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.
Stringent new building codes require improved efficiency of building envelopes through better insulation. While more expensive insulation methods, like spray foam, may have greater R-values, it is possible to meet the required high R-values using less expensive fibreglass or cellulose insulation with a raised heel truss.
There is a vital difference between Plywood and OSB panels and sheathing that are classified as ‘Exterior’ and ‘Exposure 1’. Utilizing the wrong panels or sheathing could compromise the structure which is exposed to weather. The classifications are based on material composition as well as the durability of the adhesives utilized in the manufacturing process.
Overdriven fasteners can affect the shear capacity. Here are the important things to look for and if necessary corrective actions required as outlined by the APA.
While swelling or buckling of sheathing panels doesn’t affect their performance or strength, it can cause blemishes in the building’s appearance that will lead to callbacks.
Did your wall sheathing get wet? Well, best listen to the Ol’ Sage Builder regarding the maximum moisture content before closing up your walls.
Unventilated attics can help to mitigate energy loss through leaky ducts or ceiling fittings. The energy savings touted by unvented attics can be as high as 20%. However, if moisture is able to enter the unvented attic space, it may lead to roofing panel issues.
When installing structural panels, you should always follow the manufacturer’s instructions. You can also liaise with your design professional and consult The Engineered Wood Association (APA) guide E30V which you can download here. We have included some tips to keep in mind when installing OSB wood structural panels.
Discover how Raised-Heel building trusses can enhance insulation and insulation performance. Improve energy efficiency at home.
The US Formaldehyde Standards for Composite Wood Products Act was signed in 2010. It was based on the Air Toxic Control Measure that was developed by the California Air Resources Board and is commonly referred to as CARB.
