Chidzidzo cheCanada chekuongorora kushanda kwenguva refu kweyakawedzerwa polystyrene (EPS) mukubatana nevhu yakakurudzira vagadziri veEPS muNorth America neCanada kuti vataure kuti kuvhara kwakakodzera kushandiswa muvhu, zvakafanana nekushanda kweextruded polystyrene (XPS). ).
Zvadaro, zvichibva pauchapupu hwekukundikana kweshingle, zvidzidzo zvinotsigirwa neindasitiri zvakaratidza kuti kushanda kweXPS mumashandisirwo enyika chaiyo hakuenderane nekuongororwa kwerabhoritari, zvichiita kuti EPS ive chinhu chekutanga. Nepo indasitiri yeXPS yakaramba mhedzisiro iyi netsvagiridzo yavo, zvinonakidza kuti vagadziri veXPS vakachinja kutarisa kwavo kubva kune yakaderera hygroscopicity inocherechedzwa mukunyudzwa murabhoritari uye hunyoro hwemhepo kuenda kune hunyoro hwekuparadzira zvinhu zveXPS.
Kukundikana kwakawanda kweXPS kunokonzerwa nekuoma kwekugadzirisa shingle mamiriro uye kushandiswa kwezvinhu zvakasanganiswa nehurombo husina kunaka hwekudzivirira mvura. Pane humbowo hwekuti XPS iri nani kana pasina nemaune dhiraivha yakatenderedza uye pasi pekuvhara, ichipa hunyoro huzhinji kuramba kana wasangana nevhu.
EPS perimeter insulation yagara yakagadzikwa nebackfill yedhinari zvinhu, polyethylene yekudzivirira furo, uye mapombi ekudonhedza pasi pekuvhara. Nekudaro, XPS inongoiswa chete uchishandisa polyethylene membranes.
Kuumbwa kweEPS uye XPS insulation yachinja nekufamba kwenguva, semuenzaniso, maajenti ekuridza ezviviri zvinhu zvachinja. MuNorth America neCanada, XPS ikozvino inogadzirwa pasina ozone inopedza kuvhuvhuta vamiririri, asi izvi hazvisizvo kune imwe nzvimbo. Zvimwe zvigadzirwa zveXPS zvinotengeswa kunze kwenyika kuNew Zealand zvinoita kunge zvakaitwa nekucheka zvinhu zvakasununguka pane kuzviburitsa kubva mukukora kwedehwe. Iyo cuticle paXPS sheet inononoka kuchembera uye inobatsira zvikuru mukuchengetedza hunyoro.
BRANZ yakaedza chigadzirwa cheXPS chine kupisa kwemhepo kwe0.036 W/mK. Kusiyana neizvi, iyo conductivity yecarbon-filled polystyrene foam yakaderera zvakanyanya pane iyi kukosha. Mazhinji eiyo styrofoam inogadzirwa muNew Zealand ine zvinhu zvakadzokororwa uye dzimwe nguva inogona kuve neyakaomarara chimiro.
Kubvumira hunyoro kuti hupararire muvhu, zvakanaka kuti furo racho harifanire kuvharwa zvachose nechivharo chisingapindi mvura. Munguva yechando, chero hunyoro huri pasi pemadziro huchamanikidzwa kunze mukati mekuvhara kweperimeter, saka zviri nani kushandisa chivharo chemhepo kunze kwekudzivirira. Kana izvi zvisingabviri, furo rinofanira kupinda muvhu, richisiya chete chidziviriro chekudzivirira chepamusoro pezvikamu zvevhu.
Sezvo mutemo wakazara, mvura yemvura yenheyo haifaniri kunge yakanyanyisa, saka njodzi huru mukugadzirisa inobva kune capillary effect apo mvura inopinda pakati pekuvhara nekrete. Izvi zvinogona kudzivirirwa nekushandisa capillary break (eg butyl tepi) pamucheto wezasi we insulator.
Nyorera kuti ugamuchire nhau dzese, ongororo, zviwanikwa, wongororo uye maonero pamusoro pezvivakwa uye dhizaini yakananga kubhokisi rako rekunyora.
