Updated September 2026 by Chris Horton. Product lines and warranty documents checked against Therma-Tru’s own website on 30 September 2026. A method for reading a Therma-Tru quote, not a verdict on the brand, a series or a contractor. How we research
A proposal says “Therma-Tru fiberglass entry door” and gives a total. A second proposal says the same words and gives a different total. The instinct is to treat the brand as the specification and compare the two numbers. It is not the specification. Therma-Tru sells several distinct door lines, in more than one skin material, and the warranty it offers depends on which parts are assembled around the slab. Two quotes that both say “Therma-Tru” can be pricing different doors, different frames, different finishes and different jobs. This page is the decoder for that.
Is this the right page for your quote?
This page assumes the quote in front of you names Therma-Tru. If you are still deciding between fiberglass and steel as materials, the fiberglass vs steel entry door page covers that decision, and this page does not repeat it. If your quote names no brand at all, start with the door replacement quote audit, which works for any manufacturer. If you have no quote yet, the front door replacement cost guide explains what drives a total.
“Therma-Tru” is a brand, not a door
On 30 September 2026, Therma-Tru’s door collections page presented four fiberglass families, Classic Craft, Fiber-Classic, Smooth-Star and Pulse, alongside its Profiles and Traditions steel doors. Its product menu also lists a Benchmark Collection and the Veris Collection. Each name narrows the product down. None of them, on its own, identifies the door being priced.
| Name on the quote | How Therma-Tru describes it | What the name still leaves open |
|---|---|---|
| Classic Craft (also written Classic-Craft) | Therma-Tru’s premium fiberglass series, now organized into three collections: Artíssa, Founders and Visionary. Therma-Tru says these draw on styles from the earlier American Style, Mahogany, Rustic and Canvas sub-collections. (Classic Craft page) | Which of the three collections, which door design, which grain or texture and which glass. A brochure or quote that still uses an older sub-collection name should be restated in current terms. |
| Fiber-Classic | Wood-grained fiberglass doors, in Mahogany or Oak grain. | Which grain, which design and which glass, and whether the door arrives factory-finished or unfinished. |
| Smooth-Star | Fiberglass doors with a smooth texture, in a wide range of styles, panel designs and sizes. | Which panel design and glass, and whether the paint is applied at the factory or left to the installer. |
| Pulse | A contemporary series of door and glass designs, grouped into three design approaches named Ari, Linea and Echo, supplied ready to stain or paint. (Pulse page) | The skin material. Therma-Tru’s residential warranty lists Pulse under both its fiberglass and its steel door systems, and its Benchmark page lists a Pulse fiberglass and steel ENERGY STAR chart. “Pulse” alone does not tell you which you are being quoted. |
| Profiles or Traditions | Therma-Tru’s steel doors. | Nothing about fiberglass. If a quote you expected to be fiberglass names either line, it is quoting steel. |
| Benchmark | A Therma-Tru collection that Therma-Tru says is sold exclusively through Lowe’s. (Benchmark page) | Which Benchmark door it is and which warranty document applies. Benchmark doors listed at Lowe’s link their own warranty guide, so do not assume the dealer-line documents apply. |
| Veris | Contemporary glass entry and patio systems (pivot, hinged, folding and sliding) that Therma-Tru describes as built from aluminum, stainless steel and polymer components, with their own warranty. (Veris page) | It is not a fiberglass line. A Veris quote and a fiberglass quote describe different products. |
There are no product photos on this page. UpgradeWorth only publishes manufacturer photography with written permission, and we do not have it for Therma-Tru. To see what each line looks like, use the official collection pages linked in the table.
Door or door system: the distinction that changes the warranty
Therma-Tru’s residential limited warranty draws a line that quotes rarely spell out. The version of that warranty hosted on Therma-Tru’s site (a revision dated December 2016; Therma-Tru’s warranties page links the current documents) says a door and a door system are different things. A door system is assembled by whoever supplies it, whether a builder, dealer, contractor or distributor, from a slab and separate components, and full door-system coverage depends on those components being genuine Therma-Tru parts.
