Good advice! Would you leave a gap between the drywall and the radiant material? The north side of my house is VERY cold and needs some help!

@@SheenaRea I haven't, because I haven't seen the need. They are outside walls but on the inside of the existing lath and plaster, and I don't have to worry about moisture. Now, if it was a basement wall, or a place where moisture can accumulate easily, I probably would. I have even used the foam-core radiant barrier on the floor of my basement under the rug. I can be barefoot down there and feel no cold from the concrete floor at all. My basement is partially fully finished and the walls were insulated when that work was done before I bought the place. So the only thing I do there in the winter is just tack up a run of it behind me where I sit and I use one of those oil-filled radiator heaters , so it just blankets me with warm! If I ever have to take down the drywall there for any reason, I would likely install some before I re-drywalled it. My boiler went out 2 years ago, and financial constraints have prohibited me from replacing it. So the only thing I have right now are the space heaters I use in the space I am in at the time. So I have the exposed foil hanging behind me , but I can roll it back up and use it again next year. Hopefully I will have regular heat by then! But I keep it exposed for maximum effect right now. But t discovered how usefull it was when I saw how COLD the walls behind my radiators were, even when they were pumping the hot water through. I LVE my radiator heat, and I love these old monster radiators, but thought there must be massive heat loss right behind them through those outer walls. So I just inserted regular tin foil behind them to see if it made a difference, and WOW, it sure did. But it's really thin and not made for that, but was a good tester. So I bought a roll of the radiant barrier and cut pieces to completely cover the walls behind them, and left it uncovered because you couldn't see it anyway. Girl, I swear, I had to turn the thermostat down 10 degrees after that, and that is aLOT. For the first time, I actually felt it RADIATING away from th walls. In the dining room, I experimented with putting a little fan from an old computer tower on the floor blowing up into the fins of the radiator, and that pushed the air further into that room. It was a great hack. Not one I could use everywhere, just because I didn't have power sources close enough and the idea was to conserve money, not revamp my house to accommodate a computer fan, LOL. But get this! My bedroom actually has 13 windows in it, It's like being in a treehouse in the summer! I love it. But I burned my eyes one summer while installing a cobblestone sidewalk up to the front stoop, using crushed lyme as a base. The dust got in my eyes and I nearly lost my eyesight completely. But the pain from just the sunlight coming through the windows was excruciating. I could barely have them open at all, it was a nightmare. So I had some of the thin radiant barrier, the kind that is more like mylar, and put it up over all the windows, and it was just the filter I needed, It lets in light but very filtered light. You can't see outside through it, but no glare gets through it at all. I was able to be awake WITH my eyes open, It was a two year recovery from that so I am so grateful for that product, I don't know how else I would have gotten through it! AND, it keep out the unbearable heat in the summer! I would highly recommend using it behind curtains in the summer for heat coming through. But the wider size as opposed to the narrow and more seams is the way to go! Also, I don't buy mne at the regular home improvement stores, I order it online. It's around $80 to $120 for 48" x 250'. That goes a long way! Shop around, prices do vary.

Mold is a definite problem for using the bubble wrap on an interior wall

That Idea kinda reminds me of Tapestry they put up on walls in Castles back in the day, lol

😂😅

No not at all! I checked it after a year no issues👍
