Insulation Types

While we can laminate any of our insulation types into any of our panel types, it is important to remember that PIR is a weaker core. Therefore, even if you use a structural panel, the PIR core will limit the overall strength of the panel.

 

Expanded Polystyrene (EPS)

Aged R-Value for EPS = 3.8 per inch

EPS SIPs are available in 4′ and 8′ widths with lengths up to 24′.

EPS has the lowest cost per R-Value, which means if you are looking for maximum insulation on the lowest budget, EPS is the choice for you.

EPS core SIPs are the only type of SIP that have been third party tested for structural properties.  EPS can be ordered in thicknesses up to 25″.  EPS is recyclable and does not “out-gas” or loose its insulation value over time by releasing blowing agents.

 

Neopor (NEO)

Aged R-Value for NEO = 4.7 per inch

NEO SIPs are available in 4′ and 8′ widths with lengths up to 24′.

NEO is the new and improved version of EPS, created by the same process with only the addition of graphite, this grey EPS has all the benefits of EPS with a higher R-Value.

NEO is a good choice for structural applications where you want a slightly thinner profile or a higher insulation value. Avaliable in thicknesses up to 25″.  NEO is also slightly less permeable than EPS which lowers the amount of air and water vapor that can migrate through the panel. Our Supplier for NEO is OPCORE.

 

Extruded Polystyrene (XPS)

Aged R-Value for XPS = 5.0 per inch

XPS SIPs are available in 4′ and 8′ widths with lengths up to 24′.

XPS is the best choice when you need a thin strong SIP with a high insulation value. XPS has lower permeability and can be used in any of our SIP products.

While we do not have the third party documentation of its structural properties, our internal testing has proven that it is much stronger than EPS.  XPS cores come in specific thicknesses which can laminated together to create a variety of SIP thicknesses.  3″, 4.5″, 6.5″, 8.25″, 10.25″, and 12.25″ are common XPS SIP thicknesses that we manufacture.

 

Polyisocyanurate (PIR)

R-Value for 1″= 5.7

PIR SIPs are available in 4′ and 8′ widths with lengths up to 24′.

PIR has the highest insulation value, but with limited structural properties it is better suited for applications that don’t require the SIP to handle longer spans and large loads, such as for Timber Frames and Truss Roofs with spans less than 4 feet.

PIR is a great insulator, especially when a thinner profile is specified.  PIR cores come in specific thicknesses which can be laminated together to create a variety of SIP Thicknesses.   3″, 4.5″, 6.5″, 8.25″, 10.25″, and 12.25″ are common PIR SIP thicknesses that we manufacture.
