Im in commercial construction, been a superintendent for 25 years. The bottom line is to prevent ANY water or air into the structure, by waterproofing, damp proofing, caulking, vapor barrier, etc. As far as insulation, closed cell is the way to go. Have you ever looked at an older home up in the attic, and notice the batt insulation is only 2" thick (or less)? The insulation breaks down and gets into your HVAC system, and you get to breathe that lovely stuff in. Id advise consulting with a commercial builder. Most home builders our a joke, they take way too many short cuts. I hope this helps some one.

Thanks for this wonderful explanation. We are completing a camper van conversion this year, and I just needed confirmation that the full closed cell foam insulation with the false floor installed is the right move, because so many people are using Havelock wool. We may add the more eco-friendly cork wood on top, but we’re definitely choosing the closed cell foam.

I’m so confused 🤷🏼‍♀️ so after video I was thinking closed cell was for me and open cell wasn’t good since I’m building my forever home. But then you said warm climates. So we’re planning a metal home with metal roof and interior wood framing facing south with no trees currently. We want a cathedral ceiling in very large part of home (living space) then above rooms will be a traditional attic. What the best application for me I’m in Texas. I have had different companies tell me different things and what about brands isn’t there different brands?thanks

Steve, Thank you for the informative video. I am a spray foam contractor in northern Wisconsin and have been for 18 years. We offer both open cell and closed cell products and have hundreds of projects sprayed with both open and closed cell foams. Both types are a certified air barrier (4 inches for open cell and at 2 inches for closed cell) that separate warm air from cold air thus eliminating condensation.Mold can not form unless it has moisture and a food source to grow. Both foams effectively stop this process. Both foams also prevent dust and allergens from entering your building. It is true that at 2 inches or more of closed cell foam creates its own vapor barrier and that is a plus. When using open cell you need a minimum of 3 mil plastic for a vapor barrier. However if you are installing drywall over your insulation you can use a vapor barrier primer/paint over your drywall instead of plastic underneath and it does an excellent job.I prefer closed cell but I certainly don't have a problem using open cell. When used correctly both foams are infinitely better than batt or blown insulations for many reasons. Most notably the 40% to 50% savings on your heating and cooling bills. There are many variables to consider when using spray foam but at the end of the day they are both well worth the investment. If anyone has questions feel free to call Jon at Northern Foam Insulators at 715-922-0246. Thanks.

for a container, I'd suggest at least 4" of closed cell, with a very good cooling system and ventilation. I'd also suggest for Costa Rica a secondary "roof" over the container, to block direct sunlight. Even a 1.5" riser with sheet metal will lower the interior temperature considerably. Best of luck on your project.

I've sprayed foams for over 25 years. The claims from closed cell proponents *(which includes this guy) about OC do not "hold water" . It is not the function of insulation to control HUMIDITY inside the structure, let alone stop a leak! If you are getting liquid water or dewpoint under your roof, DON'T BLAME THE INSULATION. -That is the function of the roof integrity, air tightness of the building, and the HVAC system, (no , it's not ventilation, which only depressurizes your structure and is immediately is replaced by humid makeup air from outside.) The key to controlling moisture dewpoint occurrence is to link your attic to the conditioned space, not outside air. Open or closed, both function better than fiberglass because they block the intrusion of outside air, and do a tremendous job of blocking convection within the cavity. Open cell has a very low porosity , and gravity will allow a leak to show itself, but nothing like the fiberous insulations. Closed has zero porosity, but will not stop a leak --- just hide it. Open cell is very good for residential areas in hot, humid climates and dry temperate climates -- anywhere that has lower humidity inside the structure (via: mechanical cooling), than outside on a normal basis. Closed is more suited for colder roofs and situations that have extreme temp. differentials, such as walk in freezers, or the like. This is what causes the confusion, because construction techniques need to actually be different in cold vs warm climates.

