Leliphi Iphepha Lophahla Elona Ligqwesileyo?

Ukukhetha eyona nto ifanelekileyo yophahla sisigqibo esibalulekileyo esichaphazela kakhulu ubomi obude, ukusebenza kakuhle kwamandla, kunye nesibheno sobuhle besakhiwo. Imarike inikeza uluhlu olwahlukeneyo lwe iinketho zamaphepha okuphahla , nganye ineempawu ezahlukileyo ezilungiselelwe iimeko ezithile zokusingqongileyo kunye neemfuno zoyilo. Olu hlalutyo lubanzi luvavanya amashiti ophahla ahlukeneyo, ukuhlola izixhobo zabo, iingenelo, iintsilelo, kunye nezicelo ezifanelekileyo zokukhokela abachaphazelekayo ekwenzeni ukhetho olunolwazi.

Amashiti okufulela ngesinyithi

Iishiti zokufulela zeAluminiyam

Amashiti okufulela ialuminiyam adume ngobukhaphukhaphu kunye nokuxhathisa okukhethekileyo ekudlekeni. Ubunzima obumalunga neepounds ezi-5 ngonyawo lwesikwere, babeka umthwalo ongaphantsi kolwakhiwo xa kuthelekiswa nezinto zemveli. I-aluminiyam ngokwemvelo yenza umaleko we-oxide okhuselayo, ophucula ukuqina kwayo, ngakumbi kwimimandla eselunxwemeni apho ukubola kwamanzi etyuwa kuxhaphakile. Ngokutsho kwe-Aluminium Association, uphahla lwe-aluminium lunokuhlala iminyaka engama-50 kunye nokugcinwa okuncinci. Ukongezelela, ukubonakalisa kwabo okuphezulu-ukuya kwi-90% yemitha yelanga-inegalelo ekusebenzeni kwamandla ngokunciphisa iindleko zokupholisa kwiindawo ezishushu.

Iishiti zophahla zentsimbi

Amaphepha okufulela esinyithi ngamacangci entsimbi agqunywe ngomaleko we-zinc ngokusebenzisa inkqubo yokudipha eshushu, ebonelela ngomqobo owomeleleyo wokungadleki. I-zinc isebenza njenge-anode yombingelelo, ikhusela intsimbi engaphantsi nangona i-surface ikhutshwe. Olu hlobo lokuphahla luyindleko kwaye lunika ubomi be-25 ukuya kwi-60 iminyaka, kuxhomekeke kwizinto ezisingqongileyo. Uphando oluvela kuMbutho weSizwe weeNjineli ze-Corrosion lubonisa ukuba iingubo zokugqoka kwiindawo zasemaphandleni zinokukhusela intsimbi ngaphezu kweminyaka engamashumi amahlanu. Ukufumaneka kwabo kunye nokufikeleleka kwabo kubenza ukuba babe lukhetho oludumileyo kwiindawo zokuhlala kunye nezorhwebo.

Iishiti zophahla zentsimbi

Amaphepha ophahla lwentsimbi ayaziwa ngamandla abo kunye nokuguquguquka. Bangakwazi ukumelana neemeko zemozulu ezibi kakhulu, kuquka imithwalo enzima yekhephu kunye nemimoya ephezulu ukuya kwi-140 mph. Izinto ezintsha ezifana ne-Galvalume-ingubo ye-zinc kunye ne-aluminium-iphucula ukuxhathisa kwentsimbi. Uphononongo olwenziwa yi-Metal Construction Association lubonisa ukuba uphahla lwensimbi ye-Galvalume lunokuhlala iminyaka engama-60. Uphahla lwentsimbi lukwawonga amandla xa lugqunywe ngemiphetho ekhanyayo, nto leyo enokunciphisa iindleko zokupholisa ukuya kuthi ga kwi-25%. Ziyakwazi ukurisayikilishwa, zilungelelaniswe nezenzo zokwakha ezizinzileyo.

Iishiti zophahla ze-Aluzinc

Amaphepha ophahla lwe-Aluzinc aqukethe insimbi ehlanganiswe ne-alloy ye-55% ye-aluminium, i-43.4% ye-zinc, kunye ne-silicon ye-1.6%. Olu qulunqo ludibanisa ukuxhathisa ukubola kwe-aluminium kunye nokukhuselwa kwe-galvanic ye-zinc. Uphahla lwe-Aluzinc lubonisa ukusebenza okuphezulu kwiindawo ezibuhlungu, kubandakanywa neendawo zoshishino kunye nolwandle. Uphando lubonisa ukuba iingubo ze-Aluzinc zingahlala zide zibe ziphindwe kane kune-galvanization yendabuko. Ukubonakaliswa kwabo kwe-thermal kunciphisa ukuhanjiswa kobushushu, ukuphucula induduzo yangaphakathi. Ukudibanisa ukuqina kunye nokusebenza kakuhle kwamandla kwenza i-Aluzinc ibe yinto ekhethekileyo yokukhetha izicelo zexesha elide.

Amaphepha ePlastiki okufulela

Iishiti zophahla zePVC

I-PVC (i-Polyvinyl Chloride) ii-roofing sheets zisisombululo esikhaphukhaphu kunye neendleko ezisebenzayo eziqhelekileyo ezisetyenziswa kwezolimo, izakhiwo kunye nezakhiwo zokuhlala. Zinika ukuxhathisa okulungileyo kweekhemikhali kwaye zikhuselekile kwi-corrosion kunye nokubola. Uphahla lwePVC kulula ukulufaka kwaye lufuna ukulungiswa okuncinci. Nangona kunjalo, abanako ukubonelela ngenqanaba elifanayo lokuqina njengophahla lwentsimbi phantsi kweemeko zemozulu ezimbi. Ukuqhubela phambili kwimveliso kukhokelele ekuqinisweni kweemveliso zophahla zePVC eziphucula amandla kunye nobomi, zizenze zilungele uluhlu olubanzi lwezicelo.

