Storm Window Benefits

Choosing Exterior Storm Windows

Exterior storm windows mount outside the primary window. Compare fixed, vertical, and horizontal styles, and check the condition of the mounting surface, drainage, and installation access.

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

How much do custom storm windows cost?

Starting prices appear on each product card. Your final product price depends on dimensions, glass, finish, and configuration. Select a window to price your options; oversized or specialty requests may need a quote. Shipping, tax, and installation are separate.

Should I choose interior or exterior storm windows?

Interior storm windows mount inside the home and can preserve the exterior appearance. Exterior storm windows add a layer outside the primary window, with fixed and ventilating configurations available. Compare mounting space, access, operation, and the condition of your existing windows before choosing.

How do I measure older windows for storm windows?

Measure each opening separately at the intended mounting position. Record widths and heights at multiple points, along with mounting depth and any hardware or obstructions. Older openings may be out of square, so keep the individual measurements and follow the guide for your chosen window. Have irregular openings reviewed before ordering.

Which storm window type fits a double-hung window?

Vertical two-track and triple-track storm windows are designed for openings that move up and down. Compare the number of glass and screen channels based on how much ventilation flexibility you want.

When should I choose a horizontal storm window?

Choose a horizontal slider for an opening that is wider than it is tall or where the primary sash moves side to side. Confirm the operating direction before ordering.

What is a fixed picture storm window used for?

A fixed storm window adds a protective exterior layer to a non-operating opening such as a picture window, transom, or architectural accent where ventilation is not needed.

What should I do before ordering a custom storm window?

Identify how the primary window operates, measure the opening at multiple points, review frame and glass options, and read the installation requirements. Contact product support if the opening is irregular or unusually large.
