Did  you  know  that  on  a  door  with  traditional  butt  hinges,  70%  of  the  door  weight  is  on  the  top  hinge?  The  top  hinge  also  bears  the  brunt  of  abuse  when  doors  are  opened  beyond  the  stop  device,  resulting  in  kickback  shock  and  eventual  failure  of  the  hinge  and  damage  to  the  frame.  This  is  why  continuous  hinges  are  recommended  for  heavy  doors  and  for  situations  where  doors  are  exposed  to  misuse.  Continuous  hinges  reduce  the  factors  leading  to  hinge  failure  by  distributing  weight  evenly  so  wear  and  tear  to  the  frame  and  door  is  reduced  significantly.  

In  addition,  continuous  hinges:
•  Increase  security  and  reduce  vandalism  by  preventing  insertion  of  devices  between  the  door  and  frame
•  Ease  installation  by  providing  simple  alignment  of  electrical  transfers  and  of  monitoring  switches
•  Reduces  air  infiltration  by  creating  a  complete  seal  from  top  to  bottom  of  the  door  at  the  hinge  jamb
