Insulation for the atticAttics are one of the neglected spaces in the our homes — an afterthought, really. Many trusses are designed the same way they were years ago. There is no thought put into the lack of insulation above the top plate on exterior walls. Heeled trusses [also called raised-heel trusses or energy-heel trusses] were developed as a solution to this problem. Adding a small heel enables deeper insulation over the top plate of exterior walls and helps prevent thermal short-circuiting to and from the attic space.It seems that raised-heel trusses may become a mainstay for the future since code changes now require attics to be insulated to a minimum of R-50. Large heels mean more blocking and higher baffles to combat the effects of wind-washing on the thermal effectiveness of the attic insulation. The key here is to direct any wind (entering the attic through the soffit) far above the layer of insulation. The air contained in the insulation remains stagnant which maintains its thermal effectiveness.Adding insulation to an attic is pretty cost-effective — even for a Passive House. There are several blown-in insulation choices available in our local market. Namely, cellulose and fiberglass. At about R-3.26 per inch, cellulose seemed to give the best value for my dollars. The manufacturer (Thermocell) was able to provide an R-value based on the depth of insulation required. The fiberglass provider wasn’t able to specify above R-60 so it was going to be a matter of blowing in extra and crossing our fingers. Even if they extrapolated the depth required, the initial thickness was going to be higher than cellulose in order to account for settling.The cost of fiberglass is slightly higher than cellulose and would require higher baffles which would further increase the total cost of the installation. There are many more reasons for choosing cellulose (which I will explore in a future post), but the main point here is that I need lots! Combining Exterior Rigid Foam With Fluffy Insulation Calculating the Minimum Thickness of Rigid Foam SheathingQuestions and Answers About Air BarriersOne Air Barrier or Two? Before making a final choice about which products to use, I decided to further investigate the documented effects of compressing fiberglass insulation. I have heard people say you shouldn’t compress fiberglass insulation. However, this depends heavily on installation details.So, can you compress a deep fiberglass batt into a shallow stud wall cavity? You sure can, and even though compressing the batt lowers its nominal R-value, you still end up with a higher R-value than a standard batt would provide. The formulas are pretty simple.Final R-Value = Original R-Value + Change in R-Valuewhere,Change in R-Value = 1/2 x (Percentage change in thickness) x (Original R-Value)where the “Percentage change in thickness” is100% x ( Compressed Thickness – Original Thickness) / (Original Thickness)So for R-31 (9 1/2 inch thick) batt compressed into a 7 1/4 inch stud space, the percentage change in thickness is100% x (7.5″-9.5″) / 9.5″ = -21%.This translates into a change in R-Value equal to1/2 x (-21%) x 31 = -3.3.So the final R-value would be 27.7 in the cavity. This seemed like a good option. But there were some details to keep in mind and a few things to work around.First, R-31 batts only come in a 24-inch wide width while the stud cavities are actually 22 1/2 inches wide because of the 24-inch on-center spacing of the studs. So every R-31 batt would have to be cut to the proper width. RESNET recommends insulation 1 inch bigger than the cavity (from what I recall). This is interesting because most manufacturers provide insulation at widths that are only 1/2 inch wider than the stud cavity.I omitted blocking from the walls in order to provide a full stud space for insulation. This led to a minor problem: As the studs started to dry, they also started to warp. The cavities were 22 1/2 inches at the plates but up to 23 inches wide elsewhere in the cavity. Cutting insulation at non-uniform widths would be extremely time consuming.My work-around was to use the whole batt in the cavity without cutting it to width. At 1 1/2 inches larger than the cavity in places, the batt would only be wider than the RESNET specification by 1/2 inch. The effect of this is compression along the width of the cavity. Since the R-Value changes linearly with compression, I would expect the same formula above applies to the width of the cavity also. So, using the above formula and my calculated R-value under compression (i.e. R-27.7) the insulation would have a variability from R-27.1 to R-26.8, assuming a perfect installation. My plans called for fiberglass batt insulation in the stud cavities with an OSB air barrier to the inside of the wall and EPS foam sheathing on the outside of the house. The problem is that the walls are framed with 2x8s, and my check of local suppliers found there are very few fiberglass options for a 2×8 wall (7 1/4 inches deep).Several companies make batt insulation in thicknesses of 8 1/2 inches (R-28) and 7 1/2 inches (R-22). Another option was to gang up batts of different thicknesses and R-values but this seemed complicated and installation could take twice as long. In either case, the insulation will have to be compressed into the wall cavity with the OSB. Yet another option was blown in fiberglass. At about R-29.8 it is the best option for conformity inside the wall cavity and provides the highest R-value. This would be my best option if budget allowed for it. Fears of bulging walls were unfoundedSeveral people suggested that this much compression would lead to issues with installation of the interior OSB air barrier — bulges in the OSB between the studs. We mocked up a batt installation and covered it with a sheet of OSB. We did need two people to install the mock