@BOB24502 7 ай бұрын

I followed this method to insulate my basement walls & also insulated rim joists. It feels so comfortable now, the temperature is the same as the main level in my house, plus I cut my winter heating bill in half...I used to have a 5000W electric heater that would be on almost 50% of the time to maintain a mere 60 degrees in the winter. Now the heat pump alone is providing enough heat for the whole house for a fraction of the cost...

@gtarules1 5 ай бұрын

Where is the heat pump located that it heats the entire house and the basement? At 50% of 5000W, did it translate to 2500W used?

@BOB24502 5 ай бұрын

@@gtarules1 The heat pump is your normal setup, heat pump outside, air handler is in the basement. Ducts run through the floor between basement and main floor, and I have vents for both the main floor and the basement coming off the single air handler. Basement was un-insulated so yes, i would need 2500W on average in cold winter days to maintain the basement warm. I have a walk-out basement, so 3 walls are not under-ground, and 1 wall is. There was so much heat loss through the 3 walls that are not below grade. Just 8 inches of concrete block offer an R value of around 1.5. Now the R value of my walls is around 20 (foam board + batt insulation). Using a heat pump with 300% efficiency and insulated walls, the 2.5 ton heat pump is enough to keep the 2000 sq.ft. of space heated, i no longer need to use the 5000W shop heater. On cold winter months, my electric bill used to be around 3000 kWh. Now it rarely exceeds 1500 kWh in the winter. In my area where the kWh averages 16 cents in the winter, that equates to $240 in savings.

Do you think that would suffice for our harsh winters? Thanks and keep up the good work.

@HouseImprovements 2 жыл бұрын

That will work fine. Be sure your using R 14 minimum . 2x3s are too narrow for the Roxul depth but just frame the front edge of the framing out at 5" off the concrete and you should be fine unless your concert walls are really crooked or out of plumb then you may need to be out just a bit more.

@michaelbutler791 6 жыл бұрын

have a question about using rigid foam insulation in the basement. I am not going to finish the basement. I'm just trying to get some additional insulation on the concrete walls. When we get a ton of rain (several inches in a day or two) some water does seep into the basement . We do have a sump pump for draining our dehumidifier and so I can sweep excess water into the pump after heavy rain. My question is, should I leave a half inch gap between the foam boards and the basement floor, as oppose to, setting the foam boards directly on to the floor? My thought is this will better allow the water to come in so I can continue sweeping it into the sump after heavy rains.

I am buying a 1946 house where part of the cinder block basement has no house above it. Just a concrete slab which serves as a porch. I’m worried about that area being extra cold and having condensation issues. Would it make sense to glue the foam board panels on the walls AND the slab ceiling? Should I also add 2x4’s across the ceiling (attached to the walls) and staple paper faced batts up there? I’d really like to make the room into a usable a workshop for myself and not have to worry about moisture and mold.

I know this is an older video. I’m doing a reno on my lower level which is half block and the upper part is framed on the block. Funny thing is after I tore out the walls, all that was there was 3/4 of soft foam board between strapping with foil and the upper was bat insulation with the paper face and a paper over that covering the studs and painted wood panelling. No moisture or mold. Been like that for over 40 years. I’ll be doing some waterproofing from inside the house using the membrane into the foundation after it’s broken up. I notice hydrostatic pressure in the lower block. So I’ll be getting that fixed all the way around the basement on that third level. I’m in southwestern Ontario where it’s pretty hot and humid in the summer and the winters can be cold but are short. I’m going to use foam board along the lower portion of the block wall and then frame my walls after sealing up the foam board seams. I want to use Rockwool For the insulation in the walls. I may spray foam the upper cavities because it’s deeper And use Rockwool over that. I’m at a crossroads with the vapour barrier. I don’t wanna have any moisture problems. I just want to know if it would be OK just to install the Rockwool between the studs and then drywall over it and finish? I’ll be taking the time to seal all the cracks and crevices along the way. What are your thoughts on the vapour barrier not being used? I have a fourth level that has Rockwool in between metal studs and there’s no vapour barrier and have not had any moisture issues at all. That lower level is fully in the ground.

Hi Shannon - thanks for another great video. I love your channel! I agree with many of the other commentators on this video, the poly vapor retarder is a problem. Since the XPS insulation is also a vapor retarder, now you have wood framing between 2 vapor retarders. Any moisture in the plane of the framing is trapped and will eventually rot and mold the wood framing. Better to use 2" of XPS and leave the stud cavities empty. I have used this method before and had good results.

@HouseImprovements Жыл бұрын

1" foam does not have a perm rating that is low enough to be rated as a vapour barrier. It is acting as insulation and the moisture barrier in this position. Vapour barrier and moisture barrier are not the same thing. Some areas will even allow the use of 2" foam as the moisture barrier, I would advise not taping the seams in that case however.

