IMPENDULO: Lokhu okuchazayo yidamu leqhwa ngeshwa elivame kakhulu ezindlini ezindaweni ezinobusika obubandayo kanye neqhwa. Amadamu eqhwa akheka lapho iqhwa lincibilika bese liphinde libe yiqhwa (okwaziwa ngokuthi umjikelezo wokuncibilika kweqhwa), futhi uphahla olufudumele ngokungavamile luyimbangela. Lokhu akugcini nje ngokuphumela ekulimaleni kophahla noma ohlelweni lukathayela, kodwa “[amadamu eqhwa] abangela izigidi zamaRandi emonakalweni wezikhukhula minyaka yonke,” kusho uSteve Cool, umnikazi kanye no-CEO we-Ice Dam Company kanye neRadiant Solutions Company. . Ama-ice jam avame kakhulu ophahleni lwama-shingle, kodwa angakheka nakwezinye izinto zokufulela, ikakhulukazi uma uphahla luyisicaba.
Ngenhlanhla, kunezixazululo eziningi ezihlala njalo nezesikhashana ezinkingeni zophahla oluyiqhwa. Ukugcwala kweqhwa ngokuvamile akukona okwenzeka kanye, ngakho abanikazi bezindlu nabo kudingeka bacabangele ukuthatha izinyathelo zokuvimbela ukugcwala kweqhwa esikhathini esizayo. Qhubeka ufunde ukuze uthole ukuthi kungani amadamu eqhwa akheka nokuthi wenzeni ngawo.
Isithwathwa amanzi eqhwa anqwabelana emaphethelweni ophahla ngemva kokuwa kweqhwa. Lapho umoya osegumbini elingaphansi ufudumele, ukushisa kungadluliswa ophahleni futhi ungqimba lweqhwa luqala ukuncibilika, okubangela ukuba amaconsi amanzi aconse ophahleni. Lapho la maconsi efika onqenqemeni lophahla, aphinde aba yiqhwa ngenxa yokuthi i-overhang (ukhoni) ngaphezu kophahla alukwazi ukuthola umoya ofudumele ovela ophahleni.
Njengoba iqhwa liyancibilika, liwa futhi liphinde libe yiqhwa, iqhwa liyaqhubeka linqwabelana, lakha amadamu angempela - izithiyo ezivimbela amanzi ukuba aphume ophahleni. Amadamu eqhwa kanye nama-icicles angenakugwemeka okuba umphumela angenza indlu ibukeke njengendlu yesinkwa se-ginger, kodwa qaphela: ayingozi. Ukwehluleka ukuhlanza ama-icicles kungenye yamaphutha amakhulu abanikazi bezindlu abawenza njalo ebusika.
Amadamu eqhwa anganganakwa kalula - phela, ngeke yini inkinga izixazulule lapho lifudumala futhi neqhwa liqala ukuncibilika? Kodwa-ke, uma engalawulwa kahle, amadamu eqhwa angabeka engcupheni enkulu ezindlini nakubahlali bawo.
Nazi ezinye zezindlela ezingcono kakhulu zokususa isithwathwa. Kodwa khumbula lokhu ngobusika obuzayo: isihluthulelo sokuvikela isikhathi eside ukuvimbela amadamu eqhwa ukuthi akheke.
Uma amadamu eqhwa seakhiwe, kufanele asuswe ngaphambi kokuba ukuncibilika okwengeziwe nokubanda kungabangela amadamu eqhwa ukuba ande futhi aveze uphahla namathafa engozini eyengeziwe. Izindlela ezivame kakhulu zokususa idamu leqhwa zihilela ukwelapha iqhwa ngomunye wabakhi beqhwa abangcono kakhulu noma ukusebenzisa elinye lamathuluzi edamu leqhwa angcono kakhulu ukuhlephula iqhwa libe yizicucu ezincane ukuze lisuswe. Uma ungabaza, kuvamise ukutuseka ukufuna usizo kusevisi yokususa iqhwa.
