CRUCIAL Garage Door Insulation Step Everyone's Unknowingly Missing! How To Install Properly

[@HowToHomeDIY]

Were you aware of the important tip I shared in the video? That alone can increase efficiency by up to 50% and it costs nothing! All of the tools and materials used in this video are in the video's description for your convenience!

[@4ziDahaka]

Have you done day temperature readings before and after? Curious how 10 degree less radiation heat translates to the overall garage temperature. Regardless, this is super helpful, thanks!

[@HowToHomeDIY]

@4ziDahaka well the main purpose of the insulation for me was because I added an air conditioner in my garage. So my readings now would be skewed.

[@bigoranget]

My house has a bedroom above the garage. We replaced all the batt insulation in the walls and ceiling with spray foam and put the polystyrene insulation in our garage door. That bedroom is now 7-10 degrees cooler in the summer and about the same warmer in the winter. We also wrapped our duct work with insulation and sealed the joints. I remember before we had that work done, you could feel the heat radiating off the floor in the summer.

[@alittlemorepull]

I did this 22 years ago a few weeks after moving in. Mine faces west so I figured something was better than nothing. Mine looks very similar to yours. Maybe I was expecting too much but my garage still hits 99 on a 105 day. Didn't think to measure the actual garage temp for a few days before installing it so I really have no idea how well it works. But, it does look nice and is allot quieter than before. Many people have commented on how quiet it is and asked what I did. Typical Texas summer day so just took a quick measurement like you did - which I'd not tried before - didn't have the tool back then. The inside metal surface is 129 and the board surface is 109 - it's 5pm. So in theory it is working I guess 😁 I'm not ABOUT to remove the panels now just to find out!

[@oldskule2091]

Great video again! Thx! Did this few years back. Also used white duct tape around edges to keep secure. Builder- DR Hor-ton- used cheap door & built door opening bigger than door- no kidding. Then had professional garage door guy come out to install more molding. He then discovered that builder used TWO DIFFERENT SPRINGS! Evidently they threw in what they had left on truck! He replaced with heavier duty springs & balanced them. Then I installed heavy duty belt drive opener & put up battery back up in case power out. Not cheap but glad it’s done.

[@robertjohnson4401]

I added metal tape to all of the edges of the insulation panels. The panels do not fit tight and the metal tape helps seal the heat from passing into the garage. Insulating the garage ceiling from the attic will help

This is the best garage door insulation vids on YT. You are excellent at explaining DIY processes. Thank you for your contributions. 🤝

[@majorburke9735]

I was unaware of these kits. I’m sure it would help as my garage door faces east. The comments helped me figure out what I wanted to do. Since my garage roof is not insulated, I have no exhaust fan, and bc my garage door has a lot of light on the edges, I think I’ll pass. Plus my garage door is old and may need replacing. I suggest people hang a 15-lb. weight on their door first; to know if it will have an issue.

[@stephenlea5765]

DIY install of both insulation and Vinyl Garage Door Stop Moulding was well worth the $ spent, especially down here in South Texas where the Summers are scorchers!

[@az55544]

I have boxes of denim insulation used for meal kits. Because they aren’t fire proof, i hesitate to use them as insulation. Because they contain bits of plastic, they can’t be recycled. Any recommendations on their reuse? (I have made a few cat beds from them)

[@tst7273]

Could you just use spacers between the door surface and the styrene sheets to ensure the air gap? I'm thinking about little cardboard shims, maybe...

[@HowToHomeDIY]

Absolutely! Cardboard, I think, would be a good choice!

[@foxtrottango8745]

A few years ago I had my ceiling insulation re-blown in and had them to cover the garage ceiling too which made a huge difference. I was going to cover the garage door but decided not to because we are selling soon.

[@UppsalaSal]

My garage faces due East so on summer mornings it becomes an oven. I installed foam insulation about 10 years ago and it seems it’s a bit cooler, and in winter retains the heat. I suspect the foam adds a bit of sound deadening. My doors are wood panels and don’t have the frame structure yours have, so I used fender washers and screws in the panel corners to tack the foam to the door interior.

[@daveedwards1257]

How about using reflectex . The bubble wrap that has tin foil on either side is something we were wondering about. Can you also do a vid on Reflectix ! Good helpful vid here thanks 💙☝️😇🌲🌲🌲🌲🌲🌲🌲🌲🤗

[@gregmgm06]

Excellent job on this video! Have you ever seen two layers of insulation on a garage door, such as an additional layer of Reflectix ? Our door faces south and gets beat to death by the sun. Im assuming it would help.

[@christhompson3655]

I used one of these kits on my garage door. Easy to install. I have a row of windows on the door so I put black window tint. Also since my doors face the east they get a lot of sun exposure, I put a layer of thin silver reflective roll of insulation on before it put the styrofoam. Only issue I had was the frame around the windows. It makes the styrofoam now out. I now have to do the double garage door.

[@sarahmyers102]

Hi. Appreciated your comment. Do the kits come to accommodate the windows in the door, or do I need to plan to cut for those too? Thanks!

