A common summer problem is condensation on walls around AC air vents. Moisture is insidious and, once allowed to enter wall structures, can result in damage, mold and mildew. While quick-fix solutions may provide cosmetic relief, it is best to spend the time and money to ensure that moisture is not seeping into your wall structures.
As construction costs increase and building codes demand more effective building envelopes, construction professionals are looking to taller wall panels to fill in the gaps. OSB wall panels already make for a sustainable and cost-effective option but with longer length OSB wall panels, the efficacy of the building envelope is increased by creating fewer seams while costs, waste and installation time are reduced.
Eight strategies for getting the most out of your retrofit budget. Ensure that your home is as energy efficient as your budget will allow by spending your money where it makes the most difference.
Homes built as recently as the 1980s are riddled with gaps in the building envelope and have far too little insulation to measure up to modern energy efficiency standards. Retrofitting an old home will make it more comfortable, will reduce energy costs and will make it kinder on the environment. The question is; where do you get the most bang for your retrofitting buck? Here is a basic guide to help you to decide where your money is best spent.
Raised heel trusses provide additional attic space which allows you to add cheaper batt insulation. This means you increase the efficacy of your building envelope. Throw in some taller wall panels like Windstorm or TallWall and you have a recipe for building envelope brilliance.
An effective building envelope is a combination of insulating building materials and a reduction in air leakage. This reduction can be achieved by using taller wall sheathing panels and through effectively sealing air leaks. When determining which air leaks construction professionals should focus on, Dave Wolf from Owens Corning Science and Technology has conducted a study to see which leaks require the least effort and sealant and provide the highest returns in building envelope efficiency.
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%.
