Both the International Building Code (IBC) and International Residential Code (IRC) have sections describing the minimum R-value of spray foam needed to effectively manage condensation risk in walls and ceilings as part of a hybrid system.
The product's high R-value, environmental features, plus fire and smoke performance caught the attention of Harley, Ontario-based Stubbe's Precast Commercial.
At this stage, correlation between glucose and insulin became negative with significant p-value in all diabetic groups (r-value -0.905, p-value 0.013).

After 45min post mortem, the initial pH ([pH.sub.45min]) and the R-value were determined in the Longissimus thoracis muscle between the 9th and 10th ribs.
This is important to members of the nonwovens industry who are involved in the manufacture and/or supply of any sort of home insulation product because, as FTC notes, the R-value Rule covers all products that are "mainly used to slow down heat flow." The current rule, in fact, covers most types and forms of insulation marketed for use in residential structures, even if those products aren't directly cited under the current R-value Rule.
In short, high R-value is no longer the main driver in door selection.
High-end custom fabric designs withstand wind and snow loads, and can be insulated to any R-value without exorbitant cost.
To determine the best structure for the network there is no certain procedure; therefore trial and error is performed and the best network topology is chosen based on correlation coefficient (R-value) and mean square error (MSE) criteria in this study.
A 1.2-m by 2-m by 0.185-m-thick wall section had an apparent thermal conductance of only 0.204 W [m.sup.-2] [K.sup.-1] including the structural wood frame, which is equivalent to a US R-value of 27.9 h [ft.sup.2] [degrees]F [Btu.sup.-1] (3.8 h [ft.sup.2] [degrees]F [Btu.sup.-1] [in..sup.-1] for the 7.3-in.-thick wall section).
Certain insulated Clopay models provide an R-value of 20.
"Typically, the thicker the insulation, the higher the R-value, or resistance to heat gain or loss," explains Roger Borgman, national sales manager.
