A One-Room Insulation Challenge

By on December 16, 2019

first_imgThe one-room addition on Emerson W’s home is not what anyone would realistically consider over-insulated: R-11 batts in the walls and R-19 at most in the ceiling. But the immediate issue is the floor. There’s no insulation at all there, and because the addition sits on concrete piers, there’s nothing to stop the wind from blowing freely below.“As you can see, outdoor air can simply pass through the open space under the floor,” Emerson writes in a post in the Q&A Forum. “When the flat EPDM roof needs to be replaced in 5 to 10 years, we will install exterior foam board outside the roof deck. Heating is primarily warmed air from rest of house or from the propane fireplace. Cooling is AC from rest of house.”Emerson is weighing a plan to excavate below the room to a depth of 2 feet before installing batt insulation between the joists, adding 1 or 2 inches of rigid polyisocyanurate insulation over the joists, and covering the assembly with OSB or plywood.“What approach would you take?” Emerson asks. That’s today’s Q&A Spotlight. Insulating Low-Slope Residential RoofsCrawl Spaces vs. SkirtsGBA Encyclopedia: Pier FoundationsBuilding an Unvented Crawl Space How to Insulate a Cold Floor Digging out is a good ideaGBA Editor Martin Holladay has some suggested reading for Emerson (see the “Related Articles” sidebar below), but in general suggests that digging out the soil from beneath the room is a good first step. RELATED ARTICLES Working in a tight space isn’t easyIt’s one thing to suggest insulation and air sealing below the floor, and another thing to drag tools and materials underneath the addition and actually do it.“I’ve done what you are contemplating and it’s a lot of work,” says Malcolm Taylor. “To get adequate space to fasten sheet goods to the bottom of joists you need about 2 feet. The work is done on your back. It’s very hard to get the good, tight joints needed to keep pests out, and the language used is generally unsuited for children.”He suggests Emerson think though each step carefully: add perimeter blocking for the insulation layer early as a guide, make some plywood jigs to hold one end of the sheet in place, and get the right tool. In this case, that’s a short, 12-volt impact driver for fasteners.Installing batts in the joist bays and then adding rigid foam is in itself pretty easy, he says, providing you install a perimeter of 2-by material. The plywood protecting the insulation can be nailed to this perimeter piece, and screwed to the joists through the foam.“Also it’s a lot easier if you have marked the joist locations on the perimeter 2-by,” Taylor adds. “I’d think about bedding the plywood in caulk at the edges, and caulking or taping the seams to keep carpenter ants and other pests out.”Codes in Taylor’s area forbids the use of untreated material close to grade. Just how long the plywood lasts will depend on how well the area beneath the room can be drained. “That may be your biggest challenge,” he says. “The work is just unpleasant. But then a lot of building tasks are.” “Excavating the soil under this addition is obviously a good idea,” Holladay writes. “So is adjusting the grade nearby, if possible. If you can afford to put in a real crawl space foundation (with concrete walls), all the better.”If Emerson keeps the pier foundation, opting not to spend the money on a full crawl space foundation, there are some sound strategies for insulating the floor. But a key consideration in all of this is how any excavation below the addition will affect drainage.“Once you have done digging the area out, you have a new problem: drainage,” Holladay says. “Unless the grade around the outside of the building is properly adjusted, the crawl space might become a mosquito-breeding pond. So you have to think this through. (That’s where the advantage of a traditional crawl space with concrete foundation walls starts to shine.)”Insulation in the floor could be either spray foam or a continuous layer of rigid foam below the joists (with fluffy insulation between the joists), he adds. Spray foam might do a better job with air-sealing the floor, but if the insulation contractor is conscientious, rigid foam insulation also could be just as successful, as long as it is carefully air sealed. Tackling the problem from the inside“What about installing rigid foam on the interior?”, Jon R asks.After a week of cold weather, with temperatures in the 20s, the idea has some appeal to Emerson. The addition has been the coldest room in the house — drafty, cold, and uncomfortable in the morning, he says — so “lifting the wood floor seems easier than digging a foundation.” Or, he adds, maybe he just needs a thick rug.Adding a layer of rigid foam over the existing floor is not a bad idea, Taylor tells Emerson, but there are some caveats. “Apart from the insulation, new subfloor, and flooring, you also have to deal with new trim, cutting down doors, and the transition in height between the old and new floors,” he says.Ceiling height is a concern. Emerson says that because of the low ceiling the room already has, he is considering of a “cut and cobble” approach: cutting pieces of insulation so they fit between the floor joists, with the possibility of adding a single layer above the joists to reduce thermal bridging.“Depending on the depth of the joist, this would get us to R-20 or so,” Emerson says. “Given the current room for improvement, I think we are seeking a ‘good enough’ solution, and bang for our buck. We can also reduce ceiling penetrations (eight recessed lights in a 12×12 room), and perhaps increase ceiling/attic insulation.” Consider roof insulation as wellThe roof has insulation issues of its own. Emerson describes the roof as flat and covered with an EPDM membrane. He’s met with the roofer who did the work and learned the roof is not vented.“His visit led me to discovering the ‘decorative soffits’ and also some fungus on the ceiling rafters under the EPDM roof. The fungus was white in color on the wood, with some black in color on the aluminum soffits. There are no leaks, and I am told the EPDM will be OK for 15 more years.”The fungus is visible on the rafter tails on the exterior of the addition. Emerson had a look by peeling back a section of the aluminum soffit on the roof’s 2-foot overhang. But the bottom line is the roof is not vented, and the situation is complicated by the manner in which the rafters over the addition are connected to the main house.“I had planned on blocking the joist bays where the low-sloped rafters intersect with the main house (i.e. extend into second floor joists — currently wide open on both sides),” Emerson explains. “This would block the colder air from entering the second-story joist bays.” That may have to do until the EPDM is replaced.Yes, Holladay replies, if rafters in the flat roof are continuous with floor joists in the main house, he absolutely needs airtight blocking between the rafters where the insulation ends. Our expert’s opinionGBA technical director Peter Yost added these thoughts:The first tough question is whether to move to a crawl space or stick with concrete piers? An important consideration, other than cost, is skill set. Sticking with piers is less expensive and simpler, involving only semi-skilled hard work. Replacing the foundation is going to involve mechanical excavation, temporary support, and casting the perimeter walls. In my book, that sounds expensive and complicated.The second tough question on this project is whether to work from underneath or from above. I know that working from underneath sounds more like a prison break than a retrofit, but the easiest and best way to get continuous insulation and good air sealing is from below.I am going to add two details to the pier floor assembly:First, include an air space between the subfloor and the cavity insulation. See Joe Lstiburek’s Building Insight on this topic. The space will not significantly change the energy efficiency of the assembly but it will improve thermal comfort for all those walking in that room in bare or stocking feet. I made this mistake on my own SIP kitchen addition, when I did not leave an air space in the pier floor assembly.Although the need for insulation and airtightness in the floor is no different than walls or ceiling, you don’t walk on the walls or the ceiling. When it gets cold and stays cold, the floor temperature of the addition is at least 5 F° cooler than the kitchen floor over the basement. When I tried to explain the science to my wife one cold morning, she said, “It never ceases to amaze me that you understand so much about buildings and so little about people.”The thermal images below help explain what I’m talking about.Second, protect the rigid insulation with galvanized metal lath or stainless-steel mesh. Coincidental to this work, I was just on the phone with Terry Brennan of Camroden Associates doing an interview for an upcoming feature article for BuildingGreen. (The likely title is “How Buildings Fail Their Users.”) He was relating how many times all sorts of buildings get infested with Norway rats, voles, squirrels, and the like. They love finding down-low weak spots to chew their way to warm and cozy nesting sites.And if you need to protect against termites or carpenter ants, maybe move from metal lath to stainless-steel mesh. I say maybe because Terry is not completely sure that the mammals will be thwarted by the mesh like the insects will. You might think that protecting the whole floor with sealed mesh or lath sounds extreme, but the only thing worse than carefully installing continuous rigid insulation and plywood would be having critters move in.last_img read more

