Foam Insulation

[414Gianna]

could you use the ridged dry to fill cracks on floating docks or boats so they don't leek?

[azthundercloud]

i have a few skylights that wre not insulated. can this product be used to fill a 36in wide by 24 in tall by 3in deep area? i deaed going in there to stsaple insulation as it is a pain to get to these areas

[AsktheBuilder]

@azthundercloud Why not used rigid foam to within .5 inch and then the foam from the can?

[panddjensen]

well, didn't think of it that way..thinking more along the lines that these types of products had a certain temp range to them, kind of like painting which you can only do in certain temps. Guess I will give it a go!

[AsktheBuilder]

@panddjensen Correct. That explains my first reply to you. That's precisely why I said to look at the label. We're now on the same page. I had the same fears you did. That it was temperature dependent.

[panddjensen]

I live an hour away from the store so I was trying to do some research before wasting gas and money if I wasn't going to be able to use it. I did go to Great Stuff's website and there wasn't a thing I could find on temp. I tried calling them and was put on hold for a long time so I tried researching it online and that's how I came across your YouTube video. I figured you prob had alot of experience with it and it would be a pretty easy question.

[AsktheBuilder]

@panddjensen It would be an easy question if I was able to memorize the label instructions for the tens of thousands of products out there. My guess is that when you don't see any temp ranges on the label of the product, then you can use it at any temp that you can work in. Go for it.

[panddjensen]

Thanks for the video! Can you tell me what temp it has to be inside the house in order to use the spray? We live in VT and it only gets to a high of 35 degrees right now. Is that too cold if I kept the bottles in a warm car before using them?

[AsktheBuilder]

@panddjensen When you read the instructions on the cans and went to the manufacturer's website, what did you discover? I'm sure you did that before writing your comment, right?

[mrjost55]

This stuff dries inside the tube, so it's basically a one time use bottle, unless you can find another supply tube or you can clear the old one out.

[fishmeer]

Heavens to mekatroids batman,He's destroyed the sacred contracting shirt....lol!

[AsktheBuilder]

@fishmeer It wouldn't have been so bad had in not been the FIRST time I was wearing it. Out of the wrapper no less than an hour..... :-<

[jingerfinger]

yes... wear gloves.

[AmazingFoamInsulatio]

For about $40 you can be a foam applicator gun and use 20-24oz can. Just shut the gun off and reuse many months later until can is empty then put new can to use.

I've always have been told to use organic filter. Why does "Great Stuff" not have any safety warnings? One "hicup" inhaled will be fatal. Cover up and have someone else talk or vicversa.

[penopolyuretan]

Не понимаю, а что мешает заклеить окна малярным скотчем и переодется? Тоже мне открытие сделали: "Наша монтажная пена, сохраняет гибкость после отверждения"

[RJH33101]

If you pull the applicator straw off right after use and stick a wire hanger through it when it dries you can pull the foam out. It does not stick to the plastic straw for some reason but it does stick to the hanger. Once you break the product seal by useing it, it will have a short can life and harden inside the can. Shake well before use also. I have never heard the mixing ball rattle like it clames on can but have had good results.

[RJH33101]

Cover your floor right to the wall ! This stuff will expand out of the crack that your filling and drop to the floor. Most of us will over fill and when it cures you can cut it away from the crack but if it hits the floor it will be very hard to clean up the floor!

[undergroundbasement]

Yes, I do love that canned foam insulation , but you may as well use up the whole can once you start using it , because it will dry inside the applicator straw that it goes through rendering it useless when you go to use it the next day or week or whenever

[catfish4975]

Christ Almighty, that was a sweet shirt you ruined Tim.

[AsktheBuilder]

It was the second time I'd worn it. A great one from LL Bean.

[Soythane]

My friend, forget the shirt, you should have wore a minumum of a charchol resperator.

[AsktheBuilder]

Thanks for the great suggestion. Now I have to figure out how to talk through it as we record the video. :->

[tanerofies]

Wear a hat, or anything that'll cover all your hair, as well if you're working overhead. You do not want to get this stuff in your hair.

[DukeShelton]

Bees cant burrow through foam, and have NO desire to. They always take the path of least resistance. Insecticide is NOT necessary, bees will simply adapt and go another place or direction.

[fai1saf3]

lol he ruined that route 66 shirt

[massergiomusica]

Aww...thats so sad..poor shirt ='[

[Slaughter619]

OMG! SO EXSITEING!!!!

