Key Differences Between Rosati Windows And Renewal by Andersen
- Efficiency and Performance
When evaluating replacement windows, energy efficiency is often one of the top criteria homeowners consider.
This relates to how well the windows prevent heat loss in winter and heat gain in summer.
On the efficiency front, Andersen windows are better performers.
They utilize a high-tech glass coating called High-Performance Low-E4 that boosts U-Factors and Solar Heat Gain Coefficients well beyond ENERGY STAR requirements. Triple pane glass adds further insulation.
Rosati windows also offer low-E glass and triple panes on vinyl window units, meeting ENERGY STAR standards. So while good, they don’t insulate quite as well as Andersen’s proprietary glass technology.
If maximizing energy savings is your main goal, Andersen wins out. But Rosati still delivers efficient, dual pane windows suitable for any climate.
- Glass and Frame Materials
Andersen windows only come with a Fibrex composite frame, while Rosati uses vinyl, wood, aluminum or fiberglass depending on the series.
Fibrex offers strength, dent resistance and low maintenance benefits. It has a wood-like aesthetic. Vinyl frames from Rosati provide similar positives like durability and low-upkeep at lower price points.
When it comes to glass, Andersen’s High-Performance Low-E4 coating helps improve solar and UV protection. Both brands offer tempered glass for impact resistance.
So materials are high quality on both ends, with Andersen focusing on its exclusive Fibrex and Rosati offering more frame material choices.
- Style, Color and Hardware Options
A key difference between these two window brands is Rosati provides much more style customization with various combinations of frame types, operating styles (double hung, casement etc) and decorative glass.
Their Vista Elite series lets you design windows matching the architectural style of your home whether old world cottage or modern farmhouse.
There are complementary muntins, interior colors and hardware finishes to choose from.
By comparison, Renewal by Andersen limits you to casement, double hung and gliding windows in white or sandtone exterior colors.
No decorative grille inserts are available. The hardware and trim choices are also more limited compared to Rosati.
So if having windows perfectly matching your home’s aesthetics is a priority, Rosati offers more customization. Andersen Renewal windows still look nice, but style options are not as varied.
- Warranties
When you’re investing thousands into replacement windows, a good manufacturer’s warranty brings peace of mind. What do Rosati vs Andersen offer?
Andersen has a 20 year limited warranty on glass breakage and a 10 year limited warranty on installation services. The glass coverage cannot be transferred to a new homeowner.
Rosati provides a lifetime limited warranty on vinyl windows, meaning the frame and mechanical components are covered. Separate 20 year warranties may cover the glass and screen, transferable for 10 years.
So for vinyl windows specifically, Rosati offers better long term protection. But Andersen still provides satisfactory glass and installation warranties for the first decade after fitting.
Make sure to read all warranty terms carefully before making any purchase.
- Cost Comparison
As you might expect given the superior energy efficiency, Andersen windows come at a higher price point than Rosati. Their composite Fibrex frames and triple pane glass create a premium window.
Expect to budget $600-800 on average for a single Andersen unit installed. Their prices are fairly fixed wherever you live and whichever dealer you choose.
Rosati vinly windows range from around $300 on the low end to $700+ on the high end.
This gives you good flexibility whether working with a tighter budget or wanting extra features.
Regional pricing differences and sales may also apply.
There are more budget friendly lines like the Radiant and Parlux series.
Then higher end Elevate windows match Andersen prices while offering more aesthetic customization.
So while Andersen Renewal windows carry a reputation for quality, you pay more for that performance. Rosati offers competitive features for less depending on the series selected.
Best Uses for Each Brand
Based on these comparisons, here are the best applications for each brand:
Rosati windows are ideal if you want:
- A wide selection of styles and designs to match your home’s look
- Freedom to choose different frame materials (vinyl, wood, fiberglass)

Andersen Renewal windows are preferable for:
