  • 1.  Foam gun modification for better use

    Posted 07-01-2022 07:17
    I work for the State Weatherization office in Vermont WAP and part of our job is to share best practice or good ideas or new tools that an Agency has or uses, with the other agencies.  I was recently at an Agency in northwest Vermont, CVOEO Weatherization.  One of their crew guys had modified the standard single part foam gun to a more user friendly version (the can attached to the gun can often hinder the spots you can get at to foam).  The pictures are below.  Nate the crew person said the parts were less than $20 and it was fairly easy.  The foam gun is a lot easier to use and get to spots without the can sticking off the top of it.  Come to the Energy OutWest Conference in August in Denver and see this and other good ideas shared from around the country.

    add hose between the gun and the can for better flexibility

    Wow! Does the hose need to get replaced every time?  (just curious if the foam cures within it)

    Hi, no the hose does not have to be replaced.  Foam stays in the hose when not in use and does not cure.  If you are going to the Energy OutWest Wx Conference in August, the agency who developed this will be presenting it as a small part of a "Crew Idea" Sharing session led by Cal Steiner.

    Henri Fennell, a follower of BPA, asked me to post this comment for him:

    These one-part foam products are water-cured.  Choosing a hose that has the lowest possible permeability will make it last longer before it eventually stiffens up.  Look for a product like "Moisture Lok" rather than rubber.  These hose products usually have a poly or Teflon layer in the hose assembly to stop vapor transmission. 

    Great idea!
