Polyisocyanurate insulation boards offer many benefits that make them an advantageous solution when it comes to designing efficient assemblies. This article lists the 10 main benefits of using polyisocyanurate insulation boards for your commercial roofing projects.
The SOPRASEAL STICK VP self-adhesive vapor permeable air barrier membrane surpasses the products available in the market on several aspects. This article lists 6 reasons that will make you adopt the SOPRASEAL STICK VP compared to its main competitors.
Professional builders know all-too well about the many struggles that can accompany the roof installation process—not to mention the problems that can arise when water damage occurs over time. Poor drainage often leads to water ponding, an unwanted situation that can trigger sagging in flat roofs. Water may also settle into cracks and holes, which can spell trouble when the temperature fluctuates, causing that trapped water to freeze and then thaw.
Do you know what distinguishes these two standards for air barrier assemblies for walls? Some may say that CAN/ULC-S742 is just a Canadian version of ASTM E2357 standard because they have the same test methods. But that is all they have in common. See for youself!
CAN/ULC-S741 and CAN/ULC-S742—published in 2008 and 2011, respectively—are the first Canadian standards related to air barrier materials and assemblies. The first covers air barrier materials, while the second was developed for air barrier assemblies. Read on to discover the 4 main advantages of these standards.
With the cold winter months fast approaching, building professionals will be dreading the additional challenges that plummeting temperatures can bring along with them. One common complaint is that normal outdoor adhesives used for insulation boards, cover panels, and thermal barriers can’t effectively do their jobs in those sub-zero weather conditions we’re all too familiar with.
Published respectively in 2008 and 2011, CAN/ULC-S741 and CAN/ULC-S742 are the first Canadian standards related to air barrier materials and systems. These Canadian standards are specifications. Not only do they indicate how to measure the air leakage of air barrier materials and assemblies but they also include performance requirements. S741 and S742 therefore help designers and specifiers to easily recognize the level of performance provided by air barrier materials and assemblies tested under S741 and S742.
Toronto, Montréal, and Vancouver are all examples of major Canadian cities where space is sometimes restricted on construction sites. In most construction projects located within large urban centres, access to the exterior walls of the foundation is difficult. Under these conditions, a high-performance pre-applied foundation waterproofing system must be used.
Several factors must be taken into account when selecting an air barrier membrane for a wall design. The main purpose of an air barrier is to prevent air leakage through the building envelope. Uncontrolled air circulation can cause heat loss and high resultant energy costs, not to mention increase the risks of condensation and mould growth in the assembly.
When the time comes to think of the roofing of a new building or to make changes to an existing roof, it is important to address the issue of the slope. Whether structural or made of sloped insulation, the slope will ensure adequate water drainage and thus prevent the risks associated with ponding water. This article will help you understand why the insulating slopes are so much appreciated in the market.
Ensuring adequate water flow off a roof is important, both during the construction of a new project or when repairing a low-slope roof. It is therefore important to get the best advice when assessing and designing shop drawings. We listed five benefits of choosing a slope design service like SOPREMA.
Three main steps are required to design a CSA A123.21 roofing system. This article summarizes these steps, in addition to centralizing all resources needed to be able to determine the roofing system that best matches the parameters of your project.
The CSA A123.21-14 standard is a normalized test method of the dynamic wind uplift resistance of membrane roofing systems.
