2.  **Name and address**

> **of Manufacturer**
>
> > This Structural Engineering Bulletin (SEB) should be filed with
> > other SEBs and related Bulletins on materials or products as
> > required by prescribed procedures.
>
> 1\. General:

This Bulletin sets forth specific requirements under the Technical
Suitability of Products Program for determining the eligibility of
housing to be constructed under HUD mortgage insurance, or other HUD
housing programs.

> 2\. Scope:
>
> This Bulletin applies only to the structural features of this method
> of construction. Final determination of eligibility is made by the
> appropriate HUD Field Office. Other factors considered by the Field
> Office will be valuation, location, architectural planning and appeal,
> mechanical equipment, thermal characteristics, and market acceptance.
> Consideration is also necessary to determine whether a specific
> property will qualify under the specific HUD program, when constructed
> according to the method outlined in this Bulletin, and where the
> structure is to be located.

-2-

> In geographical areas subject to hurricanes, earthquakes, or other
> severe conditions affecting dwelling structures, the HUD Field Office
> or Homeownership Center shall require additional safeguards in
> proposed designs, when necessary.
>
> 3\. Minimum Property Standards (MPS):
>
> Compliance with HUD MPS will be determined by the HUD Field Office or
> Homeownership Center on the same basis as submissions involving
> conventional construction, except for the special features described
> in this Bulletin.
>
> 4\. Inspection:
>
> Field compliance inspections covering conventional items of
> construction and any special features covered in this Bulletin shall
> be made in accordance with prescribed procedures.
>
> The appropriate HUD Field Office or Homeownership Center shall furnish
> a copy of a HUD field inspection report to Headquarters, FHA
> Standards, Office of Manufactured Housing Programs, when there is:
>
> a\. Evidence of noncompliance with portions of the system of
> construction described in this Bulletin.
>
> b\. Faulty shop fabricated, including significant surface defects.
>
> c\. Damage to shop fabricated items or materials due to improper
> transportation, storage, handling, or assembly.
>
> d\. Unsatisfactory field workmanship or performance of the product or
> system.
>
> e\. Any significant degradation or deterioration of the product or
> evidence of lack of durability or performance.
>
> Periodic plant inspections will be made by HUD designated
> representatives in accordance with their prescribed procedures.
> Factory inspection reports shall be submitted to HUD Headquarters,
> upon request.
>
> 5\. Certification:
>
> The manufacturer named in this Bulletin shall furnish the builder with
> a written certification stating that the product has been manufactured
> in compliance with the HUD Minimum Property Standards (MPS), except as
> modified by this Bulletin. The builder shall endorse the certification
> with a statement that the product has been erected in compliance with
> HUD MPS except as modified by this Bulletin, and that the
> manufacturer\'s certification does not relieve the builder, in any
> way, of the responsibility under the terms of the Builder\'s Warranty
> required by the National Housing Act, or under any provisions
> applicable to any other housing program. This certification shall be
> furnished to the HUD Field Office upon completion of the property.

> [OUTLINE DESCRIPTION, CATEGORY II CONSTRUCTION]{.underline}:
>
> [GENERAL]{.underline}:
>
> Shop fabricated structural insulated roof, wall, and floor panels for
> one-, two- and three-story dwellings are furnished in this method of
> construction. Panels consist of oriented strand board (OSB) skins and
> expanded polystyrene (EPS) foam cores. Panels are transported to the
> building site where they are connected together.
>
> Conventional construction may include various types of interior and
> exterior finish materials. All materials and methods of installation
> shall be in accordance with the manufacturers published installation
> instructions, HUD Minimum Property Standards, Use of Materials
> Bulletin (UM), and Materials Releases (MR), except as may be
> specifically noted herein. Plumbing, heating and electrical systems
> are shop installed and field connected.
>
> This Bulletin is based on a structural review of AFM R-Control
> structural insulated panels for one-, two- and three-story dwellings.
> Foundation design and nonstructural items (such as architectural,
> plumbing, heating and electrical features) are not covered by this
> Bulletin.
>
> [SPECIFICATIONS]{.underline}:
>
> Form HUD-92005, \"Description of Materials\" specifying only the
> structurally related items (Nos. 1 to 12, 14, 26 and 27), as
> originally submitted for determination of technical suitability,
> describes the materials that shall be used in construction of housing
> units under this system of construction.

