5 things we learned from the Premier League

first_imgLiverpool’s lucky keeper calamitiesToby Alderweireld’s own goal lifted Liverpool after Hugo Lloris’s mistake © AFP / Paul ELLISShould Liverpool deliver a first league title in 29 years, Jurgen Klopp believes it will be “a championship of will”.His side showed their staying power once more to see off Tottenham in dramatic fashion, but also had no little luck, not for the first time this season, in an error by the visiting goalkeeper.Hugo Lloris parried the ball in off his own defender Toby Alderweireld to give Liverpool all three points to move back ahead of Manchester City in the title race on Sunday.Everton’s Jordan Pickford gifted Divock Origi a 96th minute winner in similar fashion in the Merseyside derby back in December, while Liverpool were fortunate that 39-year-old Julien Speroni’s only Premier League appearance of the season came at Anfield as he was at fault for at least two goals in a 4-3 win over Crystal Palace.Bernardo ‘the best’Manchester City could not have hoped for an easier start to a hectic final two months of the season as they remain on course for a quadruple of trophies.Pep Guardiola’s men cruised to a 2-0 win at Fulham with Bernardo Silva opening the scoring and then setting up Sergio Aguero to slot home his 29th goal of the season.Silva had to wait for his chance to shine at City, but has been outstanding this season and Guardiola admitted even among a star-studded squad, he is currently one of the first names on the his team-sheet.“Right now with the way he plays I cannot do anything else but put him on the pitch and let him play,” said Guardiola.“He’s so important for us. What he’s done for us is the best.”Sarri gets lucky breakMaurizio Sarri kept his cool as Chelsea hit back to beat Cardiff © AFP / Geoff CADDICKWith just six minutes left at Cardiff, Maurizio Sarri was on the brink of what would have been the worst result of his troubled reign as Chelsea boss.Trailing 1-0 to third bottom Cardiff after a shockingly limp display, Chelsea’s furious fans had subjected the Italian to chants of “We want Sarri out” throughout the second half.Having started with Eden Hazard, N’Golo Kante and in-form England winger Callum Hudson-Odoi on the bench, Sarri was in danger of paying for his bold gamble.But Sarri, who sent on Hazard in the second half, earned a stay of execution in dramatic fashion as Cesar Azpilicueta headed a controversial 84th minute equaliser from an offside position.Then in stoppage-time, Ruben Loftus-Cheek headed the winner from Willian’s cross to cap a much-needed act of escapology from Chelsea.The result kept Chelsea’s bid for a top-four finish intact and may have ensured Sarri avoids the axe, for a while longer at least.Huddersfield plan inquestJan Siewert wants to oversee a major inquest at relegated Huddersfield © AFP / Ian KINGTONHuddersfield manager Jan Siewert admits a detailed inquest is needed after a 2-0 defeat at Crystal Palace confirmed their record-equalling relegation.Siewert’s side join Derby, in 2008, as only the second Premier League team to lose their top-flight status before the end of March.With a miserable 14 points from their 32 games, Huddersfield have equalled the earliest relegation in the Premier League as Siewert failed to save them following his arrival as David Wagner’s replacement.Siewert conceded Huddersfield need root and branch reform at the end of their two-year stay in the Premier League.“I will not talk about bouncing back because at the moment it’s disappointment first of all,” he said.“We need to go through all the details, what happened, what were the reasons.”On-fire RashfordMarcus Rashford put Manchester United on course for victory against Watford © AFP / Paul ELLISMarcus Rashford netted in Manchester United’s 2-1 win over Watford to maintain his fine form since Ole Gunnar Solskjaer took over following Jose Mourinho’s sacking.The timing could not have been better for the 21-year-old, with a new contract worth a reported £150,000-per-week being discussed, as he took his tally to nine goals in the Solskjaer era.Rashford’s goals have seen him all but displace Romelu Lukaku as United’s number one choice as striker and source of goals.Solskjaer will be keen to secure Rashford’s signature on that mooted new deal as quickly as possible.0Shares0000(Visited 1 times, 1 visits today) 0Shares0000Bernardo Silva scored in Manchester City’s 2-0 win at Fulham © AFP / Adrian DENNISLONDON, United Kingdom, Mar 31 – Liverpool rode their luck to return to the top of the table, while Manchester City remain hot on their heels in a thrilling title race.Here are five things we learned from the Premier League this weekend:last_img read more

