About this storm window

A custom fixed storm window with straight sides and a smooth arched top, built for traditional architectural openings that cannot accept a rectangular panel. Width, total height, and springline height define the opening before final profile confirmation.

Benefits

Arch TopFixed GlassSpecialty Shape
  • Follows an arched opening while preserving the original window profile
  • Fixed glazing adds protection without obstructing the architectural shape
  • Custom springline placement creates a more accurate fit
  • Multiple finish and glass choices coordinate with the surrounding building

Why you'll love it

  • A tailored storm panel for arched windows in historic homes, churches, and distinctive façades.
  • The frame is built from your opening dimensions instead of adapted from a stock rectangle.

Product specifications

  • Custom sizes up to 36" wide by 72" high
  • Frame finishes: Mill (Silver), White, Tan, Bronze, Black
  • Glass options: clear, P62 obscure, or tempered safety glass
  • Fixed, non-venting configuration without a screen

What's built into the frame

  • Offset frame. The frame sits out from your existing window, leaving clearance around it and a layer of still air between the two windows.
  • Fits slightly out-of-square openings. A peel-type mounting flange lets the frame size be adjusted for an opening that is not perfectly square.
  • Flexible mounting gasket. A dual-density gasket around the mounting flange acts as a thermal break, reducing energy transfer through your existing window.
  • Powder-coated finish. A durable powder-coat finish holds its color.

How to measure

  • Record the full width, total height, and springline height.
  • Measure the springline where the straight side ends and the curve begins.
  • Upload an exterior photo so the shape and mounting surface can be confirmed.

Installation and care

  • Confirm the arch orientation and springline before drilling.
  • Fasten gradually around the perimeter to avoid pulling the frame out of shape.
  • The frame does not come with pre-drilled installation holes. Use the correct drill bit to make pilot holes, then fasten it with suitable exterior wood screws.
  • Apply exterior-grade caulk across the top and down both sides. Do not caulk the bottom edge.
  • Exterior storm windows have weep holes at the bottom of the frame so moisture that collects between your existing window and the storm window can drain out. Never caulk over the weep holes.

FAQs

What is the Arch-Top Picture Storm Window?

The Arch-Top Picture Storm Window is an exterior storm window made to the exact width and height of your opening. It fits a picture window or other non-opening window. It is a fixed storm panel that covers the opening without moving.

Does the Arch-Top Picture Storm Window include a screen?

This is a fixed panel, so it has no screen.

Which frame colors does the Arch-Top Picture Storm Window come in?

Silver (mill), White, Tan, Bronze and Black. Choose the frame color on the product page after you enter your measurements; the preview image updates to match.

How do I measure for the Arch-Top Picture Storm Window?

Choose how your window mounts: blind stop, overlap or window track. Measure the width at the top, middle and bottom and record every reading exactly as measured. Measure the height down both sides, stopping at the bottom of the drop on a drop sill or at the highest point of the sill on a standard sill. Do not add or subtract an allowance. We keep the readings for fit review and build only to the dimensions confirmed for the order. Our picture window measuring guide covers each step.

Which mounting method am I?

Look at how an exterior storm window would attach. If there is a blind stop, a narrow strip of trim set against the window frame, it attaches into the blind stop. If the window has flat casing around it and the storm would sit on the outside face of that trim, it is an overlap mount. If the window has a screen track the storm can slide into, it is a window-track mount. Choose yours in our measuring guide and the steps change to match; if you are not sure, send photos and we will tell you.

Do you add or subtract anything from the measurements I enter?

No. Enter every measurement exactly as taken. Do not add overlap or subtract clearance. We keep all readings for fit review and build only to the dimensions confirmed for the order.

Is the Arch-Top Picture Storm Window right for my window?

Choose a fixed panel when the window does not open and you do not need ventilation. For a window that opens, compare our two-track and triple-track styles.

Does the Arch-Top Picture Storm Window have weep holes?

Yes. Exterior storm windows have weep holes at the bottom of the frame so moisture that collects between your existing window and the storm window can drain out. Never caulk over the weep holes.

What affects the price of the Arch-Top Picture Storm Window?

The width and height you enter, the frame color and the glass you select set the price shown on the product page. Oversized openings may need a quote, and shipping and tax are calculated at checkout.
