Icynene Engineer John Broniek's recent webinar for Buildings Canada looks at the options for various types of commercial and residential assemblies with a view to maximize performance and make them work without excessive cost and problems.
Domaine Vincent Pinard, one of the oldest and most renowned wineries in France’s famed Loire Valley region, became interested in preserving their cellars with spray foam insulation to better regulate the temperatures needed for the wine-making process.
Wind damage during an extreme weather event such as a hurricane can leave significant damage to a building. One particular area susceptible to significant damage is the roof. Water ingress from roof damage is considered one of the most commons insurance claims. One easy solution to address this problem is an unvented roof which is designed around spray foam. This helps protect the roof from damage due to fewer openings, thereby reducing the chance of water penetration.
Spray foam can be a key component of the remediation efforts following extreme weather events such as hurricanes or floods. With these weather events, significant damage can be sustained by buildings, yet the aftermath of hurricane-strength winds and the threat of wind-driven rain and flooding can be addressed with proper planning and understanding.
Using open-cell spray foam can help provide sustainable, high-performance buildings that gives a tremendous return-on-investment over the long term. As well as offering energy efficiency and moisture management, open-cell spray foam insulation can aid in the whole building design. Optimizing building envelope performance considers how all building components interact.
In the immediate aftermath of extreme weather situations such as hurricanes and flooding, it is necessary to assess the extent of the damage, extent of contamination, proper clean up requirements, when rebuilding/repairs can begin and flood resistance design strategies.
It is important, following extreme weather events that cause flooding, to assume that water is almost always contaminated. It may be highly likely that the incoming water contains contaminants such as:
Following an extreme weather event such as hurricane or flooding, assessment of the damage is critical in understanding how to approach the next steps. Once the extent of the damage is determined, removal can begin. It is recommended that a qualified clean-up contractor assess the removals required.
When retrofit work is about to begin, it will be necessary to determine the readiness of insulated assemblies for spray foam. It is most desirable that surfaces be clean and dry to accept spray foam. Wood should have a moisture content of less than 19%. Concrete should be visibly dry and free of residue. Metals should be free of dirt and oil. Any surfaces subjected to flooding should be disinfected and treated to address mold. Residual salt should not impact spray foam.
Building Genius presents architects, commercial builders and production builders with an insight into the spray foam insulation and building industries across the United States and Canada. With a key focus on building science, codes and standards, burgeoning trends, industry development and news, Building Genius offers an outlook from the spray foam insulation industry leader, Icynene, from the perspective of our top engineers, code specialists and industry experts.
