SHIELD™ Panels SPS (Structural Panel System): SHIELD™ Panels are a unique building product because they combine superior structural support and insulation in one panel, but without the weight and difficult maneuverability of typical SIPs. However, SHIELD™ Panels, like SIPs, are available in various thicknesses and sizes, up to 12’ x 40’.


How SHIELD™ Panels Are Similar to Stick & SIPs Construction: Switching from stick-built to a SHIELD™ Panel is a very easy process that requires few changes. Many standard tools are still used when building with SHIELD™ Panels. But unlike the power lifting equipment required for SIPs panels, which can weigh up to 800 pounds, SHIELD™ Panels can be lifted by as little as one or two installers. Also, SHIELD™ Panels are extremely friendly to field modifications if required. To aid in learning the process of installing SHIELD™ Panels, Guardian Structural Technology offers on-site installation training or recommends experienced installation teams.


How SHIELD™ Panels Surpass SIPs and ICF Construction: SHIELD™ Panels evolved from stick-built and SIPs construction, which use dimensional lumber for corner connections and plates. Compared with stick framing, SIPs and ICFs, constructing with SHIELD™ Panels eliminates steps, lightens material handling and time is saved.


How They Work: SHIELD™ Panels achieve structural integrity with an “I” beam effect by using galvanized steel studs as the flanges of the “I” beam and a rigid plastic foam core of expanded polystyrene (EPS) as the web of the “I” beam. The key to its structural performance is that the galvanized steel studs inserted flush with the EPS core on both sides and fastened with industrial grade metal fasteners. This design prevents exterior and interior finishing materials from buckling. The rigid 1-pound per square foot EPS core serves as both the insulated component and web of the “I” beam panel. The thicker the SHIELD™ Panel, the more load they are able to carry and the greater the R-Value.


How They Have Consistent Quality: The galvanized steel studs and EPS foam core are rigidly fastened together in the factory with high-grade industrial screw under strict quality control standards. Fabrication of SHIELD™ Panels buildings includes precision cutting and shaping of each panel to match specification and exact shop drawings.


There are many reasons why steel framing has come to the forefront as one of the best and most feasible alternative building materials for residential and commercial construction. Steel is a superior construction material with many benefits.

Architect at Work

Benefits to Architects

  • Most cost effective mid-rise structural material

  • Highest strength-to-weight ratio of any building material

  • Easy to meet specific design & dimensional requirements

  • Inorganic - will not rot, warp, split, crack, or creep

  • Dimensionally stable - does not expand or contract with moisture content

  • 100% recyclable

  • Less scrap and waste (2% for steel vs 20% for lumber)

Construction Workers

Benefits to Builders

  • Lightweight, easily transported, stored, handled and installed on job sites.

  • Compliant with specific building code standards.

  • Easy to cut and shape with ordinary tools to ensure tight joints, reducing heat loss.

Couple and Builder

Benefits to Building Owners

  • High strength results in safer structures, less maintenance and slower aging of structure.

  • Fire safety - doesn't burn or add fuel to the spread of a fire.

  • Not vulnerable to termites.

  • Not vulnerable to any type of fungi or organism, including mold.

  • Less probability of foundation problems - less weight results in less movement.

  • Less probability of damage in an earthquake.

  • Lighter structure with stronger connections results in less seismic force.

  • Less probability of damage in high winds.

  • Stronger connections, screwed versus nailed.


Expanded polystyrene (EPS) is a product that provides smart solutions and durable, efficient results. Equally important, EPS is a sustainable product that is recyclable and environmentally sound. The lifecycle of EPS has been studied, documented and proven to leave a smaller footprint on our planet than comparable materials. It is a smart option for building, insulating and protecting, and a responsible choice for the environment. MBDC, a product and process design consultancy established by architect William McDonough and chemist Dr. Michael Braungart, determined that Styropor® EPS is suited for circulating in a cradle-to-cradle life cycle as a technical nutrient.