TCI Hospital PSAs receive Special Customer Service Training from respected Community Figure

By on September 17, 2019

first_imgFacebook Twitter Google+LinkedInPinterestWhatsAppTurks and Caicos, May 22, 2017 – Providenciales – Patient Service Assistants at TCI Hospital are receiving special courses from a leading local trainer in the hospitality sector on the knowledge, skills, and competencies required to strengthen customer service and increase patient satisfaction.   The first session was held on Saturday, May 6th and additional sessions are underway. Popular hospitality sector figure, Blythe Clare was ideally selected due to her expansive track record in the fields of education and customer service training with public and private organizations.   Healthcare delivery, similar to tourism, is a service-centered industry and patients expect to be treated with compassion and sensitivity during their most vulnerable moments. Customer service in a medical setting has a unique set of challenges.    Some of these challenges were thrashed out during the course.    PSA’s are an essential component to patient satisfaction and these frontline employees are often the first point of engagement for persons in need of healthcare services, and bear the responsibility of shaping first impressions.  Patient satisfaction surveys continuously reveal that attitudes, manners and amenities encountered during patient experiences at medical facilities are equally important as treatment processes.    Therefore, health care management teams at TCI Hospital are reemphasizing that health care, from the patient’s perspective, are as much consumer focused as other service industries and should be delivered with the same regard.   Customer Service Training is also facilitated by the Education Department at TCI Hospital as part of mandatory training for all employees, year-round.  Commenting on the special courses facilitated by Ms. Blythe Clare, Chief of Medical Services, Dr. Denise Braithwaite-Tennant said: “Effective customer service optimizes the patient experience and reduces their anxiety about the unknown.   One of the simplest, least complicated, yet often overlooked aspects of delivering health care is practicing good customer service skills.   How we communicate with our patients from the first point of contact and even after they have left the hospital is an important part of the continuum of care.   Patient satisfaction survey results internationally support the importance of effective customer service in health care on patient engagement and satisfaction.  TCI Hospital – InterHealth Canada (TCI) Ltd is committed to a great patient experience and to this end, we have begun to strategically supplement our existing customer service training program with support from recognized local leaders in training.   It was during the TCI Care workshop where we were attendees, Ms. Blythe Clare offered us her training services and we were delighted for the opportunity for partnership.    We are thankful for Ms. Clare for her comprehensive, energetic, interactive and contextual training that was well received by our Patient Services team.”Press Release: interHealthCanada#psareceivecustomerservicetraining Related Items:#psareceivecustomerservicetraining Facebook Twitter Google+LinkedInPinterestWhatsApplast_img read more

