1. What is Rockwool Density?

Definition: Rockwool density refers to the mass per unit volume of rockwool insulation material, typically measured in kilograms per cubic meter (kg/m³).

Purpose: Density affects thermal performance, acoustic properties, and mechanical strength of the insulation.

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass (kg)
• \( V \) — Volume (m³)

Explanation: The mass of the rockwool is divided by its volume to determine its density.

3. Importance of Rockwool Density

Details: Rockwool density typically ranges from 30-200 kg/m³. Higher density products offer better sound insulation and thermal mass, while lower density products are lighter and easier to handle.

4. Using the Calculator

Tips: Enter the mass of your rockwool sample in kilograms and its volume in cubic meters. Both values must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical density for rockwool insulation?
A: Common densities range from 30 kg/m³ for lightweight products to 200 kg/m³ for high-density boards.

Q2: How does density affect performance?
A: Higher density generally improves sound insulation and fire resistance but may slightly reduce thermal insulation value.

Q3: How do I measure volume accurately?
A: Measure length, width, and thickness in meters and multiply them together (L × W × T).

Q4: Why is density important for installation?
A: Higher density products are more rigid and better for applications requiring structural support.

Q5: Does density affect price?
A: Yes, higher density products typically cost more due to increased material usage.
