S\u00eb pari, le t\u00eb flasim p\u00ebr at\u00eb q\u00eb n\u00eb t\u00eb v\u00ebrtet\u00eb \u00ebsht\u00eb pllaka me fibra qeramike. Imagjinoni k\u00ebt\u00eb: n\u00eb thelb \u00ebsht\u00eb nj\u00eb panel i fort\u00eb i krijuar nga fibra tep\u00ebr t\u00eb holla alumine dhe silike. K\u00ebto nuk jan\u00eb fije pambuku t\u00eb p\u00ebrditshme; ato jan\u00eb thurur nga nj\u00eb p\u00ebrzierje e shkrir\u00eb e materialeve si balt\u00eb kaoline, alumin\u00eb e past\u00ebr dhe r\u00ebr\u00eb silike.

Ajo q\u00eb me t\u00eb v\u00ebrtet\u00eb e b\u00ebn k\u00ebt\u00eb material kaq t\u00eb ve\u00e7ant\u00eb jan\u00eb vetit\u00eb e tij termike t\u00eb jasht\u00ebzakonshme.

Kjo ndodh sepse fibrat kapin ajrin n\u00eb m\u00ebnyr\u00eb t\u00eb jasht\u00ebzakonshme, duke ofruar nj\u00eb konduktivitet termik jasht\u00ebzakonisht t\u00eb ul\u00ebt\u2014nd\u00ebrmjet 0.08 dhe 0.15 vat p\u00ebr met\u00ebr-Kelvin kur temperatura rritet. N\u00eb praktik\u00eb, kjo p\u00ebrkthehet n\u00eb kursime t\u00eb m\u00ebdha energjie.

Por rezistenca ndaj nxeht\u00ebsis\u00eb \u00ebsht\u00eb vet\u00ebm fillimi. K\u00ebto pllaka jan\u00eb nd\u00ebrtuar p\u00ebr t\u00eb zgjatur n\u00eb mjedise t\u00eb ashpra.

Tani, ku shfaqen k\u00ebta djem t\u00eb k\u00ebqij? Kudo n\u00eb industrit\u00eb me nxeht\u00ebsi t\u00eb lart\u00eb.

Sigurisht, asgj\u00eb nuk \u00ebsht\u00eb e p\u00ebrsosur.

N\u00eb an\u00ebn e gjelb\u00ebr, gj\u00ebrat po p\u00ebrmir\u00ebsohen.
