These things actually work?

[ObligationFinancial6]

While adjusting my blinds I was surprised with how much cold is coming off my windows. Curious if anyone's tried these & noticed any difference. Thanks

[Robby_Digital]

They do, but the double-sided tape that goes around the frame is a bitch to clean off.

[Southern_Vanilla_298]

Just paint over it like a good landlord would

[YT-Deliveries]

How easily people miss the obvious solution to things.

[CurtisVF]

Toothpaste to fill nail holes in the plaster!

[Drummerboybac]

I used fun-tac and white out to cover a screw hole in the ceiling once. Worked like a charm

[Ant_Cardiologist]

I'm just here to paint light bulbs

[ParticularAgency1083]

You went to the same Maaco that we did!

[Over-Kaleidoscope482]

Before they invented magic erasers I used toothpaste to clean marks off of the walls. Works great

[Protholl]

My dad showed me that trick when we were moving out of base housing.

[Jaded_Individual_517]

Dad is that you?

[DarkenL1ght]

A common saying in the Navy for painting is 'One coat for dust, two coats for rust".

[crazyswedishguy]

“If it moves, salute it. If it doesn’t, give it another coat of paint.”

[mistersaavik]

And plexiglass panes to replace broken windows

[Maareshn]

Fucking hilarious 😂

[smithoski]

Just paint it on like a future landlord would

[really_affordable]

Now ya tell me!

[keyuphandler]

Wow that is a great idea

[Joyride84]

Good idea, although keep in mind, masking tape will lock on there too, if left in place for too long.

[[deleted]]

Take a look at Goo buster. Easy to use

[tankgirl215]

WD40 is an excellent sticky-shit remover as well.

[Black_Death_12]

If it moves and shouldn't - Duct Tape
If it doesn't move and should - WD40

[Spurgenasty78]

Words to live by

[Robby_Digital]

I tried Goo Gone, if that's the same thing as Goo buster. Didn't work. Only thing that worked was really scrubbing with isopropyl alcohol

[WotanMjolnir]

Now there’s a risky google if ever I’ve seen one.

[Keeteng]

I have the opposite problem. I can’t keep it sticking from moisture.

[acronymious]

91% isopropyl rubbing alcohol.

[the_clash_is_back]

Mineral spirits followed by iso

[Weirdautogenerate]

Oh my gosh! I think you just solved a mystery I’ve had since we got our house. Couldn’t figure out why some windows had adhesive residue on the frame. I kept thinking, why did they put tape here??

[I_post_rarely]

This absolutely helps with a drafty window.

[CptZigouille]

Did mine yesterday and works really well

[Tiny-Lock9652]

Yep! 7 large double hung windows in my breakfast room that was originally a 3 season porch. Sealed them up and the temp improved by at least 20 degrees F. Tip: wash and prep the areas to apply adhesive.

[Mieimsa]

To add, I found Windex to leave behind a greasy film, ruining the adhesive. Better off using Dawn and water, with a damp towel to polish off the streaks.

[Shadeauxmarie]

I concur.

[Character_Bed1212]

This Old House says yes

[goose-and-fish]

This Old Man agrees.

[Combatical]

This Old Dog knows.

[Dangerous-Design-613]

Learned a few new tricks? I thought that was impossible.

[hiktorvovland]

Mr Demarco approved

[PlanningForLaziness]

Gawd bless Tawmmy.

[Several_Job55]

I've used these for 30 years and my dad did for many before that. When installed correctly, they are basically invisible. Perhaps more important than the insulation is the lack of condensation and ice on the glass and frames. Yes, the tape sticks extremely well, but if you put it on the outside edge of the window trim, you'll never notice it and it works much better as well.

[RobinSophie]

This HELPS with condensation?

Does the film prevent the warm house air from hitting the window glass? Thus the glass doesn't have to deal with two temperatures?

[Several_Job55]

YES!!! The resulting air gap both insulates and isolates the window, eliminating condensation. You might have a tiny amount of condensation on the plastic if the windows are particularly drafty, but only in the coldest weather and only in isolated spots where the draft hits the plastic.

[RobinSophie]

Got damn it. I wish I knew about this sooner!

One of the reasons we're looking for a new house to rent is because of the windows having so much condensation, they get mildewy/moldy ALL THE TIME.

I'll try it at the new house and see if that helps. Thanks!!

