Is it necessary to place T-transition expansions or breaks in floating floors?



Is it necessary to place T-molding transitions and expansion breaks in floating floors?

Yes when directed by the manufacturer T-molding transitions and expansion breaks must be used. The reasons manufacturers recommend expansion breaks and doorway transitions in floating floors is three-fold. Humidity, Weight and Span Limitations.

When the indoor humidity climbs over 55% floor boards tend to swell or expand, this is normal. Under certain conditions when high humidity is sustained coupled with the weight of furniture and/or placement within a room, the center of the floor area could actually buckle or lift off the floor -without a planned center expansion. 

Some floating floors like bamboo are also heavy and T-transition expansions reduce the likelihood of buckling due to weight and pinch-points around walls and doorways.

 In addition, most floating floors like bamboo and laminates have span limitations. This means a product may not exceed predetermine span of feet in either length or width. In an effort to bypass span or center expansion requirements some installers have doubled the outside perimeter expansion space to a full ", however, installations outside the recommendations are viewed as experimental and can lead to installation failure.
