Loved the video and explantion, definitely will consider doing this as i need to change the roofing anyway. Another problem with ventilation is that during winter the "fresh" outside air is often polluted to the point of killing an air purifier filter in a month. (I also don't have a furnace, gas stoves or anything, besides few residents, that would require ventilation)

Makes total sense. If condesation happens at for example 5 celsius, and you make your closed cell foam insulation outside the home, then the outsideof the foam is frozen and the interior is warm, but the 5 celicius is somewhere in the middle of the foam baord, thus eliminating the condenation processes all together.

Good decision! For practical application of the Moisture-Free concept, visit eios.co/

is XPS foam thickness 10cm vapor impermeable? coupled with hollow bricks, should that kind of build be avoided, is that a bad thing, trapping vapor inside the home that i can't go out?

The only material that I know of that is used for insulation that is non-permissive or vapor impermeable is closed cell foam. Structural insulated panels offer a wall system that is air tight and vapor impermeable if installed properly. You could also build a stick built wall with 2 1/2" of foam on both the inside and outside surfaces with regular insulation in between. As long as the foam is contiguous and fully sealed the dew point would always fall within the foam in most climates.

Hey Joel, nice to have your comment. You get the point of avoiding condensation using non-permissive insulation but, the idea is to simplify things, and not to complicate... Two layers of closed cell foam with a permissive insulation in between is a non-sense complication. The base idea of full success is a thermal enclosure made out of a continuous non-permissive insulation with the role of environmental separation and, a structural element to form the building envelope. When those things are accomplished, all building envelope issues are solved. I know, everione worie is about thermal efficiency, but... do not compare non-permissive insulation which is 100% effective, with permissive insulation which have a regular randament of 20% from specified conduction coeficients of laboratory tests. Regarding materials and technology, see eios.co/

DOW Chemical should produce this system and get it into the main stream of construction. Brilliant.

A layer of extruded polystyrene should solve condensation, but it needs to be sealed around and the joints sealed with polyurethane foam, so as air and vapor to not get behind insulation. See installation example from constructions: eios.co/system

So if I understand correctly, you are talking about having a continuous insulation that is a vapor barrier, so that moisture is unable to travel until the location of the dew point? But in that case, the vapor barrier needs to be both on the inside and outside, to handle winter/summer conditions, right?

ST, you get the point, but the terms create confusion! PAC makes use of the terms: continuous applied ’’Vapor Impermeable Insulation’’ and ’’Vapor Impermeable Insulation Assemblies’’ and not Vapor Barrier. To avoid confusion for practice, I named this insulation Non-Permissive. Indeed, when warm vapors don’t get inside of Insulation, where the presumptive dew point is, the condensation is entirely avoided. Instead, vapor barrier, in the form of foils, membranes, coatings, is permeable to vapors (actualized name is ’’vapor retardants’’), and is the prerogative of the moisture control building science. Unfortunately, PAC is not yet taken into consideration for practice. Regarding the both sides, inside and outside, the principle contains the word ’’Viceversa’’ which means that the thermal flow, which coincides with the vapor flow, can be change at any time (climate or season), without affecting the result of the principle (avoiding condensation) but here is another warning of novelty: the envelope wall is conceived as two elements: 1) the Structural Element and 2) the Environmental Separator which creates the thermal-envelope. Mixing the two elements will always cause problems! The Structural Element doesn’t have to be airtight, moisture resistant and thermal isolative, while the Environmental Separator takes all functions of Avoiding Condensation (not controlling moisture), Air-tightness of the building, Waterproofing and Insulation. Now, the Environmental Separator element (the Non-Permissive Insulation) can be applied internal or external to the Structural Element, without affecting the Principle (avoiding condensation is accomplished), and this because is contained in one environment (internal conditioned or external extreme weather) and the action of vapor and difference of temperature will take place inside of the Vapor-Impermeable, non-permissive Insulation. Of course, if the Structural Element is in the exterior environment (non-permissive insulation applied internal), it needs to be protected by exterior weather. This is why, internal application of non-permissive insulation is recommended on mansards and ceilings at the last floor (the Structural element is protected by the roof system). For practice, you can find more on eios.co/moisture-free-concept or ask here.

Mario, Dew Point is the temperature on which vapor reverts to water, and condensation occurs, and depends on temperature and Relative Humidity. Usually, interstitial (in wall) condensation occurs because of vapor diffusion and air-transported vapor inside of wall, and the dew point generated by outside cold. The Principle states that vapors will not get to the dew point inside of insulation, so as condensation is avoided. Anyway, your comment is very funny, thanks!

Interstitial (in-wall) condensation depends more on the vapor-permeability of walls and insulation (whish usually is very permeable), and on the temperature-difference between inside and outside, and not too much on the insulation thickness. The temperature difference creates vapor diffusion and dew point. There is no need of VB in the avoiding condensation concept which provides zero-condensation by stopping vapor passing through the insulation, and not retarding vapor passing through walls using vapor barriers. VB is the "appanage" of the moisture controll building science. Avoiding condensation stipulated in the Principle doesn't depend on climate or season!

