Had my crawlspace encapsulated in NC. I arranged to have rockwool comforbatting placed into the extended walls rather than fiberglass. Rockwool comfortbatting is moisture permeable, bugs and rodents hate it, sheds water, fire resistant, higher r value per thickness than fiberglass, and has sound dampening properties. Other than a lower price, the benefits of fiberglass is a fairly short list. My crawlspace problems extended from fiberglass, so I made it a point not to reintroduce fiberglass back into my crawlspace. I can't say I benefit of sound proofing, thankfully the fire resistance hasn't been tested, but floors are warm and the wildlife issues I was having hasn`t returned.

Question: I am adding foam board to the crawl space wall. There is fiberglass batting between the joists at the sill plate. should I continue the foam board up to the flooring or stop at the sill plate? Thank you
@CrawlSpaceNinja

I would stop at the sill plate and maybe lower if your area requires a termite gap then you could start again at the rim joists and foamboard/air seal there. Many pest control companies don't like the sill plate to be covered for termite warranties. Hope that helps, thanks for watching.

Just to check :: if issues with crawl space fiberglass insulation, replace if it’s vented. If not vented, I can remove so fiber glass insulation? ( it’s pretty rough looking )

Hey Michael, I've been watching your videos for almost 2 years now as well as those of others. You've made me realize things I'd never thought of before SO MANY times! I must say, without any hesitation, that you've got to be the #1 crawl space expert in the U.S. (shoot, maybe worldwide (seriously)!). Your information makes so much sense, is so thorough, and is easy to understand because you explain things so well - nobody else does all that anywhere near as effectively as you do. Your personality come through also, which adds credibility, and it's easy to see you are a smart person. I hope you're keeping local copies of all your videos "just in case" because they represent a valuable body of knowledge that can't be found anywhere else! As a point of reference, the formula I've used to sort out the "best" people to do business with includes these four guidelines: 1. They CARE about doing their job well and meeting the needs of happy customers. 2. They know their particular job well. 3. They are competent as individuals. 4. They have high ethical standards. You demonstrate each of these in great abundance - especially nice to see because it's so rare these days. My sincere thanks for helping me understand crawl spaces so well! Mine went from water, moisture, mold, and critters to dry, clean, sealed, and properly insulated thanks to you. Best wishes for your continued success (and more videos, please!)!

I'm building a house right now in CT. This information's value is immense! 500 square feet of pre-existing house (really a summer cottage turned into a year round dwelling) that had a whole host of problems. My wife and I replaced all the sills (with sistered 2x8s) to unitize the structure, lifted it an average 6 inches and put it down on poured columns. Right now we're adding the exterior crawlspace insulation ('skits') and intend to encapsulate the space using 10 mil (or better) using the techniques you've outlined. Still going to add joist insulation on the bottom of each bay (spray foamed in faced iso with fiberglass or rockwool. New England be *cold!* ). It's a lot of work but we're blessed to start with a near-clean slate in choosing the correct crawlspace components! My heart goes out to all those effected by poor conditions in their castles. I hope you continue making people's live better and healthier! Thank you.

Great video and information. I can see you want feedback to make the channel the best resource for crawlspace search results. I can say with confidence backed by my subjective experience as I explore the topic, you sir are the authority. I bet you have forgotten more stuff than other channels share. Now it’s just a matter of attracting the attention of viewers. My suggestion would be to grow or capture a colony of gnats so you can study their attention span. You have 4 seconds of undivided attention unless what you offer is necessary for sustaining life, such as light. Get right to the point. Viewers know in 2 second if they intended to be here or not. Don’t waste your precious time on training people about KZitem. You have too much gold to share. It would be like having a key note speaker charging $10,000/hr spending the first 5 minutes explaining where the bathrooms and fire exits are located ;) Video. How many words are represented in a 30sec video? 30,000? Do lots of them. Capture raw emotions. Show the worst of the worst so they come see your channel.

If it is trapping moisture, it can be a problem. Your type of construction is difficult to insulate properly and keep dry. You may want to consult a local contractor or weatherization specialist that understands moisture prevention.

What do you recommend for insulating skirting of manufactured home in zone 6/7? Typical home comes with fiberglass insulation with "belly wrap" vapor barrier under flooring with home installed on a concrete slab. Skirting is often uninsulated although we are seeing more installations with insulated skirting (foam board which look like stone or brick). Uninsulated vinyl skirting typically includes sections with ventilation. New installations with insulated skirting usually include multiple automatic vents. Seeing people insulating skirting of manufactured homes and not installing any ventilation and covering what ventilation may have been present. When this is done I rarely see any dehumidification installed. Seeing damage from excess moisture when skirting is insulated with no ventilation, or very little.

Wow, that's a cold area. I am not familiar with codes in that area but if Tennessee requires an R10 with 8-inch block minimum and a skirt offers zero protection versus a block wall. I am guessing, again guessing, I would want at least R20 if it were my home. Since usually foamboard is R10 max, I would double it up. That may prove to be a tough job but may be easier than installing a permanent foundation. Sorry I don't have a better answer...thanks for watching.

To secure the vapor barrier, is it better to tack it down with gravel on top along the perimeter or tape it to the concrete wall? I think tacking it down with gravel (or sand bags?) is better as the concrete wall breathes and the condensation gets trap and causes the tape adhesion to fail. Appreciate any thoughts.
