Insulating a tiny house roof.

If you recall from our tiny house exterior. It is the best insulation in the world barring vacuum insulated panels. Staple plastic or foam baffles to the roof sheathing near the eaves to keep the material away. What are some standard criteria for choosing tiny house insulation options.

Xps insulation in a tiny house xps boards are sheets of foam that are sold in various thicknesses. So the next and final step of the roofing build was installing the metal and eave trim. It fills in every crack and pocket sealing it completely. Expandable spray foam is a very popular way to insulate tiny homes.

It s paramount to check if a type of insulation can prevent moisture. The airflow from the soffits to the ridge vent keeps the roof cool and prevents ice dams and the material will block that flow. Spray foam is a great insulation to create an air barrier in any structure including a tiny home. Resists moisture that can lead to mold or mildew.

If space is more important than cost then aerogel will give you a 10 3r value per inch of thickness. For the same reason insulation shouldn t touch the roof s underside. These sheets are generally trimmed down to fit within the wall cavities and is a good diy option that is relatively easy to install not very expensive and still provides a high r value. You may not want to insulate your entire tiny house because of the expense but you can strategically insulate certain areas.

Spray foam is impermeable to water. It becomes ridged when dried and adds structural integrity. Thats a wrap post we had already installed the roof underlayment over the plywood sheets. Spray foam is especially subject to loss in r values and this can be greatly exacerbated by being in a thin 2 4 dimensional wall.

R value which is the capacity of material to withstand the heat flow is the first thing to. Resist heat value. But it actually can suffer from the same problems of 1 in this post.
