Not All Buildings Are Created Equal
Steel SIP (aka SSIP) construction is stronger than conventional framing. SSIP homes are designed to meet requirements as high as 155mph wind loads. That strength also stands up to earthquakes with SSIPs having the highest seismic rating available from the state of California.
What makes Steel Structural
Insulated Panels SSIPs resistant to high winds?
During a hurricane, tornado, or any high wind episode, much of the building damage seen on the news consists of partially lifted roof coverings and blown out eaves or soffits. The loss of shingles leads to water entry and drywall saturation. The opened soffit allows the wind to enter the roof. At this point, the roof is in danger of being torn apart piece by piece as the pressure of the wind acts on the various sheathing panels and framing members looking for a weak point. On the other hand, with Steel SIP construction, strength is integral. The panel materials themselves are impervious to water, avoiding rain damage even if the roof coverings are blown off. Additionally, the integrated SSIP system does not permit the wind grab hold of any element to loosen it and open up the housing envelope.
We don’t have hurricanes, why should it matter?
Whether out west, on either coast, down south, or in the Midwest, each region has its own form of severe weather: hurricanes, tornadoes, typhoons, blizzards, sandstorms, tropical storms, severe thunder storms. Wind is a constant. While all buildings might not need the strength required by the Miami-Dade County, even the most basic ThermaSteel steel SIP system provides a far greater level of protection than other means of construction.
What is Miami-Dade?
ThermaSteel SIPS are set apart from stick built structures and even OSB SIPS in that they have the integrity and strength to have passed the rigorous test protocols required by Miami-Dade County Florida. Subjected the most severe hurricane weather in the country, this region has adopted strict building requirements, restricting methods to a select few that will withstand the potential beating of multiple hurricanes a year.
To complete the testing, a standard 5-1/2″x4’x8′ ThermaSteel wall panel, reinforced on the exterior side with our standard 24 gauge G-90 galvanized steel studs closely spaced was tested according to the Miami-Dade requirements at the Hurricane Test Laboratory, Inc. in Riviera Beach, FL. Multiple wall samples passed the testing with plenty of margin.
