Many contractors have an impression that SIPs are hard to install or are expensive. Someone has given them bad information. Let’s explore the real truth about Structural Insulated Panels.
Expanded Polystyrene (EPS) SIPs account for about 90% of the SIPs market. EPS SIPs is one of the easiest and quickest energy efficient structural systems that is available and code approved in the United States. Notice, I said, “EPS SIPs.” EPS SIPs are easy to install.
What can make installing some types of SIPs more difficult? The difficulty of “field modifications” such as a window opening change. For the EPS SIP, modifying a window opening (example: moving it over 2 inches) is fairly simple. The foam and OSB is easy to cut and move. What makes EPS SIPs so simple is the that the foam is easy to manipulate and cut. Even installing electrical wiring through EPS SIPs is extremely easy. (Click to learn more)
The people that may say SIPs are hard to install are most likely talking about urethane SIPs - the yellowish insulation. Yes, this type of SIPs panel are harder to work with as the insulation is hard to manipulate and modify. Modifying electrical wiring is also very difficult. The bottom line is very few of these Urethane SIPs are sold. It is probably best to stick with EPS SIPs and avoid the hassle.
Finally, what about SIPS being expensive? EPS SIPs are not expensive, most of the time they are misunderstood. (Click and review the five elements of SIPs cost) No other structural energy efficient system on the market is faster to install and more economical. Studies have show that to get the same performance from other systems, many more steps are needed and they are never quite as good.
If you have never tried using SIPs before or it has been a long time, this may be the year that you discover what makes them so impressive.
