Increased incidence of strong weather systems and the tragedies that follow high wind events have encouraged engineers and designers to rethink the way we build to improve wall strength. Stronger walls will keep home occupants safer during weather events and will increase the lifespan of the home. One of the problems is that the roof, wall and flooring systems are installed as separate entities. Connecting the OSB wall sheathing and the flooring system can create a continuous load path which can improve wall strength by up to 38%.
The APA (the Engineered Woo Association) recommends that construction professionals leave a 1/8-inch gap between each panel edge and end joint. As ambient moisture changes, your OSB or plywood panels will expand and contract. When you butt the panels together tightly, there is no room for expansion and this can cause buckling in the panels. …
As rebuilding efforts commence in the wake of this summer’s storms, construction professionals seek ways to ensure that homes are safer and built to withstand major wind events. There are several techniques that will help to keep property and lives safe.
Moisture can cause many structural problems and create a very unhealthy home for your family when mold and mildew begin to form. Building a home that deals effectively with moisture requires due diligence from design to installation and on to maintenance. The home must be built in such a way as to prevent leaks which are the biggest cause of damage and it must also eliminate condensation which occurs naturally in every home.
Raised-heel trusses provide a cost-effective way to meet more stringent energy efficiency codes. It’s not surprising that four out of five modern homes are built with pre-fabricated trusses as they offer a lot of advantages; a more uniform pitch and size, increased spans mean fewer internal load-bearing walls and they can be installed quickly, with less labor.
One way to work smarter is to build using raised-heel trusses. From the APA: “Also known as energy-heel trusses, raised-heel trusses deliver cost-effective energy performance especially when combined with continuous plywood or OSB sheathing.”
As the cost of building materials increase and building codes demand more effective envelopes, construction professionals are looking to taller wall sheathing to fill in the gaps. OSB wall sheathing already makes for a sustainable and cost-effective option but with taller OSB wall panels, the efficacy of the building envelope is increased by creating fewer seams while labor costs, waste and installation time are reduced.
