I am planning to install Pergo laminate floor. When I look up on installation guide, it recommends to use transition molding for doorways less than 4 ft or room larger than 40 ft.
My question is that is it necessary to really use transition molding on each doorway ?
My house got standard size room doors and they are all less than 4 ft. My master room has 3 doors. I don't want to install transition molding everywhere. Can I leave more expansion gap around the perimeter to avoid transition molding? They claim to void the warranty though if I don't follow the installation guide.
