Barrington is Masonite's premium woodgrain fiberglass collection: authentic, architecturally correct details with distinct raised mouldings and panel profiles embossed the way they would be milled on a real wood door, in mahogany or oak grain texture. Styles fall into three families: Craftsman, Sierra and Flagstaff, and Traditional, and glazed designs use Masonite's specialty decorative glass.
Stained, it reads as a custom wood door; underneath it is Masonite's polyurethane-core fiberglass with square-edge construction, hung as a Performance Door System. Masonite covers the Barrington slab with a limited lifetime warranty for the original owner.

Insulation and energy performance in Minnesota
Barrington's polyurethane-core slab insulates like any Masonite fiberglass door; any glass is where to be careful in Minnesota. Order Low-E argon glass on every lite, favor decorative or textured lites over full clear glass on north exposures, and install the complete Performance Door System.
Glass packages
- Clear glass upgradable to Low-E or Low-E argon
- Decorative glass with caming (antique black, platinum, brass) and beveled patterns
- Textured privacy glass options
- Matching sidelites and transoms
Frame and sash
Fiberglass facings over a polyurethane foam core (about five times the insulation of wood, per Masonite), square-edge construction, Performance Door System frame with sill, weatherstrip, and corner seals.
Ratings
Masonite lists ENERGY STAR certified exterior doors; certification depends on glass size and package, so ask for a certified Barrington configuration. Per-design U-factors are not published on the collection page.
What the install adds
On install day we set the unit on a sill pan, tape the frame to the housewrap, fill the jamb and head gaps with low-expansion foam, and seal the interior with backer rod and sealant so the air seal is continuous. Outside, a sealant joint at the brickmould keeps water out of the wall, and we shim and adjust the sill so the weatherstrip compresses evenly all the way around.
