Spray foam insulation is a liquid that expands to fill gaps and cracks, creating a seamless, airtight barrier that can reduce energy consumption and improve the insulation of metal buildings. It forms an integral part of the insulation process, ensuring optimal insulation density, adhesion, and thickness. To make a patio door more energy-efficient, one can use a professional spray-foam gun to air-seal around the door.
To add insulation to metal doors, you can install a deadbolt, weatherstripping, draft guard, and an insulating layer on the inside of the door. Air sealing the rough opening around doors and windows before installing trim to minimize air leakage is essential. You can fill the cavity with caulk, canned spray foam, or foam backer rod.
It is important to avoid high-expansion foam, as it may create a mess for the next person working on the frame. Foam insulation boards (DOW BOARD) can be used to glue or screw with washers to the door, regardless of its steel content.
Instrumental instructions advise against using expanding foam because it may warp the frame and door not seal properly. However, wood doors can be used and installed in most hollow metal frame applications, including FE-Series and DE-Series Double Egress frames. Both honeycomb insulation and polystyrene insulation can be effective at insulating hollow metal doors, depending on the specific application. Closed-cell spray foam insulation can increase structural integrity, regulate temperatures, reduce noise, and protect against condensation in your metal building.

Will spray foam stick to stainless steel?
Spray foam represents a versatile solution for a range of custom, specialty applications, including the insulation of stainless steel structures such as wine storage tanks. The aliphatic coating, which is applied with heat and primer, sets rapidly and is safe for use with wine and spirit tanks. Furthermore, the ChemLINE product exhibits resistance to acids, rendering it an optimal selection for such applications.
What is the downside of using expanding foam?
Improper application of spray foam can pose health concerns due to its harmful chemicals, particularly airborne ones that can cause respiratory problems. Proper ventilation is crucial during and after installation, and understanding the chemicals in spray foam insulation can help homeowners make informed decisions. Spray foam insulation is more expensive than traditional materials like fiberglass or cellulose, but it may provide significant energy savings over time.
Prospective buyers should weigh the pros and cons of spray foam insulation to determine if the initial investment is worth the potential savings. Additionally, proper installation of spray foam insulation requires professional expertise, as incorrect application can lead to uneven insulation, gaps, or moisture trapping, potentially causing mold growth.
What material will spray foam not stick to?
To ensure foam adhesion, test the moisture level before spraying on a wet or damp surface. If the surface is wet or damp, moisture can cause off-ratio foam with poor physical properties and adhesion. If foam is sprayed thicker than recommended, excessive heat can cause odors, cracks, shrinkage, or charring. Never spray more than a 2″ thickness at a time and apply in layers, allowing the foam to cure for at least 15 minutes between layers. The ideal temperature for both foam and surface is between 65° F and 90° F. Colder surfaces may result in reduced yield and condensation, similar to spraying foam onto a wet surface.
Where not to use expanding foam?
Expansive foam should not be used near lightboxes, ceiling lights, or heating appliances as it can catch fire due to its flammable nature. It may also cause damage to the light itself if it cures around wiring. Some foams may claim to be usable in close contact with ceiling lights, but it is recommended to consult a professional for guidance.
Pre-existing conditions should not be used with expanding foam without a mask, as it contains isocyanates, a chemical that can cause serious breathing and skin-related issues. To avoid these risks, use breathable masks and protective eyewear. If you are at risk of serious side effects, find an alternative method of filling cavities.
When purchasing foam, choose the correct type, such as open and closed cell or high expansion and low expansion, as they behave differently. Open-cell foam is more effective and expands quicker than closed-cell foam, making it an alternative to installing new insulation.
How to insulate a metal exterior door?
Polyurethane Foam Insulation is a popular choice for metal doors due to its thermal insulation and sound dampening properties. It is injected into the hollow core of the door, filling the cavity and providing an airtight seal. Mineral Wool Insulation, made of rock or slag wool, is effective at absorbing sound and improving fire resistance. It is typically placed inside the hollow core of the door and is lightweight and easy to install. Fiberglass Insulation, made of glass fibers, is also popular for insulating hollow metal doors due to its lightweight nature, heat transfer reduction, and potential energy cost reduction.
