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.
E. Alternatives of facing/core materials:
Same characteristic of facing materials: engineered board, such as
fiber cement board, MgO Board and plywood.Â
Sandwich insulating core: PU or XPS.
Comparison of SIPs made by different facing & core materials:

Facing | Advantage |
OSB | lighter, much easier to be cut, moved and decorated. OSB is made of renewable wood resources, it\'s green. |
Fiber Cement Board | Fiber cement is stronger, both water& fire proof, and termite resistant which is suitable for tropical area where is hot, very humidity. |
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 *0% 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. | Â |
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 |
Our SIP\'s System provides wall and roof assemblies with higher overall (effective) thermal resistance (R-value) than other conventional construction methods. The overall R-value of a building assembly includes the effect of thermal bridges as a result of framing members and is a measure of its ability to resist heat flow through it. The higher the overall R-value of a building assembly, the lower the long-term energy costs will be for heating and cooling.
The table below provides typical R-Values of SIPs in different thickness:
Â
The combined high overall R-Value and low air leakage characteristic of buildings built with our SIP System results in significantly lower energy costs versus other construction methods such as wood frame construction.
