PRODUCT SPECIFICATIONS FOR SAWMILL CREEK OVERHEAD GARAGE DOORS

Materials and Construction

Flush Door Core

The “flush door” core is 1 inch thick pine with 1/8 inch hardboard applied to both sides of the frame with an exterior grade adhesive.

• The top and bottom rails of the door are 5-1/2 inches wide.
• The stiles are 3-1/2 inches wide.
• There is 1 inch of insulation between the hardboard faces.

Exterior Woods

All face material exterior wood applied to the door is Western Red Cedar.

All of the exterior wood components of the door are applied with polyurethane adhesive and staples. The door may have a mixture of light and dark grains and may have an occasional small knot that is typically inherent of Western Red Cedar. The natural characteristics of cedar make it a preferred material for exterior applications. Western Red Cedar contains natural oils that act as preservatives to help the wood resist insect attack and decay.

Properly finished and maintained, Western Red Cedar will stand up to the elements for many years.

Standard Face Materials

Millwork used on the door face is 4 inch V-Groove, 4 inch Bead-Board, or Flat paint able surface. The 4 inch V-Groove or 4 inch Bead-Board are true tongue and groove materials. They are not sheets of plywood made to look like tongue and groove.

4" V-Groove


4" Bead Board


The 4-inch face material will have a repeat every 3 inches, meaning the visual portion of the board as it lies on the door is 3 inches wide.

Design Elements

Trim boards can be added to create a variety of design elements of the door. These are not considered structural elements, they are meant to define specific looks.

Simulated Posts

Simulated Center Posts can be used on 16 ft and 18 ft doors to give the illusion of two doors. The simulated post is 7-1/2 inches wide. The top of the post is beveled and set down 3 inches from the top of the door to allow for clearances when the door is opening and closing.



Perimeter Board / Trim Boards

Perimeter boards are boards applied to the outer edge of the door. Except for the bottom board, the perimeter boards are 5-3/8 inches wide. The bottom board is 5-1/2 inches wide. The trim boards are 3-1/2 inches wide. Trim boards include horizontal trim boards as pictured below, half bucks, cross bucks and battens. Battens under window sections are 3-1/2 inches wide.

The split look is made up of two boards 3-1/2 inch wide with a saw kerf 1/4 inch wide x 1/4 inch deep at the point the two boards meet.



Door Interior

The interior side of the door is flush hardboard. The interior of the door is factory primed. The cedar in the window will be bare without a finish applied to it. The door interior is primed and is a paint only finish. Staining the interior is not an option except for the window components.

Glass Options

The available glass options are 1/8 inch clear double strength glass, or 1/2 inch thick insulated glass.

• The 1/8 inch clear double strength glass is a single pane of glass. Double strength refers to the tensile strength of the glass. It is not safety glass and is not a replacement for tempered glass. It can be cut by most hardware stores and any glass company if a replacement is needed.

• Insulated glass is two panes of 1/8 inch clear double strength glass that uses a 1/4 inch aluminum spacer between the two lites. Adhesive sealant is used to hold the pieces together.

Window Grids and Window Sub-Frames

Window grids or muntins are made from western red cedar. They are applied to the exterior of the door. They can be stained or painted to match the rest of the door. Window grids are 1 inch wide x 1/2 inch thick. The window grids are not attached to the glass so if the glass is broken, only the glass need to be replaced, not the window grids. The grids are half-lapped joints at intersecting grids. The grid pattern is available in a variety of options.



The window sub-frames shown above are made from Western Red Cedar. The top and bottom rails of the sub-frame are screwed into place and fastened to the rails of the door. Doors with curved top trim will use square lites. The curved trim on the exterior is a facade. On the door interior, a rectangular lite will be visible as will the backside of the curved facade. If it is desired to finish the back side of the curved facade to match the interior of the door, the window will need to be removed.

Section Height and Shiplap

The top and bottom section on all doors is 30 inches tall. Section heights do NOT all have to be identical

• A 7 ft tall door will have three sections 
  Section 1 (Bottom) is 30" tall 
  Section 2 (Middle) is 24" tall 
  Section 3 (Top) s is 30" tall 
• An 8 ft door will have four sections 
  Section 1 is 30" tall 
  Section 2 is 18" tall 
  Section 3 is 18" tall 
  Section 4 is 30" tall 
• A 9 ft door will have four sections 
  Section 1 is 30" tall 
  Section 2 is 24" tall 
  Section 3 is 24" tall 
  Section 4 is 30" tall 

The meeting rail of each section has a 1/4 inch shiplap joint to act as a weather stop. There is no weather seal between the sections.


Thermal Conductivity

Sawmill Creek™ Doors have not yet been tested for thermal conductivity so a thermal rating has not been established. They are estimated to have an "R factor" between 5 and 7.

Moisture Control

Moisture is the number one element that can destroy any wood product. We incorporate several details into the construction of each door to help prevent moisture damage.

• An oversized bottom trim board restricts water from running through the V-Grooves and getting trapped under the bottom trim board.



Weather Seals

• A bottom seal made of EPDM rubber is supplied with a mounting track to be mounted on the bottom of each door to prevent the door section from coming in direct contact with the floor.

• A cedar doorstop that contains a vinyl weather seal is supplied with each door. It is fastened to the door jamb with nails or screws. The seal is available in white, dark brown, gray or tan.

Door Opening Size

In order for the door to fit properly in the opening the opening must be of the appropriate size. The door opening should be equal to the size of the door. The perimeter boards are larger than the other trim boards so when the stop is applied a reveal similar to the width of the other trim boards on the door is left.

The drawing below shows a door properly sized for the opening. The opening dimensions to the finished jambs should be the same size as the door.



If the opening is smaller than the door, the reveal of the perimeter boards will look out of place as compared to the other features of the door. The drawing below represents a door placed in an opening that is several inches smaller than the door.



If the floor is uneven and the door requires trimming to fit, a maximum of 1/2 inch can be removed from the bottom of the door. Removing more than 1/2 inch can seriously affect the structural integrity of the door.