What are the negatives of spray foam?
Spray foam insulation, typically made of polyurethane, is known for being one of the most airtight types of insulation. However, it can lead to mold problems, foul odors, improper chemical mixing, termite damage, and being too airtight. It should not be considered an air barrier when pursuing energy-efficient homes like Passive House or Net Zero Energy Ready buildings. Spray foam can seal small gaps and tight areas of home framing, but it is not the safest insulative material.
The negatives to using spray foam insulation for homes might outweigh the positives, so it is best to consider alternative materials. Home builders should consider the pros and cons of each insulation type to ensure the safety and energy efficiency of their homes.
Does spray foam corrode metal?
Spray foam is generally safe to use to prevent rusting metal, but some lower-quality products can cause acidic reactions. It’s crucial to know the insulation contractor’s product to avoid damaging the metal building. Closed cell foam spraying can cause condensation, as it comes out at high temperatures. If the cold outside temperature is too low, condensation can form on the metal. If another layer is applied, this condensation can trap on the metal, causing potential issues. Therefore, it’s essential to choose a product that won’t cause damage to the metal building.
Can you spray foam on steel?
This article examines the challenges and considerations associated with the application of spray foam insulation in cold weather, with a particular focus on its use in steel siding and roofing. It offers insights into the optimal time for insulation, with spring being the preferred season due to the relatively mild temperatures. Nevertheless, deferring the undertaking until the arrival of spring may not be a viable or preferable option in all cases.
Are all steel exterior doors insulated?
Steel doors have several disadvantages, including limited aesthetic options, durability, and energy efficiency. They are popular for garages and side entries due to their flat, painted colors and lack of wood-like appearance. Steel doors can dent easily and rust over time, which can shorten their lifespan compared to fiberglass doors. Additionally, steel doors are not highly energy efficient, as metal is a conductor, making them drafty. Despite the availability of insulated steel doors, they still don’t offer the same level of energy efficiency as fiberglass doors, as steel absorbs heat or cold.
To find the best exterior door material for your home, visit Zeeland Lumber and Supply, which offers exterior doors in fiberglass, wood, and steel from top brands. Visit their local showrooms to find the perfect fit for your home.
How to make a steel door warmer?
To properly insulate a hollow metal door, follow these steps:
- Insulate the door frame perimeter. When the metal door is in the closed position, it seats into the door frame. A neoprene, silicone, or polyurethane bulb seal can be attached to the inside of the door frame perimeter where it meets the door. When installed, the door will close and hit the bulb seal on the door frame, compressing it for a firm seal. This seal will close any gaps between the door and the frame, properly insulating the metal door.
There are two types of door frame perimeter seals: adhesive perimeter seal and All American brand adhesive perimeter seal. Adhesive perimeter seal is fire-rated and fire-rated, but if not properly installed, it can peel off the door frame over time or be ripped off or snagged. To ensure proper insulation, it is essential to install the door threshold and insulate the bottom of the door with door sweep.
Where should you not use spray foam?
Spray foam insulation should not be applied directly to unvented crawl spaces or attics without proper moisture control measures in place. Without such measures, it can trap moisture, leading to mold growth, rot, or structural damage. It is also not recommended to apply spray foam insulation to HVAC equipment or combustion appliances, as the chemicals in the insulation can be flammable and pose a fire hazard if exposed to high temperatures.
Exterior applications of spray foam insulation require proper protection against sunlight, moisture, and physical damage. UV exposure can cause degradation of the insulation, reducing performance and appearance. Additionally, if the insulation is not adequately protected from moisture, it can absorb water, compromising its effectiveness. Proper exterior cladding or coatings are essential to shield spray foam insulation in these applications.

