Door Specifications and Technical Information

All of our standard overhead doors are constructed of Clear Western Red Cedar over Doug Fir frames and trimmed with Cedar of 3/4" thickness, Overhead doors are insulated with a minimum 1" foil faced foam and backed with super plywood, marine grade plywood glued and screwed from the trim through to the frame with stainless fasteners and polyurethane glue. Overhead door thickness ranges from 2 3/4" to 3 1/2". Doors to be painted leave our shop primed on 6 exterior surfaces (see below). We offer other types of wood like Cypress, Honduran Mahogany and Douglas Fir for exterior materials.

Standard Door Products

The 3 door models above are standard in widths of 9 feet and heights of 7-8'. Other dimensions are available upon request and variations on these themes may be made very simply. For example, cross or half bucks may be added or deleted (like the Barn design) and number of windows may be changed based on height or number of door sections (this may be a requirement). Cedar panels may also be constructed in a herringbone design instead of the vertical designs show above.

Materials - Wood

• Western Red Cedar: We use only A and better on garage door exteriors for both vertical boards, overlay trim and window components. Western Red Cedar is a dimensionally stable wood that resists shrinkage, warping, and insects. It is rot resistant (not rot-proof) and looks great with clear or semi-transparent oil stains and high quality finish paints (see below).
• Douglas Fir: We prefer Douglas Fir for door frames in full lengths (no finger joints). It is a light and dimensionally stable wood with very straight grain and is ideal for outdoor applications and weather. We do not use pine framing which is not as stable, straight grained and resistant to rot and insects.
• Mahogany:We use varying grades of mahogany based on the use, design and application of the door and the size of the overall opening. Mahogany is also ideal for outdoor applications and longevity. It is an expensive, highly stable wood, but is well worth the investment in door construction.
• Plywood:All overhead and sliding (and some swinging doors) are backed with 1/4" super plywood or marine grade plywood which enhances the structure and provides a backer plate for door hardware. Customers may request other back materials such as hemlock (for barns) or cedar as a special order or an open back with traditional internal cross-bucking.

Materials - Glues, Fasteners, Primers, Stains, and Paint

• Glue & Fasteners: We use polyurethane adhesives which have a high dry and wet strength, and resistance to water and damp atmosphere*. Fasteners are all stainless and are used from the trim through to the framing in combination of screws and nails. No galvanized fasteners are used.

• Clear stains: Upon request, we will clear-coat cedar doors with a Water Repellant Stain (WRP). WRP s help protect exterior woods from degradation and mildew attack. Both painted and clear stained doors require at least semi-annual maintenance. Instructions must be followed to maintain the warranty.

Materials - Glass

Standard doors come with true divided light windows and 1/8" high strength glass or optional insulated glass sections or insulated type up to 1". Other glass materials are also available (antique, frosted etc.)
