How Shield Panels 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 are 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.

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 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.

Shield Panels Galvanized Steel Stud Framing:

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.

Shield Panels Building System and the Environment

It is important to keep in mind that all insulation and building materials have an environmental footprint. In fact, most modern buildings and insulation materials are quite carbon-intensive to produce. Cement, for example, produces huge amounts of CO2 in production, as do insulating materials like rockwool and fiberglass. However, Expanded Polystyrene (EPS) insulation is 98% AIR and can return up to 200 times the amount of energy required to produce it and reduce emissions by up to 100 times the volume produced during the manufacturing process. EPS is non-toxic and totally inert. It contains no Chlorofluorocarbons (CFCs) or Hydrofluorocarbons (HCFCs), and never has at any time during its life cycle. It is also totally absent of any nutritional value, so no fungi, mold, or micro-organisms can grow within EPS. Structures built with SHIELD Panels experience very low air infiltration creating controlled interior environments with high fresh filtered air supplies for the occupants.

Passive Housing

Passive building consists of design principles used to attain a measurable level of energy efficiency within a specific quantifiable comfort level in any type of building. We are the first, and currently the only, panel system in the US that is certified by the Passive Housing Institute US (PHIUS).

The 5 Passive Housing Scientific Principles:

  • Employs continuous insulation throughout its entire envelope without and thermal bridging.
  • The building envelope is extremely airtight, preventing infiltration of outside air and loss of conditioned air.
  • Employs high performance windows and doors- solar gain is managed to exploit the sun's energy for heating purposes in the heating season & to minimize overheating during the cooling season.
  • Uses some form of balanced heat - and moisture-recovery ventilation.
  • Uses a minimal space conditioning season.
