810 series windows are designed for the view, with equal glass sightlines which present a balanced look between window vents. Available as custom picture windows, sliders, single hung windows or in combinations.They include all of the engineering, strength and efficiency of the 800 series with these added features:

•  Improved thermal performance adding extra comfort and savings.

•  Equal glass sightlines, for optimum grid pattern alignment.

•  Standard Mercer Crescent latch, which automatically locks when the vent is closed.

• Available as standard nail fin, stucco fin or Artisan™ fin frames with extra rigidity. The stucco fin shown to the left, can be inset into the frame of an existing window as a replacement, without disturbing stucco or siding.

* Cardinal XL Edge Dual Seal Insulated Glass Units without grids. “U” Factor:The rate of non solar heat loss or gain through a given glazing. The lower the number, the better the insulating quality. Solar Heat Gain Coefficient: The fraction of direct solar radiation that enters a building thru the glass as heat. Lower numbers mean the glazing lets less heat in. Visible Light Transmittance: Measures the amount of light transmitted through the glass. VT is expressed as a number between 0 and 1. The higher the VT, the more light is transmitted. 810 AAMA Certified Window Performance Ratings Glazing Type Test Size Rough Opening Vent Size AAMA Performance Rating Uniform Structural Load MPH 5 Gal/Ft/Hour=8"/Hr Water Resistance MPH Horizontal Slider           810 Horizontal Slider XO 72" x 60" 5" vent reinf. 36" x 60" HS-LC25 37.5 PSF = 123 MPH 4.5 PSF = 42 MPH AIR = .22 cfm/ft∧2           800CAL/810 Horizontal Slider XO 72" x 60" 4" vent reinf. 36" x 60" HS-C35 52.5 PSF = 145 MPH 5.25 PSF = 45 MPH AIR = .12 cfm/ft∧2           810 Horizontal Slider XOX 96" x 60" 24" x 60" HS-LC30 45 PSF = 134 MPH 4.5 PSF = 42 MPH AIR = .12 cfm/ft∧2 Single Hung           810 Single Hung 48" x 60" 48" x 30" H-LC35 52.5 PSF = 145 MPH 5.25 PSF = 45 MPH AIR = .17 cfm/ft∧2           810 Single Hung 48" x 78" 48" x 39" H-LC30 45 PSF = 122 MPH 4.5 PSF = 42 MPH AIR = .16 cfm/ft∧2           810 Single Hung 56" x 91" 54" x 45" H-LC25 37.5 PSF = 122 MPH 3.75 PSF = 38 MPH AIR = .14 cfm/ft∧2 Single Hung Pictures           810 Single Hung Pictures Window Single Hung 120" x 72" 30" SH H-LC30 45 PSF = 134 MPH 4.5 PSF = 42 MPH AIR = .14 cfm/ft∧2 Fixed Picture Window           810 Fixed Picture Window 96" x 72" F-AW50 75 PSF = 173 MPH 12 PSF = 69 MPH AIR = .01 cfm/ft∧2           810 Fixed Picture Window 96" x 60" F-C30 45 PSF = 134 MPH 12 PSF = 69 MPH AIR = .01 cfm/ft∧2
