Roof: I phama ophahleni, Khetha Material

Roof - kuyinto igobolondo ophahleni, esivikela ekwakheni ngokumelene Ukungena imvula. Roof kufanele kube manzi, ongaphakeme conductivity ezishisayo futhi amelana amakhemikhali nolaka futhi kwezulu. Ukuze yokukhiqiza i-ukufulela zisebenzisa izinto ezihlukahlukene - organic, metallic noma amaminerali. Ngalinye uhlobo ukufulela ukusebenza ehlukene kanye service yokuphila, abanye ingahlala iminyaka 5-7, futhi noma yiliphi 100. Cabanga uhlobo ngalunye ophahleni.

Organic.

Idatha ezintweni zokwakha uphahla aziwa izinkuni lasendulo, utshani, ezimise okwama-tile, kanye ngezinto zokwakha zesimanje - ibitume-polymer ingxube, iphuma izinto, i-asphalt, nezinye polymers.

buhle:

• zingabantu engasindi.

nebubi:

• wavuma simelane ultraviolet ray nakuma-oksijini,
• ukuguga okusheshayo,
• bakwazi ubole,
• kakhulu inflammable.

Impilo inkonzo engu-5 ukuya 30.

Amaminerali.

Lena iqembu elikhulu, okubandakanya slate Tile, Tile Ceramic usimende-isihlabathi, asbestos-usimende amashidi (asbestos) namathayili. Lezi izinto ukufulela kuthiwa ngokuthi yemvelo futhi.

buhle:

• okuhlala isikhathi eside
• okuthembekile
• musa ukubola,
• akusho okhela,
• asibhubhi kwelanga.

nebubi:

• Ngingu kakhulu sensitive lokushisa, ikakhulukazi kule ezahlukene zero degrees,
• abe nesisindo eside,
• akuvamile esetshenziswa ngenxa yezindleko kuqhathaniswa eliphezulu.

Metal.

Lezi zihlanganisa metal amashidi lukathayela, metal, ukufulela, izinsimbi non-ayoni. Ukuze zethusi yokukhiqiza zabo, aluminium, steel lashukumisa, futhi omnyama, kanye Alloys wayo, okungukuthi kudaywa ukuvenisha, lacquer, upende, polymer izinto. amashidi yethusi kukhona isikhathi eside kunazo zonke. Impilo ka-ophahleni ithusi iminyaka engu-50 kuya ku-100.

Yiba isisindo ongaphakeme. Lapho kwakhiwa kokusetshenziswa ezimbonini, emphakathini futhi commercial metal oqondile amashidi. Ngokuvamile, imishini uphahla ophahleni nge kumpambuko kusukela 14 kuya ku-20 degrees, amashidi nge ukushuba 0.5 - 0.8 mm, camera nhlangothi zombili zinc. Ukufakwa ishidi ukusonga metal ubuchwepheshe aphethwe, ngakho lokhu kubizwa ngokuthi ukuma umphetho ophahleni. Uphahla kufanele ifakwe izisebenzi ezinekhono kuphela. Bayanda Yaqala esikhundleni steel titanium, ithusi, aluminium. Yethusi, nakuba kuyabiza, kodwa ine oluvelele Inkulumo yezakhiwo kanye nokuqina kakhulu. Metal ukufulela eyenziwe ngensimbi lashukumisa, futhi ngezinye izikhathi wazenza ngethusi. Ingahle camera nge Ukuvikelwa ukugqwala ezengeziwe, Gxila kokukodwa noma okubili zamatshe enamathela polymeric. I enamathela polymeric olumelana imisebe ultraviolet amakhemikhali kungenzeka matt noma shiny. Metal okuhlala kanye engasindi, ibekwe phezu kophahla nge eyehlelayo mkhulu kunezinhliziyo degrees 12.