Best answer, you win the internet for today. Open cell for West Coast. Spray in Attic, leave vented and at half the cost of Closed cell. Closed cell for East coast. Spray on bottom of roof deck and floor of attic and be able to "control attic venting from 0-100%". In the winter close it up to keep attic warmer and prevent ice damning. In the summer up it up. Everyone in between you have to tweak it to your climate, or pay the difference. FYI for everyone, search open vs closed cell and find Matt Risingers "water test". It shows open cell does not take water on like a sponge. Over 24hr period of standing water it did not soak up anything. A week (like a flood) is a different story.

No longer a threat from tree damage to the asphalt shingles. Quoted by a professional for open cell foam for 3,500 bucks for 28 squares of attic (1,500 sqft living space). Would I be better off with open cell or closed cell against the decking in the attic? I'd like to completely seal the house. He had me concerned about a shingle leak and being able to detect it over closed cell retaining that moisture. Thank you.

Tip: Only use this in vented attics or on old basement walls made of Field stone/River rocks - it should be treated as a last resort. 2 inch foam board has twice the R value and is your best bet for almost any project. NEVER USE THIS ON WOOD REGULARLY EXPOSED TO HIGH LEVELS OF MOISTURE.

lets say there's a 2x4 vertical, exterior stud wall, placed up against a 8" thick existing brick wall, in a 100 year old house. Closed cell is used but there's no need to completely fill the whole wall cavity, so the sides of the studs are foamed in then several inches of foam is laid in between the studs. And the stud wall is dry walled or thin coated with plaster veneer. Water vapor can migrate through the dry wall. Will it condense in the wall cavity? If so then there's going to be a problem, mold could grow on the back side of the wall, the condensed water vapor would collect at the bottom of the cavity and work itself in the floor. Does this all mean that a vapor barrier should be used on all vertical exterior walls? What about the area between the joists between floors, water vapor travels up thru the ceiling, where some it can come into contact with the cold side of the foam and condense? Or will the vapor just keep traveling "up"?

With closed cell, one must be very concerned with trapped moisture. The perm rating for closed cell is so low that water will not pass. Imagine using this on the underside of a roof and you get a leak. The water will now sit on the surface between the decking and the insulation. You will get rot and mold. As a mechanical engineer, I typically will call out closed cell only when it is against a surface, such as metal, where it will not cause rot or mold. If using closed cell, you must take extreme care on making sure the surface next to it will stay dry.

Why would you even consider putting something in your house or any other property for that matter that has even a chance of not doing what its suppossed to do. Mark my words this product is going to lead to thousands of claims in the future where it has been installed in the wrong places.

rich darby i disagree. I think you're confusing insulation with absorption. Wet open cell foam can be effected by air without passing it through. Think of wool clothing for example - it keeps it's insulation when wet, but is certainly able to dry. Having closed cell foam behind a condensing wall/roof leak will hold the water between the foam and wall/sheathing allowing for rot and the growth of mold. With open cell allowing the moisture to enter the vented, hot attic space, it should be just like (in theory) throwing a wool sweater into a dryer. In practice it may work out differently depending on application, installation method and how severe a leak you have.

Any experience diagnosing electrical problems, you’ll need that too. Like working with hot chemicals that constantly plug up your gun? It’s not as plug and play as they promised. How are you with fluid dynamics? That can be the difference between a good job and leaving a toxic mess in someone’s dream home. And then there is always the joy of using a chemical call isocyanate that is highly reactive with moisture and loves to crystallize on the shaves of the pumps and in your lines raising hell with your equipment and ruining your day. So step 1: be a really good mechanic, step 2: be smart and go fix cars, trucks or tractors instead.

I have a metal roof woodshop I want to keep the heat in from a woodstove. I don't care about moisture because the rest of the building is block and very water permeable. I'm thinking open cell would be good for me.

From all of the videos I have seen, water vapor is the culprit. If not dried, it will cause mold growth. The mold smells bad and can cause serious health problems. I have spray foamed my house with closed cell and have no smell problems and it did correct leak issues near windows on exterior walls. The people having odor issues have poor planning of where to foam and no mold issues were resolved BEFORE foaming.

Open cell is preferred for acoustic absorption. Closed cell insulation acts more like a reflector and can transmit some acoustic energy (think of a Newton's Cradle...), while open cell insulation will trap and absorb the energy.

