OSB currently is the main core of the SIPs marketplace, but steel is coming on strong due to the many ovbious benefits
Any SIP construction will save 50 – 60% in energy costs, are 3 times stronger than frame, and are more environmentally friendly.
Steel is a better choice for the following reasons
Advantages of Steel SIPs vs.OSB
Steel will not warp, swell, twist, rot
Rain during construction do not affect materials in any way
No cranes needed for installation a steel SIPs are lighter than OSB
The underside of the roof panel automatically forms an attractive finished soffit overhang or exterior porch ceiling.
Joints are a T&G friction fit they do not require splines, mastic or fasteners greatly speeding installation time
Steel is more stable during manufacturing and panels are held to 1/16” tolerance
OSB is limited to 24ft. in length …Steel SIPs are available up to 53ft. in length, eliminating butt joints
No foam grooving is required for window and door openings, after cutouts are made, openings are simply “picture framed” with 18.ga. steel channels
The steel skin is the “vapor barrier” on walls no additional covering is required before siding is applied
Eave overhangs can be 4 feet with no additional support
Sound Control – utilizing a 1-1/2” steel furring strip creates a dead air space for improved STC ratings.
Wiring – utilizing that same air space, wiring is much easier than fishing wire thru OSB and any future retrofit wiring is easier.
Impervious to termites and carpenter ants
Will not support mold growth – painted galvalume steel skins are UDSA approved
Indoor air quality is better due to the tighter and cleaner construction material of the interior
Any steel building is safer from lightning strikes
“Monocoque construction” All connections and attachments are with screws having greater pullout strength than nailing
For economy or insulated utility buildings, steel SIPs have been left exposed as the finished siding and roofing.
Zurich Ins. In partnership with the Steel Framing Alliance offer reduced builders risk insurance premiums
In Florida and other hurricane prone regions Steel SIPs are 30% less to insure that block/truss and 53% less to insure than wood frame construction
