Interested in Renewal by Andersen windows? We’ll be taking a closer look at the company’s offerings, shedding light on what makes them great choices.

3. PART 1 - INTRODUCING THE FIBREX FRAME - A RENEWAL BY ANDERSEN INNOVATION
Windows are the sum of their parts. In this case, Renewal by Andersen
windows are made up of two main parts working together to offer
reliable quality. The first of those parts is Fibrex, the windows’ frame
material. What is Fibrex and what can it do? This is is what we are here
to discuss.
GETTING TO KNOW FIBREX
Wood and vinyl are highly popular window frame materials, each with
their own advantages. Wood, for instance, is durable and strong and
highly prized for its aesthetic appeal. Vinyl, on the other hand, is more
affordable and easy to care for as it is low-maintenance. What Renewal
by Andersen did in creating Fibrex is to combine the features that made
woodandvinyltopchoices.Thismeantcomingupwithframingmaterial
that is durable but low-maintenance and affordable yet beautiful. The
result? Fibrex.
WHAT IT IS
Patented by Renewal by Andersen in 1992, Fibrex is a composite
material made of reclaimed wood fibers and thermoplastic polymers, a
combination that accounts for the material’s strength and appearance.
It looks like wood but isn’t so it’s not plagued by the usual problems
that wooden frames face. It is also not vinyl, but it has the affordability
and ease of maintenance that made the material a favorite.

4. PART 1 - INTRODUCING THE FIBREX FRAME - A RENEWAL BY ANDERSEN INNOVATION
WHAT IT CAN DO
As the combination of wood fibers and thermoplastic polymers made
Fibrex incredibly strong, it also made it possible for just little of the
material to be used on a window, allowing for narrower frames which
result in larger areas for glass. The bigger the glass area, the bigger the
view, which is an attractive feature for a lot of homeowners.
Unlikewoodandvinyltoo,Fibrexminimizesexpansionsandcontractions
that come with constant temperature changes, meaning the frame
materialdoesn’tdeteriorateasfast,allowingyoutoenjoyyourbeautiful,
functional window for a long time. Fibrex is coated as well with a special
polymer during production, which improves the framing material’s
durability, letting it resist cracking, peeling, blistering, rusting, and
corroding.
A sturdy frame also means weatherstripping stays tight, ensuring air
leakages are kept to a minimum. In fact, Fibrex insulates well just like
wood and vinyl, which is 700 times better than aluminum.

Fibrex is truly impressive but it is not alone in making Renewal by
Andersen windows top-notch. Head on over to Part 2 of this blog series
to learn more about the role of window glass.

6. PART 2 - THE LOWDOWN ON LOW-E WINDOW GLASS
In windows, glass occupies the biggest area, significantly affecting
overallperformance.RenewalbyAndersenunderstandshowimportant
this role played by window glass is, and so uses only top-quality glass
for its own windows called low-emissivity glass.
WHAT IS IT?
Low-E glass looks just like any other window glass except it is designed
to be energy-efficient, limiting the amount of heat that comes in
through a window without affecting the level of natural light streaming
through. At the same time, heat from inside your home is kept indoors.
Preventing outdoor heat from coming in and indoor heat from getting
out normalizes temperature in your home, keeping cooling and heating
needs stable. This means your HVAC system doesn’t have to work too
hard to keep you comfortable, preventing it from needlessly guzzling
power which will be reflected in your energy bill.
RENEWAL BY ANDERSEN LOW-E GLASS OPTIONS
As it is, low-E glass offers reliable performance. Renewal by Andersen
kicks things up a notch by improving low-E glass some more, coming
up with its own selection of window glass options to let homeowners
pick out the best one for them. These include:

Separately, Fibrex and low-E glass have their merits. In the last part of our
e-book series, we’ll be talking about how the two work together to provide
Renewal by Andersen with some of the best windows in the market.
High-Performance Low-E4 Glass
According to Renewal by Andersen, their
high-performance low-E4 glass is 45% more
efficient during the winter months and 56%
during summer. Additionally, the window
glass has the capability to block up to 84% of
harmful UV rays that can degrade the quality
of furniture, draperies, and artwork.
High-Performance Low-E4 SmartSun Glass
Themostenergy-efficientglassoptionoffered
by Renewal by Andersen, SmartSun glass has
higher efficiency ratings during summer at
70% and can block almost all the UV rays at
an astounding 95%. The SmartSun glass has
an extra microscopic layer of silver, which
explains its increased efficiency.
High-Performance Low-E4 Sun Glass
This glass option is similar in performance to
High-Performance Low-E4 Glass but features
a tinted coating that lowers the amount of
visible light passing through a window. This
provides added privacy, taking away the need
for window treatments that completely block
out light.

9. PART 3 - FIBREX AND LOW-E GLASS: THE ELEMENTS OF A GREAT WINDOW
With electricity costs spiking, energy efficiency increasingly became a
concern for many homeowners. Renewal by Andersen responded by
taking it upon itself to provide window options that don’t just address
the need for energy efficiency but still ensured that home aesthetics
are complemented as well. In fact, the company was named an Energy
Star Partner of the Year, signifying that its efforts at offering energy
efficiency to homeowners through its windows are very real.
FIBREX AND LOW-E4 GLASS: THE WINNING COMBO
Fibrex has long been a part of Renewal by Andersen windows but high-
performance low-E4 glass was a more recent addition. Regardless,
the two are now together and that means the company has found its
winning combo for energy efficiency. How do the two work together to
produce a good window? Let’s go back to the benefits that Fibrex and
low-E glass offer:
•Fibrexlooksandactslikewood, making it beautiful but durable, while
more affordable and easier to maintain like vinyl. It may be a composite
material but it performs just as well as wood and vinyl in the insulation
department, insulating 700 times more effectively than aluminum. This
means heat transfers through a window’s frame is kept to a minimum,
the same with air leakages, which Renewal by Andersen windows keep
at bay because of superior weatherstripping. Bonus: Fibrex is made
from reclaimed wood fibers, making the material an environmentally
sound choice.

10. PART 3 - FIBREX AND LOW-E GLASS: THE ELEMENTS OF A GREAT WINDOW
• Low-E glass (high-performance low-E4 glass, more specifically) also
prevents heat transfers, keeping indoor heat in and outdoor heat out.
It does so without affecting how much natural light is let in, making a
window fitted with low-E glass ideal for anyone looking to make the
most out of daylighting as well.
Now put all of these benefits together and wouldn’t you say you have
a winning combo? Just Fibrex or low-E glass alone can’t offer the same
advantages as the combination of the two. By using them together,
Renewal by Andersen made it possible for homeowners to enjoy
numerous benefits just by getting windows.