[@christhompson3655]

@@sarahmyers102 it does not accommodate the windows. Depending on your door, if it’s just trim and not holding the window on the door, you can take it off. If the trim fastens the window to the door, you will need to trim out some of the insulation.

[@sarahmyers102]

I have a 16' garage door and my bottom seal needs replacement. Lizards in the garage and dirt blowing under. Can you recommend a product for this job? Thank you!

[@ryoung6725]

I did it like you said but I live in Illinois. The wind blew half of those frames out the garage and down the street, breaking into numerous unusable pieces. Oh well. Maybe I should have glued them in first?

[@HowToHomeDIY]

That should not happen if they are fitted into the channels tight. I had to try and removed on and I almost had to break it to get it out. So not sure what happened with yours. I wouldn't glue them unless it is just around the border of them. You really want to have that air gap between the door and the insulation

[@10forthebigguy753]

That looks like the insulfoam kit I bought at Home Depot. About $63 each two years ago. It turned out perfect for me.

[@kimmybartz3074]

@howtohomediy - great video. How would you insulate a garage door that doesn't have the channels to hold the insulation foam? Thanks

[@jeffpaulwilson]

My garage door openings are 24" tall, but this product is only 20" tall. Will it still work, or do I need a different product?

[@firstdown80]

I installed NASA Tech White Reflective Foam Core. Definitely drops the temps in summer by 9 degrees. Unless some sort of ventilation for circulation, heat stays in after you park the car.

[@davebean2886]

Yep, once hot, garage stays hot. Any ideas for ventilation?

[@firstdown80]

@@davebean2886 When I installed the insulation, the product business owner suggested a ventilation fan out. I suppose it’s one of those shutter exhaust fan. Open to let the heat out and close it.

[@CindyCindy3252]

I had a low profile attic roof fan installed. I also have insulation in my garage attic. When it's Alabama HOT and I park my truck in the garage, I will leave the door open a while. I keep the removable attic door open and when the thermostat kicks the fan on after I close the door.. it helps pull the heat from my truck and garage out. I also have a 3 bank digital thermometer in my house. I have one monitor in the garage attic and one in the garage. I can see the temperature drop as it pulls and circulates. If I want it to drop more I may raise the garage door open about a foot to really get the air circulating. 😎

[@ThanksForTheLaugh]

I was surprised how much cooler my garage is after I switched to an EV. No more heat soak.

[@vincentar850]

I used cello foam at Home depot. You will need to upgrade or adjust the spring.

[@rickzwolinski]

Why not the board with the reflective liner? I did pretty much same thing to my garage door.

[@GenTikki]

I wonder if it’s possible to at least try to hurricane protect a garage door. No flooding where I live 🤞🏼but lots of strong wind!

[@HowToHomeDIY]

That’s why I have all of the hurricane bars on my door.

[@clarencewiles963]

Thumbs up 👍 good job. Thanks.

[@dwayne7356]

What's the fire rating or flame spread rating? Unprotected ‎polystyrene is flammable. Not something I would want in a shop where sparks or welding happens.

[@johnpicard4909]

Pretty much everything used for garage door insulation is flammable.

[@PeaOwed-again]

doesn't the extra weight affect the motor lifting the door?

[@HowToHomeDIY]

I think I addressed this in the video. There absolutely is an effect in that you are adding weight and any weight changes the current scenario. Now is that weight enough to have enough of an effect on the motor? That depends on many things like the motor and the balancing of your torsion spring. With mine there wasn’t much of a noticeable difference. The material I used is quite light. But if you find your door has slowed going up or it comes down much faster then I would suggest having a garage door installed adjust the torsion spring to balance the door.

[@CJ-ty8sv]

7:50 use the straight edge as a guide for the blade rather than trying to free-hand following a drawn line.

[@HowToHomeDIY]

Unfaced polyiso board in warm climates?

[@woodrowwilliams1812]

Did you install the horizontal struts? I hadn’t seen a door with any struts other than one across the top

[@SgtJoeSmith]

I had to on mine after door got to be 20 years old. Been working like new again last 15 years. Had to turn spring a bit tighter. That was a bit scary

[@RJ-sr5dv]

The link to Amazon site says the panel is 54” X 20.25” at $155.00 -- assuming g what they mean to say that the package includes enough to do a single car garage it’s not too expensive The big box stores sell a vinal faced fiberglass insulation kit with precut to size pieces for about $110.00. I did this but the plastic retaining clips that come with don’t do a very good job

[@HowToHomeDIY]

I never wanted fiberglass insulation. It’s not the most efficient, will weigh the door down more, and I doing think it looks very good. But totally up to you.

[@WayneTDowdy3]

Thanks! ❤

[@rthomashouse6140]

Also, how do you ensure the air gap between the panels and the door will persist? The insulation isn't secured by anything other than friction, so I bet they move.

[@HowToHomeDIY]

They haven’t moved at all in the month or so they’ve been installed.

