Structural Insulated Panels

MM&I Structural Insulated Panels (SIPs) are made with expanded polystyrene (EPS) foam insulation with engineered oriented strand board (OSB) laminated to the top and bottom faces which we call skins. Our SIPs begin as an 8’ x 24’ panel with thicknesses ranging from 4-1/2”, 6-1/2”, 8-1/4”, 10-1/4”, and 12-1/4”.

Our SIP packages are divided into three categories:

  • Ready to assemble
  • Pre-cut
  • Blank

The ready to assembly SIP package is typically the package of choice by the majority of our clients as it reduces construction time and improves efficiency. This system includes panel shop drawings, precut panels with lumber preinstalled in the factory wherever possible and accessories are included in the package. Each project is specific and the client needs to refer to the written contract for details.
