Blocking the sun from windows can be achieved through various methods to reduce glare, heat, and UV rays. Here are several options:

1. Curtains or Drapes:
2. Choose heavy, light-blocking curtains or drapes to effectively block sunlight.
3. Install curtain rods that extend beyond the window frame to prevent light from leaking around the edges.
4. Consider curtains with reflective backing to bounce sunlight away.
5. Blinds:
6. Install blinds made of materials that block sunlight effectively, such as wood or aluminum.
7. Angle the blinds to direct sunlight away from the room or close them completely.
8. Vertical blinds can be useful for large windows or sliding glass doors.
9. Window Film:
10. Apply reflective window film to reduce glare and block UV rays while still allowing light into the room.
11. Tinted window film can also be used to reduce brightness and heat.
12. Shades:
13. Cellular or honeycomb shades provide insulation and can block sunlight effectively.
14. Roman shades made of thick fabric can also be an excellent option.
15. Exterior Awnings:
16. Install exterior awnings to block sunlight before it reaches the windows.
17. Retractable awnings offer flexibility in adjusting sunlight levels.
18. Solar Screens:
19. Solar screens are mesh-like coverings that can be installed on the outside of windows to block sunlight.
20. They reduce heat and glare while maintaining visibility.
21. Shutters:
22. Interior or exterior shutters can be closed to block sunlight.
23. Adjustable louvers allow for control over the amount of light entering the room.
24. Tree Planting:
25. Planting trees strategically outside the windows can provide natural shade.
26. Deciduous trees with leaves that provide shade in the summer and allow sunlight in the winter are a good choice.
27. UV-Blocking Window Treatments:
28. Choose window treatments specifically designed to block UV rays while still allowing visible light.
29. This helps protect furniture and carpets from fading.
30. Double-Glazed Windows:
31. Consider upgrading to double-glazed windows with low-emissivity coatings to reduce heat and UV penetration.



When choosing a method, consider your specific needs, the direction your windows face, and the aesthetics you prefer. A combination of these methods may provide the best results for your situation.
