Fiberglass entry doors have changed what homeowners expect from a front door — and for a mix of historic and modern homes, the case for fiberglass is especially compelling.
Why Homeowners Choose Fiberglass Entry Doors:
- Rot and moisture resistance: Unlike wood, fiberglass doesn’t absorb water. Wet autumns and spring thaws that batter doors won’t degrade a fiberglass entry.
- Wood-look aesthetics without the maintenance: Fiberglass can be textured and painted to mimic real wood grain convincingly. Homes look authentic without the scraping and repainting cycle.
- Superior insulation: A polyurethane foam core inside a fiberglass door provides strong thermal resistance. Paired with the ComfortTech™ Warm Edge Glazing System, it holds heat where you want it.
- Color flexibility: Every fiberglass door from Coastal Windows & Exteriors can be finished in any color from the Sherwin Williams catalog, or matched to a custom color. Your door doesn’t have to look like everyone else’s on the block.
- Energy Star performance: Installing Energy Star certified doors can reduce heating and cooling costs by an average of up to 13% compared to non-certified products. Fiberglass ProVia doors consistently meet or exceed this bar.
- Durability in freeze-thaw cycles: Fiberglass expands and contracts at a rate closer to your home’s framing than steel or wood does. That means fewer gaps and better long-term seal performance.
- Design customization: Sidelights, glass panel designs, and hardware options let you build a front door that fits your personal style, from understated traditional to bold modern statement.
