Interior vs Exterior Storm Windows
Exterior storm windows are the most common option for aluminum systems because they protect primary windows from weather and improve efficiency. Interior units can work well for specific historic or access-limited projects. Your best fit depends on window type, installation access, and seasonal performance goals.
Exterior Storm Windows
- Strong weather protection and draft reduction
- Common choice for aluminum two-track and triple-track systems
- Usually best for whole-home efficiency upgrades
Interior Storm Windows
- Useful where exterior changes are limited
- Often considered in preservation-focused projects
- Can simplify access in some multi-story settings
