be blown in with an injector or simply poured into the space to be insulated.

📌 What is the insulation coefficient of polystyrene beads?

Their thermal coefficient is about 0.030 W/m.K, which guarantees excellent insulation.

📌 How many liters of polystyrene beads for 1 m²?

It all depends on the thickness of the insulation, but on average, for insulation 10 cm thick, use the volume calculator.