> [SPECIAL CONSTRUCTION FEATURES]{.underline}:
>
> [General]{.underline}: The AFM R-Control Structural Insulated Panels
> vary in size from 8\' to 24\' in length, and from 8\' to 10\' in
> height (10\' high panels are limited to 8\' widths). Panel core
> thicknesses range from 3 ½\" through 11 ¼\". The facing thickness of
> the OSB is 7/16\" minimum. Panels can be used individually or may be
> connected to form larger sections and assemblies.
>
> [Facings, Foam Core and Adhesive]{.underline}: Panels consist of two
> layers of OSB facing. The OSB facings must bear a stamp indicating
> compliance with DOC PS2-92 (Performance Standard for Wood-Based
> Structural-Use Panels). The expanded polystyrene (EPS) core material
> is nominal 0.95 pcf density, modified polystyrene insulation board in
> accordance with ASTM C 578-01 and AFM/UL certified. Skins shall be
> bonded to the foam cores with a high-quality structural adhesive
> listed in the AFM Quality Control Manual.
>
> [Field Assembly]{.underline}: Each structure built using R-Control®
> Structural Insulated Panels shall be designed by a registered design
> professional. Drawings shall be provided that bear the design
> professional's registered stamp or seal. Such drawings shall contain
> specific instructions with regard to connections, erection, and
> installation of the panels, and shall be available at all times during
> installation.
>
> The R-Control® Structural Insulated Panels are connected to each other
> at the panel edges through the use of splines. The splines are
> field-coated with Do-All-Ply sealant and fastened with 8d box nails at
> 6 inches on center, or an equal approved by AFM.
>
> The top and bottom plates of the panel are dimensional wood plates
> sized to match the core thickness and installed with Do-All-Ply
> sealant and fastened with 8d box nails at 6 inches on center, or an
> equal approved by AFM. The Do-All-Ply sealant is applied along the
> base plate prior to the panel placement.
>
> [DESIGN AND CONSTRUCTION REQUIREMENTS]{.underline}:
>
> [Allowable Structural Loads for Panels]{.underline}
>
> Allowable axial, transverse, racking, header, and diaphragm loads are
> noted in Tables 1 through 8. For loads greater than those specified in
> Tables 1 through 6 and Table 7, the specific condition shall be framed
> by other methods to meet applicable code requirements.
>
> Openings in the wall panels shall be limited to 48 inches in width and
> to the allowable loads specified in Table 7. For openings greater than
> 48 inches, loads shall not exceed the those indicated in the header
> load design chart or shall be framed to meet current requirements
>
> [Fire Protection and Interior Finish]{.underline}: The polystyrene
> foam core shas a flame spread rating of not more than 25, and a smoke
> development rating of not more than 450 when tested in accordance with
> ASTM E-84. Panels shall be covered on the interior of the building by
> an approved 15-minute thermal barrier.
>
> -7-
>
> [Exterior Finish:]{.underline}
>
> The exterior of the wall panels shall be covered with an exterior wall
> covering acceptable to AFM R-Control and in compliance with the
> Minimum Property Standards.
>
> [Framing of Load bearing Walls]{.underline}: Wood-to-wood connections
> shall be provided between bearing walls and roof-ceiling or floor
> construction. Floor covering, including carpeting and vinyl tile,
> shall not be continued under load bearing walls.
>
> [Roof Construction]{.underline}: Roof framing and coverings shall be
> constructed to comply with the Minimum Property Standards. Roofs with
> hot-asphalt or hot-coal tar pitch are prohibited.
