We got the impact window installation done last week, and it's already making a huge difference in our living room. The new polycarbonate panels fit snugly into the old frames, and the added insulation is noticeable—way fewer drafts. The installer was careful to seal all the edges properly, and you can barely tell they're not standard glass. If you're dealing with a loud street or worried about break-ins, this upgrade is a solid move. impact window installation 11
