Building Accessory Dwelling Units (ADUs) with Insulspan® SIPs

Plus Space™ ADUs by Insulspan meld a highly energy efficient structural shell with a completely configurable interior space to create the next wave of auxiliary dwelling units. One in which the ADU you build will meet all your needs—whatever they may be.

Plus Space™ ADUs are built using the Insulspan® Structural Insulated Panel (SIP) system. With its structural strength, energy efficiency, and quick assembly time, Insulspan SIPs are the perfect material to use as the structural shell of an ADU. As a result of the shell’s ability to structurally support itself, you can configure the interior of the unit any way you want to best meet your needs.

Reasons Why Building an ADU or Other Structure with Insulspan SIPs makes sense:

Rising Popularity of Accessory Dwelling Units (ADUs)

As cities sprawl and infill redevelopment happens, accessory dwelling units (ADUs) are becoming quite popular. This is because, in part, they increase the available supply of affordable housing. Some municipalities now require these units. However, ADUs, also known as laneway houses, granny flats, in-law units, and carriage houses, are more than a way of planning and managing urban sprawl. They make ideal structures for multi-generational families to live together while still maintaining private spaces for everyone.
