I saw a house that has just been renovated and no iron grills was used. Unbreakable glass was used for all windows and the contractor told me the special glass is 2 layer glass and cannot be broken,so no need to install ugly iron grills. Are such glass windows really unbreakable ? How much do they cost ?

Is it costly ? And is it really as secure as iron grill ?

This is a U.S. company; do they sell their products here in Malaysia ? If yes, any outlets in Klang Valley ?

Wow ! Damn expensive ! If normal glass, maybe just RM500, so your glass is 20X more expensive !
