Log in UPDATED on April 5, 2016Most green builders who need a layer of horizontal insulation under a concrete slab specify expanded polystyrene (EPS), an affordable product that performs well in this application. If a builder specifies high-density EPS rated for below-grade use, the product is very durable.That said, many green builders don’t like EPS. Some object to the fact that polystyrene is made from petroleum, while others worry about possible health problems associated with the brominated flame retardants that polystyrene manufacturers add to EPS.These builders have always wished there was a good, affordable way to insulate concrete slabs without the use of foam.Mineral wool insulation is available in several different forms. Some builders have looked at the densest available mineral wool panels and wondered, “Are these insulation panels dense enough to install under a slab?” When asked that question, mineral wool manufacturers have usually answered “no” — at least until the last few months.A couple of years ago, I asked Iain Stuart, a technical solutions coordinator at Roxul, about using Roxul under concrete slabs. Stuart told me flatly that Roxul insulation products were “not for horizontal use under slabs.”After several years of dithering, however, the engineers at Roxul, a manufacturer of mineral wool insulation, recently gave builders the OK to use horizontal mineral wool insulation under concrete slabs.The first sign that Roxul was ready to change its public position came last fall. In the November 2014 issue of Environmental Building News, former editor Alex Wilson shared the news that a Roxul representative at a Passive House conference in Portland, Maine, announced that the company would “stand behind” the use of Roxul mineral wool insulation installed horizontally under slabs.Ever since Wilson shared that news, I’ve been waiting to see whether the oral announcement by a Roxul representative…
How to Design a WallHow Risky Is Cold OSB Wall Sheathing? Calculating the Minimum Thickness of Rigid Foam SheathingVapor Retarders and Vapor BarriersRigid Foam Choices Installing Mineral Wool Insulation Over Exterior Wall SheathingInstalling Roxul Mineral Wool on Exterior Walls RELATED ARTICLES Choosing the best exterior insulationWith those decisions made, what should we use for exterior insulation? The most common exterior insulation is rigid foam, either XPS (extruded polystyrene) or polyisocyanurate (PIC). A third option is EPS (expanded polystyrene).Although my feeling is that foam insulation is probably the best use for oil, in debating what materials to use, I argued strongly against XPS. XPS’s blowing agents are nasty — they stay in the atmosphere, and even though XPS insulation saves energy, in terms of global warming potential, XPS is usually a net loss to the planet, according to research by David White. Additionally, as XPS ages, its R-value decreases, and at useful thicknesses, it’s fairly effective at blocking the ability of the wall to dry to the exterior. In the plus category, it’s readily available, has decent compressive strength, and is easy to work with. Until the industry changes to the more benign blowing agents used for XPS in Europe, though, it’s always my last choice for insulation.Roxul ComfortBoard ISPolyiso has fairly benign, pentane-based blowing agents, and it is advertised as having a high R-value per inch, but with its usual foil facing, it is a total vapor barrier. Not only does its R-value decline over time, but it also loses performance as the temperature drops, just when you need it the most.EPS is vapor semipermeable at thicknesses less than 3 inches, has relatively safe blowing agents, and stable R-value, plus it’s generally less expensive than the other options. It can be crumbly to work with, and it shares with XPS a brominated flame retardant that is not safe to ingest, but if I had to choose a foam, my first choice would be EPS. My second choice would be polyiso.Fortunately, there is an alternative that is good for the house and good for the planet: rigid mineral wool, in the form of Roxul ComfortBoard IS (the IS is for “insulating sheathing”). It will keep the sheathing warm and dry, and it has low global warming potential and stable R-values. It’s a lot like a wearing a wool coat compared to a rain slicker. It’s a bit of a pain to install compared to the other options, but it’s completely vapor-open. Not only will it allow the occasional raindrop that finds its way past the siding to drain freely, but it will let the wall sheathing dry to the exterior if and when it needs to. Installed with 1x strapping, it makes an excellent ventilated rainscreen that is open to air movement at both the top and bottom of the wall.Considering my obsession with managing water and water vapor and my strong desire to build resilient yet energy-efficient homes, I am happy with the ProHOME wall assembly. Editor’s note: This post originally was published as part of the ProHOME series at Fine Homebuilding magazine. Michael Maines is a Certified Passive House Consultant and residential designer based in Palermo, Maine. Detailing for Climate Zone 5To meet code requirements for limiting vapor transmission by diffusion into the wall in Climate Zone 5, we needed a Class 1 or Class 2 vapor retarder on the interior, but with at least R-7.5 exterior insulation, the code allows a Class 3 vapor retarder. (Class 1 is 0.1 