Yes, it’s that time of year again….when a certain chill fills the air, making your teeth chatter and your cheeks burn as you hurry home from the office. Maybe the chilly weather fills your head with thoughts of ski slopes or holiday traditions…or maybe it starts you dreaming of warm, sandy beaches far away from the cold.
Ever hear that dry crackle or feel the effect of static electricity as you remove your coat or sweater in the middle of winter? Maybe have dry itchy skin, cracked lips, or even nose bleeds? Why is it that we associate these things with cold weather like we associate holidays and fruitcake? In one word, humidity.
This may be a bit Engi-nerdish, but as an engineer, one thing I appreciate is good data communicated in a clear, concise way. If you want to understand the problem of thermal bridging at balconies and exposed slab edges and how design choices impact building performance and cost, then I recommend taking a look at this series of reports by RDH, a consulting firm specializing in building science.
The architect’s goal is to create a beautiful building that functions well over the life of the structure and is within the developer’s budget. Our experience has been that when architects realize there is a good solution for the thermal bridging problems on the building envelope, they want to use it. However, one question that often comes up when discussing the benefits and value added by using Isokorb structural thermal breaks is: Can Isokorb® be used at balconies with post-tensioned (PT) slabs?