I-calcium chloride, efana ne-Morton's Safe-T-Power, iyizinto ezifanayo ezisetshenziselwa ukuncibilikisa nokususa imigwaqo yeqhwa kanye nemigwaqo yaseceleni, kodwa ayikwazi nje ukufafazwa emadamini eqhwa. Esikhundleni salokho, faka amabhola emlenzeni wesokisi noma we-pantyhose, bese ubopha isiphetho ngentambo.
Isikhwama esingamaphawundi angu-50 se-calcium chloride sibiza cishe u-$30 futhi sigcwalisa amasokisi angu-13 kuya kwangu-15. Ngakho-ke, esebenzisa i-calcium chloride, umninikhaya angakwazi ukubeka isokisi ngalinye libheke phezulu phezu kwe-weir, nokuphela kwesokisi kulenga intshi noma amabili phezu konqenqema lophahla. Ngokuncibilikisa iqhwa, kuzodala umgudu oshubhu edamini leqhwa ozovumela amanzi ancibilikayo engeziwe ukuthi aphume ngokuphepha ophahleni. Kuyaqapheleka ukuthi uma iqhwa elengeziwe noma imvula ina ezinsukwini ezizayo, isiteshi sizogcwala ngokushesha.
ISEXWAYISO: Ungafaki i-calcium chloride ufake usawoti we-rock lapho uzama ukuncibilikisa iqhwa, njengoba usawoti wedwala ophahleni ungalimaza ama-shingles futhi ukugeleza kungabulala izihlahlana namahlamvu ngaphansi. Abanikazi bezindlu kufanele baqinisekise ukuthi imikhiqizo yokuncibilika kweqhwa abayithengayo iqukethe i-calcium chloride kuphela, ephephile kuma-shingles nasezitshalweni.
Ukugqekeza idamu leqhwa kungaba yingozi futhi kuvame ukwenziwa kangcono nguchwepheshe. "Cishe akunakwenzeka ukuphula amadamu eqhwa ngesando, ikakhulukazi ngokuphepha," kusho uKuhl. Ingxenye ye-intshi ngaphezu kwendiza yophahla ukuze ingalimazi,” uyeluleka.
Ukuphula idamu leqhwa kuvame ukuhlanganiswa nokuncibilikisa iqhwa ngandlela thize, njengokusebenzisa isokisi le-calcium chloride njengoba kuchazwe ngenhla, noma umusi ophahleni (bheka ngezansi). Okokuqala, umninikhaya ohlakaniphile noma isandla esiqashiwe udinga ukususa iqhwa eliningi ophahleni futhi agxobe amagatha edamini. Khona-ke, lapho iqhwa liqala ukuncibilika, amachopho esiteshi angase athentwe kahle ngesando, njengesando se-fiberglass ye-Tekton engu-16-ounce, ukuze kunwetshwe isiteshi futhi kuthuthukiswe ukugeleza kwamanzi. Ungalokothi ugawule iqhwa ngembazo noma ngehatchet, kungalimaza uphahla. Ukuphuka kwamadamu eqhwa kungabangela izingcezu ezinkulu zeqhwa ukuthi ziwe ophahleni lwendlu, kuphahlazeke amafasitela, kulimaze izihlahla, futhi kulimaze wonke umuntu ongezansi, ngakho-ke kufanele kuqashelwe kakhulu. Izinqamuli zamadamu eqhwa kufanele zenze kanjalo zisendaweni ephakeme ophahleni, hhayi ukusuka phansi, okungase kubangele ukuwa kweqhwa elisindayo.
Amadamu okukhipha uqweqwe ngesitimu kuwumsebenzi ongcono kakhulu ukushiyelwa enye yezinkampani ezingcono kakhulu zokufulela njengoba kudingeka imishini yokuhweba isitimu ukuze kushiswe amanzi futhi kusakazwe ngaphansi kwengcindezi. Umuntu oqashiwe uphahla kuqala asuse futhi asuse iqhwa eliningi ophahleni, bese ethumela isitimu edamini leqhwa ukuze lisize ukulincibilikisa. Abasebenzi bangakwazi futhi ukuhlinza ingxenye yedamu kuze kube uphahla lusuke luphele iqhwa. Ukukhipha uqweqwe ngobuchwepheshe kungase kubize kakhulu; U-Cool uthi “amanani emakethe ezweni lonke asukela ku-$400 kuya ku-$700 ngehora.”
