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 specialty storm windows for distinctive shapes. 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, and specialty shapes—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.

Measuring and installation guides, with a team you can contact for help.

Our vertical storm windows mount over double-hung openings to cut air infiltration, dampen outside sound, and shield primary glass from the elements. Every unit is fabricated from powder-coated aluminum to your exact width and height. Pick a dual-rail model for straightforward performance or step up to the three-rail design for independent top-and-bottom ventilation and maximum weather protection.

Ideal Applications

Double-Hung Wood Windows

Vertical storm windows are the natural fit for traditional double-hung sash because the storm panels follow the same up-and-down movement as the original window.

Older & Historic Homes

Add insulation, weather protection, and quieter rooms while preserving original glass, trim, divided-light sash, and the character that makes older homes valuable.

Tall Sash Openings

Custom sizing keeps long vertical openings square and sealed, especially on stair landings, bedrooms, and living rooms where a standard insert will not fit cleanly.

Seasonal Ventilation

Two-track and triple-track configurations let homeowners balance winter glass coverage with warm-weather airflow through removable or adjustable screen panels.

Drafty Bedrooms & Living Rooms

The exterior storm panel creates a trapped air space over the primary window, helping reduce drafts, winter chill, and outside noise in rooms used every day.

Whole-Home Storm Window Projects

For homes with many matching double-hung openings, vertical aluminum storm windows create a consistent exterior look and a practical path to better energy performance.
