Marvin Fiberglass and Fiberglass Doors

Marvin fiberglass doors are designed with a high concentration of fiberglass and strong resin, for a stylish door that not only looks beautiful but performs at the highest levels of thermal efficiency. Available in two varieties of fiberglass – Ultrex, and Marvin’s patent-pending High-Density fiberglass – Marvin is certain to have the perfect fit for your living space. With its minimal conductivity, fiberglass is one of the best insulators among door-frame materials. Fiberglass shrinks and expands at the same rate as glass, allowing for a tight seal and long-term stability which guarantees that fiberglass will perform like new for decades.

Benefits of Fiberglass

• High-Density fiberglass maintains shape and maximum thermal efficiency even in the harshest climates
• Available in Ultrex pultruded fiberglass – engineered to preserve its look even decades after installation
• Both High-Density and Ultrex pultruded fiberglass expand and contract at a rate comparable to glass to help ensure optimal performance over time
• Resistant to chipping, chalking or fading, even in darker colors
• Proprietary frame design provides strength and durability