Isimo sezulu esibandayo singadala umonakalo ezindlini, kwesinye isikhathi sibe sibi kakhulu. Ezinye izindlela zokuvikela iqhwa ophahleni zidinga ukuthi iqhwa likhishwe ophahleni, kanti ezinye zidinga ukuthi uphahla lwendlu lupholiswe ukuze kuvinjelwe ukudluliswa kokushisa kusuka ophahleni kuya ophahleni. Okokuqala, gwema isithwathwa ngokuzama indlela eyodwa noma ngaphezulu yokuvikela isithwathwa ngezansi.
Nakuba abanikazi bezindlu ngesinye isikhathi belulekwa ukuthi bageqe amamitha ambalwa ophahleni kuphela, lokhu “kungabangela izinkinga ezinkulu eziholela kulokho okwaziwa ngokuthi idamu eliphindwe kabili – idamu leqhwa lesibili lapho usika khona endaweni ephakeme yophahla ukuze wakhe idamu lesibili. i-ice dam.” Iqhwa futhi yehlise,” kusho uKuhl. Kunalokho, utusa ukususa iqhwa eliningi ophahleni njengoba kuphephile. Ngenxa yezimo ezingase zishelele, ukubheja kwakho okungcono kakhulu ukuqasha enye yezinsiza ezingcono kakhulu zokususa iqhwa noma ufune “ukususwa kweqhwa eduze kwami” ukuze uthole inkampani ezonakekela le ngxenye.
Kubanikazi bezindlu abathatha umzila we-DIY, kungcono ukusebenzisa i-rake yophahla engasindi njenge-Snow Joe Roof Rake efika nesandiso esingamamitha angu-21. Ngokushesha ngemva kokuba iqhwa liwile, ngenkathi lisathambile, kubaluleke kakhulu ukususa iqhwa elivela ophahleni nge-rake. Lokhu kuzosiza ukunciphisa uqweqwe. Amaraki amahle kakhulu azohlala iminyaka futhi enze ukususa iqhwa ophahleni kube umsebenzi olula njengoba asikho isidingo sokukhuphuka izitebhisi. Njengendlela yokugcina, abanikazi bezindlu bangazama ihhashi leqhwa elenziwe ekhaya ekhaya labo.
Lapho izinga lokushisa ekamelweni elingaphansi komhlaba lingaphezu kwezinga-qhwa, lingabangela ukuba iqhwa elisophahleni lincibilike bese liphinde libe yiqhwa ngaphansi kophahla. Ngakho-ke noma yini ephakamisa izinga lokushisa kwe-attic yakho ingaba yimbangela engase ibe imbangela yokwakheka kweqhwa. Le mithombo ingase ihlanganise ukukhanya okwakhelwe ngaphakathi, izintuba zokukhipha umoya, amapayipi omoya, noma amapayipi e-HVAC. Ukuxhuma kabusha noma ukufaka esikhundleni sezingxenye ezithile, noma ukuzisonga nge-insulation kungasiza ukuxazulula le nkinga.
Umqondo uwukumisa ukudluliswa kokushisa ngophahla ngokuqala umjikelezo wokuqandisa. Okunye okungu-8-10 amayintshi okufakwa kwe-attic kuzosiza ukuvimbela ukudluliswa kokushisa futhi kusize ukugcina ikhaya lifudumele, ngakho abanikazi bezindlu bachitha imali encane ekugcineni ikhaya labo lifudumele phakathi nobusika. Ukufakwa kwe-attic okungcono, okufana nokufakwa kwe-Owens Corning R-30, kuzovimbela ukushisa kusuka endaweni yokuhlala kuya ku-attic futhi ngaleyo ndlela kunciphise ingozi yamadamu eqhwa.