perm or less; Class 2 is from 0.1 to 1.0 perms; Class 3 is from 1.0 to 10.0 perms. Over 10 perms is considered vapor-open.)CertainTeed is now selling kraft-faced batts with its vapor-variable MemBrain vapor retarder adhered to the kraft paper. The MemBrain normally blocks most water vapor diffusion as a Class 2 vapor retarder, but when the relative humidity reaches about 60% (when bad things can happen), it opens up to be vapor-open, allowing the wall to dry to the interior. With airtight sheathing, vapor movement by diffusion is not considered to be a major issue by prominent building scientists, but the MemBrain gives us insurance.If we needed a functional air barrier at the interior, as some builders try to do with poly sheeting, then MemBrain in sheet form would be a better choice. Because we are using Huber’s Zip System oriented strand board (OSB) sheathing as the airtight layer for the walls, we don’t need to worry about the interior of the walls being perfectly airtight, although there would be no harm if it were a second airtight layer.Zip System sheathing is denser and more airtight than regular OSB (I learned that the hard way on a Passive House project), and Zip’s tape system is now familiar to most contractors. Like other OSB products, though, it is more sensitive to moisture than materials such as plywood or solid lumber. That doesn’t mean it’s a bad product; just that moisture control needs to be considered when using any OSB.The phenolic coating on Zip sheds liquid water effectively and is open to water vapor. Huber does not publish data for the actual vapor permeance of its sheathing, but standard OSB is usually between 1.0 and 2.0 perms, with some third-party testing finding that Zip is below 1.0 perm. The permeability of OSB and plywood sheathing varies with relative humidity, so it’s hard to pin down. In any case, the Zip panel can be assumed to be borderline between a Class 2 and Class 3 vapor retarder, meaning that it will allow water vapor to pass through, albeit at a slow rate. If the sheathing temperature is below the dew point of the air, the water vapor will condense out of the air and onto the surface of the OSB. Capillary action will then draw the moisture into the OSB. Exterior insulation protects the sheathingTo reduce the chances of the OSB becoming saturated, our main defense is to keep air from flowing through the assembly, which we’ve already covered. The next defense is to keep the sheathing above the dew point by installing continuous exterior insulation. One of the key details of a wall with exterior insulation in Climate Zones 3 and higher is to make sure the proportion of exterior to interior R-value is high enough to prevent condensation most of the year. The exterior insulation keeps the sheathing warmer than the outdoor air, but insulation slows heat flow in both directions, so the cavity insulation keeps indoor heat from reaching the sheathing.The 2012 IRC has a handy way to make sure the sheathing stays above the dew point most of the year: table R402.1.1, which shows the minimum R-value of cavity and exterior insulation. [Editor’s note: Strictly speaking, the previous sentence is inaccurate. For more information on this topic, see Comments #10 and #11, below, as well as a GBA article titled The 2012 Code Encourages Risky Wall Strategies.] For Rhode Island (Zone 5), it’s 13 + 5. In other words, a minimum of R-13 cavity insulation with a minimum of R-5 exterior insulation. What’s not clear from that table is that if you increase the levels of insulation, it’s very important to keep the proportional relationship the same, or to err on the side of additional exterior insulation. You can’t just keep code-minimum R-5 exterior insulation and bump the cavity insulation up to R-21; if you do, the sheathing will be too cold during a typical winter and condensation will occur.For Zone 5, the relationship is 38% exterior to 62% cavity. We have R-21 cavity, which means that we need at least R-8 exterior insulation to control condensation. Table R702.7.1 supports this math, requiring at least R-7.5 for a 2×6 wall if you want to use a Class 3 interior vapor retarder.We could have installed more exterior insulation; from an energy use point of view, more insulation is always better, but there are diminishing returns. Energy modeling showed that going from 2 inches to 4 inches of exterior insulation would save about 250kwh/year — less than $40 worth of electricity and less than the annual output of a single PV panel. I have designed Passive Houses with R-40 exterior insulation, so I’m not afraid of using too much, but considering the added expense and hassle of installing thicker rigid insulation, we opted to stick with 2 inches. At R-8 for the 2-inch thickness, we meet condensation-control requirements. When installed over an otherwise conventionally framed wall (or a wall built using advanced framing), continuous exterior insulation, also known as insulating sheathing, is a great way to improve whole-wall R-values and to keep the framing and sheathing dry. There are some tricks to choosing size and type of materials, though.Depending on the situation, I use different wall systems. For low-energy new construction, the builders I work with often prefer either double-stud walls with cellulose insulation, or Larson-truss type outriggers with infill insulation over a standard stud wall. Both can work well, but they