Evaluating window material options

The best products are made from the best materials. Here is a list of common materials for replacement windows and doors.

Infinity’s ULTREX® Fiberglass

Our proprietary ULTREX® Fiberglass is an innovative material pioneered over 20 years ago, making it one of the first premium composites on the market. ULTREX® fiberglass replacement windows and doors continue to deliver strength, stability, and durability. Our proprietary acrylic finish is three times thicker than the competition.

Other fiberglass windows

The strength and durability of fiberglass make it a good option for replacement windows and doors. Not all fiberglass materials are the same — and finishes can vary across manufacturers. Some have poor mat finish’s and others are made very brittle and none have the strength durability and high quality of ULTREX®.

Infinity from Marvin is the only window manufacturers with the state of the art patented pultruded fiberglass process combined with the patented acrylic finish. The proprietary ULTREX® finish is the highest rated in the industry the first and the only one to have achieved AAMA 624 verification. That is why ULTREX® is the best choice for Del Mar window replacement.



While vinyl is frequently the cheapest option, vinyl windows and doors can warp, peel, shift, and crack under everyday conditions. Vinyl has the lowest ratings for Flexural Modulus and highest ratings for expansion and contraction. Vinyl will expand 8 times more than the glass that it surrounds which can lead to seal failure.


Wood windows offer more strength, stability, and beauty than vinyl, but they tend to require more maintenance than other window materials.

Vinyl/wood composites

Vinyl/wood composites like Fibrex® are made from vinyl infused with wood fibers (sawdust). Fibrex® isn’t fiberglass. Fibrex® is a registered trademark of Andersen Corporation.


Aluminum is stronger than most other materials used to manufacture windows except ULTREX® Aluminum does not crack or peel like vinyl and is paintable. There is not a lot of maintenance with aluminum windows. The challenge with an aluminum window replacement is it is not very attractive, it is a soft metal so it still expands 3 times more than the glass which can lead to seal failure and aluminum can also transfer the heat and cold which can defeat the purpose of effective energy efficiency. Click here to see how ULTREX compares to vinyl and other composite window materials.

Premium Quality

Infinity® products are designed to replicate the look of traditional wood windows and doors while providing modern features and low-maintenance performance. Made out of Ultrex®, Infinity®windows and doors are customized to meet your house’s needs of replacement windows while giving you the longevity and toughness to withstand the harsh California weather. All vinyl products distort in extreme heat or eventually chalk and crack in California’s sunny fluctuating temperatures. Infinity® window and door products offer the highest level of performance and are virtually maintenance-free due the patented Ultrex®material allowing you to do your replacement window project once.

Details Matter

Infinity® products incorporate the details of traditional wood windows without all the usual maintenance and failures of wood materials. The advanced design of Infinity® products combine easy cleaning features and effortless operation, making them an easy choice for busy homeowners! Our patented, co-adhesive bonded finish is up to 3x thicker than competitive painted finishes, and the Ultrex®coating system is AAMA 624-10 verified, meaning our commercial grade finish resists the harshest weather conditions Mother Nature offers; a claim our competitors can’t match.

Miranda D.

Our salesman and lead installer demonstrated extreme knowledge in the “infinity” line of windows. Installation of four windows went smoothly in one day. They made sure the windows opened easily before they left and were through with cleanup. Thanks

Peralta F.

The door was recommended by my son and they followed through on the most beautiful door. I was extremely satisfied that they finished it off so fast. The facing around the door looks really good. I used to have a drape pulled across the door but I threw it away because it’s a beautiful door and I like looking at it every day.
