If you are considering building a tiny house then one thing on your checklist is the insulation of your tiny house. Many people decide on tiny house living, as it is a way to reduce the cost of living. Not only the cost of living but will also reduce their carbon footprint which is becoming increasingly important these days. They are even able to be easily built to take advantage of being “off the grid” using solar panels and batteries because of the reduced need for power.
You expect your tiny house to be cozy and this is the reason why tiny house insulation is important. They are more susceptible to exposure due to their tiny size. Things like wind shear strips the cocoon envelope from around the house which enhances the transfer of cold into the interior.
So what is the best for tiny house insulation.
It is during the building stage when it is best for applying tiny house insulation and the easiest way to do this is with spray foam. Why? Because spray foam provides the best barrier to air, moisture, heat and cold transfer. This is even more important if building a tiny house using a shipping container because of the susceptibility of metal to form condensation.
There are two types of spray foam used in tiny house insulation, open cell and closed cell, So what’s the difference? With open cell the cells are not completely closed and depend on the open end adhering to the next cell. With closed cell they are closed like a bubble. Two other factors are price and thickness required to reach a certain “R” value. Open cell foam has a “R” value of around 3.7 per inch. Closed cell foam has a “R” value of 7 per inch. Closed cell is more expensive than open cell.
So which should you use?
In most cases open cell is fine depending on the environment the tiny house is being located. In other environments closed cell is preferably but is highly recommended for tiny houses being constructed from a shipping container in any environment.

Want a snug comfortable tiny house? How much of tiny home should you insulate? All of it if possible but a minimum should be the walls and roof. For pure comfort you may want to spray under the floor as well. Well being a tiny house it’s not like having the cost of a 30 square home.
One thing to remember a well sealed tiny home will not only let you live in comfort but will pay dividends on energy bill savings. In all cases you should consult with one of our experienced and qualified technicians on the best way for tiny house insulation.
