Roof: The marulelo molomong, Khetha Material

Roof - ke khetla ea marulelong, eo ho sireletsa haha khahlanong le ho kenella ka hare tsa pula. Roof e lokela ho ba sa keneleng metsi, le tlaase mogote conductivity le manganga ho lik'hemik'hale mabifi le pula. Bakeng sa ho etsa thepa ea ho rulela sebelisa thepa e sa tšoaneng - manyolo, metallic kapa matsoai. E mong le e mofuta oa ho rulela fapaneng tshebetso le tšebeletso ea bophelo, ba bang ba ka ba teng ka lilemo tse 5-7, 'me leha e le efe le ho 100. Nahana ka mefuta e le batho ka bomong e marulelong.

Manyolo.

thepa ya data ho rulela li tsejoa ho patsi ea boholo-holo, litlhaka, shingles, hammoho le thepa ea kajeno - sekontiri-polymer motsoako, phuthoa thepa, sekontiri, 'me polymers tse ling.

melemo:

• ba bobebe.

tlhoka mesola:

• length of hanela mahlaseli mahlaseli le oksijene,
• botsofali le tiile,
• kgona ho bola,
• inflammable la bohlokoa haholo.

Bophelo tšebeletso ea lilemo tse 5 ho ea ho 30.

Matsoai.

Sena ke sehlopha se seholo, e kenyeletsang letlapa lithaele, lithaele ceramic le samente-lehlabathe, maqephe asbestos-samente (asbestos) le lithaele. Tsena thepa rulela ba boetse o bitsoa tlhaho.

melemo:

• tsoarellang
• ka tšeptjoang
• u se ke ua bola,
• ha e hotetsa,
• ha re timetsoe ke khanya ea letsatsi.

tlhoka mesola:

• Ke hlokolosi haholo ho mocheso, haholo-holo ka mefuta e fapaneng ya likhato lefela,
• ba le boima haholo,
• ha a atisa ho sebelisa ka lebaka la litšenyehelo batlang e phahameng.

Metal.

Tsena li akarelletsa tšepe masenke maqephe, tšepe, ho rulela, tšepe batho bao e seng ferrous. Bakeng sa ho etsa thepa ea koporo bona, aluminium, galvanized tšepe, 'me batho ba batsho, hammoho le lits'epe tse kopantsoeng lona, tse dailoeng thepa varnish, lacquer, pente, polymer. Koporo maqephe ke tsoarellang ho fetisisa. Bophelo ba marulelong koporo tloha ka ba lilemo li 50 ho ea ho 100.

Ba le boima haholo. Ka kaho ea liindasteri, setjhaba le khoebo sebelisoa maqephe a ka ho toba tšepe. Ka tloaelo ho, ka thepa ea marulelong a marulelo le ramp tloha ho likhato tse 14 ho ea ho 20, maqephe a nang le tsona ka botenya ba 0.5 - 0,8 limilimithara, a tlotsitsoeng ka mahlakoreng a mabeli le zinki. Tlhomamiso theknoloji lakane tšepe phutha tšoaroa, kahoo sena se bitsoa kotelamaka seam marulelong. Marulelong tlameha ho a hlomelloa ka ho basebetsi ba feela ba nang le tsebo. Ka ho eketsehileng ho ile ka qala ho nka sebaka sa tšepe le thaethaniamo, koporo, aluminium. Koporo, le hoja ho ke bitsa chelete e ngata, empa e na le e ikhethang meralo le ho hlahisa maikutlo le durability babatsehang. Metal rulela entseng ho tloha galvanized tšepe, 'me ka linako tse ling entsoe ka koporo. Ho ka 'na ba a tlotsitsoeng ka tlatsetso ya tshireletso ts'enyeho, ka le dikarolo le' ngoe kapa tse peli tsa barbotage polymeric. The barbotage polymeric e manganga ho mahlaseli mahlaseli le lik'hemik'hale tse ka 'na ba Mat kapa benyang. Metal tsoarellang le bobebe, e beha ka holim'a teraka le letsoapong e moholo ho likhato 12.
