At least half of the manufactured homes being sold are either double-wide or triple-wide, ranging from about 1,100 square feet to as big as 2,700 square feet.
Builders and contractors have found the dramatic reduction in assembly time and less material waste have saved them time and money. They have also found that steel framing ensures a stronger and higher quality construction.
Many builders have found the economical benefits of roll forming their own steel studs when other builders have been finding success with steel stud panelization.
The panelization process starts by roll forming steel studs for trusses or wall panels inside a factory. The steel studs are assembled directly in the factory and then the trusses and walls are shipped to the jobsite where the building is erected.
Residential steel framing utilizes cold-formed steel members for walls, floors, and/or roofs.
The framing members are C-sections with standard dimensions similar to wood framing studs.
Steel framing can be a cost effective alternative to wood framing.
Steel mills produce galvanized sheet steel, the base material for steel members. Sheet steel is roll-formed into shapes used for framing.
The sheets are zinc coated (galvanized) to prevent corrosion.
Although there are a variety of shapes available, the primary shapes used in residential construction are the C-shape stud and the U-shaped track.
Framing members are generally produced in thickness of 12 to 24 gauges with 3-½ and 5-½ widths.
Manufacture of steel framing members adheres to strict tolerances, which results in consistent strength, straightness, and dimensionally stable members.
Steel framing provides excellent design flexibility due to the inherent strength of steel, which allows it to span longer than wood, and also resist wind and earthquake loads.
Architects and builders, wanting to reduce dead load, construction time and costs, are more frequently utilizing light gauge steel stud framed panels with any of several different finish materials to construct exterior walls on their building.
Remarkable cost savings are possible when the steel stud panels are fabricated off the job site.
Realizing the importance of quality assurance systems within the home building industry, new Home Generation, INC. Home design on a manufacture scale, intends to introduce a residential home design with a roof membrane system that will exceed the most recent version of ASTM D3161, modified to reflect 110 mph fan-induced wind speeds or Miami-Dade protocol PA 107, be certified to meet minimum wind speeds of 110 mph and must be installed per manufacturers’ specifications.
Roof systems may have only one layer of covering. Hurricane straps or other hardware that connect the roof to the walls must be installed with the proper number and type of crews per manufacturers’ specifications and be designed using rational analysis based on wind loads calculated according to ASCE 7-98, using a Basic Wind Speed defined by ASCE 7-98 but not less than 120 mph.
A secondary water resistance system and under layment material will be used on the roof, applying the 16” to 18” metal roofing panels atop.
In order to satisfy customers consistently, we have incorporated in our home design a planned, systematic and documented approach to quality.
A key ingredient in the success of our Paneled Structural System are the pre-panelized load-bearing metal stud walls with SEALECTION™ 500 spray foam injected between the studs, much cheaper then Dow Styrofoam or Rigid Foam Board BLUECOR® Brand Insulation made of Extruded polystyrene (XPS); while SEALECTION™ 500 adheres to both exterior/interior wall covering.
The exterior walls will have SEALECTION™ 500 spray foam insulation injected off the assembly line.
SEALECTION™ 500 spray foam is an open cell semi-rigid spray-applied polyurethane foam insulation system which is made up of millions of microscopic cells that simultaneously insulates and air-seals.
It is applied as a liquid that expands over 120 times its original volume completely filling any cavity. It "SEALS" off those drafty areas like baseboards, headers, sill plates, around windows, doors, electrical outlets, pipes, etc.
It virtually eliminates uncontrolled air leakage throughout the building envelope thereby reducing energy losses.
The foam creates a continuous air barrier by adhering to other building materials (wood, plywood, foam board, etc.) and is available through DEMILEC USA LLC, 2925 Galleria Drive, Arlington, Texas 76011 (817) 640-4900. http://www.sealection500.com/dem/s500/index.php
