Legendary Panels

Providing Legendary Resources to Rapidly Design-Build Low-Cost High-Performance Properties Wordlwide

What are SIPs

Structural Insulated Panels (SIPs) are high performance building panels made of expanded polystyrene sandwiched between oriented strand board (OSB) for use in walls, floors, and roofs that make buildings stronger, more durable and more energy efficient than conventional.


There are many benefits to a SIP-built home or building. One of the most important energy efficiency and environmental friendliness. Using SIPs is the best way to become LEED certified, Energy Star Compliant and HERS ratings are outstanding compared to other methods.

Nailbase Retrofit

Nailbase is a cost-effictive solution for remodeling or rennovating an existing home or building when speed, budget and dramatically increasing energy efficiency are the goals. A retrofit from the outside in, nailbase creates an airtight envelope that will last a lifetime.