have their downsides, including cost, wall thickness, and water-vapor management. Many builders, including Mike Guertin, prefer continuous exterior insulation. Since builders seem to have strong opinions on which wall type they prefer, and I think they can all work fine if designed and detailed well, I worked with Mike to design a durable, efficient wall detail at the ProHOME.The wall is framed with 2x6s 24 inches on center and insulated with fiberglass batts. The R-value of fiberglass batts is typically a bit more than that of cellulose and a bit less than mineral wool, but they’re all pretty similar. I have to say that fiberglass batts are rarely my first choice for insulation, but they are readily available and inexpensive, and in the right conditions — installed tightly in an airtight cavity with limited temperature differential across the batts — they can perform as intended. (The common assumption that they should not be compressed is wrong; if you compress them, their R-value per inch increases, up to a point.) It’s important to have at least one really good air barrier somewhere in the wall assembly. It’s OK to have more than one air barrier, but it’s never OK to have more than one vapor barrier. I prefer to use vapor retarders rather than vapor barriers, as I’ll describe below. Air barriers and vapor barriers (or vapor retarders) can be one product that does double duty, or they can be dedicated layers. For the ProHOME, we are using one air barrier and two vapor retarders (the sheathing is acting as both a vapor retarder and the principal air barrier).

Kolkata: Trinamool Congress has written to the Election Commission of India (ECI), protesting against BJP for engaging wrestler the Great Khali during an election campaign in favour of Anupam Hazra, who is contesting from the Jadavpur Lok Sabha seat on the saffron party’s ticket.A complaint lodged with the Chief Electoral Officer (CEO) raised questions on how a foreign national can take part election campaign for Hazra. The complaint also alleged that BJP is trying to influence the electors by using Khali, who is a national of the United States of America. The wrestler campaigned for Hazra on April 26. Also Read – Bengal family worships Muslim girl as Goddess Durga in Kumari Puja”He (Khali) holds a US citizenship. Therefore, a foreigner shouldn’t be allowed to influence the minds of Indian electors,” reads the complaint. The complaint also says; “Dalip Singh Rana, who is known by the name the Great Khali, was seen campaigning for Anupam Hazra, the BJP candidate from Jadavpur. He was seen campaigning from an open top jeep on the streets of Jadavpur. Rana is not an Indian citizen and holds citizenship under the United States of America. BJP is using Rana’s celebrity status to misguide Indian voters.” Also Read – Bengal civic volunteer dies in road mishap on national highwayIt is also mentioned in the complaint that Khali gave an interview saying that he would be present for Hazra whenever he would be called in. “I have specially come from America to support my younger brother. He is filing his nomination papers. I want to request everyone to cast their votes for him. Do not waste your votes. Anupam is a learned man and he knows your troubles and will be able to serve you better than anyone else,” Khali was quoted in the complaint. During his campaign, Hazra said that Khali is a popular global youth icon and many of his supporters had requested him to do something exceptional. Hence, he thought it was a unique platform to bring in the popular wrestler. The letter alleged that BJP is desperate to win the elections by any means possible. In this case, utilising the help of a non-citizen who has no information about the intricacies of Indian politics or what may be the best option for the Indian electors. Trinamool urged the Election Commission to take action against the BJP candidate in this regard. Additional CEO Sanjay Basu said that they have received the complaint and an inquiry is being conducted into the incident. “We will comment on the issue after we receive a report in this regard,” he added.
Mumbai: In one of its largest hiring exercise since it began operations over three years back, the premium carrier Vistara is hiring around 500–100 pilots and 400 cabin crew–mostly from the grounded Jet Airways, say industry and airline sources. The grounding of Jet has come as an opportunity for the market to hire readily-available skilled workforce from the licenced categories–pilots, engineers and cabin crew–and deploy them directly into specifics roles, thereby saving time and money on training them, they said. Also Read – Commercial vehicle sales to remain subdued in current fiscal: IcraAfter unsuccessfully looking for an investor or fresh bank loans for months, Jet Airways had finally on April 17 stopped operations, leaving over 22,000 employees in the lurch. Of these around 1,300 are pilots and over 2,000 are cabin crew. Tuesday was the last day of the two-day recruitment drive for the cabin crew at the Tatas-Singapore Airline-run Vistara, which took place simultaneously in Mumbai and Gurugram, they said. “Vistara, which is likely to begin international operations soon, is in the process of inducting 100 pilots besides 400 cabin crew. Most of the new workforce is expected to come from the grounded carrier Jet,” said a source. A Vistara spokesperson was not available to comment.
