Sealants, Insulation and Barriers and How to Install Them
Published in Stan Harbuck, Donna Harbuck, Residential Energy Auditing and Improvement, 2021
Another type of batt insulation that was originally designed for metal buildings is manufactured in 2- to 6-ft-wide rolls or batts. A common application in the residential arena is to attach it at the sill plate above the foundation wall in basements or crawlspaces, and drape it down to the floor, as in Figure 6-4. It is not recommended to use fiberglass insulation on the walls of basements or crawl spaces due to the possible buildup of condensation inside the insulation. The condensation is made even worse if the fiberglass has any kind of Kraft or foil facing. Foam board or spray foam is the insulation of choice for these areas.
Roof and floor sheathing under vertical and lateral loads (horizontal diaphragms)
Published in Abi Aghayere, Jason Vigil, Structural Wood Design ASD/LRFD, 2017
In a general structural sense, a diaphragm is a plate like structural element that is subjected to in-plane loading. In concrete building or a steel-framed building with a concrete slab, the concrete slab acts as the diaphragm. In a wood structure, the diaphragm is mainly the roof and floor sheathing, but drag struts and chords are also critical members in the diaphragm and load path (Figure 6.6). The sequence of the load path can be summarized as follows:Lateral wind or seismic loads are imposed on the diaphragm.For wind loads, the wind pressure is applied to the wall sheathing and wall studs, which is then transferred to the diaphragm and the foundation at the base.For seismic loads, the lateral force is assumed to transfer directly to the diaphragm.Loads are transferred from the diaphragm sheathing to the floor framing through the diaphragm fasteners.Loads are transferred from the framing to the drag struts (where drag struts are not present, the loads are transferred directly to the shear walls).Loads are transferred from the drag struts to the shear walls (vertical diaphragms).Loads are transferred from the wall sheathing to the wall framing through the shear wall fasteners.Loads are transferred from the wall framing to the sill plate.Loads are transferred from the sill plate to the anchor bolts.Loads are transferred from the anchor bolts to the foundation.

At the bottom, a sill plate is fixed to the foundation (masonry wall). In this study, similarly to previous work (Vieux-Champagne et al. 2017), the soil-structure interaction is not considered; the numerical model doesn’t include the foundation and its connection to the wooden structure. As illustrated in Figure 6, the posts are connected to this beam with a steel strip which clasps the beam and which is then fixed to the post with eight nails (3 mm × 70 mm).
