Picking SIPs Is Like Picking a Cooler

April 27, 2018

Selecting a structural insulated panel (SIP) and choosing a cooler might seem like unrelated decisions at first glance. However, these two choices actually have more in common than you might think. Let's delve into the world of coolers to draw some parallels.

When it comes to coolers, there are two primary types of insulation used: expanded polystyrene (EPS) and polyurethane foam (PUR). The typical "throw-away" coolers you find in grocery stores are made of EPS, characterized by their plain white appearance and lack of durability.

The top-of-the-line coolers offered by brands like Igloo or YETI utilize polyurethane foam, which sets them apart. These coolers are robust, capable of keeping contents cold for up to seven days. The superior performance of polyurethane foam stems from its enhanced construction properties.

Drawing a connection between coolers and SIPs, we find that SIPs also come in two varieties: EPS and polyurethane. These two types differ significantly in terms of their R-value and fire resistance. EPS foam has an R-value of 3.8 per inch, whereas polyurethane foam boasts a higher R-value of 6.9 per inch. Furthermore, while EPS softens at approximately 180 degrees and melts when exposed to fire, polyurethane-based Thermocore SIPs do not melt. In fact, we enhance the polyurethane foam in our SIPs with a fire-retardant additive to ensure self-extinguishing properties.

When making your SIP selection, consider the analogy of choosing a cooler. Are you willing to settle for an option that may not last as long or perform as effectively? Or would you prefer to invest in a high-quality solution that delivers superior performance and long-term benefits?