In this video I’ll share with you how you should (& shouldn’t) be using DIY Spray Foam in your remodeling and home repair …
Thank you Aaron! I’m a single mom and learning to fix my own issues. So far I’m doing pretty darn good – and enjoying my journey toward taking care of my family myself! I’m definitely teaching my daughters to take care of themselves too. For example, I service my own air conditioner every year and treat it monthly…and just fixed my neighbor’s air conditioner when it quit on a scorching SC summer day. I taught both of my girls when they were in middle school how to fix running toilets. articles like yours are so helpful, so I want to thank you for your help and guidance. (I do know, however, when something is over my head and when to call in a professional.) This being said I want to leave a note to Dads: Please teach your daughters everything you know so that they can take care of themselves when they reach adulthood!! They will be better and stronger women because of it! And they will always remember that Dad loved them enough to teach them. As for the LocTite, I just purchased some to hopefully deal with a carpenter bee problem. They come every year and set up under the railing on my porch. I’ve tried everything the experts say: insecticides, borer bee traps, citrus soap… but nothing works. They still show up every year and leave a huge mess on the porch. So, today I’m getting serious – and am going to try spraying Loctite foam under the rails and hopefully take care of this issue once and for all. I’ll let you know if it works! If not I may be tuning back in for help with this.
What the difference between the normal foam and the foam for larger 3″ gaps? I know that the latter expands more, but is there a difference chemically and structurally? Can I use the 3″ foam for smaller gaps as well? Or would the increased expansion actually force the small crack wider? Thanks for any info.
I learned a “don’t” when I bought a Condo in 1995. Although the Condo was only 5 years old, It had low grade Hotpoint appliances. The dishwasher was noisy everytime I used it. I sprayed a little foam insulation in the door, thinking the insulation will absorb sound and quiet things down. After spraying the foam in the door, I didn’t realize heat from the dishwasher would continue to cause expansion of the foam . After two uses, the foam continued to expand and the front door panel started to bulge. As funny as that was, the timer eventually got clogged with the expanding foam and the dishwasher became useless. I was going to replace the appliances anyway but didn’t realize it would be this soon. I learned my lesson and now pay more attention to the “Do’s and Don’ts of spray foam. Thanks for the tips on Spray Foam Do’s and Don’ts ! ! !
Every single product I’ve ever used by Loctite has been absolutely incredible. I’m not a paid guy for this and I don’t have any contact directly or indirectly with loctite. I don’t even know where they are located I absolutely love their 3x construction adhesive and fast grab (I used them together)….just terrific. Their thread lockers have always kicked butt ….
No. I have a heater in a condo. They did not finish underneath it. There is two inch between end of heater to floor. Floor has not caulk, or quarter round, or anything. Can I spray there, instead of caulk it (cuz you can’t quite reach caulk gun in there) .. ? The only thing I cannot find online is a picture of how much it expands and if I can use it there. (some sort of slant/fin heater for gas heating)
We have a cold draft coming from under our dishwasher and the cats sitting right in front of it is telling us there’s mice getting in. Would you recommend using this product all along the edges once we pull out the dishwasher? We haven’t taken a look but we felt the cold last year and during the winter the dishwasher malfunctioned a few times due to a frozen pipe(we are pretty sure). Hopefully this insulation will fix both problems?
Good article, BUT as HVAC installer, salesman and duct design and airflow specialist for a total of 30 years, I have learned one thing about complete sealing every crack in your home. It is a bad idea. The intention is to seal every crack to stop outside air infiltration, heat loss and heat gain. While that is a good idea on paper, it is a bad idea for our health. It can create what is called a sick home. Outside air is much healthier than inside air, regardless of the amount of infiltration you have in your home, but no infiltration at all is asking for trouble. You actually want some infiltration especially in a new home that has multiple flora carbons and VOCs that can be dangerous to our respiratory system as well as other reactions. In an attempt to make new homes more energy efficient, they construct them sealing attics, basements and crawlspaces with foam, but this only increases the risk. Some of these are so corrosive they will be drawn into your HVAC system through the return and can corrode the indoor evaporator coil and other metals in your system, so you can imagine what they do to your lungs. This is much worse in a manufactured home because of all the synthetic materials used in them. An older home, especially one made primarily of wood, is much better for your health. In the end, you need some infiltration in your home and a regular airing-out.
I have seen on new homes I was working on they where using cellulose blown in insulation that is shredded newspaper mixed with cement, boric acid, starch, fire retardant, and water. When it dries it’s like a layer of cement. It sticks to the surfaces it’s sprayed on and can even be sprayed and stick onto the plywood on top of the roofing trusses.
