Prep & other specifications:

  • Select either No Hinge or Lock Prep or Standard Hinge & Lock Prep:
    • No Hinge or Lock Prep: allows for lock placement as desired and hinge side edge unfinished and can be mortised for hinge placements as needed
    • PEASE Standard Hinge & Lock Prep 79" tall doors:
      • Hinge mortise (cut out) 6.5" from top of door to top of first hinge, 37.5" to top of second hinge, 68.5" to top of bottom hinge
      • Tubular lock prep comes for 2 3/8" backset lockset and means the door will have two 2.125" holes 5.5" apart, each hole 2 3/8" from the center of the hole to the edge of the door, with the top hole center 40.375" from the top edge of the door
    • PEASE Standard Hinge & Lock Prep 83" tall doors:
      • Hinge mortise (cut out) 6.5" from top of door to top of first hinge, 39.5" to top of second hinge, 72.5" to top of bottom hinge
      • Tubular lock prep comes for 2 3/8" backset lockset and means the door will have two 2.125" holes 5.5" apart, each hole 2 3/8" from the center of the hole to the edge of the door, with the top hole center 44.375" from the top edge of the door

  • Trimming: Can field trim up to 0.5 inches off bottom, then we recommend sealing thoroughly with caulking and capping with a U-style doorsweep. Sides and top are not trimmable. For factory trimming (~1 to 5 inches of height), please contact us. This is a replacement for most entry doors (front, kitchen, side, garage/man door, etc.) and can also often be trimmed and used as a replacement for patio doors which are typically shorter in height.
Construction & Materials

Premium Build Construction: Stronger Than Standard Doors

Our fiberglass entry doors are built using a Premium Build configuration featuring full-length 4" LVL (laminated veneer lumber) side stiles on both sides of the door. These engineered stiles run the full height of the slab, delivering a stronger, heavier, more rigid door than the simplified constructions used in most entry-level fiberglass doors sold at big box stores.

The fiberglass skins resist warping, rotting, denting, and rusting, while a high-density polyurethane foam core provides insulation and contributes to the door's structural integrity. Composite top and bottom rails help resist moisture intrusion and long-term deterioration. Homeowners and contractors will notice the difference in weight and rigidity the moment they handle the door, a clear indicator of the build quality engineered into every slab.

Reversible Lock Prep: No Wrong Side

Because the 4" LVL stiles run full-length on both sides of the door, hardware can be bored into either stile with equal structural support. This eliminates one of the most common installation errors, boring hardware on the wrong side, and gives buyers full flexibility on door handing. DIY homeowners get peace of mind during installation, and contractors avoid costly rework on the jobsite.

Engineered for Everyday Performance

Together, the full-length LVL stiles, insulated foam core, and moisture-resistant composite rails create a door built to perform reliably in demanding exterior environments. The result is a door that installs with confidence and delivers dependable performance year after year.
Finishing

Surface Texture and Recommended Finish for Smooth Fiberglass Doors

This door features a Satin Smooth (white) surface with a fine linear texture and subtle vertical lines, similar to a woven linen or brushed fabric. This micro-texture provides built-in surface tooth that helps primer and paint adhere without the need for heavy sanding, reduces the visibility of brush marks and roller lines, and helps prevent runs and drips on vertical surfaces.

Before finishing, clean all door surfaces to remove dust, oils, and handling residue, then allow the surface to fully dry. For best results, we recommend using a high-quality bonding primer such as Sherwin-Williams Extreme Bond Primer, followed by a premium exterior-grade acrylic latex paint.

All six sides of the door must be finished, including the front, back, top, bottom, and both edges, to properly protect the door and maintain warranty coverage. When selecting paint colors, lighter to medium shades are typically recommended for doors exposed to direct sunlight, as very dark colors can increase surface temperatures and reduce long-term finish performance.

Fiberglass doors are shipped unfinished or factory-primed depending on selected options. Finishing should be completed promptly after delivery and before prolonged exposure to weather.
Installation

Installation Readiness for Fiberglass Door Slabs

Fiberglass door slabs are designed for installation into existing door frames or for assembly into new prehung units. Before installation, verify that the slab dimensions (width, height, and thickness) match the existing slab for replacements, or the jamb set for new assemblies.

When replacing an existing slab, the original door can often be used as a template. Align the existing door on top of the new slab to transfer hinge locations and hardware positions for accurate placement.

Minor trimming of fiberglass door slabs may be possible depending on the door construction, but allowable trimming limits should always be verified before cutting. Excessive trimming may affect performance or warranty coverage.

Fiberglass door slabs are heavy and should be handled by two or more people during installation. Always support the door evenly to prevent damage to corners or edges.

Complete all recommended finishing steps promptly after installation to protect the door surface and maintain long-term performance.
