The federal Energy Efficient Home Improvement Credit ended for property placed in service after December 31, 2025, so there is no current federal credit for windows. Some utilities, states and local programs still offer efficiency rebates, and many ask for ENERGY STAR certified or AERC-rated products. Programs and amounts vary, so check with yours before you buy. We cannot promise any specific rebate, but we can supply certification details for a model on request.

An insulating glass system mounts over the window you already have, and the still air between the two windows is the insulating layer; the added glass is typically Low-E coated. An insulating glass unit (IGU) seals two or more panes together at the edge, usually with gas inside, and is part of a replacement window. A system has no sealed edge or gas fill to fail, and your original window stays in place.

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.

White, Brown, Black, Custom color. Choose the color on the product page after you enter your measurements.

It mounts on the exterior. Uses a two-track aluminum frame with a full-size removable sash and screen.

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.

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.