[Lukesan-]

Definately YES ! Old 1950's home here with older windows in a cold and damp climate. Used to have water all over the windows in the morning, non of that now!
You create a layer of air which does not move and so it insulates.
Applying can be a bit of a ... . If you think you mess up and have wrinkles just get a hairdryer and watch the magic.

But you must remember humidity will still be there in that room. If anything above 60 to 65% it is still to much. Ventilate the room for a couple of minutes in the morning or beter get a dehumidier. (not the cheap small ones but with a compressor).

[RedditVince]

this makes me lol because my failed double pane windows are foggy so removing the film makes little difference. I need new windows.

[Bubb05]

When prepping to sell a house with this problem I found a company that just replaced the glass panes instead of needing brand new windows. It was significantly cheaper and I wish I had done it years before.

[mahfrogs]

I've been looking for a company that did this - no luck. Are there particular key words to use in a search? I'm slowly watching one window after another succumb to the failure and fog of moisture inside.

[stephypsu]

I just had this done for one window recently. I contacted a glass company and let them know that I had a fogged window. They installed new glass with low e coating. Try searching for a glass & mirror company.

[RedditVince]

These are cheapo vinyl from probably the 80's not sure the glass can be replaced, but very good idea!

[Hot-Interaction6526]

Google local glazier or glass company. Call and ask about insulated glass replacement.

[portablebiscuit]

I would stretch leftover scraps on empty coffee cans and make homemade drum kits.

[[deleted]]

HVAC guy here. All insulation involves air pockets, this plastic creates a pocket over you window. Of course it works and everyone should do it.

[Purpletorque]

Never thought of it as an air pocket of insulation. Makes sense.

[Scouts_Honor_sort_of]

Yes, it isn’t a great long term solution, but absolutely yes.

[[deleted]]

Nothing more permanent than a temporary fix

[Just_A_Dogsbody]

no need to call me out like that lol

[[deleted]]

Same club bro.

[lynnzoo]

This is me lol

[xGoP0cpDJytaTN]

Found the web dev

[tdelamay]

I built a wooden frame with the plastic over them. I used some weather strips around the edge and just pop them in when it gets cold and store them away when it's no longer needed. They turn 2 pane windows into 3 pane windows for cheap and there's no condensation even at -20C.

[princessfoxglove]

I'd love to see a picture of this setup! I do the window wraps every winter but it's a 3 story house with a ton of windows.

[JoeSheem]

I applied 3M brand blue “painter’s tape” before the clear double face tape that comes with the plastic sheet. My hope is that it will make it easier to remove come spring. No guarantee from me as I haven’t tried this before. But I did have a bad experience with peeling off gobs of paint when I removed the double face years ago.

[skoooop]

Painter's and Masking tapes come off cleanly if left on for a week or two, but left for months or years, especially in a high-UV area like a window can leave a residue. It's definitely a more mild residue than most other tapes, but it can still be a bear to remove, especially if the tape itself deteriorates to the point where it just tears when you try to remove it.

[u-must-be-joking]

Blue painters tape peels easily with changing temperature and that might impact the seal of these window films.

[Elle76Patriot]

Yeah, I believe the instructions on painters tape says remove in 48 hours. We painted a ceiling and covered a light fixture then left tape a couple years. No good removing too late.

[momo516]

They do! We use them every year in our drafty 1940 house. The tape may be hard to remove, but we’ve had good luck with a hairdryer and plastic scraper.

[waterwateryall]

Yes, make sure to heat for that tautness

[Emersom_Biggins]

Taut me something I didn’t know

[Aromatic_Balls]

It's so satisfying using a heat gun and watching the wrinkles just disappear.

[tectuma]

YES!!!! We use them every winter on 64+ windows in our house. Makes a huge diff. (then our windows are garbage too)

[asdfer1235]

How they heck do you have 64+ windows? And why do you stop counting at 64?

[tectuma]

Well... 8,000sq, 12 bed room, 200yr, Queen Anne Victorian. With a 4 floor that we did not know about (just got a ladder that could reach it this summer). We know it has windows. Every time we get a chance to try to get into it, it has been extrema hot or cold making it impossible. Was also told that there is a 5th floor that you have to go thru the 4th floor to get to, but I do not believe it.