I am filling in a gap in the corner of my kitchen next to the window. When they did a remodel for some reason they did not seal the corner. I have been fighting little ants in Spring time. Now I know from perusal this article I can safely use spray foam for this project. I am also going to seal around the gas pipe connection in the floor. I did hit the like button and I subscribed. Thanks!
Was thinking about spraying foam to fill gaps of a newly installed PTL floor of a utility trailer. Want to be able to haul bulk materials and don’t want them falling through the cracks. I figured I could just cut excess off with a shovel. Anybody try this “brilliant” idea, or should I head back to the imagination closet? :> I’m trying to avoid the hassle of putting down plywood / tarps for those hauls.
Hi Aaron. Thanks for the great tips about foam insulation. My main concern is that I’ve had issues with blinds falling off due to poor structural integrity in the ceiling of the window. Unfortunately the gap between the ceiling and the brick wall is only about 2-3 cm. My query is, can I use the foam to fill up the space, then use filler to close the gap and then create a new hole for putting up the blinds again?
my wooden floor is sagging when I walk between supporting 2 x 4s that are laid on the concrete approximately 3 feet apart. I do not know the proper name for those supports so I will refer to them as beams. simply, there are not enough of support beams that are laying on concrete floor, I think they should have laid those supports every foot or so to give it more stability, then put the wooden floor on it. This is a cottage so previous owner did not invest lots of money in quality work. So, because sub-floor is poorly constructed there is a quite of a sag when you step between sub-floor beams, so my question is – can I inject the spray foam between existing floorboards and concrete surface by drilling through the floor boards in order to help stiffen the floor? I am thinking that maybe drilling the holes in the floor on every couple of feet between the supporting beams and injecting the foam will stiffen the floor, then I would lay over this a new hardwood floor. any pros or cons?
is ok to use GAPS N CRACKS spray foam as insulation say after window casing rebuild due to leaky window ac repair, to bugproof my manufactured home because i will be having OTA ANTENNA ALSO GOING THRU THE WALL. i wanna stop bugs n drafts from getting in, BUT TO BE CLEAR NOT JUST ONE SMALL SPOT THE WHOLE WINDOW CASING WHICH ABOUT 12 INCHES HIGH BY 52 WIDE?
Hello, young man, my name is Ms. Virginia. I live in an 1880 farm house I bought 5 years ago and have put almost all my savings into it just as Covid 19 hit. Prices double and then tripled. The contractor I hired; well, I can say they got paid 3x over at the time. I was trying my best to do work myself when I was diagnosed with Stage 3 Non- Hodgkins lymphoma . Question = now that I’m better I find CORNERS were cut!!! My kitchen is an outside wall; the cabinets and drawers floor feel like there’s nothing there!! No wall at all. I know they should have put insulation in the walls because they blown that in!! But I do know that the walls have a divider ? Board in-between the 2×4 centers of that makes sense to you. Apologies for going on.. Truly would appreciate your thoughts or advice. May GOD continue to bless you and your family 😊amen
Gotta love hearing what you’ve already done is a big no-no… I took a can of great stuff and sprayed it into the gap between a cinder block wall and sidewalk, mostly filling large cavities in the wall, then went back and sealed with a concrete/silicon caulk for a watertight seal. Too late to change anything now. The building owner refuses to take responsibility for his building and says it’s fine despite the raise sidewalk allowing water to pour into the building and saturate my equipment.
I recently purchased a can of the locktite window and door foam to replace the fiberglass insulation originally stuffed around an Anderson sliding glass door in my home. It didn’t take long, but my previously perfectly functioning sliding glass door would not open anymore, as the loctite product had bowed the door framing. And when I say it would not open, I mean it would not open! It took a lot of time and effort, using hacksaw blades and other tools to dig and remove the locktite foam from the 2×6 framing, but after its removal the door functioned perfectly again. Further investigation revealed the the locktite product also contained fewer ounces of product in its can than Great Stuff contained, at the same price. I applied the Great Stuff and the door functioned perfectly. YMMV, but IMO, Locktite window & door foam is overpriced junk…
I have a small attic access door that I don’t really need to have open, it’s full of blown in insulation so I can’t really go in it. Figured it would be easier to either use spray foam or maybe the expandable stripping. I’d rather be able to easily cut it open and be able to use the door if needed for leaks.
