In　conventional　glazing　windows　filled　with　phase　change　material　(PCM),　the　type　of　PCM　is　usually　chosen　as　a　solid-liquid　PCM,　resulting　the　potential　leakage　problems　in　its　implementation　which　hinder　its　engineering　applications.　Replacement　of　solid-liquid　PCM　with　solid-solid　PCM　(SSPCM)　in　PCM　glazing　window　is　proven　as　an　effective　way.　For　the　sake　of　providing　guidance　for　the　further　development　and　preparation　of　the　SSPCM　adopted　in　glazing　windows,　a　parametric　study　is　conducted　that　focuses　on　the　thermal　performance　of　the　SSPCM　glazing　window　for　various　PCM　thermal　and　optical　properties,　over　24　h　in　the　rigorous　cold　weather　of　Anda　City.　A　heat　transfer　model　of　the　multilayer　glazing　window　with　SSPCM　and　silica　aerogel　integration　is　developed,　and　the　obtained　results　show　that　both　the　melting　temperature　and　latent　heat　of　PCM　have　significant　impacts　on　the　thermal　performance　of　the　glazing　window,　while　the　absorption　coefficient　and　refractive　index　have　slight　effects　on.　Additionally,　the　optimal　melting　temperature,　latent　heat,　absorption　index,　and　refractive　index　of　SSPCM　varying　in　the　selected　property　ranges　are　found　as　18　degrees　C,　120　kJ/kg,　60　m(-1),　and　1.3,　respectively.
