Kingspan U Value Calculator Ireland

Kingspan U-Value Calculator Ireland is an essential tool for architects, builders, and homeowners to determine the thermal performance of Kingspan insulation products. U-Value, a measure of heat transfer, is crucial for energy efficiency and compliance with building regulations.

1. Enter the thickness of the insulation in millimeters.
2. Select the material type from the dropdown menu.
3. Click the ‘Calculate’ button.

The calculator uses the following formula to calculate the U-Value:

U = 1 / (t * λ)

Where:

• U is the U-Value (W/m²K),
• t is the thickness of the insulation (m), and
• λ is the thermal conductivity of the material (W/mK).

Thermal Conductivity of Kingspan Materials (W/mK)

Material	λ
Polyurethane	0.022
Polystyrene	0.035
Extruded Polystyrene	0.033

• Thicker insulation provides better thermal performance.
• Consider the overall U-Value of the building envelope.

What is the U-Value?

The U-Value is a measure of heat transfer through a building element, such as a wall, roof, or floor. It is expressed in W/m²K.

Why is the U-Value important?

The U-Value is crucial for energy efficiency and compliance with building regulations. A lower U-Value indicates better thermal performance.
