Description

This resource boils down the possibilities to “right-size” wall bracing for optimal wall designs that also make use of the many benefits and capabilities of FPIS. View the full FACTS Sheet Library.

Description

There are many acceptable ways to mount and detail windows for support and weather resistance. This page provides window installation instructions based on research conducted on walls with continuous insulation.

Description

The code compliant use of FPIS for energy code applications requires consideration of other factors such as appropriate methods for connection of claddings through FPIS materials of various thicknesses and various substrates.

Description

This guide provides designers, code officials and builders a basic understanding of how to apply the IRC bracing provisions for code-compliant dwellings and how the IRC bracing provisions can be used to create maximum value in a diverse housing market.

Description

Simpson Strong-Tie developed this quick and easy tool to help calculate the required length of wall bracing in accordance with the IRC. The tool provides printed output of the bracing requirements along with a summary of input information and factors used in the calculations.

Standard Requirements for Wind Pressure Resistance of Foam Plastic Insulating Sheathing Used in Exterior Wall Covering Assemblies

Wall bracing is a common source of confusion and misapplication although it is of critical importance when designing, performing plan review, building or inspecting a structure. This full-color illustrative guide was developed to help building designers, builders, building officials and others using the code in the application of the lateral bracing requirements of the 2018 International Residential Code® (IRC). The authors identify and explain the key elements of wall bracing and demystify the IRC prescriptive bracing provisions.

Additional Information

This Simpson Strong-Tie technical bulletin is for use with the 2012, 2015 or 2018 International Residential Code (IRC). It provides information about the Simpson Strong-Tie products that meet the connector and anchorage requirements for braced wall panels constructed in accordance with IRC Section R602.10.4
