exterior wall sandwich eps/xps magnesium oxide sip panel
Product Description
MgO Sandwich panel is a composite building material. They consist of a sandwich of two layers of structural board with an insulating foam in between. Panel skins are magnesium oxide boards. Insulation core can be Expanded Polystyrene(EPS), Extruded Polystyrene(XPS).
Compose : MgO (Magnesuim oxide ) Board +EPS/XPS +MgO (Magnesuim oxide ) Board

Usage:
SIPs are prefabricated systems used primarily for walls and roofs. SIPs employ composite materials, reduce waste through modular construction methods, achieve high insulation values, and may be used instead of many conventional building methods.
Comparsion of Core:
Core | Advantage | Disadvantage |
Polyurethane | The main advantage of polyurethane (or the much harder to pronounce derivation, polyisicyanurate) is that it has the highest R-value of any SIP panel. After what's called thermal drift, it's about 6 to 6.8 of R-value per inch of panel. | The main detractor of urethane panels is the high cost. The other disadvantage in terms of construction is that polyurethane has a high melting point, hot wire burners (the primary method of modifying EPS and XPS panels on site) can't be used. |
EPS | Over 80% of the SIP panels installed are EPS. EPS core material is widely available. It is easy to modify on sight and most sip installers have experience dealing with EPS. It's also the least expensive option in terms of material cost. | |
XPS | XPS has many of the best characteristics of both polyurethane and EPS. It has a high R-value (5 R-value per inch of panel). It is dense and stable yet has a relatively low melting point so on-site modifications are as easy as EPS. Also, like EPS, it bonds easily to OSB and gypsum board. | Unfortunately XPS is expensive and manufactured panels are not widely available |