Read against a quote, that document has five practical consequences:
- The frame affects coverage, not only durability. It lists primed pine and oak jambs, mullions and brickmould among parts the warranty does not cover. It also excludes rot, splitting or swelling that comes from a frame not sourced from Therma-Tru, while saying a third-party frame does not automatically void the rest of the warranty.
- Genuine components can be identified. The document shows a Therma-Tru logo on genuine hinges, weatherstrip and glass, and the current online claim form asks for photos of the glass watermark and the hinge stamp. You can check this on delivery day.
- Finishing has deadlines. It requires fiberglass door systems to be finished within six months of installation, bare wood surfaces to be finished much sooner, and all six sides of the door to be finished. If the door arrives unfinished, someone named on the quote has to own that job.
- Labor is excluded. Labor to remove, reinstall or refinish a door under a claim is not covered. Whether labor is covered at all is a matter for the installer’s workmanship warranty.
- Claims start with the seller. A claim goes first to the builder, dealer or contractor who installed or sold the door, so it matters who that is, in writing.
That revision also set different warranty periods for the fiberglass lines and the steel lines. Therma-Tru’s warranties page now links separate documents for a transferable full-system rider, the composite door frame, PrismaGuard factory finishing, flush-glazed glass and the Tru-Defense system. Terms change between revisions, so ask the seller for the current document that applies to the exact door system on your quote, and read that rather than a year count on a brochure.
The Therma-Tru Quote Identity Matrix
Put each quote next to the matrix and fill in one line at a time. It is split in two on purpose. Part A is the product Therma-Tru makes and ships, which you can check against Therma-Tru’s documents. Part B is the installation, which Therma-Tru does not perform and its warranty does not cover, so only the contractor’s paperwork can settle it. A quote can be precise on one half and silent on the other.
The verdict words are the ones used across UpgradeWorth’s door tools: Same (both quotes state it, identically), Different (both state it, differently), Unknown (at least one quote is silent) and Not comparable (the difference is large enough that the two totals are pricing different projects). A blank is never equal to the other quote’s answer. It is an Unknown, and it goes on the list of questions to send back.
Part A: the product Therma-Tru makes and ships
| Field | A complete quote states | Check it against | If the quotes differ | If a quote is silent |
|---|---|---|---|---|
| Series and collection | The line (Classic Craft, Fiber-Classic, Smooth-Star, Pulse, Profiles, Traditions, Benchmark) and, for Classic Craft, the collection (Artíssa, Founders or Visionary). | Therma-Tru’s collection pages. | Different. Not comparable if one quote is a steel line and the other fiberglass. | Unknown. The first question to send. |
| Door design | The design name or product code for the slab, including panel layout. | Therma-Tru’s online door search, or the order confirmation. | Different. | Unknown. Without it, nothing else on the quote can be checked. |
| Skin and texture | Fiberglass or steel, and smooth or a named wood grain. | The series page. For Pulse, confirm the skin separately. | Different, or Not comparable across skin materials. | Unknown. |
| Core | The core as stated on the product data for that door. | The product data sheet, not the series name. | Different. | Unknown. Do not infer it from the line. |
| Size, swing and handing | Slab size, inswing or outswing, left or right hand, and jamb depth. | Your own measurements and the exterior door measurement checker. | Not comparable if the sizes differ, because the quotes assume different openings. | Unknown. |
| Glass and lites | Glass design name, lite size, glass type, and how it is glazed (a lite frame or a flush-glazed unit). | Therma-Tru’s glass pages. Flush-glazed glass has its own warranty riders on the warranties page. | Different. Glass is often the largest single configuration difference on an entry door. | Unknown. |
| Sidelites and transom | How many, their widths, their glass, and whether they are Therma-Tru units in the same system as the door. | Therma-Tru’s sidelites and transoms page. | Not comparable if one quote has sidelites or a transom and the other does not. | Unknown. |
