Exterior Doors

EXTERIOR door panel construction

Solid Wood Exterior Door Panels:

Timbergate exterior raised door panels are hand-selected for consistency of grain, color, and appearance. Timbergate works to blend these natural wood characteristics for a final pleasing appearance. For the door panels that are 1 3/4" or 2 1/4” thickness, Timbergate face-to-face laminates three panels to create the desired panel thickness. These laminated panels are more stable than an individual solid piece of lumber – better doors through better design and engineering.

Exterior Doors with Applied Moulding:

The uniquely designed moulding used on our Timbergate exterior doors are designed to be used with any of the stile and rail profiles. This ability to choose from any of our standard profiles gives the customer the ability to create very distinctive looks at no up charge. Exterior entry doors have moulding applied to both sides.

Exterior Veneer Door Panels:

Timbergate exterior veneer door panels are unique. Our veneer panel doors use a high-density particleboard core similar to many other manufacturers. Most veneer door panels are constructed using a single sheet of wood veneer to cover the core material resulting in a panel that looks very generic. In Timbergate we cover our core material using veneer sheets constructed using many smaller strips of veneer called staves. The use of the smaller staves creates a veneer sheet that looks much closer to a true solid wood panel. The panels are readily available in all standard wood species.

Exterior Air Door Construction:

Timbergate uses a proven system of door construction called "Air-Door". Wood cells change in size due to changes in the natural environment based on moisture and humidity levels. This natural shrinking and swelling of wood is natural and to be expected. To
compensate and prepare for the "Physics" of wood, Timbergate uses an Air-Door suspension system of construction to allow for the door panels to float in air. Urethane gaskets are installed around the perimeter of the panel to hold the panels firmly in place while allowing for expansion and contraction. A wood spacer is used on the bottom of the panel instead of the urethane inserts. This eliminates the panel from settling.

Exterior Door Sizes:

Standard door height is 6’ 8”. Door heights of 7’ 0” and 8’ 0” are available. All doors come prefitted 3/16” under nominal widths and 1” under in height. Custom door sizes are available



Exterior Thick Wood Veneers:

Timbergate laminates, thick wood veneer to the Core Stock of the exterior door stiles and rails to form the final door frame components. Timbergate makes this thick veneer by slicing hand select solid lumber to achieve matching wood veneers. This process and the resulting veneer material are far superior in quality, thickness, and wear to typical wood veneer. The thick wood veneer starts as 110 thousands thick before final finish sanding.

Exterior Core Stock:

The stiles and rails of Timbergate exterior doors are made of "laminated" pieces of hand selected solid wood. The laminated pieces of wood form the foundation of a
solid door, which is designed for stability against warping, twisting, and cupping. These individual pieces of wood are finger jointed, set on edge and face glued for strength and stability.

All inside and outside edges are banded using solid wood. Frames are 4 3/4" wide top, 5 1/2” wide sides, and 7 1/4" wide bottom.

Note: Wood parts are treated with a wood preservative prior to assembly and finish.

Exterior Blind Mortise & Tenon Joints:

Timbergate uses the "time tested" method of mortise and tenon joints for construction of the Timbergate door frame. The Blind Mortise and Tenon joint offers more surface area for the application of construction adhesive to bond the door stiles and rails together. The time-tested method of mortise and tenon construction is worth the extra time during construction.


exterior jamb CONSTRUCTION

Exterior Solid Wood Jambs:

Timbergate uses select and better solid wood for the exterior door jamb. Solid wood jambs are standard with all Timbergate doors. Solid wood jambs are constructed using wood screws versus the industry standard of pins and staples. The use of wood screws allows for the disassembly of the jamb if desired for field adjustment. All pre-hung Timbergate exterior doors include a 4 9/16” solid wood jamb or clad jamb, and are shipped with a 1 3/8”?adjustable sill on the bottom of the jamb. Other jamb sizes (4 13/16”,5 1/4”, 6 9/16, and 6 13/16”) are available. Custom jamb sizes other than those listed above are available.

Exterior Clad Jambs:

Timbergate exterior clad jamb consists of white pine finger joint with raw wood (matching the wood species of the door) rabbet standard, with end treatment on bottom at sill prep on end grain. Roll form aluminum hot glued to exterior face of frame. Vinyl nailing fin included but not applied. Standard colors: White, Sand, Bronze, Green, Almond, and Terratone.

Exterior Continuous Sills:

Timbergate Continuous Sills are manufactured with an extruded aluminum threshold supported by a rot-resistant, all composite substrate. These adjustable sills feature an overlap cap with an integrated seal, covered adjustment screws, and High Dam Design. Available finishes are Mill (standard), Brushed Nickel, Brass, and Bronze. Simulated walnut finish cap and nosing standard.

Brick Mould:

Available in all wood species.

Clad Brick Mould:

Roll Form Aluminum. Available in our standard Clad Jamb Colors

Door Sweep:

Double Bulb. Replaceable


Qlon .650 Reach Bronze Weatherstrip

exterior Finish

Exterior doors are machine-sanded followed by a thorough hand-sanding to prepare the wood surface for treatment and finishing. A penetrating wood preservative is then applied. A penetrating stain is then applied and hand wiped. All door panels are pre-stained before door construction and assembly to diminish the appearance of an unfinished line during the natural expansion and contraction of the solid wood components. A dual component polyurethane sealer coat is sprayed on and oven cured. After curing, the sealer coat is sanded and the door is prepared for the topcoat. The topcoat is a dual component polyurethane formulated with crystal clarity providing superior surface resistance and appearance.

Doors are assembled and machine-sanded to flush the joints and create a smooth, uniform surface. *Timbergate highly recommends additional hand sanding at the jobsite before finishing. Unfinished doors will follow a stain grade wood selection which will have variations in color, grain, and texture. These variations occur naturally. Darker stains tend to reduce the visibility of the variations, light stains and natural finishes tend to enhance the variations.