You said spray foam would be better, I don't think this couple that had to have their roof removed in order to get rid of the dangerous foam would agree. I wish there were more videos on using rigid closed cell foam boards combined with bat insulation as that is what I am thinking about doing and if something goes wrong it is easy to remove. For me I am trying to insulate a garage with a room above so thinking 2" rigid foam sealed around with spray foam from a can to stop air flow then followed with bat insulation. Being the rigid board would stop moisture I would not think I need to add any type of water barrier like house wrap at the garage side, but these are the things I would like talked about in a video. I am not sure if water vapor that comes from the garage side through the Sheetrock then the bat insulation and then stopped at the rigid board is an issue or not. On the inside I would think the AC dehumidifier affect would take care of any moisture issue, but again love to see these type of topics discussed on future videos. kzfaq.info/get/bejne/Zq6YaLCK253Qh5c.html

Could you adapt this method to sheath a house "from the inside" that had the sheathing ruined by a flood without removing the brick. Yes it would have to be held with adhesive, there would be cutting sliding pieces around brick ties, caulking etc, and a lot of taping in odd angles, as well as things that would have to be done to give it more structured support,but I think it could it be done. The reason I ask is I have heard flood insurance polices are paying for homes built with older gypsum sheath, but they are only paying out a small amount. they don't want to pay to have all the brick removed, they pay for a method that uses a tar paper looking sheet and its screwed to the studs then a spray foam is sprayed, it is either cut to slide between brick ties or new replacement ties are put in that don't look safe, It also seems they leave the studs exposed with no moister barrier. I am afraid this is what they are going to try to sell me on, if these boards are flexable enough and light enough they seem better.

Hope your surgeries were helpful, and that you're doing well. As for your questions... You've probably completed this long ago. But, for what it's worth, there is a variety of very good advice in the thread above. The answer always begins with where you are. In BC there is of course a wide range of climate variations. In essence, the conclusion that I've come to (in southern Ontario) is likely 1.5" foam with joints taped and foamed to create a monolithic seal; then Roxul in a stud wall; then straight to drywall. Membrain by CertainTeed, as noted by some others, may make sense in place of a poly before the drywall. As I've read elsewhere, lastly, paint the drywall with a latex vapour retarder primer.

Are you adding a fire break on top of your foam. Looking for a video on how best to accomplish that.

@HouseImprovements 7 жыл бұрын

for me the floor above is the fire break but your code could be different. Come to my forum and we can discuss options there. www.house-improvements.com/forums/

@dksinger3317 7 жыл бұрын

I ran across similar situation - needing firebreak at top of 1.5" foam board. I ran my ceiling drywall all the way to the mudsill (or at least within a 1/2"), then applied bead of fire-rated expanding foam around the perimeter to fill in any gaps. While the drywall I used was not "fire rated" variety, it passed muster with my building inspector in providing needed fire block. On a similar note, our local code (Portland Oregon) requires periodic VERTICAL fire blocks when applying rigid foam board if there is going to be electrical installed in wall. I am thinking this could be a PT 2X attached to wall at req'd intervals, but this would be source of insulation gap and pot'l for moisture intrusion - Perhaps could cover with sticky window flashing (??).

I love watching your videos! I have a drain tile system in my basement, if I were to use foam boards on my walls, would I put it right on top of my drain tile? I’m worried that it will block water if it ever comes in to find its way to the drain tile system? Thank you for your help

@HouseImprovements 2 жыл бұрын

Just stop the foam a 1/2" or so off the floor and dont seal the bottom.

Love this video and this is exactly how I'm doing mine. However, the customer service team at Owens Corning is telling me to not use Poly because the 1in foam board already provides a vapor barrier and using Poly will create a second vapor barrier. Do you know anything about this?

Shannon's videos are great! But you're right Kyle. Adding that second layer of vapour barrier does trap moisture. You don't want two layers.

@HouseImprovements: You said the rigid foam is a vapor barrier, but then you also mention toward the end that you need the plastic sheet vapor barrier over the batt insulation. I thought I read somewhere that you shouldn't have multiple vapor barriers. Is there a risk of condensation in the batt insulation?

@Ahnen03 4 жыл бұрын

I think the rigid foam acts as the moisture or vapor barrier, whereas the plastic sheeting acts as an air barrier. Makes me wonder now as well....?

Thanks so much for your videos/channel, I'm a new subscriber. We just moved to a cottage in NB. It's insulated, but I don't think to code. The basement is poured concrete, all open, and we want to insulate (ourselves) and frame out 4 rooms or so. I got a quote for spray foam today (4k for about 900 sq feet)...eek. I've priced the foam board (Foamular) and pink insulation at Home Depot and it's a lot less than the spray foam...just wondering, what kind of wood do you use for the framing? Also in an earlier video, you mentioned vapour barrier under the floor plate (so the wood doesn't touch the concrete)...if you use pressure treated wood, do you still need to put a vapour barrier under the floor plate? Thanks so much!

@HouseImprovements 4 жыл бұрын

You can use a PT bottom plate and regular lumber for everything above that. No barrier needed between the PT plate and concrete. Make sure any fasteners driven through the bottom plate to hold studs or fasten plate to the floor are ok to use through PT lumber . they will be designated as ACQ approved.

Are you sure about putting vapid barrier against the wall (the Styrofoam), and "visqueen" plastic on the room side, how would moisture between the two in the bag insulation get out? Everything I've read/ seen says one side should be open to breath and allow moisture to escape otherwise rot and mildew develop? If you use EPS board you get an insulating board that can breathe.

Great video shanon... i always watch your videos and work on my house.....HI I am living in Northern USA near NY state. Just bought house and has cinder block foundation . House was built in 2007. I felt so cold in basemnet and first floor in winter when there is below 30 degree F. temperature outside. I am planning to insulate basement walls with this hybrid method. I am just done by insulating all rim joist with foam board and spray foam. Do you think by insulating walls wil give me any energy saving? if so then how much? Also wondering how i can insulate the concrete floor? could you pleas help me to do floor too. Thanks