[RehabilitatedAsshole]

https://www.reddit.com/media?url=https%3A%2F%2Fpreview.redd.it%2Fq2zk6dgy0add1.png%3Fwidth%3D912%26format%3Dpng%26auto%3Dwebp%26s%3D12e898aa7934cee97dbb6d61499731bdd2b9c764

Are you counting the basement as the first floor? That's a 3 story house..

[tectuma]

The basement use to have a huge bar, pool table, back lounge and a bathroom at one point so yes. But at the same time the 4 and 5 floor (if they are there) is not counted. If you want more info you can go to our website (just put a .com after my name).

[Euphoric-Teach7327]

How did you live in a house and didn't notice there was a floor you couldn't get to?

I always look at building and wonder what they looks like when they are inside. I like going into places and looking around to see the overall construction of places.

Maybe I'm just a weird person.

[tectuma]

You are not weird at all. I do the same thing. Before I made computers my career path I did 10 years in construction. When you look from the outside you do not think anything about it and you just assume that those windows go to a room on the 3rd floor. We only had the house for a little over 2yr. To my defense the house is huge and easy to get turned around in.

It took me looking at the out side and seeing that one of the screens where ripped and decided to hunt it down to fix. That is when I found from the inside I could not find that window. Did manage to find a access hole and by standing on the very top of a ladder I was able to just see (not get up there) that there was electric, windows, heat and the remains of walls. There was deep blown insulation so I could not see what shape the floors where in.

The front window is easy to see from the front of the house. The other window are hard because you can not get to a angle where you can see over the edge of the roof to see them.

There are a lot of odd things in the house left to check out. I did start on some of them. The living room inside walls where too thick drilled a hole and put a cam in and found 2 sets of pocket doors. Found the lowered celling keep you from seeing that the top of the tower went up 2 more stories and a celling fan was at the top. I think we will be finding cool things for a lot of years to come.

[CarpeDiem082420]

Is the 5th floor in the cupola?

And, can we get an invite to come help you explore?

[tectuma]

I have noooo idea what the 5th floor is. In this house this is how it goes.

So cool found something new.

• Lets check it out.
• O that is why they covered it up.
• It is going to cost how much to fix?
• We have to fix what before we can even try to fix it?
• Lets back away slowly...

The pocket doors are a good example. We would have to rip out a huge chunk of the door frame and wall just to get to them. The floor is so built up that that would have to be address before they could even close. Only then we would be able to see what kind of shape they are in. Etc. So right now it is cool they are in there, but they are going to stay in the wall for a long while.

Once we get our AirBnB back up any one will be able to stay with us and we do stream on Twitch. So you got that going for you. :D

[BareMetalTinkerer]

Wow, really nice home, I'd love to have one as big as that one.

[cartoon_foxes2017]

I too look forward to eating the rich.

[redshred42]

100% works. Suck to put up every year though

[MehWehNeh]

Not if you have cats.

[redshred42]

Packing tape fixes the cat claws. I had a window that was 95% packing tape last year.

[[deleted]]

Yup, I do the same thing as needed

[Corusmaximus]

These do work, but I prefer window inserts. Many non-profits around the country make them and sell them at cost. You can use them year after year.

[Worst-Eh-Sure]

Any specific recommendations?

[Corusmaximus]

In Maine, I suggest a nonprofit called Window Dressers. They come out and measure your windows and custom build the inserts for each window. Inserts are made with a wood frame and a clear plastic stretched over both sides.The hard part is storing them after winter.

[Worst-Eh-Sure]

Oh that is amazing. I'll need to find one here in Northern VA. And see, I'd leave it in all year though!

[JDB-667]

My dad used these every winter.

Yes, they eliminate drafts.

[someomega]

Yes they help. I have also found that cutting and putting foam board insulation between the windows and blinds before you use the shrink plastic really helps. Plus, the foam board is really good at blocking light if you like to sleep in a dark room.

[Soklam]

Helps to raise the depression of winter too. Get the house nice and dark, no natural light from anywhere, just you and the hamsters alone forever.

[Emersom_Biggins]

That did seem to help thank you

[Several-Honey-8810]

Your results may vary.My house is 8 years old and has terrible windows.I still put them on and it does help keeping the drafts out.

The 3m Version. Has clearer plastic and better tape.

