30' 2"? I don't think you need a T-molding.
For a floating installation;
Floating floor expansion Perimeter expansion space for room areas 30’x30’ and under is ½”. Room areas exceeding 30’x30’ expansion space is ¾”
No spans or connected flooring can be greater than 40’ in any direction without an expansion break. A connected area is defined as all room areas using the same flooring, connected. Expansion breaks can be placed in doorways, between rooms or hallways.
Expansion breaks can be hidden using T- type expansion moldings. Please contact me directly and I would be glad to answer any of your installation questions.
