In daily life, people spend most of their time indoors. This situation increases the need to keep indoor
environments warm in winter and cool in summer. This directly increases energy consumption. Since energy
dependence is dependent on fossil fuels and causes severe environmental pollution, energy consumption can
be significantly reduced with insulation applications to be made in buildings. Windows are responsible for
approximately 40% of the heat transfer in buildings. For this, reducing heat losses through windows can
significantly reduce energy consumption. This study aims to restrict air movement with barriers in doubleglazed
windows. By preventing the air movement between the double glazing, the natural convection effects
will weaken and decrease the heat transmission coefficient. The 2D CFD model is verified by using ANSYS
engineering commercial software and the heat transfer coefficient (Uw) of the insulated glass with air within
20 mm is determined as approximately 1.6 W/m2K. Then, the change in the heat transfer coefficient of the
insulating glass is evaluated with differently positioned barriers. It is seen that the barrier placed diagonally
reduces the heat transfer coefficient. It is seen that the heat transfer coefficient of the insulating glass with the
barriers placed in two different ways is 1.4 W/m2K and 1.52 W/m2K, respectively. Similarly, it is understood
that the thickness of the insulating glass also affects the heat transfer coefficient. This study shows that the
heat loss from the windows can be reduced by up to 12.5% by using a barrier.
