  2. Consider your budget: Include window cost plus any blinds or flyscreens you’ll need to buy separately.
  3. Think about installation: Are you DIYing or hiring pros? Some windows require expert fitting to maximize performance.
  4. Decide on features: Integrated blinds and magnetic screens save space and effort—worth the premium?
  5. Size and placement: Choose window sizes that balance natural light and privacy for your layout.
