Lithini ixabiso le-R le-insulation?

Ukuba uthengela i-insulation, mhlawumbi ufumene igama elithi "R-value."Kodwa yintoni kanye kanye?Kutheni le nto kubalulekile xa ukhetha into efanelekileyo yokugquma ikhaya lakho?

Ixabiso le-R le-insulator ngumlinganiselo wokumelana nobushushu.Ukubeka ngokulula, kubonisa indlela i-insulation echasene ngayo nokuhamba kobushushu.Okukhona liphezulu ixabiso le-R, kokukhona ukugquma kukugcina ushushu ebusika kwaye upholile ehlotyeni.

Ixabiso le-R yinto ebalulekileyo ekufuneka uyiqwalasele xa ukhetha ukugquma kwekhaya lakho.Inokukunceda ukuba uqikelele uhlobo oluchanekileyo kunye nomthamo wokugquma ofunekayo ukulawula ngokufanelekileyo ubushushu bekhaya lakho kunye nokunciphisa iindleko zamandla.

Iindawo ezahlukeneyo zekhaya lakho zinokufuna amaxabiso ahlukeneyo e-R, ngokuxhomekeke kwimozulu yakho kunye nobungakanani bobushushu obukhoyo.Umzekelo, ukugquma kwe-attic kufuna ixabiso eliphezulu le-R kune-insulation eludongeni kuba ubushushu buthanda ukunyuka kwaye bubaleke nge-attic.

ISebe lezaMandla lase-US libonelela ngezikhokelo zexabiso le-R ezisekelwe kummandla wemozulu.Ezi zikhokelo zinokunceda abaninimzi kunye nabakhi baqikelele i-R-value efanelekileyo yendawo yabo ethile.

Kwiimozulu ezibandayo, amaxabiso aphezulu e-R ayacetyiswa ukunciphisa ukulahleka kobushushu kunye nokunciphisa ukusetyenziswa kwamandla.Kwiimozulu ezifudumeleyo, ixabiso eliphantsi le-R linokwanela ukukhusela ukwanda kobushushu kunye nokugcina amaqondo obushushu angaphakathi akhululekile.

Kubalulekile ukuqaphela ukuba ixabiso le-R yinto enye ekufuneka iqwalaselwe xa ukhetha imathiriyeli yokugquma.Ezinye izinto ezinjengokumelana nokufuma, ukhuseleko lomlilo kunye neendleko zokufakela kufuneka ziqwalaselwe.

Kukho iintlobo ezininzi zemathiriyeli yokugquma ezikhoyo, nganye inexabiso layo elingu-R.I-Fiberglass, i-cellulose, ibhodi yogwebu, kunye ne-foam yokutshiza lolunye ukhetho oluqhelekileyo, nganye ibonelela ngeendlela ezahlukeneyo ze-R kunye neendlela zokufakela.

Xa uthelekisa izinto zokugquma, ungacingi nje kuphela i-R-value, kodwa kunye nokusebenza ngokubanzi kunye nexesha elide le-insulation material.Imathiriyeli ethile inokuba nexabiso eliphezulu le-R kodwa isenokungasebenzi kakuhle kwiimeko ezithile okanye ifune ulondolozo olungakumbi ekuhambeni kwexesha.

Ukongeza ekukhetheni imathiriyeli efanelekileyo yokugquma, ufakelo olululo lubalulekile ekwandiseni ukusebenza kwexabiso le-R yakho.Izikhewu, ukunyanzeliswa, kunye nokuvuza komoya konke kunokubeka esichengeni ukusebenza kwe-insulation, okukhokelela ekunciphiseni ukumelana nobushushu kunye nokusebenza kakuhle kwamandla.

Ukuqinisekisa ezona ziphumo zingcono, kuyacetyiswa ukuba udibane nekontraka enobuchule bokugquma into enokuthi ivavanye iimfuno ezikhethekileyo zekhaya lakho kwaye icebise olona hlobo lufanelekileyo lokugquma kunye nexabiso le-R.

Isishwankathelo, ixabiso le-R lezinto zokugquma lidlala indima ebalulekileyo ekumiseleni ukuxhathisa kwe-thermal kunye nokusebenza ngokubanzi ekulawuleni ubushushu bekhaya lakho.Ngokwazi ixabiso elicetyiswayo le-R yendawo okuyo kunye nokukhetha isigqubuthelo esifanelekileyo, unokuphucula ukusebenza kakuhle kwamandla, ukunciphisa iindleko zokufudumeza kunye nokupholisa, kunye nokudala imeko-bume ekhululekile yangaphakathi.
