If you have any questions, please contact us anytime. Thanks for the response. Based on what I gather from sifting through in your articles and our experience, it sounds like this is just not a good approach - for starters, I'm not sure how the cost of spray foam cancels out the cost of an additional 1" of rigid insulation, and secondly we would be isolating the cdx sheathing between two impermeable layers. Charlie and Malcolm, We've broken down our insulation equipment by category so you can easily build out your spray foam systems. Why you might choose to use spray foam inside a metal building even though the interior is not heated or cooled. FROTH-PAK. One nit to pick is that the cellulose was blown in ~4" holes (on the interior OSB side) with a large hose, not with dense-packing hoses, and thus probably not at a density sufficient to eliminate settling over time. closed cell followed by open cell A gallon of mineral oil can be ordered from chemical suppliers for around $25.00. Flash and batt is better but doesn't solve the thermal bridging problem. Note the Icynene open cell foam does not hold moisture in walls or attic assemblies. Spencer Forge & Manufacturing in Spencer, Ohio, West Roofing Systems installed spray foam over a metal roof at the. This adds strength to the roofing system and also gives it some stability because silicone coating on its own is very slippery. The R-value is based on the air space between HY-Fi and the spray foam. Yes I should have given the temperature in the basement: about 64 in winter and 72 in summer. In Zone 6, a 2x4 wall needs at least R-7.5 for the exterior foam layer. In a 24 wall, the installer will usually stop at a maximum depth of about 3 inches instead of 3.5 inches, leaving the typical bumpy surface of cured foam. Target a wet foam application thickness of 1/3" as that will expand to one inch cured. Note that not all spray polyurethane foams require thermal or ignition barriers. When you use open-cell spray foam, the R-value is R-8.5. If you want to leave a gap between the logs and your 2x4 stud wall, to allow room for spray foam between the logs and the 2x4s, then the larger the gap, the better. Or will the gap in r-value between the foams still remain low enough that I should still consider open cell to the face? Next, spray polyurethane foam is applied to the roof surface at a minimum thickness of 1 inch, although it can be sprayed at greater thicknesses to increase insulation value. UK Level 6 construction is all about sustainability, and it's fair to say that fiberboard & cellulose are far more sustainable than foam insulation. Protective measures must be employed to minimize risks associated with exposure through inhalation, skin and eye contact. The material acts as a high-performance thermal, air and moisture barrier. We use both open cell foam and closed cell foam. Follow the links below or give us a call on 02 9898 0751 and we'll be happy to give you a hand! With that approach, it does seem that thermal bridging through the studs makes them a potential condensation point, so that would seem to require exterior continuous insulation.

Throughout the years they have made significant improvements and reformulations and is now one of the leading insulation types worldwide used in shops, barns, houses - you name it. Even if it were entirely based on the building footprint, increasing the depth of the walls by an inch would for the average house would equate to about 12 sq. Or did you mean to write "dehumidifier"? In Nebraska the county assessor comes unto the property with a tape measure and records the outside dimensions of the footprint, 1x4 corner board trim lines to the other 1x4 trim board to record the footprint in feet/inches. This calculation is close enough for the discussion at hand, but there are a few other fine points that quibblers will note -- namely, the contributions of interior drywall, exterior sheathing, siding, and air films on the interior and the exterior of the wall. The Center for the Polyurethanes Industry (CPI) offers guidance to contractors and builders handing spray foam.

It cures around 1-2 inches in thickness. Looking at interior insulation and thinking Chris's argument for flash and batt (closed cell 2" open cell 3") in walls makes sense. I recommend running from any company that preaches only the virtues of closed cell foam. I am reading this as an being old post but Yes to the footprint question. The thermal bridging through your 2x6 wall studs tends to undermine any advantage from using spray foam between the studs -- as noted in the article above -- so I would recommend cellulose. Reduces air leakage and air-infiltration. for pricing and availability. Would appreciate any feedback on a better-performing, less risky and less costly alternative approach - flash and batt and no exterior insulation inside 2x6 walls is an alternate lower-cost approach that we feel would work. So what is the convensional wisdom regarding TJI framing factor?Worst case scenario is a 3.5" flange at top and bottom and a 3/8" flange? There are a couple of different kinds of coating. Contractors are reporting exceptional yield, 8,000-9,000 board ft, compared to traditional 2.0 closed cell insulation. Just one more way that this issue is a bit trickier for ceiling applications.

John, With closed-cell spray foam, the exposed sides of the studs (the portions that extend inwards beyond the 3 inches of foam) make the thermal bridging penalty worse. Nicolaas, If we need to install two inches of foam versus installing four inches of foam, thatll affect the cost. This is part of why I personally like the idea of flash-and-batt more. With open-cell spray foam, the sides of the studs (above) are not as exposed as they are in a wall insulated with closed-cell spray foam (below), and this fact reduces the thermal bridging penalty. As much as I think it necessary for the code to change, I need to get this reno done so my mother has a place to live and it seems a poor political move for me, at this moment, to argue that poly is unnecessary and something less permeable would be better for a basement application. Are there any other similar techniques ? I would stick with cellulose/ fiberglass between studs, and 2 inches of EPS or polysio on the exterior. So humidity paranoid I am that I was evening planning to do double stud walls to assure an intact vapor barrier. 1400 Hz. Thank you.

But where/when that band-aid becomes necessary (often the case in retrofits, or where the architect went nuts on new construction creating 1001 different roof planes to scratch some bizarre aesthetic itch) using the LEAST amount of closed cell foam required for getting the job done is being much nicer to the planet (and usually your wallet.). Pros: 1 thick spray foam has an initial R-value of 7.2 per inch and R-value of 12 at 2 thick. These include spray zone containment, adequate ventilation during installation, safety training (for all involved in installation), use of personal protective equipment (PPE), such as fullbody suit and headsock covering skin, along with nitrile gloves and eye protection for full installation duration as well as a medical surveillance program for field crews. If you want to install spray foam in a stud wall, and price is no object, then it would seem to make sense to specify closed-cell spray foam, right?

While 1/2-inch gypsum in the walls and ceilings, or 3/4-inch plywood subfloor, prescriptively meets this requirement, other applications of foam may require application of an approved thermal barrier covering or coating. If it's only happening in the days following a rain and independent of out door dew point temps there could be moisture loading up in the sheathing due to improper or inadequate drainage between the clapboards & sheathing. The amount of foam you really NEED in a new home design is pretty small (if any), and going without doesn't necessarily have to be more expensive or lower performance. Its a good cost-effective solution to any metal roof. This will cost a little bit less than a spray foam roof, but theres no R-value involved with a coating system. Because of the magnitude and multiple uses of the facility, installation proved complicated. The trimmed out overspray filled an ENTIRE 10 yard dumpster.
