Ukhetho lwe Iglasi yeprofayile ifuna isigwebo esibanzi esisekwe kwimilinganiselo emininzi efana nezidingo zomsebenzi wokwakha, iimfuno zokusebenza, uhlahlo lwabiwo-mali lweendleko, kunye nokulungelelaniswa kofakelo. Usukelo olungaboniyo lweeparamitha okanye amaxabiso kufuneka luthintelwe, kwaye undoqo unokuqhutywa ujikeleze le milinganiselo ilandelayo:

1. Cacisa iMiqathango yeSicelo esinguNdoqo: Ukulungelelanisa neeMfuno zokuSebenza kweZakhiwo

Iimeko ezahlukeneyo zokwakha zinomohluko omkhulu kwizinto eziphambili ekusebenzeni kwazoIglasi yeprofayile. Kuyimfuneko ukuchonga kuqala imeko yesicelo kwaye emva koko wenze ukhetho olujoliswe kuyo.

2. IiParameters zokuSebenza eziphambili: Ziphephe "Iintsilelo zeNtsebenzo"

Ukusebenza kweIglasi yeprofayileichaphazela ngqo amava okwakha, kwaye ezi parameters ezi-4 zilandelayo zifuna ingqalelo egxininisiweyo:

Ukutyeba kunye namandla oomatshini

Ubukhulu obuqhelekileyo yi-6mm, 7mm, kunye ne-8mm. Kwiindonga zangaphandle / iimeko ezinkulu, i-8mm okanye iglasi engqindilili iyakhethwa (inika ukuxhathisa okuphezulu komthwalo womoya kunye namandla okugoba).

Kwiindawo ezineenyawo eziphakamileyo (umzekelo, iipaseji zevenkile), kuyacetyiswa ukuba ukhetheIglasi yeprofayilengonyango olunomsindo. Amandla ayo eempembelelo ngama-3-5 amaxesha eglasi eqhelekileyo, kwaye iqhekeka ibe ngamasuntswana abuthuntu, iqinisekisa ukhuseleko oluphezulu.

I-Thermal Insulation (U-Ixabiso)

Ixabiso le-U elisezantsi libonisa ukugquma kwe-thermal okungcono (ukuthintela ubushushu ehlotyeni kunye nokugcina ubushushu ebusika).

Iglasi yeprofayile ye-U eqhelekileyo inexabiso le-U elimalunga ne-0.49-0.6 W/(㎡・K). Kwimimandla ebandayo esemantla okanye izakhiwo ezineemfuno eziphezulu zokonga amandla (umzekelo, iiprojekthi zezatifikethi ze-LEED zokwakha eziluhlaza), iglasi yeprofayili ye-U efakwe i-insulated iyacetyiswa (ixabiso layo le-U linokuba liphantsi njenge-0.19-0.3 W/(㎡・K)), okanye inokudityaniswa ne-Low-E yokwambathisa ukuqhubela phambili ukomeleza ukugquma kwe-thermal.

Ukugqunywa kwesandi (STC Rating)

Iglasi yeprofayile ye-U eqhelekileyo ineKlasi yoThutho lweSandi (STC) yokulinganisa malunga ne-35-40. Kwiimeko ezineemfuno eziphezulu zokugquma isandi, ezifana nezakhiwo ezijongene nesitrato kunye neewadi zesibhedlele, iglasi yeprofayili ye-laminated U iyimfuneko. Ukulinganisa kwayo kwe-STC kunokufikelela ngaphezu kwe-43, ukugqithisa iindonga eziqhelekileyo zezitena. Kungenjalo, isiphumo sokugquma isandi sinokuphuculwa ngokudityaniswa kwe “glass + sealant + keel” (izikhewu ziyindawo ebuthathaka yokuvala isandi, ngoko ke ingqwalasela eyodwa kufuneka ihlawulwe ekufakweni kokutywinwa).

Ibhalansi phakathi koThutho lokuKhanya kunye noMfihlo

Kwiimeko ezifuna "ukukhanya ngaphandle kokucaca" (umzekelo, izahlulo zeofisi), khetha iglasi yeprofayili eneepatheni ye-U okanye iglasi yeprofayile ye-U enengcingo. Ezi ntlobo zisasaza ukukhanya kunye nokubonakala kwebhloko.

Kwiimeko ezifuna "ukuhanjiswa kokukhanya okuphezulu + ubuhle" (umzekelo, iifestile ezibonisa urhwebo), khetha iglasi yeprofayile ye-U ecace gca. Ukuhanjiswa kokukhanya kwayo yi-10% -15% ephezulu kuneyeglasi eqhelekileyo, engenambala oluhlaza okotshani, okukhokelela kwisiphumo esibonakalayo esicacileyo.

3. Izinto eziphathekayo kunye noBugcisa: Khetha iMathiriyeli "efanelekile kuMfanekiso"

Izinto kunye nobugcisa beglasi yeprofayile yeU ichaphazela ngqo inkangeleko yayo kunye nokuqina, ngoko ke ukhetho kufuneka lusekelweiimfuno ezikhethekileyo:

4. Iinkcazo kunye nemilinganiselo: ukuFakela ukuFakela kunye neSakhiwo soKwakha

Iinkcukacha zeIglasi yeprofayileKufuneka zihambelane nokuvuleka kwezakhiwo kunye nesithuba phakathi kweekeel ukunqanda "ukusika inkunkuma" okanye "ukungafani kolwakhiwo":

Iimpawu eziqhelekileyo: Ububanzi obusezantsi (ububanzi bokuvula obumise u-U): 232mm, 262mm, 331mm, 498mm; Ukuphakama kweFlange (ubude bamacala amabini e-U-shape): 41mm, 60mm.

Imigaqo yoKhetho:

Ukubaluleka kufuneka kunikwe "kwizinto eziqhelekileyo" (umz., 262mm ububanzi obusezantsi). Babiza i-15% -20% ngaphantsi kweenkcazo ezenziwe ngokwezifiso kwaye banomjikelezo omfutshane wokuhambisa.

Kwizakhiwo ezinobubanzi obukhulu (umzekelo, iindonga zangaphandle eziimitha ezi-8), qinisekisa "ubude obuninzi bokuvelisa" kunye nomenzi. Ubude obuqhelekileyo obubodwa busuka kwi-6 ukuya kwi-12 yeemitha; ubude obude obude bufuna ukwenziwa ngokwezifiso, kwaye ukulungeleka kokuthutha kunye nofakelo kufuneka kuthathelwe ingqalelo.

Ukuhambelana nesakhelo:Iglasi yeprofayileidinga ukufakwa kunye neeprofayili ze-aluminium okanye iifreyimu zensimbi ezingenasici. Xa ukhetha iinkcukacha, qinisekisa ukuba “ubude beflange yeglasi” buhambelana neslot sekhadi lesakhelo (umzekelo, iflange eyi-41mm ihambelana nobubanzi bekhadi le-42-43mm) ukunqanda ukukhululeka okanye ukusilela kokufakela.