Kungakhathaliseki ukuthi ungeza kangakanani i-insulation ku-attic yakho, lisazoshisa kakhulu uma umoya ofudumele ovela endaweni ohlala kuyo uphoqelelwa ngokusebenzisa imifantu nezikhala. “Izinkinga eziningi zihlobene nokungena komoya oshisayo lapho okungafanele ungene khona. Ukulungisa lokho kuvuza komoya kuyinto yokuqala ongayenza ukunciphisa amathuba okwakheka kweqhwa,” kusho uKuhl. Izinketho Zokunwetshwa Kwegwebu Vala zonke izikhala ezizungeze imisele yendle futhi uqondise kabusha indawo yokugezela kanye nezindawo zokomisa ukusuka ephahleni ukuya ezindongeni zangaphandle zekhaya. Igwebu eliphezulu lezinga eliphezulu le-insulating elifana ne-Great Stuff Gaps & Cracks lingamisa umoya oshisayo ovela ezindaweni zokuhlala ukuthi ungangeni ku-attic.
Ama-roof vents angcono kakhulu kufanele afakwe kwi-soffit eduze kwe-underside ye-eves, ephuma phezulu ophahleni. Umoya opholile uzongena ngokwemvelo kuma-soffit vent njenge-HG Power Soffit Vent. Njengoba umoya obandayo ongaphakathi ophahleni ushisa, uyakhuphuka futhi uphume ngentuba yokukhipha umoya, njenge-Master Flow Solar Roof Vent, okufanele ibe phezulu ophahleni. Lokhu kudala ukugeleza komoya ohlanzekile njalo ku-attic, okusiza ukuvimbela ukushisa okweqile kwedekhi yophahla.
Ngenxa yokuthi uphahla lufika ngawo wonke amasayizi kanye nokucushwa, ukuklama uhlelo lokungenisa umoya ophahleni kuwumsebenzi womuntu onekhono.
Intambo yokushisa, eyaziwa nangokuthi i-heater tape, iwumkhiqizo ophikisana ne-icing ofakwe engxenyeni esengozini kakhulu yophahla. "Amakhebuli afika ngezinhlobo ezimbili: amanzi ahlala njalo futhi azilawula," kusho uKuhl. Amakhebuli kagesi e-DC ahlala evuliwe ngaso sonke isikhathi, futhi izintambo ezizilawulayo zisebenza kuphela lapho izinga lokushisa liku-40 degrees Fahrenheit noma libanda. U-Kuhl uncoma ukuthi kusetshenziswe izintambo ezizilawulayo njengoba zihlala isikhathi eside, kuyilapho izintambo ezidonsa amanzi ezingashintshi zingasha kalula. Izintambo ezizilawulayo nazo zisebenzisa amandla amancane futhi azidingi ukusebenza ngezandla, ngakho-ke azincikile kubahlali basekhaya ukuthi bazivule ngesikhathi sokuduma kwezulu.
Abanikazi bezindlu bangathola uphahla oluhlala amanzi njalo kanye nezintambo zokususa uqweqwe lukathayela (ikhithi yekhebula lophahla lwe-Frost King iyona ndlela engcono kakhulu) ezitolo eziningi zokuthuthukisa ikhaya ngo-$125 kuya ku-$250. Zigxiliswe ngqo phezulu kwama-shingles anezinsimbi kuma-eaves ophahleni. Lezi zintambo zingafika kahle ngokuncinza futhi zivimbele amadamu eqhwa ukuthi angakheki, kodwa ayabonakala futhi ukuklebhula uphahla kungabangela ukuba amadamu eqhwa agudluke uma umninikhaya engaqaphile. Izintambo zokushisisa ezizilawulayo ngokuvamile zidinga ukufakwa kochwepheshe, kodwa uma sezifakiwe zingahlala iminyaka eyi-10. “Enye yezinzuzo zamakhebuli okushisa phezu kwezindlela zokwakha njengokudlula, ukufaka ugesi, kanye nokukhipha umoya ukuthi…ungaqondisa izindawo eziyinkinga ukuze uzivikele. izindlela,” kwengeza uKuhl.
