We are Building Performance certified and offer a holistic approach to helping you maximize your home’s efficiency as affordably as possible.
Since its origin in 1983, fiberglass entry doors have become a popular choice for homeowners. By combining the finish of natural wood doors with the durability and energy efficiency that fiberglass provides, fiberglass doors are an excellent entryway door choice that will contribute beauty and convenience to your home. At Building Envelope Experts, our team is here to help you choose the best doors for your St. Louis home.
Some St. Louis homeowners choose fiberglass for their doors because they are:
- Energy Efficient: ProVia entry door systems contain a polyurethane core, high-performance, heat-resistant window trim, Q-Lon weatherstripping, and ComforTech Warm Edge Glazing System, all of which work together to prevent unwanted airflow into and out of your home. All glassless ProVia entry doors are ENERGY STAR certified and many models with glass also meet ENERGY STAR® standards.
- Low Maintenance: Fiberglass entry doors require the lowest maintenance of all exterior doors. Unlike other materials such as wood, fiberglass doors don't require ongoing maintenance such as resealing and painting. Fiberglass is also resistant to warping, rotting, and rusting, preserving the quality of your entry door despite the heavy traffic it encounters.
- Composed of Durable Materials: Fiberglass doors are incredibly durable and can last up to 20 years. Because of how long they last, ProVia fiberglass doors come with a Lifetime Limited Warranty that guarantees the doors through the entirety of the ownership of the home by the door purchaser, plus one subsequent homeowner. Paint and stain finishes are warranted for up to 10 years.
- Aesthetically Pleasing: When you choose a fiberglass entry door, you can choose from a number of finishes - including realistic wood grain texture and countless paint colors. Also, fiberglass doors offer the option for decorative door glass, which improves the curb appeal of your home.
