Why quoting is hard here

The quote has to capture the requirements that change the product, price and installation.

Configuration checks

1Handing and opening requirements affect the whole unit.

Reps and dealers need to establish swing, hinge side and the opening requirements before choosing the unit. A product can fit the opening while still being wrong for the application.

Requirements to check
  • Handing
  • Rough opening
  • Applicable egress rules, including IRC R310

2Glazing depends on the job.

The same product family can require different glass packages for climate, safety and impact resistance. Sellers need to know which packages the manufacturer supports for the project.

Requirements to check
  • NFRC ratings
  • Applicable IRC R308 provisions
  • Impact approvals such as a Miami-Dade NOA where required

3The buyer needs to see the selected combination.

Finish, grille pattern and glass choices are difficult to assess from option codes alone. A clear view of the configured unit helps the buyer check the choices before approving the quote.

Requirements to check
  • Configured appearance
  • Selected finish
  • Glass and grille options
Scope note.

These are configuration considerations, not a compliance certification. Applicable requirements depend on the product, project location and current standards. Confirm them with a qualified specialist.

What Threekit does about it

1

Ask about handing and egress in everyday language

Needs Analysis asks which way the door opens and which side the hinges sit on. It asks in the words a homeowner uses. Threekit writes the handing code, so reps and dealers do not have to select the code themselves. Enter a bedroom window under 5.7 square feet of net clear opening and Configure blocks it before the quote exists. The rejection names the rule, not an error code.

2

Apply glazing rules before pricing

Configure holds your glazing rules and applies them as the buyer picks. Load your climate zone table and your impact-rated units. The buyer then sees only glass packages you will build for that jobsite. Sellers spend less time checking which glass packages are available.

3

Show the configured unit before approval

Threekit renders the configured unit as it is picked, in the browser, with the grille pattern and the finish the buyer chose. There is no three-day wait and no separate render queue.

Work through a configuration

A 3-0 by 6-8 fiberglass entry door with two 12-inch sidelites, for a coastal Florida job. The unit needs impact glazing, a Miami-Dade NOA number on the submittal and a right hand inswing jamb. Threekit asks for the jobsite and the opening first, then shows only the door units that carry that NOA.
