Fiber Cement Skin Panel


 

Alternatives of facing/core materials:

Same characteristic of facing materials: engineered board, such as fiber cement board, MgO Board and plywood. 
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 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
