What insulation you should choose depends on climate, location, application and national building codes.

Our units are insulated with PU and/or glass wool sandwich panels. EPS is also available if you prefer a cheaper option. 

You can choose between thickness 50mm, 75mm and 100mm. The thicker the better but there's also a price difference and you might not need more than basic, lower cost thickness. It all comes down to climate and what you will use your container house for.
