Pella Impervia Fiberglass Window vs Marvin Essential Fiberglass Window

In this video, we compare two flagships of the window industry: #PellaImpervia and #MarvinEssential #FiberglassWindows. We look at the design differences, maintenance, and energy efficiency. We hope that after watching this video, you will be able to pick the right window for your house based on your goals.

I looked at both and bought Pella. I liked the slightly course finish which looked like wood. I could not distinguish Marvin Essential from other vinyl products. The sill design was another factor. Marvin had slightly better efficiency though. To each their own.

Definitely Pella has that interesting wood like texture, which gives you that satisfying wood feel

Can the fuzzy weatherstripping on the Impervia be replaced if it wears out in 5, 10, 15 years? Thanks

[@SidingWindowsWizardsLLC]

Yes it is possible to replace it

1. Are there differences in wind speed tolerance? 2. If you compare windows closer in size, is there still a difference in sash thickness? 3. Which do you think will last longer (seems like the Pella would last much longer with it's over built features)?

[@SidingWindowsWizardsLLC]

Both windows are wind resistant and tolerant. The sash thickness is the same on all sizes. Both windows have robust construction. With extra big windows Pella might be the way, but Marvin boasts pretty reliable frame and sash construction as well

I can't find anything about the marvin essentials having weepholes, and another recent video of an essentials install doesn't seem to show them. Are you sure that's the current design? Thanke!

[@SidingWindowsWizardsLLC]

We got this Marvin Essential sample in October of 2023, so it has to be the latest one. We did not hear about any updates from Marvin yet

[@fakeusername92]

Quick note on energy efficiency from a mechanical engineer and full time energy analyst: the conductivity of these windows is essentially identical because they are both double pane fiberglass options. That's going to be the vast majority of your energy efficiency impact. There is weather stripping on the Marvin window, just a bit less than the Pella.

[@fakeusername92]

Unless you're designing a Passive Haus, you're not going to be able to tell them difference, energy wise.

[@SidingWindowsWizardsLLC]

We do agree that fiberglass material is gonna do a superb job in energy efficiency, but that generous weatherstripping on Pella Impervia is gonna improve air infiltration ratings substantially

[@SidingWindowsWizardsLLC]

@@fakeusername92 We would disagree on that one. From our experience, extra insulation makes a home more quite, if the window is installed properly and shimmed

Marvin also makes Infinity by Marvin, which are also fiberglass composite windows. They are made at a different Marvin factory, and many think they are better than the Marvin Essential fiberglass windows, especially for more contemporary homes.

[@SidingWindowsWizardsLLC]

Integrity Window is a slightly better window. The major difference is that it has wood interior and fiberglass exterior, as well as more features and color options

[@Mark-rw3kw]

@@SidingWindowsWizardsLLC I don't believe it is correct that Infinity uses a wood interior material. From reading their company information (and other KZbin videos), Infinity by Marvin has a fiberglass exterior and a choice of two interior materials, those being fiberglass or "EverWood." According to Infinity, Everwood looks, feels, paints, and stains like wood, yet is made of an inorganic material for superior durability over real wood.

[@SidingWindowsWizardsLLC]

definitely it is as good as wood, but the warranty is the same like essential. It means that the manufacturer is not sure that Marvin Integrity is gonna perform better than Marvin Essential in the long run

[@Mark-rw3kw]

@@SidingWindowsWizardsLLC According to Marvin the Essential collection has fiberglass exteriors and interiors. So looks to me like both Marvin Essential and Integrity by Marvin are fiberglass. The only difference in material is that Integrity by Marvin also is available with a fiberglass exterior and composite material interior option (instead of all fiberglass) that looks like wood, but is not. So not sure why warranty would be different. Both should last a very long time.

[@SidingWindowsWizardsLLC]

@@Mark-rw3kw well, Marvin provides 10 years warranty on the frame for Integrity Windows and Essential Windows. That’s definitely a red flag. Nobody cares about the studies and claims by the company that their materials are the best, if they don’t support these claims with their money. If they are so sure that their materials and windows are the most reliable, why not provide 50 year warranty???

The Marvin Essential Fit and Finish is Unmatched. The Pella Impervia fiberglass looks like duck tape and is ruff. The Marvin Essential is Smooth and no imperfections.

[@SidingWindowsWizardsLLC]

Definitely, Marvin Essential Fiberglass has a more refined and premium feel

[@markstipulkoski1389]

Pella has a unnatural bumpy texture and Marvin is smooth.

[@SidingWindowsWizardsLLC]

Yes, Pella Impervia does have some kind of texture when you have a closer look
