Carpet - Threshold and Transition Question

Choosing what type of transition or threshold that connects hardwood at carpeted areas largely depends on what type of installation is being done. Each and every installer is different, with skill and pride in their workmanship also being a difference. In general the average installer will use manufactured trim moldings.
 
• Floating Floors -Overlap or baby threshold
• Glued or nailed- One sided reducer

Better  installers will often choose a more eye appealing approach in dealing with transitions from hardwood to carpet, but it does depend on the type of installation being done. For solid and glued installations that are fastened to the subfloor header boards provide a more professional and clean appearance.

How Are They Installed?

Wood Subfloors- Most installers prefer avoiding nails and use glue (Liquid Nail or equivalent) with transition moldings. However at times a few nails may become necessary at times to hold the transition in place before the adhesive sets.

Concrete Subfloors- Liquid Nail or similar used in conjunction with blue painters tape to keep the moldings (picture below) in place before the glue grabs or sets.

One Sided Reducer- Also called a reducer, tapers down from the height of the hardwood to a lower vertical surface. It's often used for transitioning from hardwood to vinyl, terrazzo, or concrete, but is used now and then for carpet, depending on the carpet height.
   
Baby Threshold, Overlap Reducer, or End Cap- Used with floating floors because transitions cannot be attached to the floating floor itself. With more inexperienced installers or rush home builders these transitions are also used with flooring attached attached to the subfloor.
   
Header Board- Used with same material for flooring. Piece is cut to fit in the door opening or at carpeted area. Carpet is then stretched and tucked at header board. Often used when carpeting is higher than the flooring. Provides a more professional appearance.
   
Header Board Beveled- For unfinished or sanded in place flooring these transitions are made on the jobsite then sanded and finished. There are unfinished reducers for this application in solid 3/4" products, but are rarely used with unfinished floors.
