What type of window do you have and how often you open it?
Some windows open in, out or up. The hardware on casement windows can get caught between slats while windows prone to a lot of moisture or condensation can make a fabric window subject to mildew.
West Facing Windows – allow in the fierce afternoon sun. Consider using horizontal or vertical blinds to protect fabrics and furniture.
South Facing Windows – offer hot, lazy light year round. Consider using horizontal or vertical blinds to protect fabrics and furniture.
North Facing Windows – offer clear, consistent light and the coldest exposure. Consider energy efficient shades such as cellular shades.
East Facing Windows – catch the warm, bright morning light. Consider horizontal or vertical blinds to block out UV rays.
