Wall Bracing for Hurricane, High Wind, and Seismic Resistance

Guide

Guide describing how to construct the walls of a home with bracing to resist high wind and earthquake loads.

Advanced framing details include corners that are constructed with fewer studs or studs aligned so that insulation can be installed in the corner.

Image

Framing is built around the window before exterior rigid foam is installed on the exterior walls around the window.

Image

The advance-framed 2x6 24-inch on-center walls are covered with netting then filled with R-23 blown fiberglass.

Image

Stucco is installed over rigid insulation, which is installed over a drainage plane consisting of a drainage gap and building wrap layer over the sheathing

Image

Wrong – The gable end wall failed because the rigid foam sheathing was not backed up by plywood or OSB.

Image

Structural insulated panels offer a continuous layer of thermal protection and draft resistance around the home and come from the factory precut for fast assembly.

Image

The double walls form a 12-inch cavity that was sheathed with a coated OSB then coated with 3 inches of closed-cell spray foam; they will be filled with 9 inches of blown fiberglass.

Image

These factory-built walls consist of 9.5-inch I-studs sheathed with coated OSB, faced with OSB, and dense-packed with cellulose; a second interior surface of drywall is added to provide a 1.5-inch cavity for electrical wiring.

Image

The OSB roof decking product comes with an adhered radiant foil barrier which helps to prevent heat transfer in or out of the vented attic, while R-13 unfaced fiberglass fills the advanced-framed 2x6 walls.

Image

Right - Blocking has been installed between the ceiling joists and air sealed in place with canned spray foam to stop air flow beneath the attic knee wall.

Image

Drywall was removed and the existing 2x4 walls were filled with 3.5 inches of dense-packed cellulose. Outside, the ½-inch plywood was topped with house wrap, 1.5 inches closed-cell rigid foam, 1x3 furring strips, and fiber cement siding.

Advanced Framing vs Traditional Framing

Video

Video describing traditional 2x4 16 inch on center framing versus advanced framing with 2x6 stud walls at 24 inch on center, insulated corners and headers, wall stud-ceiling joist alignment, etc. providing a strong wall with more room for insulation.

Technology Solutions Case Study: Stand-Off Furring in Deep Energy Retrofits

Case Study

Case study describing a stand-off furring strategy that minimizes the physical connections to each existing wall stud, uses spray foam to encapsulate existing siding materials (including lead paint), and creates a vented rain screen assembly to promote drying.