| Frame and brickmould | Therma-Tru’s composite frame, a Therma-Tru wood frame, or a frame from another source, with its material named. | Therma-Tru’s composite door frame page and its warranty rider. | Different, and often a large difference in both price and coverage. | Unknown, and a priority question. |
| Sill, weatherstrip, sweep, corner pads, hinges | That they are genuine Therma-Tru components, and which sill. | The warranty’s component list and the logos on the parts. | Different. | Unknown. Full system coverage depends on the answer. |
| Hardware prep and locking | Bore and backset, deadbolt prep, whether a multi-point locking system is included, and who supplies the handleset. | The order confirmation. The 2016 warranty revision warranted multi-point locking only on fiberglass doors. | Different. | Unknown. |
| Factory finish | PrismaGuard factory-applied stain or paint (with color), primed for paint, or unfinished for finishing on site. | Therma-Tru’s finishing pages and the PrismaGuard rider. | Different. A factory finish and a site finish carry different warranty documents. | Unknown, and it decides who owns the finishing deadline. |
| Energy and code documents | The NFRC or ENERGY STAR information for the exact configuration, and any product approval your local code requires. | Therma-Tru’s product approvals and ENERGY STAR charts, and the label on the delivered unit. | Different. | Unknown. Never assume a rating from the line name. |
Part B: the installation, which only the contractor can define
| Field | A complete quote states | If the quotes differ | If a quote is silent |
|---|---|---|---|
| Supply format | Slab only, prehung unit, or an assembled entry system with sidelites or a transom. | Not comparable. | Unknown. See slab vs prehung vs full-frame. |
| Who assembles the system | The dealer, distributor or installer who puts the slab, frame and components together. | Different. | Unknown. The warranty treats the assembler as the party who builds the system. |
| Removal scope | Slab only, door and frame, or frame, sill and trim out to the rough opening. | Not comparable until both quotes share a removal scope. | Unknown, and a priority question. |
| Opening modifications | Any resizing, header or framing work, and an allowance and unit price for rot or subfloor repair found on removal. | Not comparable if one quote changes the opening size. | Unknown. “As needed” with no price is open-ended. |
| Sill pan and flashing | The sill pan (a manufactured kit or site-formed) and the flashing method. | Different. | Unknown. The warranty excludes damage from inadequate flashing. |
| Interior casing and exterior trim | Reused, patched or new, the profile and material, and who paints it. | Different. | Unknown. |
| Site finishing | Who finishes an unfinished or primed door, with what product, and by when. | Different. | Unknown, and high priority if the door arrives unfinished. |
| Hardware installation | Who supplies and installs the lockset or handleset, and whether rekeying is included. | Different. | Unknown. |
| Disposal and cleanup | Old door and frame hauled away, and any fee. | Different. | Unknown. |
| Permit and inspection | Who determines whether one is needed, who pulls it and who pays. | Different. | Unknown. |
| Workmanship warranty | Years, what it covers (including labor on a product claim) and how to make a claim. | Different. | Unknown. The manufacturer warranty does not cover labor. |
| Warranty paperwork | Which Therma-Tru documents apply, who registers the product, and which riders the seller is claiming. | Different. | Unknown. A year count without a document is a label. |

Do not compare the totals yet if any of these is true
Each condition below means the two Therma-Tru quotes are not yet measuring the same project. Send them back for specification first.
A quote that clears these gates is not necessarily the better quote. It is a quote that has become comparable.
Brand name is not the specification: a ten-line check
- The line is named, and for Classic Craft, the collection.
- The door design or product code is written down.
- Fiberglass or steel is stated, not implied.
- Size, swing, handing and jamb depth match what you measured.
- Glass design, glass type and glazing method are named.
- Sidelites and transom are counted and described, or stated as none.
- The frame material and source are named.
- The quote states that the components are genuine Therma-Tru parts.
- The finish is named, and so is whoever applies it and by when.
- The installation scope, from removal to trim to disposal, is on the paper, not in the conversation.
