Company Background

Murus was founded solely to research, develop and manufacture the highest-performing structural insulated panels available (SIP).

SIPs have been used in construction since 1952. They consist of a rigid foam insulation core bonded between two layers of rigid sheathing, called "skins." SIPs offer:

  • superior structural strength
  • unmatched energy efficiency
  • reduced construction and labor time
  • plus a host of other benefits

Murus remains committed to the idea that structural insulated panels are a superior construction method. Murus is committed to the goal of providing superior insulated panel products and service to its customers.

As a company, we have maintained a position of leadership in our industry because of several key attributes:


Since its founding in 1987, our manufacturing facility in Mansfield, PA, produces structural insulated panels (SIPs)—and nothing else. By continually focusing on our product and process improvements, we maintain the highest level of quality possible.

Customer Service

Our customers work directly with knowledgeable Murus team members to receive the best in customer care. In addition, builders, architects, engineers, and homeowners all benefit from our Total Client Support program.


We incorporate diligent quality control procedures, and contract with an independent third-party quality assurance agency to audit and inspect our processes and insulated panel products.


Murus works continuously to create new products and develop new methods and processes that enhance product qualities. From a proprietary manufacturing process to patented Cam-Lock panel connectors, Murus creates the advances that make a superior insulated panel system even better.