Iishiti zophahla zePolycarbonate

Amaphepha ophahla ePolycarbonate ayaziwa ngokuxhathisa kwawo okungaqhelekanga kunye nokungafihli, okuvumela ukuya kuthi ga kwi-90% yokuhanjiswa kokukhanya. Zifanelekile kwizakhiwo ezifuna ukukhanya kwendalo, njengezindlu zokugcina izityalo, izibane zezulu, kunye neecarports. Ipolycarbonate yomelele kangangama-200 kuneglasi kwaye inokumelana nobushushu obugqithisileyo ukusuka ku -40°F ukuya kuma-240°F. Iingubo ezimelana ne-UV zomeleza ukomelela kwazo ngokuthintela ukonakaliswa kokuvezwa lilanga. Naphezu kweenzuzo zabo, uphahla lwe-polycarbonate lunokubiza kakhulu kunezinye iinketho zeplastiki kwaye zinokwandisa okanye zivumelane ngokuguquguquka kweqondo lokushisa, ezifuna ukufakwa ngokucophelela.

Uhlalutyo lokuthelekisa

Xa uthelekisa izinto zokuphahla, izinto ezininzi kufuneka ziqwalaselwe:

• Ukuqina: Uphahla lwentsimbi, ngakumbi ezo zenziwe ngentsimbi, i-aluminiyam, okanye i-Aluzinc, zinika ubomi obude obuphezulu, kaninzi budlula iminyaka engama-50.

• Iindleko: Iintsimbi ezenziwe ngesinyithi kunye namashiti okuphahla ePVC afikeleleka ngakumbi ngaphambili kodwa anokuba neendleko eziphezulu zokulondolozwa kwexesha elide.

• Impembelelo yokusiNgqongileyo: Iintsimbi zokufulela ziyakwazi ukurisayiklishwa kwaye zinokuba negalelo ekusebenzeni kakuhle kwamandla, ngelixa iiplastiki ezikhethiweyo zisenokungahambelani nokusingqongileyo.

• I-Aesthetics: Uphahla lwentsimbi lubonelela ngeendlela ezahlukeneyo zokugqitywa kunye neeprofayili, ukunyusa ukubhenela kwezakhiwo, ngelixa amashidi e-polycarbonate anikezela ngeendlela ezikhethekileyo ezicacileyo okanye eziguquguqukayo.

• Ukufakela kunye noLondolozo: Izinto ezilula ezifana ne-aluminium kunye ne-PVC kulula ukuyifaka, ukunciphisa iindleko zabasebenzi.

Izifundo

Uphononongo olwenziwe yiCool Roof Rating Council lubonise ukuba i-aluminiyam kunye nophahla lwentsimbi kunye neengubo ezikhanyayo zinciphisa kakhulu iziqithi zobushushu ezidolophini. Kwizicelo zokuhlala, abaninimzi babika ukonga amandla ukuya kuthi ga kwi-20% emva kokufaka uphahla lwentsimbi ekhanyayo. Izibonelelo zemizi-mveliso ezisebenzisa amaphepha okuphahla e-Aluzinc ziye zaqaphela ubude bokuphila okwandisiweyo kunye nokunciphisa inkcitho yokugcina. Kwiimeko zezolimo, ukuphahla kwe-polycarbonate kuye kwaphucula ukukhula kwezityalo ngokwandisa ukukhanya kwendalo ngelixa kunika indawo yokuhlala.

Iimbono zeNgcali

Iingcali zezakhiwo zigxininisa ukubaluleka kokukhetha izinto zokuphahla ngokusekelwe kwiimfuno ezithile zeprojekthi. UDkt. Emily Sanders, ingcali yokwakha ezinzileyo, ithi, 'Ukukhetha izinto ezifanelekileyo zokuphahla kubandakanya ukulinganisa iindleko zokuqala kunye neenzuzo zexesha elide. Uphahla lwentsimbi, ngelixa lubiza kakhulu ngaphambili, lunikeza ukuqina okungenakulinganiswa kunye nokusebenza kwamandla. ' Ngokufanayo, injineli yokwakha uJohn Mitchell igxininisa, 'Ngokuba izakhiwo kwiindawo eziqhekezayo' zibonelela ngenkonzo yokukhusela uphahla, izixhobo ezifana ne-Aluzinc inikezela ubomi obungcono kakhulu kunye nokukhusela.

Ukuqukumbela

Ukumisela elona cwecwe lokuphahla lixhomekeke kwizinto ezahlukeneyo ezibandakanya iimeko zokusingqongileyo, imiqobo yohlahlo lwabiwo-mali, iimfuno zesakhiwo, kunye nokukhethwa kobuhle. Iintsimbi zokufulela iintsimbi ezifana ne-aluminium, isinyithi, isinyithi, kunye ne-Aluzinc zinika ukuqina kunye nokusebenza kakuhle kwamandla, okwenza ukuba zilungele ubuninzi bezicelo. Iinketho zeplastiki ezifana ne-PVC kunye ne-polycarbonate sheeting sheets zibonelela ngezixazululo ezingabizi kwaye zikhaphukhaphu kwiimfuno ezithile, ngakumbi apho ukukhanya kwendalo kufunwa khona. Ukubonisana neengcali zeshishini kunye nokuqwalasela iimpawu ezizodwa zesakhiwo kubalulekile ekwenzeni ukhetho olufanelekileyo. Kwabo bafuna amandla aphezulu, iinketho zokunganyangeki komhlwa, ukuhlola iimveliso zophahla lwentsimbi zinokubonelela ngexabiso lexesha elide.