Four Arsenal signings to make up Gunners’ ‘New Invincibles’ team

first_img 2. Pedro (Barcelona) – Click right to find out who the final piece of the jigsaw might be… – Last summer Arsenal landed Alexis Sanchez in a brilliant transfer coup and they could return to the Nou Camp for another player this time out. The forward has seen his appearances severely restricted due to the attacking triumvirate of Lionel Messi, Neymar and Luis Suarez. A £24million move could be attractive for all parties involved. Chelsea manager Jose Mourinho has claimed Arsenal are just four top-class players away from having at team who could once again be invincible.“It’s even more difficult to dominate [the Premier League] than before,” said the Portuguese boss.“How can you speak about domination when everyone knows what will happen next summer? Give to Arsenal four top-class players and I think they will again be the Invincibles.”And considering the Gunners have only lost two of their last 18 Premier League matches, it’s actually not such a crazy claim from Mourinho.Back in 2003/04 the Gunners won the Premier League title while going the whole season without a single defeat with Arsene Wenger’s squad including the likes of Thierry Henry, Robert Pires, Patrick Vieira, Ashley Cole, Gilberto Silva, Sol Campbell and… Pascal Cygan.But which four players could conceivable turn the Gunners from also-rans into a second invincible side? talkSPORT takes a look.Click the right arrow to see the four top-class stars Arsenal should sign… 4 4. Signing Ilkay Gundogan from Borussia Dortmund could be the first step in turning Arsenal into the Invincibles again – Click the right arrow for another top-class star who could make Arsenal unbeatable again! – “Give to Arsenal four top-class players and I think they will again be the Invincibles,” said Jose Mourinho, but who could those signings be? German midfielder Gundogan is finally getting back to his best after injury problems curtailed his progress at the Westfalenstadion. His playmaking skills from deep could make him the perfect foil for the combative Francis Coquelin. 3. Iker Casillas (Real Madrid) – Click right to see which other La Liga star could join the Gunners… – In recent months David Ospina, a £3million summer signing from Nice, has usurped Wojciech Szczesny but the Colombian has an air of eccentricity about him that suggests a calamity could be just around the corner. But it appears the Gunners’ prayers could be answered with the news Spain star Casillas is keen on a move to the Emirates. Signing the 33-year-old would see them have a goalkeeper to rival Thibaut Courtois, Hugo Lloris and David De Gea. 4 4 4 1. Mats Hummels (Borussia Dortmund) – If Arsenal are to go another season undefeated the key will be their defence. When they went unbeaten they only conceded 26 goals, while this season they have let in 36 already, although this is still the third best in the Premier League. Per Mertesacker is on the wane as an elite centre-back and Gabriel is still adjusting to life in England, a move for World Cup winner Hummels would see Laurent Koscielny play alongside a truly brilliant defender.last_img read more

All About Rainscreens

first_img Start Free Trial Already a member? Log in Sign up for a free trial and get instant access to this article as well as GBA’s complete library of premium articles and construction details. This article is only available to GBA Prime Memberscenter_img UPDATED on June 24, 2018 with new product informationTwenty years ago, very few residential builders knew what a rainscreen was. These days, however, it’s no longer unusual to see siding being installed on vertical furring strips or a plastic drainage mat. As rainscreens become more common, mainstream builders are beginning to ask, “What’s a rainscreen? How do I know if I need one?”This article will pull together information to answer the most common questions about rainscreen gaps between siding and sheathing.You can’t really point to a rainscreen, because it isn’t a thing — it’s a system. That’s why I prefer to talk about a “rainscreen installation,” a “rainscreen approach,” or a “rainscreen gap.”For most residential builders, a rainscreen siding installation is one that includes an air gap between the siding and the water-resistive barrier (the asphalt felt or housewrap).Some purists insist that you can’t call it a rainscreen gap unless you have ventilation gaps at the top of the wall as well as the bottom of the wall. If it only has drainage gaps at the bottom, but no openings at the top, the purists insist that the system is more accurately called a “cavity wall.”However, the distinction between a cavity wall and a rainscreen wall isn’t particularly useful — in part because the distinction is based on a faulty understanding of “pressure equalization” principles — so I side with those who use the word “rainscreen” for either type of wall.Every well-designed rainscreen wall needs:Ventilation openings at the top of the wall are optional.Rainscreen gaps help walls manage moisture. A rainscreen gap helps to dry the sheathing, which may accumulate moisture during cold weather. It also helps to dry the siding when it is soaked by rain.These… last_img read more

Spray Foam Insulated Homes Need Ventilation

first_imgThe role and responsibilities of spray foam contractorsIf I were a spray polyurethane foam (SPF) insulation contractor, I’d do like they all do and make sure that every potential customer I talked to knew about SPF’s air sealing qualities. (I would not, however, try to sell people on fantasy R-values of 20 or 40 per inch, which I have known some SPF contractors to do.) RELATED ARTICLES Designing a Good Ventilation System GBA Encyclopedia: Ventilation ChoicesAre HRVs Cost-Effective?HRV or ERV?Ventilation Rates and Human HealthHow Much Fresh Air Does Your Home Need?Questions and Answers About Air BarriersSpray Foam Insulation Is Not a Magic Bullet Then I’d do what not nearly enough spray foam contractors do: I’d tell all my customers they need to install a mechanical ventilation system in every new home with spray foam. In fact, I’d include mechanical ventilation as one of the things I sell. (Maybe that’s just because I’d rather be an HVAC contractor, though.)If a client didn’t want me to do the ventilation, I’d have them sign a liability waiver acknowledging that they have been informed about the importance of mechanical ventilation in airtight homes. Then I’d have that piece of paper so I could pull it out if the homeowner ever came after me for poor indoor air quality.I’m not the only one saying that ventilation needs to be part of new homes with spray foam insulation. Recently, Mac Sheldon of Demilec emailed me about this issue and wrote, “I’m telling… preaching… admonishing… SPF contractors to never pull the trigger on a spray foam job until there’s a ventilation plan in place.”I believe that spray foam insulation can be an effective product to use in building enclosures. I also know that spray foam can be done poorly. No matter which way it’s done, however, mechanical ventilation is not optional in airtight homes. I wonder how many spray foam contractors will find that out the hard way. Most installations of spray foam insulation, when properly installed, act as an air barrier. When you use it instead of the fluffy stuff (fiberglass, cellulose, cotton), a house will be more airtight. That’s good.When a house is airtight, the nasties in the indoor air tend to stick around. Volatile organic compounds (VOCs), water vapor, odors, radon, and other stuff you don’t want to immerse yourself in make the home’s indoor air quality worse.How do you solve this problem? Mechanical ventilation. Well, source reduction and separation would come first, but airtight homes need mechanical ventilation.
