Slocomb 1143 Windows Reviews
The Slocomb 1143 window is the company's impact resistant vinyl series that includes the following features: night vent latch, an interlocking meeting rail, constant force balancing system, dual weatherstripping, heavy die cast locks, deeply pocketed head, a warm edge Duralite spacer, positive sloped sill, metal latches, tilt in sashes, and an aluminum meeting rail reinforcement.
While the 1143 model has some nice features, I'm not going to recommend this window as the long term value that other impact windows may offer. The reason is the performance numbers it throws up, particularly the U-factor and Air Infiltration numbers. I feel they are too high to recommend the Slocomb 1143 impact window to consumers who are looking to maximize their long term return on investment. Of all the Slocomb series, I would have to give the nod to the Windblocker 477 window.

Slocomb 1143 Window Ratings
The Slocomb 1143 double hung window with an SB70 glass with an argon fill will deliver a .34 U-value, .21 SHGC, .14 air infiltration, .47 visible transmittance, 55 condensation resistance, and has a design pressure of 50.
While a few of these numbers are good, including the DP50 and and 55 condensation resistance, the U-factor and the AI are worse than I would have thought for an impact window. It's a bit hard to endorse this hurricane rated window with performance numbers as low as this.
