Use T-moulding as a bridge that covers the gap between two surfaces of the same height.
Where it is used
Between two rooms with the same flooring (e.g., tile to tile or laminate to laminate)
In doorways or transitions
To allow for floor expansion gaps (especially with laminate or vinyl floors)
Key features
Shape: Top is flat, bottom has a stem (like “T”) that fits into a groove
Purpose: Covers gaps and creates a smooth, clean finish
Materials: Wood, PVC, aluminum, or laminate
Height match: Works best when both floor surfaces are equal height
Example
If you install laminate flooring in your living room and bedroom, you use T-moulding at the doorway to join both floors neatly while allowing them to expand without damage.
