Design for a Cold-formed Steel Framing Manufactured Home: Technical Support Document
Manufactured Housing Research Alliance, New York, 2002
The use of light gauge steel in the structural system of residential construction has taken hold in some site building markets but potentially offers far more value to the manufactured home industry. MHRA is coordinating an effort to develop a market competitive structural design, based on light gauge structural steel technology and suitable for the home manufacturing environment.

Structural Insulated Panels in a Manufactured Home Roof System: Engineering Guidelines
Manufactured Housing Research Alliance, New York, 2000
Structural insulated panels, or SIPs, are a building component that behaves structurally like an I-beam. Although SIPs have a higher first cost than conventional framing methods, their superior structural and thermal properties, ability to be manufactured to high dimensional tolerances, and potential to speed home assembly make them a compelling technology for HUD-code homes.

Guidelines for Anchor System Design: Technical Support Document
Manufactured Housing Research Alliance, New York, 2000
In an effort to improve the performance of foundation systems, MHRA coordinated the development of guidelines for anchor system design and installation. The engineering analysis of the field-testing of anchors resulted in the design of an easy-to-use anchor chart instruction card.

Manufactured Housing Fuel Switching: Field Test Study
Manufactured Housing Research Alliance, New York, 1999
The purpose of this field study was to measure indoor air pollution and moisture levels in fuel switching manufactured homes. Fuel switching is defined as any use of non-electric heaters to supplement electric space heating in manufactured homes. A sample of 21 manufactured homes was recruited for field-testing.

Measured Permeance Values for Selected Interior Wall Assemblies
Manufactured Housing Research Alliance, New York, 2000
In March 2000, HUD issued a proposed waiver concerning condensation control for exterior walls of manufactured homes sited in humid climates. This proposed waiver would permit the optional placement of the vapor retarder on the outside of exterior wall insulation in hot, humid climate regions with the provision that the interior wall board and finish must attain a combined perm rating of 3.0 of greater. MHRA collected samples of wall constructions from manufacturers and coordinated a series of test, applying the ASTM E96-95 protocols, to measure perm ratings for wall systems of manufactured homes currently in use in hot and humid climates.
