OrePac Interior Door Collection

OrePac’s interior door collection centers on genuine knotty alder and pine options with solid core construction. The lineup delivers measurable advantages over hollow core alternatives — better sound dampening and a weightier feel that contractors notice immediately when hanging these doors.

Solid Core Construction and Model Variations

The engineered stiles and rails with solid finger-jointed wood core minimize warping and seasonal movement — a critical feature for Montana’s humidity swings between winter heating and summer conditions. Every door ships at 1-3/8 inches thickness with 1/8 inch (3.2 mm) veneer over that solid core.

The core model lineup breaks down into distinct variations:

Model	Panel Design	Key Difference
82	2-panel square top, raised panel style	Standard raised panel with ovolo (rounded) sticking profile
82V	Same as 82	Includes V-groove detail on the raised panels for a more pronounced rustic/plank look
82A	2-panel arch top	Features an arch-top panel design instead of the square top
782	2-panel square top	Flat-panel (shaker) version offering a cleaner, more modern profile

Standard widths run 18”, 24”, 28”, 30”, 32”, and 36” with heights at 80” (6/8) and 96” (8/0). That covers everything from narrow closet doors to full-width office entries.

Material Options and Quality Considerations

Knotty alder leads the lineup with natural knots and grain patterns for a rustic look. Douglas fir, knotty pine, and primed MDF alternatives hit different price points — the MDF option ships paint-ready for customers who want to skip the staining process entirely.

Every door comes factory sanded but unfinished. That’s not laziness — it’s practical. Doors must be properly finished and sealed on all six sides immediately after delivery and acclimated to the installation environment prior to hanging. Skip this step and the warranty disappears.

Real-world performance shows approximately 4.5 out of 5 stars with contractors praising the heavy, solid feel and high-quality wood texture. Natural knots take stain very well, though some doors arrive with too many or too few knots per door — typical variability in natural wood products.

Warranty Coverage and Installation Requirements

The 5-year limited warranty covers manufacturing defects in materials and workmanship but comes with strict requirements. Coverage applies to the original homeowner only — it’s non-transferable. Natural variations in color/texture, improper storage damage, and normal wear fall outside warranty coverage.

Installation demands precision:

• Allow 48-72 hours acclimation to site humidity before finishing
• Use 3 hinges for 80” doors and 4 hinges for 96” doors
• All 6 surfaces must be sealed with compatible primer/stain and topcoat
• Limited trimming allowed — up to 1/2” on bottom and 1/8” on sides

Hardware compatibility covers standard interior locksets with 2-3/8” or 2-3/4” backset. Doors fit standard interior door jambs in knotty alder, pine, or primed MDF.

Frequently Asked Questions

What makes OrePac’s solid core doors worth the premium over hollow core?

Solid finger-jointed wood core provides better sound dampening — valuable between bedrooms and bathrooms. The engineered stiles and rails minimize warping and seasonal movement compared to solid slab doors, while delivering that heavy, solid feel hollow cores can’t match.

How do the model variations differ beyond panel design?

Model 82V includes V-groove detail on the panels for a more pronounced rustic look. Model 82A features arch-top panels instead of square. Model 782 offers flat panels for a cleaner, shaker-style profile. The core construction remains identical across models.

What’s required to maintain the warranty?

Seal all six sides immediately after delivery with compatible primer/stain and topcoat. Acclimate doors to installation environment for 48-72 hours before hanging. Remember the warranty only covers the original homeowner.

Can these doors be trimmed to fit?

Limited trimming is allowed — up to 1/2” on bottom and 1/8” on sides to maintain structural integrity. Exceed these limits and you’ll compromise the engineered core structure.
