Our upstairs bedroom was always freezing in winter, no matter how high we cranked the heat. Turns out the windows hadn’t been updated since the early 80s. We started looking into replacements and eventually went with Feldco. From the quote to install, the process felt easy, which was a relief since we were juggling other repairs too. The drafts are gone, and the room actually holds heat now. Has anyone used them for entry doors? I’m thinking of swapping ours out but not sure if it’s worth bundling with another project.
