IG Type = Insulated Glass TypeU-Factor – The U-factor is a rating given to a window based on how much heat loss it allows. A lower number is more energy efficient.SHGC – The Solar Heat Gain Coefficient is a number assigned to a window that tells you how much heat that window lets pass into your home from the sun.VLT – Visible Light Transmittance is a measure of how much light passes through a window. VLTs range from 0 (no light) to 1 (all light).CR – The higher the Condensation Resistance Factor a particular window or door product possesses, the better will be its resistance to condensation.R-Value = The higher the R-Value rating, the higher the insulating power

Enclose balance springs in rustproof cases, with jamb liner covers, from the top of the bottom sash to the head of the window unit. Balance covers shall be finished to match window frame finish and easily removable for field service. Balances also have an interlocking pivot bar, for integral frame alignment with sash for keeping window frames straight and true during installation.

Locking Device: Provide each window over 32 inches in width with two cam-action sweep sash locks. The sash has one continuous, integral lift rail at the bottom of the sash. Two tilt latches in the top of the sash allow for tilting in for exterior cleaning. The tilt latches are integrally mortised into the sash top rails for a clean appearance.

Glass and Glazing: Factory glazed 3/4″ insulating glass conforming to ASTM-E-2090, with warm edge seal spacer. Glazing shall be integral glazing type system with architectural back bedded glazing tape and designed to maintain a watertight seal between glass and sash frame.
