Shipping Containers

Why InSoFast for containers?

There are many ways to insulate and frame in a shipping container. We think we are one of the best methods available today. We offer our method and thoughts on the correct way to insulate a shipping container above with our start here button.  We make it look easy because we are skill professionals and our panels are not always the best solution for every project. It is for you to decide if one of our system is the right one for you. Your first challenge will be controlling the dew point where condensation can occur.

The first challenge.

There can be a significant amount of moisture produced within a shipping container depending on the designed application. A container converted into a residential dwelling, with its inherent air-tight building envelope, has special design consideration for humidity and surface condensation. In traditional home construction, water vapor is controlled by various means, like air leakage through the building’s envelope. Containers cannot rely on air leakage to control humidity; unlike frame construction.

InSoFast is a high performance injection molded, closed cell, insulation panel that that helps controls cold surface condensation.

Energy Codes

The Next Challenge

Building codes and R-Values requirements are designed for traditional framed construction. Shipping container are not traditional. While codes are well-intentioned, they don’t consider the airtight and diminutive size of a shipping container. Local townships hold container construction to a higher standard, because it is different. InSoFast has information available to help you navigate your local requirements.

Space Not the Final Frontier

It’s easy to increase your R-Value beyond code minimums while maintaining the engineered benefits and maximum interior space with InSoFast panels. InSoFast lets you balance high performance wall insulation against the need for valuable interior LIVING space. For more information about "Space vs. R-Value" go to our InSoFast PLUS page.

When environmental disasters force cities, islands and countries to declare that there is a “ basic shelter and low income housing crisis” up-cycling or recycling shipping containers is a sensible solution. Reusing intermodal containers are a responsible way to respect the planet and people. InSoFast is the easy way to turn cold, corrugated steel containers into cozy and safe homes. InSoFast is so easy that professional builders and volunteers can work together to construct housing for homeless and other at-risk residents.
