Igwebu lensimbi isakhiwo seselula esihlanganisa insimbi eqinile (imvamisa iyi-aluminium) enezimbotshana ezigcwele igesi ezihlanganisa ingxenye enkulu yevolumu. Izimbotshana zingavalwa (igwebu leseli elivaliwe) noma zixhunywe (igwebu elivulekile leseli). Isici esichazayo samagwebu ensimbi yi-porosity ephezulu: ngokuvamile kuphela i-5-25% yevolumu iyinsimbi eyisisekelo, okwenza lezi zinto zokukhanya kwe-ultralight. Amandla ezinto ezibonakalayo ngenxa yomthetho wesikwele-cube.

Amagwebu ensimbi ngokuvamile agcina izinto ezithile ezibonakalayo zesisekelo sawo. Igwebu elenziwe ngensimbi engashi lihlala lingashi futhi lingaphinda lisetshenziswe njengesisekelo. I-coefficient yayo yokunwetshwa kwe-thermal iyafana kuyilapho ukuqhutshwa kwe-thermal cishe kuncishisiwe.

Nakuba amalungelo obunikazi amaningi echaza izakhiwo ze-topological ezinokwenzeka, izinto zokwakha, nezindlela zokukhiqiza, amagwebu ensimbi awakwazi ukuthathwa njengempahla futhi bambalwa abakhiqizi bezentengiselwano abatholakala emhlabeni wonke.
