ENERGY STAR certified
This interior compression window is ENERGY STAR certified for the Northern climate zone. The EPA estimates that certified low-e storm windows save homeowners about $350 a year, roughly 10 percent of heating and cooling bills, over single-pane clear glass windows without existing storm windows, and that the extra cost pays back in about three years.
Certification is listed model by model, so it applies to this window and not to every interior style we sell.
The EPA calls these estimates conservative. Actual savings depend on your climate, your home and your utility rates.
What does ENERGY STAR certified mean?
5-year limited warranty
A 5-year limited warranty covers defects in materials and workmanship. Fading and warping of dark brown vinyl in intense sun, and glass breakage, are not covered. The manufacturer repairs or replaces a defective window at its option, and shipping costs are the owner’s.

Our storm windows and storm doors are produced in the USA, made to order for the opening you send us.

Glass or acrylic

Compare glass and acrylic options

Clear glass: A transparent glass panel for a clear view.
Low-E glass: Glass with a coating that reduces heat transfer.
Acrylic: A lighter plastic panel. It needs gentle cleaning because it scratches more easily than glass.
Tempered glass: Safety glass that breaks into small pieces.
Tempered Low-E glass: Combines safety glazing with a heat-control coating.
Laminated glass: Glass layers bonded around an interlayer that helps hold broken pieces together.

The window is close to a door or floorCheck this if the glass is within 12 inches of a door or 18 inches of the floor. These locations require acrylic or a suitable safety-glass option.My opening has an unusual shape or fitCheck this for a bowed sill, uneven corners, obstructions, or a shaped opening. These details need review so the panel fits correctly.I need a dividing bar or an additional exterior screenA mullion is a bar that separates multiple panels in one opening.

Compression Fit

About this storm window

A removable vinyl-framed interior panel that seals inside the existing window stops. Preserve original windows and reduce drafts with a compression fit that accommodates modest variations in the opening.

Benefits

Removable single panel

Concealed stainless-steel springs hold the panel within the opening without a continuous perimeter track.
Remove the panel from inside the room for cleaning or seasonal access. Plan a safe storage location before removal.
Measure all four sides at the mounting plane. Record out-of-square corners instead of averaging the dimensions.
Mounting depth: 3/4 inch; shallower openings need review

Why you'll love it

Keeps your original windows in place
Made to the dimensions you enter
Backed by our lifetime limited warranty

Product specifications

Mounting depth: 3/4 inch; shallower openings need review
Operation: Removable single panel
Frame colors: White, Almond or Brown
Glazing: clear, Low-E, acrylic or safety options

What's built into the frame

Compression fit. Concealed stainless-steel springs hold the panel in the opening without a perimeter track, so there is nothing to build or fasten around the window.
Fits openings that are not square. The spring fit adjusts to openings that are slightly out of square, which is common in older homes.
Simple, tool-light install. The panel sets in from inside the room with no carpentry, and comes out the same way for cleaning or seasonal storage.
Durable vinyl frame. A vinyl frame made to the size you enter and mounted on the room side, so the outside of your home looks the same.
Glass options. Choose clear glass, or add Low-E, tempered, acrylic or laminated glass for energy performance, safety or UV protection.

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.
