Slocomb Protech 177 Windows Reviews

The Slocomb Protech 177 window is the company's less bulky premium vinyl window, as compared to the Slocomb Windblocker 477 series. The Slocomb Protech 177 includes the following standard features: .080" vinyl wall, 7/8" insulated glass, tilt sashes on its double hung, die cast cam lock, triple weatherstripping, positive sloped sill, warm edge spacer, night vent latch, aluminum reinforced meeting rail, and a constant force balance system (the block and tackle balance system is the preferred method).

The Protech 177 window can be ordered in an interior white or tan, as well as a natural oak or cherry woodgrain laminate. These woodgrain laminates will add to the base cost of the window. The exterior of the Protech 177 window is available in a white, tan, bronze, and cocoa.

I do hear a bit about this window from time to time, but I don't hear much. It looks to me (and this is without ever seeing or installing it) like a pretty solid middle-of-the-road vinyl window. The .09 air infiltration number is not overly impressive, but it's not bad either. I think I'd say if you can get the window at a competitive price point and you feel confident in the installer who will be doing the work, then the Slocomb Protech 177 window might be one to consider.

Slocomb Protech 177 Window Ratings

The Slocomb Protech 177 double hung window in the standard low-e glass with an argon fill will deliver a .27 U-value, .21 SHGC, .09 air infiltration, .49 visible tranmittance and a 49 condensation resistance. The window has an R4 rating. All in all, pretty decent numbers. The .09 AI is probably the most telling of all the numbers, anything between .10 and .05 is considered okay, while anything over this leaves something to be desired and anything under the number is considered good. So, that being said, the Slocomb 177 vinyl window is in that okay range in turns of how much air is getting through the window.

Protech 177 Window Warranty

The Slocomb 177 vinyl window should come with the same warranty that the company offers on all of their windows, but their websites doesn't mention many details.

Jim - Homeowner - May, 2020

Website Editor's Answer

Jim, the Slocomb 177 and Reliabilt 3900 are both okay to decent mid range windows. I'd put them in the same pool of window quality. If these are the windows you are considering, I'd make my decision based on the installation company reputation and reviews.

Slocomb 177 vs. American Craftsman 70 & Simonton 5050

How does the Slocomb 177 series compare to Simonton 5050 window or American Craftsman 70 series?

Ned - Homeowner - March, 2018

Website Editor's Answer

Teresa, the Slocomb Protech 177 is the superior window to either the Simonton 5050 or the American Craftsman 70. The Slocomb 177 double hung gets a .27 U-value, .09 air infiltration, and .49 visible tranmittance. The window also has an R4 rating. All in all, pretty decent numbers. The other two windows are entry level vinyl windows with much higher air infiltration numbers and are not made as well.
