Recently we had a call from a builder complaining that their roof sheathing was buckling, causing a telegraphing effect through their roofing shingles. Concerned about the structural efficacy of the roof, they asked us to take a look. The builder and dealer thought it was a number of problems with the roofing panels themselves but, on closer inspection, we discovered that there were a number of installation issues that caused the problem.
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.
Nails literally hold the world together, but just how much do you know about your fasteners? Do you use the same nails for every job out of habit? Always ask your design professional to stipulate sizes and fastener patterns, but knowing what kind of nails to use may save you time and money on work that lasts.
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.
Despite code restrictions on supply ducting in building cavities, they are regularly utilized for return ducting. However, this practice compromises your building envelope and leads to leaks. When return-air plenums are installed, it results in energy loss, an increase in energy bills and a less efficient HVAC system.
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.