I have a problem with moisture in my basement. The West and North walls of the basement are about 8 feet/2 meters below grade. These walls as well as the floors are constantly moist and anything that can mold will if in the basement long enough. Since it is below grade I cannot insulate from the outside. My house is stone and is over 100 years old. The walls are about 2 ft thick. Would it be possible to insulate from the inside? I have played with the idea of building a new inner (non structural but built with bricks) wall with closed cell foam insulation between the 2 walls. The outer wall effectively becomes part of the earth and would be constantly moist while remaining at earth temperature and the inner wall would be dry at inside temps and the foam would stop any moisture transfer. Can anyone give me their thoughts and /or advice on this. The South and East walls are above grade and do not have these issues.

You probably have water infiltration and capillarity issues, not a condensation problem. Make a waterproofing layer, preferably cementitious, on walls and floor. Than you can insulate non-permissive with XPS insulation on walls, apply cementitious plaster reinforced with mesh, or build a brick wall. Do not perforate with anything the waterproofing layer! I recommend to make the waterproofing, and wait some time to see the results. Good luck with your project.

Avoiding condensation is possible only by creating a vapor-impermeable insulation enclosure, or in the new terms, "the non-permissive thermal enclosure". This have nothing to do with the vapor-barrier, renamed vapor-retardant barrier, in the form of foil, membranes or as you say, paints. If those barriers are involved in the envelope wall construction, will not influence vapor diffusion and condensation, such are kept in one environment (the inside warm environment). This explainer is only "the top of the iceberg" of the new science of Avoiding Condensation, and because of this, many confusions will be made with the science of Moisture-Control, which is based vapor barriers in the form of foils, membranes or paint.

Thanks for your comment. Your concern is a big confusion of the whole construction field. I'll explain: vapor content in the air is an environmental specific, and is expressed by the Relative Humidity, which depends on environmental temperature. Most of the time, outside RH goes above 80%, but condensation occurs only in the clouds, where rain starts, or morning dew. Inside of buildings built according to this principle, RH is usually in the comfort range of 35 to 65% RH, but if there is an extra source of vapors, RH can go to 99% RH and condensation is still non an issue. The confusion is that, in excess vapors in the interior environment needs to be ventilated naturally by windows/doors or mechanically, and this is not the duty of envelope walls. Vapors gets in the walls because of the temperature difference, and this is also the cause of condensation (dew point inside the wall). The principle gives the option to separate two environments, with two different temperature and RH, without the condensation and moisture issues of the enclosure that separates those two environments. For your trust, no building made according to this principle reports any RH above comfort, no matter the inside activity.

Dear @priya85746, there is a thermal bridge problem. You can solve this problem by non-permissive insulating the ceiling using 5 cm (two inchs) or more, embossed extruded polistirene XPS, sticked and sealed with poliurethane foam. See this system: eios.co/inside You have to find a solution to prepare the ceiling surface for adhesion and to fasten every board up to curing the poliurethane foam adhesive (also see this page eios.co/system). You can also build a metal frame with a layer of OSB to easily install the insulation system. This insulation will solve the condensation problem on the ceiling surface, and behind insulation, and will also save you a lot of heat energy that goes through the concrete slab to your neighbors above, in the cold season.

The insulation used is the XPS extruded polystyrene, which is considered vapor-impermeable for a thickness more than 2 inches (5 cm). Vapor barriers are now called vapor-retardant barriers and yes, do allow vapors to pass from the concept. The principle refers to an enclosure, so the insulation material needs to be assembled to create a vapor proof insulation for the whole building, or element of the building. See eios.co/system and eios.co/sky . This assembly is called Non-Permissive insulation, is moisture-free, and is also 100% Effective insulation, which means that it applies entirely the testing coefficients as conductivity [W/mK] or R-value. Other air-permeable insulations applies to the building just a small % of the specified testing conductivity. The decreasing of the real R-value of the air-permeable insulation assemblies is directly proportional with the temperature-difference, which means that, wen we need insulation the most, we have effective-insulation the less.

Insulation is usually the most air/vapor permeable material used in construction, without considering the less airtight installing. The cladding is responsible by rain water getting in walls through holes, if you refer to that. The Principle is all about using vapor-impermeable insulation materials, continuous installed and sealed to create an enclosure, the insulation itself, not in combination with the frame. And Yes, mineral walls functions on a different principle, by accumulating moisture on a cold season (they are a good water reservoir), and releasing water on the warm season. But anyway, think about roofs, living attic, ceiling at the last floor, not everything can be made out of brick. And trust me, construction made according to this Principle, is made to last.

