Time to soundproof the windows in my basement. They are 17" H x 34" W, single pane, wood frame, with a thin sheet of plastic about 2" away on the exterior to make them translucent. Seems like they are a weak link compared to the stud wall and concrete right next to them.
How would you go about soundproofing windows? And any experience/ thoughts/ insight on these methods, assuming proper sealing and airtightness:
Wood plugs, essentially a solid core door for the window. Advantage: cheap, easy to build up layers for thickness/ mass. Disadvantage: no more natural light (which can be cured with a hinge).
Sheet of acrylic mounted on an extra frame on the interior. Advantage: passes light, about 2x as dense as wood, can be built up from small layers. Disadvantage: cost, especially as the thickness of the sheet increases.
Additional glass mounted in an extra frame on the interior. Advantage: passes light, about 4x as dense as wood. Disadvantage: possible breakage, costly after 1/2" thickness.
Dual pane vacuum sealed glass (1/4" on either side) mounted in an extra frame on the interior. Advantage: passes light, 2 layers of thinner/ cheaper glass, air gap should help reduce conduction. Disadvantage: possible breakage. Believe it or not, a local glass house quoted me less for the sealed dual pane with 1/4" each side than for the single pane of 1/2", and it was about half of the cost of similar 1/2" acrylic.
