(Continued from part 3.)
Day of total completion for the bow window... All glazing surfaces have been applied with Rain-X, which is an excellent surface treatment for all glass surfaces. The interior pine surfaces got a light sanding, a coat of wood primer, then two coats of latex enamel semi-gloss paint.
Pella has a nice fold-away crank feature and a convenient low-position locking lever that operates both latches simultaneously. The bugscreen has an extension knob that aligns with the slimshade adjustment knob. These are essentially triple-glazed units with the extra glazing panel over the slimshades. The fixed sashes have a U-factor of 0.27 (the lower the better) while the casement sashes are 0.30 — truly amazing performance. It's quite noticeable, too, like when standing at the window on a cold windy day or when a noisy vehicle drives by. This is truly a high-performance window.
