Why Choose Global Home Improvement for Fiberglass Windows?

When customers choose Marvin Fiberglass windows, they are not only receiving new windows that are aesthetically beautiful, windows that can make a room stand out like it never has before, but they are also receiving and reaping the benefits of energy efficient windows thanks to the different options of glass to choose from. With energy costs constantly fluctuating, it may be more important now than ever to invest in Energy Efficient Windows such as Fiberglass Windows from Marvin.

Energy Efficient Glass Options

Fiberglass windows are rapidly rising in popularity due to their incredible energy efficiency. Not only are the materials better for the environment than other designs, but the different types of glass available can also improve the efficiency of fiberglass.

Low E II glass, for example, reflects heat away from the building—keeping the building comfortable all year long. Other options, like LoĒ³-366 windows, offer excellent visibility while blocking up to 95 percent of the sun’s heat and radiation. Fiberglass is also an excellent option for those concerned with the environment as its production requires far less energy.

Fiberglass vs. Wood and Vinyl

While wood is known for its beauty and vinyl is popular for its price, the advantages of fiberglass are truly compelling and outpace the competition in almost every way that matters. In antique and historic homes, it’s never a bad idea to attempt to preserve wood windows. The problem with wood windows, however, is they’re notorious for being high maintenance. Wood windows require a lot of work and upkeep to make sure they’re functioning correctly and to prevent rotting, drying and cracking.

Vinyl, a versatile and inexpensive material, may not withstand harsh temperature shifts. Known for shrinking in cold weather and expanding to the point of cracking during hot summers, vinyl might be cheaper, but its inability to be repaired can lead to replacement costs. Aside from not being repairable, vinyl also can’t be painted.

Fiberglass is not only immune to the issues of wood, but it can be both repaired and painted several times over, making it a versatile and reliable material for windows. Because it can respond well to temperature changes, it can last longer and keep the outside elements where they belong.

Infinity EverWood Finish

Many people are unsure what to think when they hear about fiberglass windows. Everyone knows what both vinyl and wood look like, so when it comes to a new material, it’s understandable for some to be skeptical. But with the variety of paint and finishes available, fiberglass windows can fit just about any style.

With the Infinity Everwood Finish, it’s hard to find a reason to go with any other window design. This finish incorporates paint that mimics wood, right down to the very texture. In addition, it helps homeowners avoid the issues posed by wood. The Infinity Everwood Finish is the perfect combination of aesthetics and long-lasting durability.