[rubber314chicken]

where the power line enters our house, we have ants entering? Would this be a good solution to block them? Along with some Raid for ants?

[AsktheBuilder]

Yes and yes. Go to my buddies site: AsktheExterminator and read about ants.

What do you think of spray foam roofs? I need a new roof and I'm torn between redoing the flat roof the traditional way or there seem to be several options that can go right over the old roof. Not sending a truckload of waste to the landfill is appealing.

[AsktheBuilder]

I'm studying them.

[Michalbasavraham]

I used to work for a roofing company. One thing I picked up is that the max roofings you can do is 3 layers, usually, though, two is the max. Do you know how many layers you have up? Also, more layers actually make the roof more prone to leaking.

[Oehtkralc]

Thank you for your reply.

[Oehtkralc]

Hmm... I wonder if this stuff would be good to seal the opening of a large metal tube that bees have made a hive in. That is after I try to get the bees relocated. I'm trying to keep them from coming back and from rodents from gorging on the bees leftovers. Wonder if it's weather proof in Southern California - no snow.

[AsktheBuilder]

Bees could excavate through the foam in no time.

About the "voided warranty" issues,,, it is as with a lot of other products that are given warranties,,, these companies are always looking for a "reason" to NOT honor their product warranty,,so they put the BLAME on either the customer, or the installer, or if another product is used in conjustion with theirs. EVEN IF the other product is "proven" to be ok to use. Warranties claims are almost always immpossible to cash in on. It's a shame, but true.

[AsktheBuilder]

I have to disagree. I know many companies that stand by their warranties. If you install a product according to instructions, keep the written warranty and then make a valid claim, only an insane company in this day and age of the Internet and social media would void it. Something tells me your experience may be from situations where the company had a valid reason to void the warranty.

[Wateree2007]

I like the stuff but it is pretty messy to use. I am sealing duct and cable entries from my crawlspace. You cannot hold the can upside down, after sealing 3 holes the tip gets all messy and the stuff drips down.

You cannot keep it clean because as I understand only acetone will remove\clean this stuff.

[akzceiws]

I like the stuff, but after using it, the tube clogs up. Does anyone know how to keep it clean for future use?

[AsktheBuilder]

I believe there are instructions on the can that give suggestions.

[Aristera]

A warning for all. Every can of spray foam I've used needs to be held upside down in order for the spray to work properly. Otherwise you just release the propellant and then the foam won't come out and you need to buy another can. I'll give Tim the benefit of the doubt that that can uses a different propellant and he's using it correctly but as Tim says, read the directions for correct use.

Oh yea, the only thing worse then spray foam on your skin is roofing tar. Wear gloves.

[Tammij89]

yes some have fire rating i know everbuild makes one called firefoam

[allenellisdewitt]

Question: I know (from past experience) that it's extremely flammable while installing: Is it still highly flammable after it has cured? Thanks!

[AsktheBuilder]

I am quite certain that some types are. There are foam products that do have fire ratings. They are used as approved fire blocks around pipe, wire and duct penetrations in wall plates.

[Nismoke]

They are still flamable after they have cured.if caught on fire they stink like toxic thing and burn for 3-4 seconds in each spot.then the fire stops.its not so easy though to set it on fire

[Tmeyer2005]

Hello, I am a warranty service tech for a large window company. Are you aware that using foam insulation around our vinyl windows will void your warranty for any problems in the future?

[AsktheBuilder]

I am not aware of that. Why would the new foams void the warranty? They are now flexible. The old foams were indeed a problem, as they cured hard as a rock so to speak. The new formulations are made for doors and windows. Is it time for your company to re-evaluate the new foams? I wonder.....

[Tmeyer2005]

I understand your position, and after talking to my supervisor, our company has not made any adoption of foam insulation in the installation method. Our warrranty simply states that no foam insulation can be used otherwise the outcome will be a voided warranty. I understand what you are saying. But getting our R and D department to adapt something and change warranties is a little more difficult. I just thought I would give you a heads up.

[Pivotmastor]

Wow Thanks i tryied that on my new house its fabules!

[AsktheBuilder]

You are most welcome. Be sure to use the flexible one for doors and windows.

[dtm2468]

Tim, great video and tips! Just had my place remodeled by a contractor, I don't think they used spray insulation. I know to use it for the future. Thanks so much.
