You should use the Tica T500 premium outdoor sealant for windows, as it is exposed to rain and wind. This will ensure the windows are sturdy and durable
Tica Silicone T300 provides excellent waterproofing performance. However, if cost savings are a priority, you can opt for Tica T100 or Tica T200. Please note, though, that their durability and long-term water resistance are not as strong as Tica T300.
