Umphezulu we-nano eguquguqukayo yokugquma ubushushu ugqunywe ngumaleko welaphu le-fiberglass ekwaziyo ukumelana nobushushu obuphezulu kwaye wenziwe kwimilo yegridi enemisonto yobushushu obuphezulu.Inokuguquguquka okuthile kwaye inokufakwa kwimibhobho okanye indawo egobileyo.Ngelo xesha, i-thermal conductivity ephantsi kunomoya, kwaye ukusebenza kwayo kwe-thermal insulation ingcono ngamaxesha angama-3 ukuya kwe-4 kunezixhobo zendabuko.
Yeyona imathiriyeli yobushushu obuphezulu bobushushu obuphezulu.
