Do You Need Expansion Gap For Vinyl. Most vinyl is 2mm - 6 mm thick which normally require 18 expansion gap. Do leave an expansion gap for click-lock vinyl.
The expanding laminate floor has no gap to allow for movement. Lumps and dips are hard to see with the naked eye. This includes walls permanent cabinets pipes etc.
For normal LVT you dont need expansion gap.
The instructions say to leave a 18 perimeter gap but do not say anything about an expansion gap at a certain maximum run length or between rooms. Im thinking you should have had expansion joints at the endbeginning of the narrow area s. Engineered floors do not require the expansion area solid products need due to the way they are constructed in cross ply layers similar to plywood. Though LVF itself does not change size.
