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
 Steel panels are manufactured on a continuous line making them available in square pre-cut lengths in ¼ ” increments, but only charged to the nearest ½ ft., OSB often rounds up to the nearest 2 ft. increment – making you pay for waste that gets thrown away
 Higher ” R – Value” denser foam provides a 4.25 R- value per inch of foam
 No Termites … Impervious to termites and carpenter ants , foam core is borate treated
 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.
 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
