Nothing beats fiberglass doors for value and performance.

Therma-Tru Entry doors are not only the brand that most builders prefer; they are also unmatched when it comes to warranties, in the industry.  Every line of doors we offer comes with a package of performance that is unrivaled in the industry. 

With a front door by Therma-Tru, not only will you see an increase in comfort, energy efficiency and performance, but you will also see an increase in curb appeal.

Our fiberglass entry doors will add beauty and security to your home. In fact, a study conducted by an independent research company-TNS- found that a home with an enhanced Therma-Tru entry way added to it's perceived value by as much as five times the cost of the door itself.

Our fiberglass doors simply outperform wood and steel doors. Check out the tabs below for more information and comparison charts - we think you will be impressed.

Beautifully crafted, energy efficient, secure, and easy to maintain - Therma-Tru fiberglass entry doors are a durable alternative to wood or steel; and the AccuGrain™ Technology simply gives the Classic Craft® line even more appeal.

Therma-Tru's impact rated products are a better way to protect your home against severe storm damage, including heavy winds, rain and flying debris. As with other Therma-Tru products they offer this without sacrificing beauty.

Impact Rated Glass with Lip-Lite Frame, which is a beautifully designed, scrolled frame that in unobtrusive and unlike other industrial -type frames that you will find on the market today. The Lip-Lite Frame allows for extra room between the frame and the lockset, which means your hardware options are almost endless. With a patent-pending screw cover channel that hides unsightly screws, you can be assured that your entryway will have that eye-catching curb appeal while standing up to all types of harsh weather.

Flush-Glazed Doors with Impact Rated Glass meet the Florida and international building codes. These doors feature our new impact rated glass assembled directly into the door, making the door and glass one solid piece. In addition, this new glass has been third party tested to withstand windborne debris. You now have the option of attractive, full-lite, flush-glazed, impact rated glass in a fiberglass door that withstands all types of severe weather.

AccuGrain® Technology

accugrain technology logo

What is AccuGrain® Technology? AccuGrain is a door casting process that uses multiple dies to produce different graining types to cast the appearance of real wood into our fiberglass doors. At a high-level, the process starts with building a wood door using select pieces of wood that have the graining and wood characteristics we want to reproduce. The wood is then enhanced using proprietary technology to aggrandize the natural graining depth on the wood before casting.

Then, with the graining technology, the final product undergoes multiple castings. This process, called random depth graining, combined with the multiple dies to produce various graining types, makes the fiberglass door virtually indistinguishable from real wood doors.

This gives you the beauty of a wood door with all the benefits of the fiberglass door -doors that will not split, crack or rot like real wood.

AccuGrain® Technology is available in each of the four Classic Craft Door Collections:

  • Mahogany Collection
  • Oak Collection
  • Rustic Collection
  • American Style Collection

With a wide variety of styles, textures, colors, shapes and caming options we provide glass packages that are researched in the market to ensure they are highly rated in consumer preference. With decades of experience and technical know-how, we create quality glass designs that deliver optimal performance.

Handcrafted and built with all-glass bevels, backed by a limited warranty when installed in a fiberglass door system to help ensure peace of mind if any issue should arise during or after installation and by using Low-E clear glass panes that are tempered to provide added safety we are the preferred brand among builders and remodelers.

Our Classic Craft glass is more than 10% wider compared to standard fiberglass doors, allowing more light into the home and creating a distinctive entryway.

Fiberglass lite frames are made with the same material as the door to blend seamlessly.

Classic Craft clear glass options are Low-E, providing long term energy efficiency.

All decorative and privacy glass options feature triple-pane construction that helps reduce outside noise while increasing energy efficiency. Our sidelites are flush-glazed, integrating the glass during the manufacturing process and eliminating the need for a separate lite frame while providing a high-performance weather seal.

Glass packages are dependent on the style of door selected. Packages shown here are in alphabetical order. Please see your selected door to find the glass packages available for that particular style door.  Please scroll past the decorative glass packages to find detailed information on the divided lites, grilles, impact rated glass, internal blinds, energy efficiency, flush-glazed glass, quality testing and the Lifetime Limited Warranty.

IMPORTANT: Privacy ratings are determined by the 1/2 lite size glass. As a result the amount of privacy/glass transparency may be more or less than indicated by the privacy rating, based on glass design and the size of the glass that's inserted into the door, sidelite, or transom. Glass design may differ from the depiction due to size of glass.

The glass is put through multiple rigorous tests to ensure that it will live up to even the toughest quality and performance expectations.

  • Slam Test: glass fitted door is opened and closed repeatedly. Our slam tests are performed to commercial standards, which are stricter than what is required for residential use, to help ensure the durability and performance of both the door and the glass.
  • Frost Point Test: glass is exposed to weather-like conditions to help verify that it does not allow moisture and condensation to get trapped inside, helping preserve the beauty and quality of the glass.


With a lot of emphasis placed on achieving the highest level of customer satisfaction, we offer a Limited Lifetime Warranty on our fiber glass door systems so that if any issue should arise during or after installation they will be addressed in a professional timely manner.