Mumbai: The benchmark BSE Sensex extended its losing streak by falling over 250 points in early trade Wednesday, led by losses global markets amid rising US-China tension.

Top losers in early session were RIL, ONGC, Vedanta, NTPC, Bajaj Auto, Bajaj Finance, HDFC twins, HUL and SBI, shedding up to 1.57 per cent. On the other hand, Bharti Airtel, PowerGrid, IndusInd Bank, ICICI Bank, Tata Steel, Yes Bank and Sun Pharma were the top gainers, rising up to 0.82 per cent. In the previous session on Monday, the BSE bourse ended 323.71 points, or 0.84 per cent, lower at 38,276.63. The NSE Nifty too dropped 100.35 points to settle below the 11,500 level at 11,497.90.
Laayoune – Public authorities dispersed,Tuesday in Laayoune, an unauthorized gathering of forty women led by a group of topless Spanish women. These behaviors have sparked the disapproval and indignation of the population, as being shocking and a breach of the traditions and values of Moroccan society, said a statement from the province of Laayoune.
Rabat- With a matchless spontaneity and an even more commendable honesty, the Algerian singer Khaled said that he supports the candidacy of Abdelaziz Bouteflika for a fourth term, despite all the demonstrations and protests that the country is facing.“At least, with Bouteflika, you can now go out with friends and go in palaces in Algeria,” Khaled said. “You can order a glass of whiskey and drink it. I must say it in the clearest and the most sincerely way of the world.” Khaled doesn’t support the sick candidate for a fourth term because he has a convincing political, economic and social program… No. He supports him because thanks to Bouteflika, he can drink alcohol in public places. This makes Bouteflika a popular candidate because he defends a particular lifestyle based on individual freedom and an open society. The people in Algeria fear these freedoms will evaporate if the president is not reelected.What Khaled said, spontaneously and frankly, is an opinion shared by the Maghreb and Arab elites who avoid declaring this support openly themselves. These people are afraid to see the fundamentalists coming: the great opponents of whiskey in front of (and on behalf of) the Lord– the great enemies of a liberal life.These elites are fighting against any democratic changes in our societies. They fear to see the bearded take positions of power with the hopes to remove certain benefits and freedoms. They hide behind slogans, ideas and attitudes that don’t accurately reflect their fears for their personal freedom, provided by despotic regimes led by secular elites (socialist, liberal or nationalist). So, the secular in our country are struggling against democracy because it could bring in the Islamists. But the latter, unfortunately, represent the majority in these conservative societies.Groups aim to be dictatorial because their despotism is political. The Islamists despotism affects the societal norm, impacting daily routines and personal choices. As between two evils, namely two dictatorships, you need to choose the lesser. Then go with the seculars… So how can we move away from this system that only offers autocratic government or an opposition that is just as much autocratic?There is, of course, a solution, that can be valid only if we consider as a mistake to have to choose between these two camps. What secular and Islamists have retained from democracy is the power of the ballot box, that allows the majority, the day after the elections, to dominate a minority. And this is a serious mistake.Democracy is a package of principles, rules and practices including: protection of individual freedoms, separation and balance of powers, freedom of the press, and rights for minorities…. The system that defends the right of minorities is always democracy, not absolutism.An elected government has no right to ban someone from drinking alcohol, a woman from going to the beach or a girl from wearing jeans. This comes, indeed, under the individual freedoms. People who know their freedoms and the meaning of democracy can’t accept the guardianship or autocracy, even if it’s religious. This is true that in Afghanistan, Sudan or Iran, a particular way of life is imposed by the political powers by force. But they arrived at the head of their country by violence, coup, revolution, and armed conflict. Not in a democratic way.A large part of the political, cultural and media elites fears or feared the Arab Spring, and didn’t support the enthusiasm of young people in their respective countries for democracy. These elites feared for their lifestyles and finally chose autocracy and despotism instead of freedom and liberalism.Translated by Nahla Landoulsi. Edited by Saba Naseem
