Insulation

18 posts in this topic

I just started to finish my basement (not going to hurry at all). The basement has fiberglass insulation non-faced throughout the outside walls. I was wondering what people thought of taking this stuff out and getting the foam/spray stuff.

Also between the ceiling and the upstairs floor should I put fiberglass insulation?

Thanks all!

We havent gotten to finishing our basement yet, however when we built 4 years ago we did the main floor. I used 6" fiberglass rolls in the ceiling because the living room is directly under the master bedroom. It not only keeps the heat on the floor that is heated, but also allows me to watch TV on "Normal" volume...with out the "can you turn it down?" speach.

We also insulated the walls between the laundry room and the bathrooms on the main floor and upstairs to help with noise. If I had the money I would have tried to do spray foam on all of it, but cant have everything.

ive been told that closed cell is better than the open cell, is it really i done know!!

so there is only really 2 kinds that are sprayed: open cell and closed cell. might want to do some research on the 2 to get the best choice.

If it is an old house just put fiberglass back in. I prefer the paperback. The gig is not really out on the foam. We will find in the future how good or bad it is. Makes remodeling in the future really tough. Old houses leak air new ones run the air exchanger, horse a piece. Have seen foam that did not adhere on a few occasions. Not much r value there.

I just remodeled the lower unit of my rental property last year (1950's bldg). I had the walls and rims spray foam insulated, WOW! The unit is vacant so I set the thermostat to 55 degrees, never gets there, the temp has stayed around 65 just from the heat from the boiler room and the unit above it. The foam really stregnthened the walls too, if I could have afforded it I would have sprayed the ceiling too (used batts). I say thumbs up if it is in your budget! just get a good contractor and check references.

A cheaper way and a little more expensive then batting would becall blowing insulation with a netting material its like blowing your attic except you blow it into walls, you attach the net to the studs then blow in the insulation gives yu a great r valuebut its a little more expensive then batting but way less expensive then foam spray, either way fom or blown in ar both really good R values.

MNwalleye - is that the stuff that you can do yourself; I noticed Home Depot has some stuff that you can buy - then rent the blower

I think they rent out the machine but you still have to buy the netting, I worked for a company called central insulation out of waconia, but yes rent the machine put up netting and blow, but you do know know you have to mix a little water glue onto the insolation to make it stick. but blowingit in shouldnt be a problem either.

    • Good question, why didn't they find any more?  Did those two infected deer parachute in?  Were they dropped by a helicopter?  I find it fascinating they could get as far as Lanesboro and they only find two out of thousands.  Like I said, they're bad at conspiracy.    Policing the borders?  How about a billboard, a radio ad, or a twitter campaign?  How about having the highway patrol pull over anyone with hooves or antlers sticking outta their truck box or laying on a flatbed coming across the border on the interstate?    My wealth and land ownership shouldn't disqualify me from questioning the DNR.  It used to be a staple of a free country to question your government.  Somehow now it's more important to kneel before the all knowing DNR and take whatever they want to shove in our mouths?  If this is real science and a real mitigation effort, let's have a discussion about it.  If the DNR wants to stop this spread, why are they not welcoming with open arms feedback like mine when it comes to import enforcement, and an effective PR campaign?  Cause guess what fella, lots of deer got hauled home from all kinds of places infected with CWD by uninformed folks that are going to cut up those critters and throw the brains and spinal cords out in the woods at home.    So yeah, this is either a giant hoax, or the DNR has no idea what the hell they're doing. 
    • I just checked on the fans that I bought, there 4.7 inchs sq and 1.25 thick. I thought they were 5 inch thick but I was wrong. They are 110v and I think I will put one inside on the bottom plate and see how it works. And I like where you have your fishingstar.
    • Slowly getting the outside buttoned up 
    • Yea I had that idea too 
    • I saw three or four huts in the little wet area in the lake vadnais area just off country road F.   But they would probably get upset if you set traps there...    right next to the new path that goes south along the east side of the lake. 
    • In the olden days, pigs were fed garbage.  Trichinosis was a problem.  Then laws were passed so any garbage fed to pigs had to be cooked first.  Problem went away.   According to CDC there hasn't been a case of trichinosis except from eating wild game like bear meat for many years.  
    • From a quick google search it looks like waveinn.com or the bay of e might be your best bets, if you don't want to buy from shimano.
    • Does anyone know of a place you can get spare Shimano Sedona spools?? I run braid in the summer and don't want to run it on the ice.
