by Disclaimer} the materials in this guide are ready to be used as a reference for fire and sound insulation lightweight steel frame components.
Although every effort has been made to ensure that the material is technically correct, it only provides a brief description of the tested components.
It should not be used until you first check the source file of the testing agency for a complete description of the component.
The steel frame alliance and its organization members guarantee or assume the responsibility that the materials are suitable for any general or specific purpose.
Note that some components are built using proprietary products that may not be available in all geographic regions.
For these details, please refer to the source file of the testing organization.
Note: 1 When considering steel floor and wall assemblies, reference should be made to the ULC design number (published in the fire resistance catalogue of Underwriters Laboratories Canada) and the NRCC report / assembly number (research publication of the Building Research Institute of the National Research Council of Canada) for the design of Canadian building code jurisdictions.
2.
For non load bearing wall components, the thickness of steel studs shall comply with astmc645, Standard Specification for non structural steel frame members, in which the minimum thickness is specified as 0.0179 inch (0.455 mm) before protective coating is applied.
3.
Most of the sound data included in this guide are based on the following report: Warnock, A.C.C., sound transmission level and impact insulation level rating of steel frame components, report no.
b3436 1.
Institute of architecture, National Research Council of Canada, Ottawa, Ontario, Canada.
The above report surveys existing published sound test reports, which are represented by alphanumeric acoustic test identifiers in the source column.
The letter prefix in the identifier indicates various acoustic test laboratories.
The report also provides a number of acoustic “estimates”, which are marked with an asterisk to indicate the above report.
In some cases, The following codes will appear in the acoustic data to represent the material: air – voids in the structure (a layer of thick air) car-und – carpet and backing cembrd – cement board (with thickness) g – gypsum board (with thickness) GFB – glass fiber felt (with thickness) Ni – uninsulated NRC – inelastic metal channel RC – elastic metal channel RFB – rock fiber (mineral wool) pad (with thickness) Recommend official account for several industries:.
