Explore installation optionsA non-operating fixed-pane unit built around a single sheet of 3/32-inch glass set into a sealed aluminum perimeter frame. Because there are no moving sashes or weather-stripped tracks, air infiltration drops close to zero, which makes this the quietest and most thermally efficient option in our catalog. Best suited for stairwell openings, gable-end accents, transoms, and any window where ventilation is handled elsewhere and you simply want a second insulating layer at the lowest possible cost.
Benefits
- Adds a protective glass layer without changing the original window
- Helps reduce drafts, outside noise, and seasonal heat transfer
- Clean, stationary design for picture windows, transoms, and sidelights
- Removable panel makes cleaning and maintenance straightforward
Why you'll love it
- A simple, cost-conscious choice when ventilation is not needed.
- Slim aluminum sightlines preserve the view and the character of older openings.
Product specifications
- Custom sizes up to 72" wide by 72" high
- Frame finishes: Mill (Silver), White, Tan, Bronze, Black
- Glass options: clear, P62 obscure, or tempered safety glass

How to measure
- Measure the opening width at the top, middle, and bottom.
- Measure the opening height at the left, center, and right.

Installation and care
- Confirm a flat, secure mounting surface before ordering.
- Fasten evenly around the perimeter and seal only where your installation method requires it.

FAQs
Can I keep my existing windows?
Storm windows are an additional layer for existing windows. Check that the primary frame is sound and address rot, leaks, or other damage before adding a storm window.
Which opening style should I choose?
Match the way you use the primary window: vertical operation for double-hung openings, horizontal sliders for side-to-side operation, and fixed panels where ventilation is not needed. Confirm clearances before ordering.
What affects the price?
Dimensions, glass, frame finish, and configuration affect product pricing. Oversized openings and specialty details may need a quote. Shipping, tax, and installation are separate.
How should I measure an older opening?
Measure each opening at the intended mounting position and keep readings from multiple points. Record mounting depth, obstructions, and any out-of-square conditions. Follow the guide for your selected product before confirming manufacturing dimensions.
Can I get help with installation?
Review our installation information or contact us with photographs and measurements. Homeowners can request a separate installation quote; availability and project requirements need to be confirmed.
