Tyler: As told in my talk with you, I was pleased that your inserts in two of my bedroom windows reduced noise from increasingly busy road noise to "no disturbance" status. All help previously suggested costly addition of another window in interior on top of existing new- build window OR storm window on outside of existing window. Indow inserts were cheaper, less obvious in room, could still see outside clearly, kept room warmer with additional air space between existing new-build window & Indow insert. Simply Indow insert solved my problem in that bedroom & my husband was able to measure & install inserts himself withOUT additional installer cost to us.
