Question About Window Plugs
« on: August 18, 2006, 09:51:27 PM »

I have a construction project about to begin about 150 yards from my (rented) 2 story home. I am considering using 2" R-TECH as window plugs for the two 28.5" X 46.5" windows. Do you think this would help? As I live in Alaska blocking out light is a bonus.

Hi Wolf,

R-TECH is an expanded polystyrene foam board - it is for thermal insulation.  That material will do nothing to block out the sound from the construction project near you.

To make a window plug that WILL block out the sound, use 2" thick Super Soundproofing acoustic Mat.  For info see the first product listed at

This solution is discussed in detail at

And if you want a more versatile window plug, one that won't block the light (that's what curtains are for) and can be left in all the time, try a piece of 1/2" plexiglas.  A 4' X 8' sheet runs about $250, at least in the lower 48...

An alternate solution is to use clear MLV strips hung on a mounting kit directly over the window.  Overlap the strips 100% to enhance the sound reduction.  This solution will reduce sound by 13dB.
