Instructions forBonding and Sealing Mineral Glass WindowsDescription of ApplicationDimensioning of AdhesiveThe direct glazing of mineral glass(toughened security glass) intoframes or directly into the hull ordeck, requires a full understandingof all the important principlesinvolved.and SealantThe dimensioning of the adhesiveand joint geometry must be carriedout in accordance with Sika’sbasic rules of calculation. If deckmovement is negligible thefollowing dimensions are132451324recommended.1 Mineral glass2 Ceramic coating3 Sikaflex ® -2964 Flange1 Mineral glass2 Ceramic coating3 Sikaflex ® -2964 Flange5 Edge ProtectionIt is essential that the glass meet allthe demands and standardsrequired for the intendedapplication. For insulation glass,total bonding consistency must beensured through the complete useof Sikaflex ® adhesives for all theinstallation, i.e. no silicones.The polyurethane adhesive bondface must also be protected againstGlass Window DimensioningJoint widthMinimal joint width (mm)4 8 12 16oktoo small0 1 2 3Largest window dimension (m)Glass Window DimensioningAdhesive thickness,tMinimal adhesive thickness,t (mm)4 6 8 10oktoo small0 1 2 3alumimiumSteelLargest dimension of the glass (m)UV radiation.