We’re on the ground in Rio covering the 2016 Summer Olympics.So far in these Olympics, the 19-year-old freestyle swimming sensation Katie Ledecky has won four medals for the U.S., three of them gold, and shattered the 400-meter world record in stunning fashion. She has just one event left in these games, and it’s the one that rocketed her to prominence in 2012: the 800-meter freestyle. She swam a leisurely 8:12.86 in her qualifying heat on Thursday, which is both an Olympic record and faster than any other woman has ever swum this distance. A repeat swim in the final would assure her a gold medal.Ledecky’s world record in this event — set somewhat unexpectedly at the Arena Pro Swim Series in January in Austin — is 8:06.68. Even before these Olympics began, people have started to wonder whether she might — someday — be able to achieve the unthinkable: Ledecky tends to pace herself about a half-second faster (per 50 meters) in the 400. She swam the middle lengths of her pre-Olympics 400 record in an average of 30.2 seconds, compared with 30.7 in her 800-meter record. If she follows a similar pattern this time, she’ll need to approximately match that 30.2 — which she can do by essentially swimming exactly her 400-meter race, plus an extra 400 meters in the middle at around 30.4 seconds — barely slower than her worst split in that event of 30.3.This is a tall order, indeed. But there are reasons to think it’s not impossible. Ledecky improved her best time in the 200 meters by 0.68 seconds, and in the 400 meters by 1.91 seconds. Let’s compare those improvements to what she needs for eight minutes: A per-lap improvement over 800 similar to what she has done in the 200 and 400 would put her within a few seconds of eight minutes.Does her preliminary time tell us anything? A time of 8:12.86 is a far cry from 8:00, and many of the best world records set in these games have been preceded by near-misses in the earlier rounds. But as a distance event, and as close to guaranteed of advancing as is possible, Ledecky’s time doesn’t tell us much. She was in a comparable situation in the 2015 World Championships in Kazan, Russia, when she put up 8:19.42 in her preliminary heat, a full 8.42 slower than her then-world record of 8:11. And here’s how that turned out: First, a note on how fast eight minutes would be: Since the ban on body-length and non-textile swimsuits in 2009, no woman other than Ledecky has managed to swim under four minutes in the 400-meter freestyle. So eight minutes would literally mean swimming 800 meters faster than anyone else can swim half the distance. But while that sounds crazy, it’s not out of character: Ledecky already swims the 1,500 meters at a faster pace than any other woman swims the 800 meters, and her present 800-meter time would already put her in the 10 fastest women in the 400 meters in the textile era.So can she do it? Perhaps even now?It would definitely take an incredible effort, great even among her great efforts. Using her splits from these Olympics and from her previous best times at each distance, I’ve constructed what this hypothetical 7:59.99 swim would look like, and it doesn’t look easy: She went on to break her record by 3.61 seconds (shattering what was then an 8:10 barrier in the process).A similar 12.08-second improvement on her leisure heat this year would be 5.9 seconds faster than her record, and would put her at 8:00.78. While a jump that large isn’t necessarily implied by the fact that she has done it before, it at least suggests that such an improvement — which would only be slightly larger than what her times and trends already suggest — is credible. And when you’re that close to such a milestone, who knows. A slightly faster reaction time here, a slightly longer sprint at the end there — plus it will be her last race of the games so she should hold nothing back — and the impossible looks a lot more plausible.

TravelWeek, online is reporting electricity is restored, water is restored and that work is on tirelessly to address the pending issues.The Tourism Minister, Ralph Higgs is quoted in the report saying that scheduled off season maintenance of resorts and hurricane repairs are on track for reopening in line with the coming high season. Among the resorts welcoming guests are: The Seven Stars, Atrium, Caribbean Paradise Inn, Grace Bay Suites, The Sands and the Somerset.There have been resort openings within the past week too, including Windsong, Shore Club, The Palms, Regent Grand, Grace Bay Club, West Bay Club, Villa Del Mar, the Venetian, the Tuscany and Reef Residences. Seven other resorts are due for openings this month, October: Amanyara, Coral Gardens, Ocean Club West, Blue Haven, Beach House and Gansevoort.The article which was published last week also features a report on the British Virgin Islands, a fellow UK overseas territory which also took a beating in historic Hurricane Irma. The BVI is however, unable to give the kind of report as is the Turks and Caicos – with assessments reportedly still ongoing on the island; damages were said to be over $290m for BVI. TCI Minister Higgs said the tourism product will continue to evolve to be more creative and innovative.A number of popular hang outs and shops were also highlighted in the article as open including IGA Gourmet, Regent Village, Fresh Catch, Mango Reef, Danny Buoys and Coco Bistro.Photo credit: Daily Hive
