Best Fiberglass Doors (Brands, Styles, & Features): Top Picks for 2025

When it’s time to upgrade your home’s exterior, few features make a bigger first impression than the front door. 

At doors.com, you’ll find an unbeatable range of fiberglass doors from leading brands like Therma-Tru, GlassCraft, and Hoelscher.

Whether you’re looking for brand recognition with Therma-Tru or prefer the high-quality craftsmanship and better price points offered by GlassCraft and Hoelscher, you’ll find stylish options that fit your needs and budget. 

From classic panel styles to arched and round-top designs, fiberglass doors offer outstanding durability, energy efficiency, and curb appeal.

Before you make your purchase, it’s important to know what factors matter most. Let’s dive into it.

Fiberglass Door Buying Guide: 5 Factors to Consider Before Buying

Before buying a fiberglass door for your home, it's important to bear in mind a few factors. Let’s take a look at these:

1. Door Style: Choose a Look That Matches Your Home

The style of your fiberglass door sets the tone for your home’s entire exterior. Are you looking for a traditional paneled door, a modern flush style, or a rustic farmhouse look?

Therma-Tru is known for its broad style range, from classic Craftsman to sleek contemporary designs.

Meanwhile, GlassCraft and Hoelscher specialize in unique options like arched and round-top doors, which create a custom, high-end feel without the custom price tag.

Pro Tip: Match your door style to your home's architectural type for maximum curb appeal and resale value.

2. Size and Configuration: Fit Matters

When it comes to doors, one size doesn’t fit all. You’ll need to consider whether you want:

• A single entry door for a streamlined, classic look

• A double-entry door for a grand, open statement

• A custom-sized door to perfectly fit unique openings

At doors.com, many models, especially from GlassCraft and Hoelscher, are available in custom dimensions, so you don’t have to compromise on fit or style.

3. Energy Efficiency: Save Money on Utility Bills

Fiberglass doors are naturally excellent insulators. Look for models with:

• Polyurethane foam cores for maximum thermal performance

• Double- or triple-pane glass inserts if you want windowed designs

• ENERGY STAR® ratings, especially important for colder climates

Therma-Tru’s Smooth-Star® and Classic-Craft® lines lead the way in energy efficiency, while GlassCraft offers eco-friendly insulated cores as standard in many of its models.

4. Durability: Invest in a Door That Lasts

Unlike wood, fiberglass doesn’t rot, warp, or crack — even in extreme climates.

• GlassCraft fiberglass doors are known for their thick construction and impact resistance.

• Hoelscher doors are built to resist dents, scratches, and weathering over time.

• Therma-Tru doors combine composite rails and edges for superior moisture protection.

This means less maintenance and longer-lasting beauty for your home’s entrance.

5. Price vs. Value: Get the Most for Your Money

Therma-Tru is a household name for a reason — they combine beauty and performance in one trusted package. However, savvy shoppers often turn to GlassCraft and Hoelscher for high-end looks and durability at better prices.

If you're looking for maximum bang for your buck, especially for arched or specialty doors, it’s hard to beat GlassCraft and Hoelscher.