Gonzalo Higuain finally scores a brace for Chelsea FC

By on

first_imgFind out how striker Gonzalo Higuain finally scored his first two Premier League goals for Chelsea against Huddersfield Town at Stamford Bridge.After not having the most ideal debut for Chelsea FC this past week at Bournemouth, Argentine striker Gonzalo Higuain finally had his chance to prove why Maurizio Sarri brought him from Italian football.‘Pipita’ needed a more relaxed environment in order to get that confidence he required in order to start scoring goals for his new club, this version of the Blues was nothing like the one we saw at Vitality Stadium but they were playing against bottomers Huddersfield Town.This match would be very easy for Gonzalo Higuain to finally get his dream debut at Stamford Bridge, Sarri also decided to place Eden Hazard back on his left-winger position and the modification also paid off in the final result.The first half started with the Blues going all in for the first goal, it took the Blues over fifteen to find the right opportunity for Gonzalo Higuain’s killer instinct.The Argentine had already tried to land a few shots on target with no luck, but Kante was able to find him to get that first goal on the 16th minute of the match with a potent right-footed shot with practically no angle to take [email protected]_Higuain 🙌 🙌 #CHEHUD pic.twitter.com/SwtktcAOEl— Chelsea FC (@ChelseaFC) February 2, 2019Eden Hazard scored the second goal just before half-time after the Blues got awarded a penalty, the Belgian winger was very active throughout the whole first half and manager Maurizio Sarri seemed satisfied with the overall performance thus far.Ross Barkley’s inclusion in the starting eleven was also a great idea from the manager, the English player was a perfect link between N’Golo Kante’s defensive tasks and Gonzalo Higuain’s danger area.This also gave Hazard more freedom to play on his preferred left flank without having to move to the middle because Ross had that space covered very well, the Belgian actually received a clinical assist from Barkley well into the second half and Eden moved past the goalkeeper with a beautiful dribble that gave him the space to score that third Chelsea goal.With the Blues’ number ’10’ already having a brace, Gonzalo Higuain was eager to get another goal that could give him even more confidence in a game that was already decided for Maurizio Sarri’s squad.This moment came only a few minutes after Hazard’s second goal, and it was something we weren’t ready for.Tammy Abraham, ChelseaChelsea hat-trick hero Tammy Abraham hopes for more Andrew Smyth – September 14, 2019 Tammy Abraham hopes this season will be his big breakthrough at Chelsea after firing his first hat-trick for the club in Saturday’s 5-2 win at Wolves.⚽️⚽️ Double trouble! ⚽️⚽️ pic.twitter.com/4LJpIbtvjV— Chelsea FC (@ChelseaFC) February 2, 2019Turns out that Gonzalo Higuain found a perfect partner in N’Golo Kante, the French midfielder provided him with a second assist just outside the box that ‘Pipita’ turned into pure magic.A long-range curler straight to the top corner left Higuain’s right foot, a perfect way for him to get his dream debut as a Chelsea player at Stamford Bridge.Manager Maurizio Sarri has a very special understanding of this player, they proved it during the Napoli days and it appears they might do it again at Chelsea this season.The final minutes were also good enough for one last goal for the Blues, Willian was slick enough to see David Luiz moving closer to him during a corner-kick and assisted his compatriot in order to get that final goal through a well-placed header.With this 5-0 result, Chelsea can finally breathe a little bit and salvage their Top Four position regardless of how Arsenal does on Sunday vs Manchester City.The heated discussion Maurizio Sarri had with the players after the Bournemouth defeat seems to have paid off, but the Blues still have to play against a more competitive squad and see if they really are back to form.🌟🌟🌟🌟🌟#CHEHUD— Chelsea FC (@ChelseaFC) February 2, 2019How many goals will Gonzalo Higuain score for Chelsea this season?
