2. Stile & Rail Doors Construction Quality & Design Options

3. Learning Objectives: Identify the characteristics in a true stile and rail door. To recognize the construction differences that go into a stile and rail door. Recognize the increased design options available with custom stile and rail doors.

4. Key Terms: Stile – Vertical Outside members of the door Rail – Top and Bottom members of the door Mullions – Members between panels – Vertical or Horizontal – often called intermediate stile or rail. Panel – products that fill the frame of the stile, rail and mullions Muntins/Bars – Members between glass panels. Usually smaller in width – also called Mullion Profile – The decorative cut used on the sticking and all panel edges. Joinery – construction method used connect stile and rails.

5. Stile & Rail Construction Detail -Most stile and rail doors consist of a core material with solid wood sticking for the inside and outside edge, and a solid wood veneer glued to the face of the stile and rail.

6. Stile & Rail Construction Detail Common Core Materials -Lumber core – Low density staved. Usually pine, labeled Solid Wood -Composite Core – Medium Density Particle Board -Medium Density Fiberboard core (MDF) -Two piece laminated – usually solid wood or MDF.

7. Stile & Rail Construction Detail Lumber core – Low density staved. -Pine lumber core engineered for stability -Cut into shorter staves -Finger-jointed then glued together -Sticking is solid wood – same as wood specie for veneer.

8. Stile & Rail Construction Detail Composite Core - Medium Density Particleboard -Wood particles of various sizes that are bonded together with a synthetic resin or binder under heat and pressure. MDF – Medium Density Fiberboard. -Wood particles reduced to fibers in a moderate pressure hot press, combined with a resin and bonded together under heat and pressure. - Slightly better visual edge quality than composite core. - Smoother than composite core.

9. Stile & Rail Construction Detail Common Core Materials -Two piece laminated -Either MDF or Solid Wood faced glued to achieve thickness. -Two piece solid wood is designed to add stability. -Two piece MDF is a manufacturing choice but has no impact on stability.

10. Stile & Rail Construction Detail Joinery Options -Cope & Sticking with Dowel -Mortise & Tenon Joint -Cope & Sticking – detail from Trustile

11. Inside the Stile & Rail Lock Rail – Middle rail, usually larger for lock set and machining. Mullions – inside sections to hold panels Panels - Raised Panel - Flat Panel

12. Inside the Stile & Rail Raised Panels Nominal ¾ inch or 1 1/8 th inch Most common are: - Solid Wood staved panels - Rim raised veneer - Pressed Particle Board/Veneer

13. Inside the Stile & Rail Solid Wood staved panels Natural look of solid wood More detail in the profile Staves control warping, bending, cupping Hand sorting staves controls color variation. Sanding for smooth finish More lines from staved panels

14. Inside the Stile & Rail Pressed Particle Board/Veneer Wider veneers have less color variation No issues with warping or cupping Doesnt expand/contract as dramatically as solid wood due to shifts in humidity Panel profile exhibits less detail

15. Rim Raised Panel Panel is fabricated with a Particle Board core picture framed with solid wood sticking and veneered on both faces Wider veneers have less color variation No issues with warping or cupping Minimal expansion & contraction Good panel profile detail capability

16. Inside the Stile & Rail Flat (Recessed) Panels -Usually 3/8, ½, or ¾ composite core or MDF core plywood, or MDF for painting

17. Inside the Stile & Rail Panel Retention -Doors are engineered to allow panel(s) to expand or contract in reaction to changes in humidity -Flexible cushions in the panel groove allow panels to float allowing expansion and contraction yet secure panel from shifting or settling.

18. Inside the Stile & Rail French Doors Key Terms: - Mutins – Center member (a thin mullion) - Lites – a pane of glass - Glass Stop molding – applied molding piece that holds in the glass. - True Divided lite – when each lite is individual pane of glass - Compression fit – built into the door and secured within the panel groove secured with an applied glass stop molding on one side.

19. Custom Design Options Stile & rail doors open up the design options to any panel configuration that will work structurally inside the stile and rail. Including wood raised or flat panel and glass lite combinations Solid wood core/veneer engineering allows for numerous wood species. Solid wood and MDF allow numerous options for profiles and applied moldings. Pre-finishing allows interior doors to match all solid woodwork throughout the home or office.

20. Custom Design Options Panel Configurations

21. Custom Design Options Wood Species More standard: Popular Design Choice - Cherry - Mahogany - Maple - Character Cherry/Oak - Poplar - Brazilian Cherry - Fir - Walnut - Alder – Select/Knotty - Red Oak

22. Custom Design Options Profile and Applied Moldings The profile allows for additional design touches to make the door unique. Applied Moldings are separate molding piece applied near or over the sticking profiles for additional decorative design.

23. Custom Design Options Profile and Applied Moldings Profile options Applied Molding Options

24. Custom Design Options Pre-Finished Doors – differences Provides factory quality finish Allows for more cabinet quality design options with distressing, glazes, etc. Allows for custom match to other interior woods for new construction or remodel Time and cost savings in the field.

25. Stile & Rail Doors Summary of Learning Objectives: -Identify stile and rail door? -Stile and rail in separate pieces joined together -Interior panel configuration – many custom options -Construction differences -Joinery options to improved quality -Veneer applied over core material to engineer quality -Solid wood allows for sanding, and profiles for improved quality. -Design options -Custom panel configuations -Unique species -Profile and finish design options to work with style of project.
