The type of insulation you choose can result in thousands of dollars saved in utility bills over the life of your home. Insulation is rated by R-Value, which measures a material’s thermal resistance. Insulating materials with a higher R-Value correspond with increasingly better performance. However, studies have shown that determined R-Values have little correlation with how an insulating material actually performs in a non-SIP home. When taking into account factors such as cavity voids, wiring without compression, and paper facer stapled to studs, the actual R-Value decreases significantly.SIPS homes avoid these familiar problems by distributing insulation uniformly among the entirety of the panels. Without these negative effects, actual R-Value of insulation within a SIPS panel can actually exceed its determined R-Value.
