SINGLE HUNG WINDOWS
Our single hung windows operate smoothly with block & tackle type spring balancers to counter the weight of the vent. Vents normally are ½ the height of the overall window size but can be made unequal if desired.

GLASS
Standard insulated glass units are constructed using "270" Low E, manufactured by Cardinal Glass and separated by a hollow welded aluminum dessicant filled spacer. Insulated units with either an aluminum spacer or SuperSpacer are edge sealed with H. B. Fuller butyl sealant.

FIXED WINDOWS
Because the insulated glass units are installed from the exterior of the window, we cut notches in the bottom corners of the sill glazing bead to allow any water that would bypass the bead to exit along the outside exterior of the frame.
