Zola Windows now offers its PanoramicView Lift & Slide with a completely frameless fixed glass portion. The operable sliding sash now has a sash width of only 3 1/2 inches but can carry an 8-foot-high by 10-foot-wide panel of glass. The product has a visible light transmittance of 71 percent. For improved energy performance, U=0.07 glazing is available. R-11 triple glazing is standard; dual glazing (Classic Clad, R-5) and quad glazing (R-15) are available. Airtightness also has been upgraded by incorporating a quadruple compression seal along the sides and head of the sliding sash, offering Passive House-level air sealing and gasket design. The hardware and track system is fully concealed, and the flush threshold is ADA compatible while being air, snow and watertight.