up: one person to hold and compress the insulation with the sheet of OSB, and the other person to nail the OSB in place.The trick was to start nailing at the bottom plate (a pneumatic nailer worked best). We then pushed the sheet in (compressing the insulation behind it) about 16 inches up the wall and nailed it again. We kept doing this until the full sheet was nailed. After installation was complete we ran a straightedge horizontally across the OSB and found no bulging from the insulation. The bending stress on the OSB across a 2-foot span appears nonexistent. Compressing fiberglass with OSB works fine. However I can guarantee that anything more than R-31 is very hard to compress. Don’t bother trying it!Installation of the batts was tricky at first. Simply pushing them into the cavity led to uneven filling. Repeatedly, the batts did not fill the corners of the wall cavity at the exterior side. To correct this we had to start by angling the batt into the corner while compressing it in width to fit into the opposite side. We would use our hands to pull the insulation away slightly and visually inspect the corners and tucked the insulation into the corners as needed. (See Image #2 below.)The trick to making it puffy is to make sure the batt is tight-fitting but only about 1/2 inch bigger than the stud cavity in both height and width. The batt then slips in the cavity with ease and the center still bulges outside the stud cavity which will make for more uniform compression once the OSB is installed.Having several people to install insulation makes the job move along quickly. However, it also introduces some variations in results. We inspected each other’s installations and watched one another’s installation method to narrow down the best way to achieve a good installation and came up with a set of rules. Our reasoning was that approach would yield a more consistent result.

BLOGS BY DAVID GOODYEAR Installing Windows and DoorsFoam Sheathing and Window DetailsFraming and Air SealingA Well Insulated SlabFootings and Frost WallsA Final Design and Energy ModelingAn Introduction to the Flatrock Passive House RELATED ARTICLES Next, the air barrierAfter completing the insulation, we started installing the first component of our airtight barrier, the OSB. We just followed the procedure we had mapped out with our mock-up. Since we wanted to keep joints to a minimum, we worked with full sheets.Around windows, we typically placed the sheet vertically in front of the buck then scribed a line around the buck opening onto the OSB and cut the opening out with a circular saw. If the sheet covered the window, we ripped the sheet to the width of the nearest stud centered under the window opening so we could reach inside the buck opening to scribe the window opening. With this methodology we will be sealing two fewer joints per window when compared to installing individual pieces above and below the window bucks. In some cases this may not work, but I figured that more solid OSB would result in fewer air leaks. It also saved on expensive tape as well as time for caulking and taping.Some penetrations through the air barrier were easier to implement up front rather than waiting till later. The ERV vent termination was one of those penetrations. The termination fitting was the DVS-100 from Reversomatic. It is a dual vent that can be fitted into the wall in a single piece. The termination fitting was fitted into the wall cavity from the exterior. Extension pipes were added to the termination and spray foam was installed around the unit. The spray foam was trimmed so fiberglass would fit nicely around the pipes.We marked out where the penetrations would be on a sheet of OSB and drilled the holes necessary for the vent pipe penetrations. (See Images #3 and #4, below.) In order to get nice tight insulation around the vent pipes, I had to figure out how to drill holes through fiberglass. Using a template placed on the batt at the right location, I stepped onto the templates with all of my weight. A drill with a hole saw could then be used to drill the hole locations to give nice round holes for fitting around the vents. (See image #5 below.) Building an attic hatchAir sealing an attic hatch is not an easy task. Fortunately, my designer provided great details for the attic opening. It’s basically an OSB box with a sloped end. (See Image #6 below.) The OSB box was framed between the attic trusses in the middle of the future hallway. (Framing the interior is yet to start.) The box is about 32 inches high. At this height, it is about 6 inches above the top of the insulation.The attic hatch door will be insulated with EPS. Luckily enough, I have lots of 4-inch scraps left over from my foundation. I will probably make it 12 inches thick since I can then just stack three layers of 4 inches each. This being said, I had to plan ahead for how the person entering the attic will deal with placement of the attic door. What I came up with is a landing at the top of the attic hatch opening where the attic door can be placed after it’s popped off the hatchway.With 26-inch-deep insulation, it’s not going to be an easy task for the insulator to walk around in the attic, so I had to think ahead about how to make his life easier when blowing the insulation. A catwalk supported by the trusses was easy to make with some 2x4s. (See image #7 below.)The catwalk runs about 32 feet along the length of the attic at a height of 32 inches above the attic deck below. It will be much safer than trying to navigate the attic while treading on truss webbing and pulling a large hose around. With the catwalk situated approximately in the center of the attic space, the insulator should be able to reach either side of the house. It will also make future inspections much easier than wading around in 26 inches of insulation!