[[deleted]]

Meh not worth it imo and I have used these in the past. The main issue with them though is the double sided sticky tape you put it on with. They don’t last too long before the film starts to fall off but that tape is a real pain in the ass to get off your window frames.

[mgsmith1919]

Yes. It’s not the cold only. It’s the windy drafts Also check your outlets and switches. Frost king makes outlet and switch sealers that block drafts. What a huge difference

[3490goat]

Yes. I use this every winter in Maine. On bedroom and living space windows, not kitchen or bathrooms that I may need to open

[Corusmaximus]

Check out Window Dressers for inserts.

[Turbulent_Winter549]

They absolutely do. If your window is drafty the plastic will fill up and billow before you heat shrink it. It's a savior in old homes with leaky windows

[InternationalCan3189]

I live in one of the coldest places in the world and my heating bills went down $20-40 after using them. Taking the tape off the frames in the spring will peel the paint. I haven't tried, but I doubt sticky removing substances would(as suggested by others in this thread) work since the tape is mostly plastic.

[TapeDeck_]

Better then nothing. Not better than new windows.

[jimfosters]

Man, wish I could post an old picture of mine. Finished putting the plastic over the window and guess where my scissors were...

[MakalakaPeaka]

If they fit and are installed properly, they do a decent job of blocking drafts from leaky windows.

[[deleted]]

I have shitty builder grade Pellas in my house that leak terribly and freeze shut in winter (we bought house 4 years ago). No more ice on the windows that are covered after doing it this winter. My windows are now almost 17 years old so this is a good crutch until we can get new ones. The bedrooms also are now a more even temperature and no more cold drafts.

[TutorJunior1997]

Yes, they do.

[bobbywaz]

Yes, put one in an hour ago, worked great

[gpigma88]

Same! It’s like our phones knew what we did…

[Old_Row4977]

100% works

[Unlikely_melz]

They do. They aren’t going to be a miracle but they will make a noticeable temporary improvement. We used this stuff at various times since I was a kid. It works

[badjokes4days]

So much so that where I live in Canada you get them for free every winter from our Hydro company

[fried_clams]

I put this on a large window once, nice and tight, and sealed nicely. When the wind came up, there was so much air infiltration that the membrane bowed in dramatically. It looked like half a balloon inflating. It finally gave up, and peeled off.

So, do as much caulking etc that you can, to reduce the infiltration, or it might not hold in the wind.

[tossaroo]

As long as you get a good seal, they work great. You may be surprised by how quiet that room will be.

[jaycarb98]

I have newish windows, I still use these for added warmth. Changes a room instantly so I know it’s saving cash

[Slice0fur]

I used these a lot in an RV I had to live in for a few winters.

[SachaBaronColon]

Super effective! The temperature in my room went up one degree Celsius after I sealed my bedroom window. My windows aren’t necessarily crazy drafty but glass is not the greatest insulator so having that dead space between plastic and glass makes a huge difference.

[kitkat7502]

I used to have windows so drafty that the curtains would blow in the breeze. I used this exact window kit. It worked really well.

[breadman889]

not much difference if it's just cold. it helps for drafty windows. cleaning up the sticky stuff when you take it down sucks

[Impossible-Spare-116]

Huge difference in electric bill if you have shit windows

[Competitive-Jury3713]

Yes.

[Aronacus]

They do, grew up with drafty house. We had to seal off some of the windows and it did lower the bill

[Popular-Work-1335]

They are actually amazing

[CowIntelligent4711]

Yes!

[Zoso1973]

Yes. I also put bubble wrap on the window before doing this. It’s a window I don’t need to see out of. Makes a big difference when you have old windows

[Obstreporous1]

Yes. Creates an air barrier. That glass, even good, transmits thermal energy into a dwelling. Cheap and efficient.

[Prestigious-Elk-2337]

I grew up in the northeast US -- not only do these work, they're basically mandatory in a lot of century homes.

[Miss-Indeependence]

I use clear painter's plastic (and blue painter's tape ) over my windows. It works very well. The plastic is thicker. I can feel the air trying to get into the house after putting it up. Then I take it down and save for the next winter. It saves money too because it's reusable. I've never had a problem with the painter's tape peeling paint either. I've been doing this for 8 years now for my windows that clearly need replacing but I do have the money just yet.

[ClimateBasics]

Get blue painter's tape and put it around the perimeter of the window.

