Retrofit Cellulose Insulation In Walls Of Older Homes

Cellulose Answer Man: Your Source For Information

Timmy asks:

I am a building maintenance teacher in southern WV. My students are going to exit my class in an area of a lot of old homes that do not currently have insulation in the walls. I know that blown in insulation can be an easy product for them to use in that space, but I don’t have the most experience with blown in insulation. I have a couple homes I would use this product in myself. I would love to have an expert come in and give my students a presentation on cellulose insulation!

Answer:

Thanks for your interest in cellulose insulation. There is info on our website about retrofitting walls with cellulose insulation https://cellulose.org/Cellulose-Insulation-2nd.php?pagename=Retrofit_Installations&dirname=HomeOwners. I suggest you search You Tube to start your search as well. CIMA producer member GreenFiber has a few videos linked from their web site. There is also a rather old publication written by a friend of mine 50 years ago. https://cellulose.org/GreenestInsulation/wp-content/uploads/2021/09/Two-Hole-DIY-Wall-Insulation-Retrofit-Guide.pdf. The two-hole blow method Roger describes in this piece is rarely used anymore. Common practice is to install insulation through a fill tube, as you will see on our website and in the on line videos. I am looking into a possible scenario that would let you observe insulation installation operations. If it can be arranged it would require a drive to Southeast Ohio, if that is acceptable to you. I will keep you informed.
