Choosing Low-E Interior Storm Windows

Check the room-side mounting depth, handles, and blinds before choosing a compression, surface-mounted, double-hung, or sliding system. Match access and ventilation to how you use the room.

Start with where your storm window will mount and how your existing window opens. Explore interior storm windows for an inside-mounted layer, exterior storm windows for fixed or ventilating openings, or Low-E storm windows for additional glazing options. Check the mounting requirements and use our measuring guides before ordering.

What affects the price?

Dimensions determine the size of your frame and glass. Glass options, frame finish, and configuration (including fixed or operating panels, track count) also affect the price. Configure your chosen product for available pricing, or request a quote for details that need review.

FAQs

How do low-e interior storm windows mount?

Check the room-side mounting depth, handles, and blinds before choosing a compression, surface-mounted, double-hung, or sliding system. Match access and ventilation to how you use the room.

Can I still open my primary window with an interior storm installed?

Operating double-hung and slider systems provide access through movable panels. A compression panel may need removal. Choose based on how often you ventilate the room and where you can store a removed panel.

What interior clearances should I measure?

Check usable mounting depth, handles, locks, blinds, and the space needed to position or remove the panel. Follow the selected system’s measuring guide and retain every reading.
