Heat Transfer Rate Through Glass Calculator

Calculate Heat Transfer Through Glass

A measure of thermal transmittance.
The total area of the glass.
Difference between indoor and outdoor temperatures.

Use our Heat Transfer Rate Through Glass Calculator to quickly determine the thermal energy flow through windows or skylights. Input the glass U-value, surface area, and temperature difference to estimate heat loss or gain, crucial for energy efficiency planning and HVAC design. Simplify complex thermal calculations with ease.

Formula:

The formula for calculating the heat transfer rate (Q) through a material like glass is:

Q = U × A × ΔT

  • Q: Heat Transfer Rate (Watts or BTU/hr)
  • U: Overall Heat Transfer Coefficient (U-value) of the glass (W/m²·K or BTU/hr·ft²·°F)
  • A: Surface Area of the glass (m² or ft²)
  • ΔT: Temperature Difference across the glass (°C, K, or °F)

This formula helps quantify the thermal energy moving through the glass due to a temperature gradient.