I watched this article to see what company was doing the spray foam and low and behold….no spray foam company.Can foam is not spray foam,its canned foam.Spray foam is sprayed with a specialized foam macine,an air compressor,and normally a big diesel generator.Its sprayed at temps that can range from 100f to 130f and also needs pressurized air.Can foam is not spray foam,this is a common misconception,canned foam is basically half pound foam which is an open cell foam so it doesnt technically form an air barrier due to the foam being open cell.Though real spray foam(2lb medium to high density)isnt technically a water seal its actually highly more resistant to water than canned foam.Ive seen home made coolers from 2lb foam that hold water for weeks with no leaks.Water will pass right through open cell canned foam.Also if it was sprayfoam you would need a certified spray foam installer to do the work.Just call it what it is,Canned Foam that anyone can use fairly easy
Thank you so much! As a complete newbie to this wondrous foam stuff I was wondering how to clean the tubing before the foam sets. It was your last few sentences that told me! Fortunately I had some lovely stinky acetone handy and managed to save the tube for another day. Also I now know that I can get some more tubes as well. You may be wondering why I didn’t read the instructions on the can. Well I am in Japan and I cannot read Japanese sufficiently well, so your article was really helpful. Thanks again. Liked subscribed.
You can clean out the straws by inserting a bicycle spoke in them before curing, screws in the can openings. And he forgot how to use it for weather sealing doors. Yes, you read that right, secret is to use cling wrap as a release film, first tape a strip of cereal carton cardboard on the edge of the door as a spacer, mist it with water to help the cling wrap adhere. Then with the door closed you fill the crack with the foam and let it cure. It will be difficult to open the first time but then you will have a crack up the 3/4″ filled and a good seal. Paint as you choose, great for a temporary fix or low end housing.
Thanks – I’ve got a gap under a window I’m trying to fill but there’s a uPVC cill that overhangs and then comes down a 90 degrees so I can’t get to the gap in a straight line. Are you able to bend the straws at all or is there a better solution out there? I e had a look but can’t find anything…. Any help would be massively appreciated!
Instead buys a bunch of new straws, buy foam gun – after first use, you never back to straws. You can use foam as well for: – filling space behind plasterboards if they moving – filling deep holes after nails/screws in the wall (way faster then putting filler 2-3 times) – filling spaces behind skirtings (if wall waving) what makes it more durable, and helps prevent cracking of caulk And a lot more…
So in my Man. Door into my garage on the side of the house there is a visible gap under the baseplate of the door jam. Would spray foam be good to use? Also I started noticing a puddle in my basement near where the entrance would be. So you think that since it is not sealed up it it causeing water to leak?
I have a question about spray foam usage. I have a 1790s house – nice thick lath & plaster walls. However, my kitchen was added in later years & my heat runs ~5 as much in the kitchen zone as elsewhere. The kitchen is also exposed on 3 sides with four windows. The walls have loose fiberglass insulation (almost certainly settled at bottom) & are noticeably cold to the touch. I’m getting ready to remove wallpaper & paint the kitchen so patching holes isn’t a problem. Would it be an acceptable solution to drill small holes into each stud space (perhaps at 3′, 6′ & ceiling) & inject expanding foam on top of the loose fiberglass to increase the R value?
Hey I just recently bought a house and in the back yard there’s a janky shed handmade from brick with a tin roof and door. I’d like to be able to store electronics in it however it’s far from weather proof. Would canned spray foam be a good cheap way to weather proof it? I have zero care on how it looks as long as it will protect from rain.
In a few of the DO examples I would either not use the spray foam, or only use it for filling in a larger volume and finishing the surface with something else. Spray foam does not create a weather proof finish. For the windows and doors, the gaps will still need to be covered by a PVC molding, silicone caulking or something else. For small non structural cracks in concrete or wall penetrations in concrete, I would use a cement based acrylic modified sealant or a polyurethane based caulking that can be painted. Visible spray foam looks ugly and deteriorates when exposed to the elements. Spray foam is just like duct tape or electrical tape. In most cases, you should probably use something else.