You can do whatever you want, if you spray two inches of closed on the inner/lower and outer/upper (joist) after filling the 4” in between with open cell or even packing peanuts it would save money and insulate further

Can anyone help me? We just paid 3k to close cell spray our small basement. It was sprayed directly onto our stone and mortar walls and cement/plaster walls. Today I took a small pin throughout the walls and just checked to see how thick it was and it is about a quarter of an inch thick throughout. Some spots didn't adhere to the wall. I can push off them and one section of the wall is soft. It's been a week. The rest is hard. Can someone give me any guidance here? I'm concerned it's not thick enough and was sprayed wrong. We live in Pennsylvania. Thank you.

Good Morning! Sorry to hear about the trouble you're having. It sounds to me like you got a bad application - or at least it's bad in some spots. Properly applied foam will stick strongly to the wall. Have you contacted the spray contractor? What is his position on the situation? Please keep me posted on how things go. Email me at steve@stevemaxwell.ca to continue the conversation. Bye for now, Steve

1, the contractor shorted you, and didn't spray what he should have. 2, when spraying the walls, if they had any moisture content or if the walls were not warm, the foam will not stick. And i guarantee its one of the 2. He should have had a heaters down there to heat and pull moisture off the brick..

*79 dead: The Foam Insulation blaze that ripped through the Grenfell Tower, London, causing multiple deaths (79 confirmed / 120+ estimated) has prompted widespread commentary on the Foam Insulation Industry. A Criminal investigation into the Foam Installation Contractors concerned is now taking place. It appears there will be a criminal prosecutions for corporate manslaughter for those concerned whose acts or unsafe products committed the offence. In the case of the Grenfell Tower fire, the most likely prosecution candidates would be the building’s management company, and the insulation contractors and sub-contractors involved in the property refurbishment in which apparently highly flammable foam materials were fitted as insulation.*

I recently had an insulation company at the house. They recommended spraying open cell spray foam insulation directly against the bottom of the roof. Based on your video, it seems like you are saying that moisture in the attic could rise up, pass through hte open cell spray foam, and condense on the wood roof sheething. It would be great if you made a video showing when to not use each kind of insulation. Such a video would help me understand if this contractor's advice was good or bad.

I spray open cell on roof's all the time. Completely fine to do. What people don't realize is there is drywall and paint which makes a vapor barrier, and you will never have a problem. I prefer open cell in attics. Been doing over 10 years in Texas. 👍

You don’t need 3 inches of closed cell to get water and air barrier. Usually only an inch will accomplish this and the R6 rating is misleading as an air tight and water tight space will stay warmer and cooler depending on outside conditions.

Peter Ward only in the presence of moisture, if its installed/applied properly, it (closed cell) will adhere to the surfaces, always use a space maintaining panel against the roof sheathing to allow air movement from the soffit to the ridge vent, even if there aren’t ventilated soffits or a ridge vent, it allows that option, as well as a place for water intrusion to escape, and therefore be noticeable as it drips from the soffit, which rafter bay the leak is in, so it can be easily and immediately repaired. As with anything, it’s all in the knowledge, competency, foresight, preparation and attention to detail by the contractor and technician, that make or break a potentially unprecedented breakthrough, and innovation.

When you insulate a cavity with open cell, there is no air movement. No warm coming to cold, therefore there is no moisture.
@baileylineroad
@baileylineroad 7 жыл бұрын
You're right, there's no air movement through open cell, but there can be (usually is) vapour movement. It's vapour movement that causes most condensation. Airborne water vapour can travel through open cell foam. That's why it's called "open" cell. Open cell has it's uses, but closed cell is the one you can trust to stop vapour migration and condensation in most cases. Thanks for watching. Steve
@richdarby2639
@richdarby2639 7 жыл бұрын
in a cavity you can get what is known as interstitial consensation, this is where condensation forms between the inside of the outside surface and the insulation material , if the insulation is open cell foam it will soak up this condensation and over time create damp, if you use closed cell foam which is inherently water resistant this problem is eliminated from the equation.
