Thermal performance / Green Building & Sustainable Home Renovation Information & Advice

...thermal metrics: resistance and conductance R-value explained: resistance to heat flow U-value explained: rate of heat transfer Key differences: material vs. assembly performance Regional differences: metric, imperial, and building codes Thermal bridging and effective u-value The two sides of thermal metrics: resista...

...performance is temperature-dependent and subject to thermal drift. Effective R-Value and thermal bridging For professionals, the material’s performance is only half the story; the effective R-value of the entire wall or roof assembly is the true measure. Since GPS is often used for continuous exterior insulation (CI...

...thermal performance. This is in contrast to traditional stucco, which is simply a cement-based plaster.   The key to EIFS's effectiveness lies in its 'outboard' insulation. By placing the insulation on the exterior of the structural wall, it creates a thermal break, preventing thermal bridging through the framing studs...

...performance home builders in the USA have proposed the following rule of thumb: The R-value of insulation installed in a green building should be about twice the code minimum for optimum performance. That is, of course, just a general guide rather than a hard-and-fast rule. Read on and we will explain...  What is the r...
