Roammates – The Lieutenant’s Conversion – Vol.5

After hours, days and weeks working with plywood, we weren’t going to let some extruded polystyrene stop us!
Here we are now, starting to work on the floor, and knowing that soon all the metal parts will be covered is a great feeling!

After some time discussing our options, we decided to use polystyrene and plywood. Easier, cheaper, and it gets the job done!

FLOOR INSULATION

Extruded polystyrene is not only a good phonic insulating material, it is also a great thermal one, even with thin layers. Amazing news, isn’t it? In addition, it is super light as well, easy to handle, to cut and install! The edges are even made to interlink. What more could you possibly want?!

We got 4-centimeter thick (approx. 2 inches) panels, which wouldn’t waste too much height in the living space but would still allow for us to bury our electrical wires in them.

We started in the front, where we have the most space, in order to be able to use a couple of panels without cutting them, then created a sort of jigsaw puzzle, making sure we numbered each bit so we could find its place when we were going to glue it to the metal.

In the video, you can see Clémence sticking the panels with a glue gun and special polystyrene glue (which won’t deteriorate the panels). Glue may not even be necessary, as there will be plenty on top of the floor to hold the whole thing together! For the finishing touch, you might want to protect the sides/edges of your flooring with something rigid.

INTERIOR PLYWOOD

Obviously, you can’t leave your polystyrene like this.
We picked some 5-mm plywood, hard enough to support the furniture and our weight. Not as pretty as the poplar wood we used for the wall, which doesn’t really matter since we’ll be putting carpet on top of it. Its purpose is only to provide a hard surface and protect the insulation layer.

Nothing too complicated here, a bit of cutting and sanding, make sure all the panels fit together. Make sure you make holes for your electrical wires if needed, but besides that it is pretty straightforward…
And then, when you are ready, pick up your best glue gun and get going! Let the glue dry for at least 24 hours, with some weight on the floor, and that’s it!

Please feel free to comment and let us know how you did your floor, or how you would have done it, or how awesome you think we are! Or just to ask a question!
