Window Inserts for Odd-Shaped Windows

Do you have any arched, round or eyebrow windows? If they’re drafty, or if you need to create privacy or filter light, unusually shaped windows can prove challenging. It’s hard to find a replacement for unusually-shaped windows. And most storm windows come in squares and rectangles, nothing like the odd-shaped window that makes your house look so unique.

If you have an especially large window, you may need to introduce a mullion, which will divide your insert into more than one segment.

Indow’s custom-shaped window inserts are the perfect solution for blocking drafts in uniquely shaped windows. They can be cut to fit any form. Round, oval, batwing – you name it – Indow can create a specialty-shaped window insert that will block drafts and noise. Customize them further by getting them made in Privacy Grade to obscure what’s happening within or Museum Grade to filter damaging UV light, all without distracting from the window’s unique beauty.
