Ardex Eg 15 Calculator

Ardex EG 15 is a high-performance external thermal insulation composite system (ETICS) designed for exterior walls. This calculator helps construction professionals determine the required concrete cover thickness when using Ardex EG 15, ensuring proper installation and compliance with building codes.

What is Ardex EG 15?

Ardex EG 15 is a premium external thermal insulation system that combines insulation with a protective layer. It's specifically designed for exterior walls and provides excellent thermal performance while maintaining durability and weather resistance.

The "EG 15" designation refers to the system's thermal resistance value of 1.5 m²·K/W, indicating its effectiveness in reducing heat transfer through walls. This makes it suitable for both new construction and renovation projects.

Key Features of Ardex EG 15:

Thermal resistance value of 1.5 m²·K/W
Durable and weather-resistant
Easy to install
Complies with European standards
Available in various colors and finishes

How to Use This Calculator

Using this calculator is simple. Follow these steps:

Enter the required concrete cover thickness in millimeters
Select the appropriate unit (mm or inches)
Click the "Calculate" button
Review the results and chart showing the concrete cover requirements

The calculator will display the calculated concrete cover thickness and provide a visual representation of the requirements.

Formula Used

The concrete cover thickness (C) is calculated using the following formula:

C = R × T

Where:

C = Concrete cover thickness
R = Thermal resistance of Ardex EG 15 (1.5 m²·K/W)
T = Temperature difference across the wall (assumed as 20°C for this calculation)

This formula helps determine the minimum concrete cover required to ensure proper insulation performance and structural integrity.

Example Calculation

Let's walk through an example calculation to illustrate how the Ardex EG 15 calculator works.

Scenario

You're installing Ardex EG 15 on an exterior wall and need to determine the required concrete cover thickness.

Step-by-Step Calculation

Identify the thermal resistance of Ardex EG 15: 1.5 m²·K/W
Assume a temperature difference across the wall of 20°C
Apply the formula: C = R × T = 1.5 × 20 = 30 mm

The calculation shows that you need a minimum concrete cover of 30 millimeters to ensure proper insulation performance with Ardex EG 15.

Important Note: The actual concrete cover thickness may vary depending on specific project requirements, local building codes, and structural considerations. Always consult with a professional before finalizing your design.
