FAQS

Are Fiberglass Windows Durable?

Fiberglass replacement windows are built to stand up to the Mid⁠-⁠Atlantic’s wide range of weather. They won’t warp, rot, or corrode, and they maintain their shape through extreme temperature swings, helping prevent drafts and seal failures. With their rugged construction and long-lasting finish, fiberglass windows are designed to perform beautifully for decades with minimal upkeep.

Are Fiberglass Windows Energy Efficient?

Fiberglass windows are naturally insulating and built to withstand temperature swings without expanding or contracting, which helps keep their seals tight over time. This stability reduces drafts and heat loss, while advanced glass options further improve insulation to keep your home comfortable year-round. The result is reliable energy performance that can help lower heating and cooling costs.

What Customization Options Are Available for Fiberglass Windows?

Pella fiberglass windows are highly customizable to match your home’s style. You can choose from a variety of colors and finishes, including low-maintenance, fade-resistant options, as well as different hardware styles, and window shapes. Whether you want a classic look or a modern design, fiberglass windows can be tailored to fit your vision while maintaining long-lasting performance.

What Are the Maintenance Needs for Fiberglass Windows?

Fiberglass windows are designed to be virtually maintenance-free. They never need painting or refinishing, and cleaning is simple, just use soap and water to keep them looking like new. Their durable construction and finish resist fading, chipping, and warping, so you can enjoy long-lasting beauty and performance with minimal effort.

What’s the Difference Between Vinyl vs. Fiberglass Windows?

Vinyl and fiberglass windows both offer energy efficiency and low maintenance, but they differ in strength, stability, and appearance. Vinyl is durable, affordable, and easy to care for, but it can expand or contract in extreme temperatures. Fiberglass, on the other hand, is stronger and more dimensionally stable, holding its shape through heat, cold, and humidity, which helps prevent drafts and seal issues. Fiberglass also allows for larger window sizes and more premium finishes, making it a great choice for homeowners seeking long-term performance and a high-end look.

How Long Do Fiberglass Windows Last?

Pella fiberglass windows are built for long-term performance and can last 30 years or more with minimal maintenance. Their durable construction resists warping, rotting, and corrosion, even in the Mid⁠-⁠Atlantic’s shifting weather. With their ability to maintain strength and stability over decades, fiberglass windows are a smart investment for homeowners who want lasting value.

How Much Do Fiberglass Windows Cost?

The cost of fiberglass windows can vary based on size, style, features, and installation needs. In general, they are priced higher than vinyl but offer greater strength, durability, and long-term performance, making them a worthwhile investment for many homeowners.
