Installed faced fiberglass batt insulation with its R-value visible (R-21) [1]. The R-value is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive [2] flow of heat, in the context of construction. [3]
There is no universally agreed definition of superinsulation, but superinsulated buildings typically include: Very high levels of insulation, typically R-40 (RSI-7) walls and R-60 (RSI-10.6) roof, corresponding to SI U-values of 0.15 and 0.1 W/(m 2 ·K) respectively)
R-Value 3.4 – 3.8 (RSI-0.60 – 0.67) per inch (imperial units) Loose fill insulation fills the wall cavity better than batts. Wet-spray applications typically seal even better than dry-spray. Class I fire safety rating; No formaldehyde-based binders; Not made from petrochemicals nor chemicals with a high toxicity
This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.
At a time when most Canadian houses had 4-inch-thick (100 mm) walls with an insulation R-value of r-8, the Saskatchewan Conservation House had 12-inch-thick (300 mm) walls with r-40 insulation and a roof with r-60 insulation, [15] increasing the house's insulation to approximately six times compared to the standard.
All thermal insulation requirements in ASHRAE 90.1 are divided by the climate zone, it means that the amount of insulation needed for a building is determined by which climate zone the building locates. The thermal insulation requirements are shown as R-value and continuous insulation R-value as the second index. [13]

The cellulose insulation lost 26.4% less heat energy over time compared to the fiberglass insulation. It also was shown to tighten the structure more than 30%. [ 8 ] Subsequent real world surveys have cellulose performing 20–30% better at reducing energy used for heating than fiberglass.
