Solid Hardwood, Engineered and Laminate Flooring - laminate

hello all
i am installing new laminate and in my doorways that have no door i need to know if there is a rule of thumb about where to break the laminate for the transition between the two rooms. one is tile and the other is the laminate im installing.
Thanks!

I would say in the middle of the doorway that has no door. Will have to get a transition strip to fit and I would get that before I did the laminate so I would know what kind and where you need to start the laminate so that it will be covered by the strip. The height of each floor determines what kind of transition strip you will need. Go look at them at Lowe's or Home Depot.

thanks for the opinion. that is where i figured to put it but didnt know if there was this unwritten rule. i think if a door is present you put the transition strip under the door?
thanks!

Yes, if there's a door, you want to terminate two dissimilar materials directly under the center of the door. With the door closed, you don't want to see tile on the laminate side or laminate on the tile side. For a pass through, with no door, the center of the pass through is the correct place to terminate it. This provides a balanced look. If you do it some other way and do so not understanding the correct way to do it, it'll bother you every time you look at it but you won't know why. As to a termination strip, If the tile is installed on a backer board, use the termination piece designed to go from laminate to nothing or vinyl, but turn it around and use it backwards. Let the part designed to lip over the laminate actually lip over the tile and let the part designed to lip over the vinyl actually lip over the laminate. This piece will be up too hight to actually reach the floor so you'll have to put a shim under it to raise it up. A scrap of the laminate should be just about the right height. If the tile is installed straight to a concrete slab, use a "T" mold because the two surfaces should be very close to the same height. You'll only need about an 1/8th inch gap from the tile to the termination piece, but you'll still need the 1/4 inch gap on the laminate side.
