Choosing Vertical Storm Windows

Compare exterior vertical tracks with interior double-hung systems. Match the existing meeting rail and check whether your mounting space is inside or outside the primary window.

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

What makes vertical storm windows a smart investment?

They add a sealed air pocket over your existing window, which limits heat transfer, softens exterior noise, and extends the life of original sashes and glazing.

How do dual-rail and three-rail vertical storm windows compare?

Dual-rail units carry two panels and one screen, a practical, cost-effective choice. Three-rail units add a third track so you get two independent screens and finer airflow control.

Will vertical storm windows help with drafty older homes?

Absolutely. The perimeter weather stripping and mechanical interlocks close off gaps around aging frames, noticeably reducing cold-air infiltration.

Are these mounted on the inside or outside of the window?

Our aluminum vertical models are designed for exterior mounting, which keeps the protective air gap between the storm panel and your primary window.

What is the best way to measure for vertical storm windows?

Take width and height readings at three points across the opening, record the smallest figure for each, and reference our detailed measuring guide before placing your order.