Questions to send back when a line is missing
Copy the questions that match the blanks on your quote and send them in writing. Asking every contractor the same questions makes the answers comparable too.
When the product is not identified
- Which Therma-Tru line is this door, and, if it is Classic Craft, which collection?
- What is the design name or product code of the slab, and can you send the order confirmation or product page?
- Is the skin fiberglass or steel, and is it smooth or wood-grained?
When the configuration is missing
- What glass is in the door and any sidelites or transom, by design name and glass type, and is it flush-glazed or in a lite frame?
- What size, swing and handing are you ordering, and what jamb depth?
- Which NFRC or ENERGY STAR information applies to this exact configuration, and does it need a product approval where I live?
When the system is not described
- What frame is the door hung in: Therma-Tru’s composite frame, a Therma-Tru wood frame, or a frame from another supplier?
- Are the sill, weatherstrip, sweep, corner pads, hinges and glass genuine Therma-Tru components?
- Who assembles the door system, and which Therma-Tru warranty documents and riders will apply to it?
When the finish is not described
- Is the door factory-finished, primed or unfinished?
- If it is not factory-finished, who finishes it, with which product, and within what time of installation?
When the installation scope is missing
- Are you replacing the slab only, the door in its frame, or the frame, sill and trim down to the rough opening?
- What sill pan and flashing will you install?
- What is included if rot or damage is found when the old door comes out, and what is the price beyond that?
- What happens to the interior casing and exterior trim, and who paints them?
- What does your workmanship warranty cover, for how long, and does it include labor on a product claim?
What the brand name cannot tell you
Energy performance. Therma-Tru publishes ENERGY STAR qualification charts by product line, and qualification depends on the configuration, especially the glass. The number that applies is the one for the exact unit on your quote. Our ENERGY STAR door requirements page and NFRC label decoder show how to read it.
Storm and impact performance. Therma-Tru lists impact-rated products and product approvals separately from its collections, and an approval applies to the configuration that was tested. The residential warranty itself says it does not make a home hurricane-proof or impact-proof. If your code requires an approval, ask for the document that names your configuration.
Security. A series name is not a security rating. What matters is the lock, the strike, the frame and the fit on your opening. If a quote claims a rating, ask which product was tested and to what standard.
Price. This page publishes no national price for Therma-Tru doors, and none for any single line. The configuration and the installation scope set the total, and those are exactly what two quotes tend to differ on. Planning ranges for entry doors in general are in the door replacement cost calculator.

Common questions
Is Pulse a fiberglass door?
Not necessarily. Therma-Tru’s warranty documentation lists Pulse among both its fiberglass and its steel door systems. Ask the quote to state the skin material.
Are Classic Craft, Fiber-Classic and Smooth-Star just price tiers of the same door?
They are separate lines with different designs, textures and finishes, and Classic Craft is further divided into three collections. Treat a change of line as a change of product, and compare the matrix fields rather than a tier label.
Does the Therma-Tru warranty cover installation?
No. The residential warranty excludes labor to remove, reinstall or refinish the product, and Therma-Tru’s warranties page notes that its Tru-Defense rider does not warrant the workmanship of anyone who assembles or installs the system, including its certified installers. Installation is covered, if at all, by the contractor’s workmanship warranty.
Does a non-Therma-Tru frame void the warranty?
According to the warranty revision hosted on Therma-Tru’s site, not automatically. But frame-related rot, splitting or swelling from a third-party frame is excluded. Check the current document for your door system.
Is a Benchmark door the same as a Therma-Tru door from a dealer?
Benchmark is a Therma-Tru collection sold through Lowe’s, and Lowe’s listings link their own warranty guide. Compare the specific door, frame, glass and warranty document rather than the brand.
Should I ask for a Therma-Tru Certified Installer?
Therma-Tru runs a certified installer finder. Whatever the installer’s status, get the installation scope and workmanship warranty in writing, because the manufacturer warranty does not cover workmanship.
