Hard to say. I’d put i n the Marvin and replace the Andersen if it bothers you.

I would need to see where they are going and when asking this it is best to show pictures of both windows I for one dislike having to go searching to see what you are talking about. Usually all windows should be the same IMO.

If you plan on replacing more. I would go with Marvin. Renewals are very expensive .

Back in 2016 I had my windows replaced by Renewal By Andersen. According to the NFRC number AND-N-28 is considered an insert window. When they installed the windows which were double hung type windows, they completely removed the old windows down to the studs along with removing the interior trim and sill. My house is brick exterior and inside the house are plaster walls. They capped the outside along with installing new trim and new window sills. They secured the windows using screws on each side of the jambs into the studs. I did not loose any glass area like you would just doing a normal insert replacement installation, so my question is what type of installation would this type be called? I ask this because, like Simply Great Windows stated: Renewal does not normally install full frame replacements and the NFRC does indicate these are insert type windows not full frame replacements.

"they completely removed the old windows down to the studs along with removing the interior trim and sill."

That being the case you received full framed windows not inserts. Inserts or replacement windows fit inside your current window frame utilizing the complete frame including the sill.

Thanks millworkman,

I was confused only because the NFRC product directory shows that AND-N-28 under Andersen Corp is considered an insert window and not a full frame window.

Yeah, Andersen started making a full frames version of the Renewal window some time ago and they still market Renewal as a replacement window so it can get confusing. Still terribly over priced......................

@Kathleen, if you could post a picture of the home and note the locations it would be helpful. I agree with the sentiment that uniformity is best (both product and install type), however replacing all of the windows in your home just to match one that you no longer prefer doesn't make a ton of sense either... There are ways to minimize differences in appearance from the exterior, but it also depends if these are right next to each other (or across the wall), size differences, etc.

@Ron, you had the full frame of your old window removed and replaced with a new window of the same size, but without a nail fin and the subsequent flashing/sealing practices that are normally associated with a new construction/full frame installation. This is not preferred by most, however its also not without precedent and is generally accepted. I believe that Pella in particular refers to it as their "express" installation. Basically they took a window designed for replacement (3 1/4" frame depth and no nail fin) and installed to replace the full frame. There is a lot of gray area between the basic terms "pocket" and "full frame", and this falls within that. Closer to a full frame by definition, but again, without some of the added layers that are most often implied with that verbiage.

Finally got a carpenter who is installing full frame inserts MARVIN INTEGRITY or “essential” by Marvin. I like Marvin Ultrex BUT their window names/specs are very confusing. Andersen is easier to spec out.

Thank you all for your helpful comments!!

Insert or full frame?

i think the confusion in Marvin is due to the fact that the just rebranded their lines and changed the names. They actually have fewer models and a simpler hierarchy than Andersen IMO, things will likely seem less confusing once everyone uses the new names consistently.
