Slocomb Windstopper Windows Reviews
The Slocomb Windstopper window is the company's top-of-the-line series and is often called the WindBlocker series. Actually, I think WindowBlocker is the actual name and WindStopper was the previous model that many still use to refer to the series. If you look this window up, it comes up under Newton Windows, I'm assuming this company bought out Slocomb, but I could be wrong. (Please email if you know the answer to this so we can updtae the site.)
The company is part of the Earthwise Window And Doors group, which is an independent group of manufacturers who pool resources for their window assemblage, marketing, etc. In general, the windows that many of the Earthwise participants produce are considered pretty solid middle-of-the-road vinyl windows. (Not so much for their entry level windows, but their mid range and premium models.)
Standard features on the Windblocker 477 window include a 0.080" vinyl extrusion, an interlocking meeting rail, constant force balancing system, a composite reinforced meeting rail, a positive sloped sill, night vent latch, triple strength weatherstripping, and tilt sashes on the double and single hung models.

Slocomb Windstopper Ratings
The Slocomb Windstopper window with the low-e glass and argon fills should deliver a U-factor of .26, an R-Value of 4, and SHGC of 0.19, an Air Infiltration of .08, and a DP55 rating.
All in all, pretty darn solid numbers. The .08 AI isn't fantastic, but it's not bad either. I couldn't find them listed on the nfrc.org websites, which always kind of bugs me. If a company wants to claim numbers on their website, they should be listed on this site, along with the thousand of so other window manufacturers.
