Update: this Alside Sheffield window review has been updated in 2022.
Disclaimer: We recently started offering Alside windows (almost) nationwide for you to install yourself or with professional installation by the manufacturer. We do it all with no in-home salespeople. Details here.
Here we’ll be taking a look at the Alside Sheffield windows. The Sheffield windows used to sit near the top of the Alside window line. Very similar products are sold under various brand names including Alside Ultramaxx and Comfort World 6000 series. This doesn’t necessarily mean it’s a better window than the Alside Excalibur or the Alside Mezzo (their other common offerings), but it does mean it will likely cost more.
In comparison to the newest window in the Alside line, the Alside Mezzo window (which we reviewed recently), the Sheffield doesn’t compare very well except in a few specific situations. For example, the Alside Sheffield window is available with triple pane glass while the Mezzo window was not when initially launched. The Mezzo window now has this feature available so that leaves one less reason to buy the Sheffield model. Obviously this only matter to you if you’re a triple pane kind of person.
Another point of differentiation is the fact that the Sheffield window has a few extra pieces of weather stripping. This sounds good and the salesperson might tell a great story, but if you compare the air infiltration ratings you’ll see the Mezzo is typically better. This tells you the extra weather stripping on the Alside Sheffield isn’t doing you much good. It provides the salesperson a nice story to tell, but it doesn’t do much else.
The biggest drawback in my mind is that the Alside Sheffield window uses a much thicker frame which reduces the glass area considerably. If you’re looking at samples in person take a look at the thick frame, especially the sill, and decide if that’s what you want in your home.
Alside Sheffield vs Ultramaxx
The Alside Sheffield and the Alside Ultramaxx share the same frame and ALMOST all of the same parts. There are only 2 two differences between these 2 products. One is the type of sill. The Sheffield uses a sloped sill that allows water to run off and the Ultramaxx uses a pocket sill that drains water out through weep holes in the frame. There are advantages and disadvantages to both systems.
The second difference between the Sheffield vs the Ultramaxx is the lift rail on the sash. The Sheffield has a lift rail at the very top and at the very bottom. The Ultramaxx adds another in the middle of the window. Having trouble visualizing what I’m saying in this section? Don’t sweat it, these two windows are essentially the exact same product with different names.
To sum up the Alside Sheffield review I’ll say if you’re getting triple pane glass it’s a fine option. If you’re not this window does’t really make sense and you’ll be better off saving a few bucks with the Alside Mezzo.
