Greenix Polyurethane vs EPS SIPs

Greenix Polyurethane vs EPS SIPs

Over the years we’ve had numerous questions regarding the difference in our Greenix Polyurethane vs EPS SIPs Panels.  Below is a comparison chart that points out the differences between the two types. When comparing prices, be sure to include the extra labor/hours required during installation when using EPS Panels, as they require on-site alterations to create the panel connections and routing and framing for the doors, windows and eletrical box openings.   We prefer to manufacture panels that are ready to go once delivered with no more effort than fitting the panels together.
