R-value, the performance marker for how a building envelope material will resist heat flow, plays a critical role in prioritizing a building’s energy efficiency and comfort. To help reduce building energy costs and maintain a comfortable indoor environment, many building designers specify polyisocyanurate (polyiso) insulation in the roof and wall systems. Polyiso has one of the highest R-values per inch compared to other insulation products, including mineral wool insulation. 

Regardless of what industry you’re involved in, a new year always ushers in a crop of new trends. But we’re living in a time of such rapid advancement that it can sometimes feel overwhelming to stay informed on all things “new,” especially when you have a business to run or the next jobsite to get to. That’s why for many in the metal construction industry, attending METALCON is so valuable—it’s like getting a sneak peek into the future. The ultimate trends forecaster, the 2024 METALCON expo (which took place in late fall) was an opportunity to take in the game-changing products and innovations that will influence material and design choices this year.  

When designing an energy-efficient building, one of the most important metrics to consider is R-value— the measure of a material’s resistance to heat flow. R-value is determined through standardized testing methods which help architects, designers and builders compare the effectiveness of various insulating options. Essentially, the higher the R-value of a material, the greater its insulating power.
