Window 48" x 12" Double Pane Tempered Glass Low-E PVC Frame Horizontal Slider

Maintenance free PVC Frame will not peel, wrap or corrode, no painting needed. The glass is double pane, two panes of 3.2 mil thick TEMPERED Glass with a Low-E coating. Tempered Glass is needed for bathrooms in many states. The Low-E coating gives this window a 0.265 U-Value for exceptional insulation, and a VLT (visible light transmittance) of ~61%. Low-E minimizes the amount of harmful ultraviolet & infrared light that can pass through glass causing material within the home to fade. Please note the Low-E is not crystal clear, it will have a slight tint which is what gives you all the good qualities listed above. There is a flange that goes all the way around the window, with the flange being 1" from front to flange and 2" from flange to back. This window comes in many different sizes, please ask if you do not see your size listed.