So it seems to me like basically you're talking about a perfect insulating material. What you describe is essentially the Tyvek layer of a building envelope. The problem is there is no such thing as a perfect insulation. So no matter what there's going to be some heat transfer One Direction or the other. Not only that but you're missing the point of windows which is the biggest place where condensate happens and really the only place I've ever seen it actually turn into any sort of puddle or problem. I've been in a muggy attic or two but I've never seen one that actually accumulated water only window sills. no walls no basements, nothing else I've seen will develop actual puddles. I've seen some brick in basements get damp but never cause standing water from vapor. If you were to Vapor coat your insulation bats the only thing that you would possibly do is prevent the air transfer before the wooden sheathing instead of after. Even then I've really only seen this in places where they have been building airtight for a long time that have major temperature fluctuations like Alaska I've never really seen mold caused by air Vapor transmission only by other sources like leaky pipes or groundwater seepage or bad drainage or bathrooms that don't have proper ventilation I suppose that could technically be thought of as a vapor problem now the problem with build airtight building envelopes or what you're talking about with airtight insulation is that eventually one way or the other you're going to get temperature fluctuations that do cause some kind of vapor transmission within the home now when you have airtight building envelope that Vapor never leaves so it can't go anywhere and it's just accumulates so you get more problems with building airtight than you do without you want to be able to let that vapor go rather than accumulate it like a collection

The Non-Permissive thermal envelope is proved moisture-free from more than 10 years so far. The principle applies mostly for Non-Mineral, Moisture Sensitive construction such as wood or metal structured walls.

The exterior insulation foam panels you promote are still held in place by big wide strips of wood (such as on top of a roof deck), which means there is actually no continuous condensation seperation as you claim... wood attached to wood attached to drywall or roofing tiles does not insulate or stop moisture. Of course without the wood elements, you could not attach a roof on top of foam panels, since foam isn't a structural material. So you haven't actually created a system that matches your theory. To follow your theory you could live in a big styrofoam cooler, but the styrofoam would break easily which is why we don't make houses to be styrofoam boxes. Also lots of homes are made with a few inches of rigid foam insulation outside of the wood framing these days, especially in very cold climates... you haven't actually "invented" anything, much less a perfect enclosure with your "system".

Yes but... Contractors and designers don't follow this principle because is not yet acknowledged in the state of the art. When will be, moisture-free construction needs to be a must. Who knows when...

Min. 5,31: "......eliminating Dew point entirely"..... Really ? How can you ELIMINATE an interaction ? I am very curious to find out how you block a changeover to happen, or how you can make conversions vanish.....you either found another law of thermodynamics, in which case you should be proposed to the Nobel prize in physics in case you bother to come up with some hard evidence to back up your allegations, or you simply mistake some very basic pressure/temperature/volume ratios for whishful thinking......

Dear Mihail, the dewpoint of the interior space, considered warmer than the exterior environment, or vice versa, theoretically exists, and is a variable temperature, depending on various factors, in principal Relative Humidity and temperature. The idea of the principle is that, this dewpoint is situated always inside of a vapor-impermeable insulation. The dewpoint temperature of the inside warm vapors can be anywhere inside of this non-permissive insulation, detached from the inner surface (which needs to be warmed up by the interior heat). The non-permissive insulation needs to resist only to the theoretical differential vapor-pressure between inside warm vapors and external cold vapors. Usually, this vapor-pressure is not quite a significalt action, such warm vapors does not get in contact with cold vapors or cold areas inside of this insulation. A simple idea that functions perfectly, and saves construction from tons of condensation water/building annually. The only problem is: this humanity needs to understand that is very easy to implement this principle in practice, with the only need to change its mentality, from moisture-control to avoiding-condensation. All physics laws will remain in place, as before Archimedes and everybody else.

@@mariusradoane1787 We are talking about different things.

Who is your audience? I can tell you it's not me. Despite an excellent vocabulary and a bent towards the scientific I found your video to be frustratingly over-loaded with language not useful for translating your concept into action. Exactly what type of product actually accomplishes what you recommend? What comes close? What doesn't? Your video was not a good investment of my time, even if the information presented is vital and accurate. You should consider a rewrite that translates into more useful parlance.

Indeed, this is not an insulation product. Is the very base of a new building science named Avoiding Condensation, which intends to replace the current Moisture Control science of managing damp in building envelope walls. The first and only product based on this principle is eios.co/ On KZreads like this kzread.info/dash/bejne/iY19j9qeYJy2fMY.html

I am with you.

get to the point and avoid the corny intros

Except it's all plastic rubbish. Breathable walls insulated by natural fibre, which can freely let moisture pass through are the go.

The good thing is, the structural element can be as breathable and natural you want. The bad thing is that breathable, natural insulation let vapors to pass, and many times lets to pass direct heat by convection (less airtightness) or absorbed water. This means a lot of water. Bio materials will be eated by organisms growed by moisture. The principle allows to build the structure with natural materials, protected moisture-free by a synthetical thermal envelope.
