2.02.2 Glass Make-UpOuter pane: ___ mm tempered or heat strengthened float glass withInterpane I Plus e low-e coating on surface #2 (or other coating asagreed).Cavity: 16 mm with 8 mm _____ (air, argon or krypton) filled cavity and 8mm PMMA acrylic UV stable capillary slab encased in fiber tissue.Capillaries are not to exceed 3 mm diameter to assure properdiffusion.Inner pane: ___ mm tempered, heat strengthened or laminated float glasswith 1.50 mm PVB interlayer.Sealant:Dual sealed units:Primary sealant: PolyisobutyleneSecondary sealant: Polysulfide (Capped Systems for framedglazing)Silicone (Uncapped systems for structural glazing)Note: Silicone secondary sealants are notavailable with argon or krypton filled units due tomuch higher gas loss rates.Calculations: Glass make-up and thickness to be confirmed by glazing contractorand façade engineer to meet project load and local coderequirements.Size:Okalux® Plus, when supplied without a white inner mullion,has a maximum dimension of 1220 mm x 3500 mm. Whenboth of the dimensions exceed 1220 mm, a white innermullion is required to stabilize the capillary slab within theinsulated unit. Maximum dimensions with the white innermullion are 2000 mm x 3500 mm.2.02.3 Performance ValuesOkalux® light diffusing glass insulating glass shall perform optically andthermally based upon the following:Light Transmission ________45% maximumSHGC (TSET)________0.38 maximumU-value ________air 0.28; argon 0.24; krypton 0.18(Btu/hr/sf/°F)

Part 3. Execution3.013.01.1 ExaminationThe glazing contractor shall examine the framing and glazing channelsurfaces and backing as well as the conditions under which the glazing isto be performed.
