Chip and Joanna Gaines Launch ‘Timeless’ Siding Collection with James Hardie

Chip and Joanna Gaines are launching an exciting new home collection!

The Magnolia power couple teamed up with James Hardie, a home manufacturing company, to produce the perfect siding line for any homeowner’s next exterior makeover.

In an interview with PEOPLE, Joanna explains the reason why she loves partnering with James Hardie. “We drive by the homes we did 20 years ago down by Baylor University, and those were all Hardie-sided homes. This is truly a product that we’ve believed in for 20 years,” she says.

She adds that working with James Hardie was “a match made in heaven,” and that she and Chip felt “honored” to be collaborating with the company.

Chip tells PEOPLE, “We’ve always been really proud of the reality that we can put James Hardie siding on a project and know that 20 years later, we still feel a lot of pride in it instead of feeling like we have to shade our eyes because we’re embarrassed of how it looks years later.”

The Danger of Installing Vinyl Siding in Cold Climates

In a recent advertorial on JLC’s website, the author exclaims the virtues of solid PVC siding and trim, including “not having to add a rainscreen.” Yet the lack of a rainscreen (or enough continuous exterior insulation) with any polymer-based siding (including vinyl, “solid” PVC, and similar materials that do not vapor permeable) in residences can potentially cause serious and widespread moisture damage to wall sheathing and framing.

It has long been known that water vapor produced indoors can migrate by air leakage or vapor diffusion into walls and condense on the wood sheathing or the exterior portions of framing in cold climates. That commonly and naturally happens during wintry weather. During winter, the moisture content in sheathing rises and peaks, eventually falling again with warmer spring and summer weather. The key is that wood or similar siding or fiber-cement siding is vapor permeable (what some call “breathable”) and allows moisture in the sheathing to slowly but surely dry to the outside air. If it dries enough, the sheathing moisture content drops below the fiber saturation level of about 26% to 30%. Below this level, decay cannot occur during warm spring and summer weather.

Should I Pick Vinyl or Fiberglass Replacement Windows?


Choosing Between Vinyl and Fiberglass Replacement Windows: A Comprehensive Guide

You are not alone if you have difficulty deciding between vinyl or fiberglass replacement windows. Homeowners must consider a few essential things when choosing between vinyl and fiberglass windows, which is not always easy. Homeowners must assess strengths, durability, cost, aesthetics, and more. This article compares vinyl and fiberglass replacement windows, highlighting their pros and cons to help you make the right choice for your home, budget, and lifestyle.

Vinyl and Fiberglass Replacement Windows

When it comes to enhancing your home’s energy efficiency, aesthetic appeal, and overall comfort, selecting the right replacement windows is crucial. Two popular choices in the market, vinyl and fiberglass windows, each come with their unique set of advantages and considerations. In this article, we will compare the pros and cons of both options, empowering you to make an informed decision that aligns with your home, budget, and lifestyle.

Vinyl Replacement Windows: The Budget-Friendly Contender



Vinyl windows are often more budget-friendly than fiberglass alternatives, making them an attractive option for homeowners looking to upgrade without breaking the bank.

Low Maintenance

Known for their durability and resistance to elements like rot and corrosion, vinyl windows require minimal maintenance. They are resistant to peeling, fading, and warping, ensuring long-term aesthetics.


Vinyl windows offer excellent insulation, helping to regulate indoor temperatures and reduce energy costs. This can lead to a more comfortable living environment year-round.


Color Limitations

While available in a variety of colors, vinyl windows may have limitations when it comes to customization. Homeowners seeking a specific, unique shade may find their options somewhat restricted.

Structural Integrity

In extremely hot climates, vinyl windows may be prone to warping. Weather conditions in Colorado are a climate that can alter the shape and performance of vinyl windows within 2-5 years, making them a short term solution for your home.

Fiberglass Replacement Windows: The Premium Choice



Fiberglass windows, considered a composite window,  are exceptionally durable and resistant to warping, rotting, and corroding. They can withstand harsh Colorado weather conditions, making them ideal for our climate.

Strength and Stability

Fiberglass is known for its strength-to-weight ratio, providing windows with structural stability without compromising on aesthetics. This allows for larger, more expansive window designs with bigger daylight openings.


Fiberglass windows offer extensive customization options, allowing homeowners to choose from a wide range of styles, finishes, and colors. This makes them an ideal choice for those who prioritize design flexibility.



Fiberglass replacement windows are generally more expensive upfront compared to vinyl. However, many homeowners see this as a worthwhile investment due to the long-term benefits and durability.

Limited Availability

Although fiberglass windows are becoming more popular, they may not be as readily available as vinyl options in some markets. However, in Colorado, we are the oldest dealer of Infinity fiberglass windows.


The Bottom Line

You may not think much about window appearance – the whole point is to look through them, after all – but fiberglass and vinyl windows have some aesthetic differentiators worth noting. Fiberglass windows can be painted, customized upon purchase and closely mimic wood windows’ appearance. But if you want to paint vinyl windows, it’s not advised since they don’t hold paint well. They’re less stable than fiberglass and are more likely to warp.

Fiberglass windows are much more stable than vinyl ones, so they don’t need to be as wide. This means fiberglass frames have a smaller visible daylight opening- perfect for your home!  If more natural light and more versatile appearance options are important to you, consider fiberglass over vinyl.


Thinking of Replacing Your Windows?

Replacing your windows can be a great way to improve the look and feel of your home. Not only will your home look better, but you’ll also enjoy enhanced energy efficiency. If you’re thinking of replacing your windows, finish reading this article about fiberglass replacement windows. With these tips, you’ll be able to find the perfect windows for your home and get them installed quickly and easily! There are plenty of window materials, from vinyl to aluminum to wood. Perhaps the two most popular styles found on modern homes in the U.S. are vinyl and fiberglass. If you’re considering upgrading your windows soon, it’s fair to question which material will best fit your home. Some factors to consider are strength, durability, cost and energy efficiency.

In conclusion, the choice between vinyl and fiberglass replacement windows ultimately depends on your specific needs, preferences, and budget constraints. Assessing the pros and cons outlined in this article will guide you toward making a well-informed decision, ensuring your investment enhances both the beauty and functionality of your home for years to come.

The Power of Ultrex Fiberglass

Ultrex is a window framing material that is known for its strength and durability. It is considered the strongest material in the replacement industry and is able to resist bending and flexing better than Fibrex® and vinyl. Its incredible strength allows for narrower frames to be built, resulting in more expansive and breathtaking views. Ultrex fiberglass is an excellent material that exceeds expectations in many ways.

•These windows are strong and designed to hold their shape.
• They expand and contract at the same rate as glass, which is 87% less than vinyl.
• Most vinyl windows can change shape in temperatures as low as 100-120° and can deform permanently at 140°, but Infinity from Marvin fiberglass windows will not distort in temperatures up to 350°.
• This also means that the seals on these windows stay strong, and the windows do not lose their shape or energy efficiency over time.


If you're thinking of getting new windows, we highly recommend going for Infinity from Marvin instead of vinyl windows. Trust us, you won't regret it. The difference in quality and durability is remarkable.