Amasistimu ochwepheshe afana ne-Warmzone's RoofHeat Anti-Frost System afakwa ngaphansi kwama-tiles ophahleni futhi kufanele afakwe inkampani eqeqeshiwe yokufulela ngesikhathi esifanayo lapho kufakwa amathayela amasha ophahla. Lezi zinhlelo ngeke zibeke engcupheni ukubukeka kwe-roofline futhi zenzelwe ukuhlala iminyaka. Ngokuya ngosayizi wophahla, uhlelo lokususa uqweqwe olufakwe ngobungcweti lungangeza u-$2,000 kuya ku-$4,000 ezindlekweni eziphelele zophahla.
Abantu abaningi bezwile ukuthi ama-gutter avaliwe adala ukugcwala kweqhwa, kodwa u-Cool wachaza ukuthi akunjalo. “Ama-gutters awadali isiminyaminya seqhwa. Kunezinkinga eziningi ezingase ziphakame lapho indle igcwala iqhwa, kodwa [ukuvinjwa kweqhwa akuyona enye yazo]. Lena inganekwane ejwayeleke kakhulu,” kusho uKuhl. , ukuvinjelwa kwama-drain Umsele wandisa indawo yokwakheka kweqhwa futhi uholela ekuqoqweni kweqhwa elengeziwe. Amagatha agcwele amaqabunga awile kanye nemfucumfucu ngeke avumele amanzi ukuba aphume embhobheni njengoba kuhlosiwe. Ukuhlanza ama-gutter ngaphambi kobusika kungavimbela ukulimala kophahla eqhweni elikhulu nasezifundeni ezibandayo. Isevisi yokuhlanza i-gutter yochwepheshe ingasiza, noma ezinye zezinkampani ezingcono kakhulu zokuhlanza uphahla zinikeza le sevisi. Kodwa kubanikazi bezindlu abakhetha ukwenza i-DIY, kubalulekile ukuthi ungashwibi esitebhisini futhi esikhundleni salokho usebenzise elinye lamathuluzi okuhlanza udoti angcono kakhulu njenge-AgiiMan Gutter Cleaner ukuze ususe ngokuphepha amaqabunga nemfucumfucu.
Uma zinganakwa, amadamu eqhwa angabangela umonakalo omkhulu endlini ngenxa yeqhwa ophahleni, okuhlanganisa ukucekelwa phansi kwama-shingles nama-gutters. Kukhona futhi ingozi yokulimala kwamanzi ezindaweni zangaphakathi kanye nokukhula kwesikhunta njengoba amanzi ekwazi ukuhlanganisana ngaphansi kwama-shingles futhi angene ekhaya. Abanikazi bezindlu kufanele balungele ukususa iqhwa uma kulindeleke iqhwa esikhathini esizayo esiseduze.
Ama-ice jams angancibilika ngamakhemikhali noma ngesitimu (noma ngezindlela zokuncibilikisa iqhwa ezingafaki usawoti noma amakhemikhali), noma angasuswa ngokomzimba ngokuhlephula izingcezu ezincane ngesikhathi. Lezi zindlela zisebenza kahle kakhulu (futhi ziphephile) uma zenziwa ochwepheshe. Kodwa-ke, inkambo engcono kakhulu yokwenza ngokuhamba kwesikhathi ukuvimbela amadamu eqhwa ukuthi angakheki kwasekuqaleni ngokufaka i-insulate yendlu, ukufaka umoya ofanele ophahleni, kanye nokufaka izintambo zokufudumeza ezizilawulayo. Lokhu kuzosiza ukusindisa izindleko zesikhathi esizayo zokususa iqhwa, ingasaphathwa eyokulungisa idamu leqhwa elonakele. Abanikazi bezindlu bangase bacabangele izindleko zokuqedela lokhu kuthuthukiswa njengotshalomali enanini lekhaya.
