Classic-Craft is the top of the Therma-Tru line. Its skins use AccuGrain technology to reproduce the texture and detail of natural hardwoods more closely than standard fiberglass, in woodgrain collections such as Mahogany, Oak and Rustic plus a smooth, paint-ready collection for contemporary homes. Ball-bearing hinges and precision-fit weatherstripping are part of the system.
The doors are built around Therma-Tru's polyurethane foam core and sold as a complete entry system with sidelites, transoms and decorative or privacy glass. Factory PrismaGuard stain or paint finishes carry a 10-year limited finish warranty, and the door system itself carries a lifetime limited warranty that transfers once to a new owner.
In Minnesota this is the line for a front entry that should look like custom wood without wood's maintenance. Order it with Low-E glass in any lites and a factory finish, and have the sill adjusted so the bottom seal stays tight after the house moves through its first winter.

Insulation and energy performance in Minnesota
Classic-Craft slabs insulate with a full polyurethane foam core rather than the wood or thin steel skins of budget doors, and the frame, sill and weatherstrip are engineered as one system so the seal holds through Minnesota winters. For the cold, order Low-E glass in every lite, choose privacy or textured glass in triple-pane, and have the sill set so the sweep compresses evenly.
Glass packages
- Factory-coated Low-E glass: a thin coating reflects infrared and UV, keeping heat inside in winter
- Most decorative, privacy and textured glass is triple-pane for reduced heat flow
- Privacy and textured options include Satin Etch, Chord, Rainglass and Granite
- Advanta Lite Frame (2023): clear and privacy triple-pane Low-E options that meet ENERGY STAR in all 50 states
- More than 80 percent of Therma-Tru door and glass options are ENERGY STAR qualified and NFRC certified
Frame and sash
Fiberglass skins over a polyurethane foam core, rated by Therma-Tru at up to four times the insulating R-value of wood. Sold as a complete door system with matched frame, sill and precision-fit compression weatherstripping so the slab seals against the frame on all four sides.
Ratings
Therma-Tru states that more than 80 percent of its door and glass combinations are ENERGY STAR qualified and NFRC certified, with options that meet ENERGY STAR in all 50 states including the Northern zone; the exact U-factor depends on the glass area and lite package you pick.
What the install adds
On install day we set the frame on a sill pan, tape the frame to the housewrap, fill the rough-opening gap with low-expansion foam, and finish the interior with backer rod and sealant so the air barrier is continuous. Exterior joints get backer rod and a quality sealant, and we adjust the sill and strike so the weatherstrip compresses evenly all the way around.
