Questions buyers ask
Does D.W. Ross sell Andersen, Marvin or Pella windows?
No. We do not sell Andersen, Marvin or Pella windows, and we are not a dealer for any of them. Our aluminum-clad wood line is Sierra Pacific, and D.W. Ross is a Sierra Pacific dealer.
What is the difference between extruded and roll-form aluminum cladding?
Extruded aluminum is pushed through a die into a shaped profile. Roll-form cladding is sheet aluminum bent to shape. Sierra Pacific says its extruded aluminum is twice as thick as roll-form cladding.
Is a vinyl or fiberglass exterior the same as aluminum-clad wood?
No. Each maker covers the wood with its own material. Andersen's 400 Series has a vinyl exterior, and Marvin's Elevate has an Ultrex fiberglass exterior. Read each maker's published materials for the line you are pricing.
Which clad-wood window is the best?
We do not rank other makers' windows. We sell Sierra Pacific, and its glass can generally be swapped without replacing the sash. That matters twenty years in.
Do you install the windows?
No. We supply them; the contractor doing the work installs them. If you don't have an installer, we can recommend one from our list of trusted contractors.
