I am in the process of renovating a 5-window minibus into a tiny home on wheels and one of my first projects was the floor. I am doing this on a very strict, small budget and happen to have been given a stack of the "puzzle mat" packs - the kind that link together and that holds the mat pieces together quite well, but...I am using these 24 x 24" black puzzle mats as my floor insulation and they are really wonderful for cutting to fit the interior of the bus and with the edge pieces they fit so well, I'm really pleased with how they are covering the floor of the bus. BUT, as the insulation, I want to ensure they stay together and to that end, I used this mat tape to hold the pieces together once I had each section completed. The actual sub-flooring of 1/4" OSB board was laid over these mats and attached to furring strips attached along the sides and back of the bus as well as across the width of the bus at intervals. I had some really pretty faux flooring (peel and stick almost like contact paper, really) which I laid down over the OSB and then used a couple of coats of polyurethane to make the peel and stick flooring durable. That was how I created a floor on a budget and this tape made the insulating mats a good, strong underflooring base for the subfloor!
