I started working on the upstairs loft bedroom of my tiny house on wheels. First I had to finish the insulation upstairs before I could begin with the radiant foil.
I had to put up a nailer near the ceiling of my tiny house loft bedroom. This was a simple 2x4 nailed to the ceiling.
Next I stuff insulation in the rest of the holes I never finished before.
When all the spaces were filled I put in some 1x2 furring strips to keep the radiant foil away from the wall of the tiny house. This gives me a 3/4 inch gap between the insulation and radiant foil. Radiant foil need at least a 3/4 inch space on both sides in order to keep out summer heat and keep in the winter heat.
So far in this video I managed to get one wall covered with the radiant foil. The second part of the job is on the way soon.