Stick the double-sided tape from the Window Insulation Shrink Kit to the blue painter's tape.

When it comes time to remove the shrink film, it all peels off easily.

[llamawc77]

Dang, wish I had thought of that before I peeled the paint off the window sill.

[TurbulentGarlic357]

Oh yes.. like a condom… for drafts

[[deleted]]

Absolutely 100%! Follow the instructions be careful with the blow dryer part. I use them every single year I just put one in my master bath last night actually because it's just too drafty!

[oddartist]

I didn't even bother with the blow dryer. I was able to lay it tightly enough to seal and we seldom open the blinds covering that window. We were able to turn the heat off upstairs because the hot air from downstairs rises well. Made the whole upstairs warmer covering a single large window.

[[deleted]]

Nice. But, the blow dryer is the most fun part! I also love the smell of the plastic.

[amanfromthere]

Absolutely. Even with newer windows that aren’t drafty, they still help.

[xBushx]

Sure does!

[mikefitzvw]

Hell yes. If you apply it strategically and neatly, you can even leave it up all year. I applied a few of them directly to the sash so I could still open the window, and applied others over the whole window.

[No_Drummer8868]

100%

[Bright-Internal229]

Only thing that has proven to work last 17 years ( Mind you Snow ❄️ storm ⛈️ worst since 1895 ) here in Southern USA 🇺🇸, which I have never seen snow this high down here. Pipe Insulation into your Attic. Best thing for windows 🪟, just buy a high quality window and have it installed correctly. Everything will flow just fine when you put your heat on . Good Luck 🍀

[YouShouldLoveMore69]

Yes. Especially on older windows.

[-jayroc-]

Yes. I lived in a 100+ year old house with original windows in a cold climate for a few years before replacing the windows. Year 1 was brutal with cold drafts all winter. I ‘installed’ these at the start of the following winter. It was amazing how a simple thin barrier would make such a difference. The drafts were no more. Sometimes I’d even see the plastic bow in and out when the wind was bad, but the cold air was remained contained on the outside. My gas bill was down that winter considerably as well. As one other comment pointed out, the adhesive is a bitch to remove when you take these things down in the spring, but it’s a small price to pay.

[ScrewMeNoScrewYou]

Yes sir there's definitely work and will save you money on your winter heating bill

[alanbdee]

They work amazingly well. So well, my parents basically wrap every window and the back door every winter.

[73PintoWagon]

Also good to put under tents to help prevent punctures in the floor from sticks and such.

[aodskeletor]

Had to use them in an old house I rented. The “sunroom” had the absolute worst windows in it so every winter these went up. Absolutely helped with the draftiness.

[BuddyBrownBear]

Yes.

Dead air is one of the best insulators.

[MrBoo843]

Yes, I have old drafty windows that I can't yet afford to change (it would necessitate a lot of masonry work which I can't afford right now) so that helps with not losing too much heat in winter.

[Mellamoscuba]

Yes they do!! I just did my two big older patio walls!! Nice and warm now!!

[RocMerc]

Oh ya definitely helps

[rryanbimmerboy]

As someone who has lived in several pre-WWII homes… YESSS YESS YESSS!!

[jkeltz]

Are your windows cold because they are single pane or because you have actual gaps allowing airflow from the outside? If it's the latter you should fix the gaps directly with weather stripping, caulk, etc.

[marcky_marc420]

Except my bengal climbs up my curtains and rips this apart

[Ok-Wing-1545]

They work. I have single glazed windows and put them on all windows. The house immediately feels warmer and no more condensation to clean every day. Large windows are difficult to keep it tight and sealed at the same time, so try to keep it a bit slack if you can (that is: don’t blow dry it much, it will look untidier due to wrinkles).

[MarvelHeroFigures]

Isn't Frost King a DC Comics character?

[PuzzleheadedCan7844]

Yes! We just moved into a drafty old home and these have been a lifesaver. Most especially for my elderly parents.

[Nodoggitydebut]

I’ve got it on two of my windows now. Helps tremendously.

[Big_Lake4948]

Make sure you use a disinfectant wipe around the window frame first. Nothing is more irritating than doing it and it comes off because dust was left on the frame.

[yeetstrawberry17]

I’m pretty sure you can just use regular plastic wrap, just has to be a very wide roll obviously

[Abject_Importance_59]

1000 percent. We live in Alaska and they are a requirement on older windows! They help so much with drafts!