[@JahongirHaitov]

So what was that crucial mistake and the important tip? I missed it

[@johnpicard4909]

I think it is where he talks about making sure there is an air pocket. Pretty much everyone misses that.

[@JahongirHaitov]

@@johnpicard4909 Think it is not sustainable, in a moving structure, the foam board will be moving all over the place by itself. I would suggest gluing small "feet" to the board before installing so the gap is hard-enforced.

[@HowToHomeDIY]

@JahongirHaitov mine haven’t moved at all. In fact, I have to give them some force to get them to move towards the door. If you cut them to where they fit tight like they should, there will be no issue.

[@frankmckinnis]

What would you use for a roll up door?

[@HowToHomeDIY]

So as far as I know there is really only one choice for those. I’ve really only seen it done with an adhesion kit that uses something like 3M tape. If you put in roll up door insulation in an Amazon search you should see examples of what I’m talking about. I think Blue Tex is one you will see.

Please do a video on removing light bowing on a garage door

[@johnpicard4909]

You replace the garage door.

[@Edward-xj4mp]

With all the added weight of insulation and struts on your door, you definitely need an operator reinforcement bracket.

[@dasfahrer8187]

Doing this is a waste of money if your door has a lot of light showing around the edges and/or underneath. Most garage doors installed in tract housing aren't installed properly as the builders don't really care about the garage getting hot/cold (which is also why the attic space above the garage often doesn't have insulation either), depending on the area of the country. Fix the gap issues first, then do this.

[@wayne9518]

Not for my door. Summer sun on the door, you can feel the heat radiating off the uninsulated panels three feet away. Anything that slows that is a big step. I have most of the garage attic insulated. When it gets cooler this fall, move some stuff and pull up the floor in spots to fit in some fiberglass batts.

[@RogerArnold-ji5nu]

Thank you mister helper

[@virgilsmith5792]

It's a special buy at Home Depot right now and you still get the military discount

[@paulsccna2964]

A real problem with a garage door is the edges. Often when the wind blows the door is pushed back, just enough to for small air leaks, to allow cold air into the garage. Thus, all that insulation is a waste, as the door leaks air around the edges.

[@GenTikki]

My problem is this but extreme heat instead of cold and hurricane force winds fairly often

[@scottjones9603]

Someone may already have mentioned this but NO need to draw a line on the foam, just lay the T Square or 90 on the piece that’s marked top and bottom and use that metal to cut against. Saves a step and gives a perfect line unlike eyeing it

[@dbenedict357]

Couldn’t you just add some thinner foam around the edges to ensure the air pocket exists and stays?

[@rthomashouse6140]

Why did your infrared thermometer read over 100 degrees if your garage door faces north and would be in the shade?

[@HowToHomeDIY]

Well it’s very hot here and while it’s in the shade we have vehicles on the other side that reflect the sun. I don’t know exactly why but that difference I showed is nothing compared to someone whose garage door is in direct sunlight. Those temperatures can be 130-140+

[@harvey66616]

I see at least a couple of advantages to using the kit. But it's hardly the best option insulation-wise. Polystyrene's not bad, but you can get almost R-6 from 1" of polyisocyanurate (usually just called "polyiso" or even just "iso"), i.e. more insulation from less thickness. And at such low R values, the difference between e.g. R-5 of 1-1/4" polystyrene vs R-7 of 1-1/4" polyiso is significant (almost 50% extra insulation value). Alternatively, you'll add less weight using just 1" of polyiso vs 1-1/4" of polystyrene (roughly 20% less weight, since the two materials are around the same density).

[@HowToHomeDIY]

I disagree. iso board does not offer a higher R value at that thickness. Also, I don’t know if you’ve ever handled iso, but it’s much heavier than polystyrene. I spent well over a decade working with iso board and one of the main reason we used it is because it is dense and rigid which in turn makes it weigh more.

What is the thumb nail comment "This will lose air" referring to? Also, I have to say, I would have thought that those panels would have reduced the temperature by a little more than 10 degrees.

He said it faces north so it should be mostly shaded. 10 degrees would be a lot then.

When I was a kid, a one-piece garage door extension spring failed from fatigue while I was home. Shrapnel rocketed into the ceiling of the garage and hit the inside of the roof. Torsion springs are far safer in fatigue failure. Don't mess around with large amounts of stored mechanical potential energy.

Foam is sufficiently useless unless it’s air tight. Foam friendly caulk or something is crucial. A temp gun does not measure the air escaping, the foam never fits perfectly, and foam degrades.

[@danoberste8146]

Please determine the flammability and toxic smoke generating properties of any material you install in a garage, or any other areas of your house. There are forms of styrene that do have fire resistive properties, so MAY be safe, but I know there are others that firefighters refer to as solid gasoline because of how fast they ignite and burn, There may be kits for this, that use approved materials, but I'll bet the cheapest you can find at a big box hardware store WON'T be that kind. Saving a few dollars on your energy bill isn't worth asphyxiating and/or burning your family to death.
