Why SPS?
Structural Panel System
SPS 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. SPS Panels can be made just like SIPs, in various thicknesses and sizes, up to 12' x 40'
Similarity to ordinary building
Switching from a stick-built to a SPS build is a very easy process that requires few changes. Many standard tools are still used when building with SPS. But unlike the power lifting equipment required for SIPs panels, which can weigh up to 800 pounds, SPS panels can be lifted by as little as one or two installers. Also, SPS panels are extremely friendly to field modifications if needed.
Construction of SPS Panel
SPS Panels evolved from stick-built and SIPs construction, which used dimensional lumber for corner connections and plates. Compared with stick framing, SIPs and ICFs, constructing with SPS Panels eliminates steps, lightens material handling and time is saved.
How SPS Panels Work
SPS Panels achieve structural integrity with an I-beam effect by using galvanized steel studs as the flanges of the·1·beamand 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 rigid1-pound per square foot EPS core serves as both the insulated component and web of the·1·beam panel. The thicker the SPS Panel, the more load they are able to carry and the greater the R-Value.
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 SPS Panels buildings includes precision cutting and shaping of each panel to match specification and exact shop drawings.
Lifetime of Benefits
• SUSTAINABLE - components made from 100% recyclable material.
• HEALTHY - panels do not let off toxic gasses and do not mold or attract pests
• RESILIENT - have a hurricane rating of up to 200 mph and earthquake systemic rating 5.7
• INSULATED - provide R Values of up to R-75.
• ENERGY EFFICIENT - reduces cooling costs for the life of the structure.
• LOAD-BEARING - engineered-stamped to ensure true structural integrity.
• DURABLE - panels never break down.
• SOUND/NOISE REDUCTION - additional characteristic of panels is the inherent sound reduction from the EPS.
• ENVIROMENTAL IMPACT -Homeowner is contributing to the conservation of energy resources, while reducing their overall environmental footprint.
SPS Versus - Stick Construction and Masonry Construction
Versus Traditional Stick Construction
- Stick construction is labor intensive
- Framers required for stick construction can be difficult to retain (shortage of available skilled framers)
- Air sealing of stick construction is labor intensive and expensive
- Wood is susceptible to rot and pest infestation
- Stick construction requires separate contractor to install insulation
- Thermal bridging through wood studs and plates – results in very low thermal efficiency (R-Values)
- Stick building presents design limitations
- SPS Panels are quick to install and require less skilled labor
- R-Values of SPS Panels are substantially higher
- Labor costs to install SPS Panels are less
- Time to erect building using SPS Panels is substantially less than time required to construct stick frame
Versus Masonry Construction
- Material costs of masonry are extremely high
- Masonry walls have no R-Value and require substantial additional materials to insulate
- Installation of masonry requires highly skilled laborers who are expensive to employ and difficult to locate
- Masonry difficult to insulate – expensive and labor intensive
- SPS Panels can easily accommodate masonry veneer for stone or brick exterior look
- Masonry retains moisture and dampness, requiring ventilation
- Masonry building presents design limitations
- SPS Panels are quick to install and require less skilled labor
- R-Values of SPS Panels are substantially higher
- Total material costs (including required insulation) of SPS Panels is substantially less expensive
- Labor costs to install SPS Panels are a small fraction of the most of installing masonry
- Time to erect building using SPS Panels is substantially less than time required to construct with masonry
