Plus Space™ ADUs: Energy Efficient, Completely Configurable SIP Kits

Insulspan® Structural Insulating Panels is pleased to introduce Plus Space™ ADUs by Insulspan.

Plus Space™ by Insulspan is the next wave of accessory dwelling units (ADUs). The highly energy efficient, completely configurable SIP Kits are designed to give each person the flexibility they deserve when adding plus space to their yard. While most ADU companies offer pre-designed floor plans in a small selection of sizes, Insulspan has created something completely different. Plus Space™ ADUs are comprised of a self-supporting structural shell made of Insulspan’s ready-to-assemble (RTA) structural insulated panels (SIPs). This structural strength of the SIPs is what gives owners the ability to make their Plus Space™ accessory dwelling unit exactly what they want by configuring the interior layout to exactly meet their needs.

Plus Space™ ADUs are also unique in marketplace because they are highly energy efficient. The structural insulated panels used in Plus Space™ kits are created using continuous expanded polystyrene (EPS) insulation structurally laminated to two boards of performance-rated oriented strand board (OSB). The continuous insulation combined with larger panel sizes minimize thermal breaks and reduce heat transfer between unit’s interior and exterior. Because of the SIPs high R-values, Plus Space™ ADUs provide an energy efficient housing option that is both high quality and sustainable.

“We are excited to introduce Plus Space™ ADUs by Insulspan and our portfolio of configurable floor plans. This highly energy efficient alternative to traditional ADUs meets the needs of our clients and fills a niche in the broader ADU market.” -Stephen Munn, General Manager of Insulspan

Plus Space™ ADUs include a variety of building styles and currently offer:

  • Carriage House Plans: 500-700 square feet.
  • Single-level Suite Plans: 300-400 square feet.
  • Studio Plans: 160 square feet.
  • Pool House Plans: 500-700 square feet.

Plus Space™ ADUs were created to meet the demand for more living space in cities that are facing urban sprawl. For cities like Seattle, Portland, and San Francisco, these ADUs can offer a solution to the growing affordable housing crisis. For cities like Ann Arbor, Grand Rapids, and Toledo, these highly energy efficient ADUs can become a home office, she-shed, gym, or yoga studio while also filling the need for affordable housing.
