laminate flooring in doorways

I will be installing Shaw laminate flooring over a concrete slab foundation. The instructions say use T molding in doorways less than 6 feet wide. Does this mean I need to use a T molding in all doorways? I have doorways that the laminate will continue through the doorway into adjoining rooms.I also have a 4 foot wide opening with out a door that leads from a hall into a living room. I would think the laminate floor would be stronger if it's continued through a door and remain interlocked rather than cutting it up into room sections and using T moulding. It will look better without the molding also. I have a picture but can't find anyway to upload it. The store we bought the flooring from gave us transition mouldings only. They said to use these in the areas/ doorways that meet up with different floor types. They told us they are universal. I asked about T mouldings and they did not give us any.Should I call Shaw direct and ask them?

 

When I laid my laminate thru our LR/front hallway off the front door, DR/continuing hallway leading to office and ending at a bathroom and into 2 closets, -All is continuous throughout the area...running from the 16x12' LR, hallways, 12x10' DR, 10x9' office...
I used 3-T moldings. 1 at the hall closet (coz the closet lam is perpendicular to the hall lam), at the office off the hallway, since the office lam runs NE..parallel to that window and perpendicular to the hall and at the bathroom, coz the bathroom is cork planks.
T moldings are 'kinda' universal in design..but not necessarily in material or color...along with its tack strip...where the T molding sets in place..
If they dont have it (or cant provide, which would seem odd) Im sure you could find some at the big box stores. Ive seen them at HD or Rona/Revy....
Good luck........

 

Each area of the installation, needs to float/move independently. If you choose to run it through the doorway, you could see separation later as the areas move differently.


If the lengths run through the doorway, it is stronger and resists separation, unlike the planks running across the doorway, with a seam edge right in the doorway, which will separate, eventually.

 

So I can get away with running the planks direction perpendicular to my 4 foot door opening without a transition piece?
And then my other room that joins of the hallway will have planks running parallel with the door opening width so I need a T molding in that doorway.

 

Correct, as long as you undercut the doorjamb trim molding to slide the flooring underneath, while maintaining the desired expansion gap.

 

Do I undercut the door jambs back to the stud and then cut the laminate to leave 1/4 " from the stud? Never mind-I found out. Thanks for all the help.