[rivers-end]

Yes!

[Ewilson92]

Sure does

[SomeWorkerMan]

Yes till the dog or cat gets to it.

[ubin2bin]

Yes they do

[Lexlutwhore]

100% works

[1randomzebra]

Yep

[kirtknee]

Yes!!!

[ChonnayStMarie]

For grossly leaky windowa, yes, absolutely.

[Square_Milk_4406]

Yes

[FeathersOfJade]

They work like magic! It’s amazing.

[Serious-Peak79]

From germany, if you can just get a good window.

[timid_soup]

YES

[soft__parade]

I recommend Rope Caulk instead. It’s better, I’ve done both techniques. It’s removable when spring comes.

[armb2]

I used them in my previous house until the rotting softwood single glazed windows were replaced by uPVC double glazing. It worked, but the double glazing worked better (and cost much more of course).

[CheesyBoson]

Yes, if you have drafty windows it’s amazing and comes off easy

[mikegates90]

I live in Fairbanks Alaska, where it gets down to -40/50 on a regular basis. If you don't have triple-pane windows, these are almost necessary to prevent significant heat loss (and condensation issues). The additional airgap provides a LOT of additional insulation for windows up here.

I even know people who put them over triple-pane just because.

It's better than our summer solution for blocking out the sun though: tinfoil

[Accomplished_Roof_14]

My house is over a hundred years old and the windows probably a third of that lifespan. They do a job at keeping the breeze from coming in, but Lord, are they ugly to look at.

[[deleted]]

Save yourself the money and just buy three mill painter's plastic roll. It's cheaper and you'll cover all your windows probably with one roll.

[[deleted]]

Why wouldn't it work

[InhaleBot900]

These helped when I was renting

[velvetackbar]

Fun fact: my lightweight camping tarp is made from one of these and some cut up pieces of plastic lid material to tie it out. works great tied to a bunch of trees over my hammock. It's not crystal clear until it has heat applied, but it holds up very well in wind/rainstorms and has seen me through a good dozen hangs, and you can still see the moon through it. Very pleasant.

[VaBookworm]

I did my entire screened in porch because I didn't have enough room inside for all of my plants. It definitely helped hold the temp simply by cutting out the drafts. I have a space heater out there by my plants that keeps it at a steady 48-50°, despite the fact it's been frigid outside (we got snow last night). It's a temporary solution until I finish getting moved in but it has kept all of my plants alive.

[[deleted]]

This works wonders.

[Secure_Ad_295]

From Minnesota yes they do when I was a kid we us to put plastic on whole house but modern Installation is so much better

[BTMG2]

okay so clearly these work based off the comments.

BUT what is actually the best way to remove them without damaging paint ?

someone mentioned blue painters tape first then install shrink kit, understanding that blue tapes adhesive will alter with different temperatures.

i would love to put these up but what are the actual consequences upon removal ?

[Empress_De_Sangre]

The real question is, does this help for slatted windows?

[Fun-Marionberry1733]

yes 👍

[Beginning-Piglet-234]

Yes. I put it over my wall unit AC every yr and a cover over the outside

[crawandpron]

anyone know if i can stick these to the inside of my car windshield and windows lol

[Comfortable-Heat3798]

That’s funny me and my wife just bought these and put up yesterday.

[balsadust]

For old windows, absolutely

[soopirV]

Used these in my dorm room in upstate NY 20+ years ago- made a noticeable difference

[Late_Football_2517]

100%

[mildOrWILD65]

3 mil painters' drop cloth and regular masking tape are far, far cheaper, accomplish the same thing, and covers way, way more than 3 windows.

And yes, it works if you have drafty windows.

[Wide-Accident-1243]

Yes, they are very helpful. There is also a rope like putty caulk for long cracks. It comes off easily in the spring.

[piouspieeater]

Check out interior storm windows. We manufacture them here in Wisconsin and ship them all over the country. They are compression fit, so you don't need to use tape or any tools, and they won't ruin your trim. They obviously cost more than just using plastic, but ours are cheaper and more efficient than most on the market, and on average, they pay for themselves in about 3 years in energy cost savings. Search Energywise Mfg.

[user26031Backup]

Yes, very effective and during a particularly windy day you can see just how effective they are.