Together, LeBron and Kyrie combined for a Game Score of 72.4, the top single-game performance by a duo in the finals since 1984.

Tennis fans were disappointed this weekend when Serena Williams backed out of the Italian Open before her semifinal match. Clay has perennially been her worst surface. Williams said backing out was the best way to prevent any further injuries—just before the summer stretch of the French Open, Wimbledone and the U.S. Open—after she had been complaining about pains in her lower back.“I [felt] a little bit of ache and pain and don’t want to go out there and start compensating and eventually hurt something else,” Serena told reporters.Serena’s withdrawal means that Li Na, the reigning French Open champion, will automatically advance to the finals in Rome.According to Williams this isn’t the first time her back has been a problem since she began playing in the Italian Open. Earlier this week she was reported saying, “It was feeling a little stiff and I don’t think this is the right moment to force [it]. I just want to relax and get ready for the next few months.” The decision has put an end to Serena’s streak of 17 consecutive victories. According to ESPN, several other players are nursing injuries as well, but there is no word out yet on whether there will be more withdrawals from the Italian Open.“Everyone. I’m sooooo sad and sorry I had to pull out of what has become my favorite tournament in Rome,” Serena tweeted. “Everyone has become so nice here in Rome and the tournament director is amazing. I will be here next year for sure.”Li Na will go on to compete with Maria Sharapova, the defending champion of the Rome Final, or Angelique Kerber of Germany.
#MagneticMediaNews Facebook Twitter Google+LinkedInPinterestWhatsAppProvidenciales, TCI, December 28, 2016 – Former PNP Leader, former Chief Minister and PNP Opposition Leader in the House of Assembly, Hon Charles Washington Misick has issued statement on the holiday season, reminding that it is a time and opportunity of great reflection and introspection. The all island elected member said, and I quote… “ Reflect on the events of the last twelve months and how it has shaped the lives of us all. In that regard we have much to be thankful for as our beloved Turks and Caicos continues to prosper, and be peaceful albeit new concerns about increased crime. Introspective as we look-back over our own behaviour and actions to discover consistencies and contradictions regarding our calling to ‘Love mercy and do justly’ and to walk in humility before our God.” Hon Misick expounds by saying that , “as we face a new year, we will continue to experience triumphs and despair at the personal and national level, and that in it, we must resolve to summon the courage to face these, girded in the faith of our fathers pledging our commitment first to God and our loyalty to country above self and all others.” You can read the full message at MagneticMediaTV.com.

The Defense Department has obligated $55.7 million for civilian water and wastewater improvement projects related to the realignment of Marines from Okinawa to Guam, Del. Madeleine Bordallo (D) said this week.The funds were authorized in the fiscal 2016 defense authorization bill and are part of a $106.4 million appropriation for public infrastructure projects approved by Congress. Language Bordallo added to this year’s defense policy bill would authorize the remaining funds.About 5,000 Marines and 1,300 dependents will be moving from Okinawa to Guam.The funding released this week will cover four projects, reported Pacific Daily News:final planning, design and construction to refurbish the sewer line in Northern Guam which supports Andersen Air Force Base and the new Marine Corps Base ($30.6 million);improvements to the northern district wastewater treatment plant ($21 million);final planning, design, and construction to improve the monitoring system for Guam’s northern aquifer ($3.7 million); andanalyses for the water and wastewater projects by the U.S. Environmental Protection Agency ($350,000).The new Marine base is expected to produce about 1.2 million gallons of wastewater per day.“These projects are critical to supporting upgrades and improvements to Guam’s civilian water and wastewater system, and they further demonstrate the progress we are making to move forward with the Marine realignment,” Bordallo said. “I will continue to build on the progress that we have made to ensure that the realignment moves forward and is mutually beneficial to our civilian and defense community.” Dan Cohen AUTHOR
