1 Inch blinds are the perfect option for a weightless and cost-effective window covering. When these blinds are open, they allow for less light to shine through compared to a 2 Inch blind. 1 Inch wooden blinds provide better insulation to keep the outside temperature from affecting the temperature in your home. In addition, they close tightly to prevent sunlight from penetrating through the sides of the window frame and, just like metal blinds, they open compactly to the top of a window for cool spring and fall days when windows are opened and fresh air is desirable.
