SIPs Framed Structures Are Now Less Than Stick Framing

As Timber costs have escalated, higher-end panelised framing options (such as SMART SIPs) are now more cost-effective than traditional 2×6 stick-framed structures. SIPs also offer proven stronger, straighter, and greener benefits over stick-framed structures.

As building energy, codes change and traditional framing methods will no longer qualify alone, when building high-performance homes, Structural Insulated Panel Systems easily help building owners, designers and builders achieve new high-performance requirements.  


When trying to maintain a budget and uncertainty on rising Timber material costs, now is the time for builders and architects to make the move to SIPs construction


It’s the right thing to do for your budget and for the planet.

Smart SIPs OSB Panels are fully Prefabricated  and all Timber Splines, OSB Splines, Top Plates, Bottom Plates, and Lintels are  included with our supply when using our OSB and Cement SIPs panels

We can supply a range of materials for your SIPs panels 
The Skin material options are OSB, MgO, or Cement Sheet and are subject to building design and engineering

Smart SIPs  Core Options 
Smart SIPs Has A Range Of Core Material Based On Your Building Design And Performance You are Looking to Achieve. 
See The List Below 

Core Material 


Graphite filled EPS (GPS) (Neopor by BASF) 

BASF Neopor® GPS is a graphite polystyrene (GPS) rigid foam insulation that gives maximum efficiency, cost-effectiveness and sustainability on construction projects. Planners, architects, contractors and builder-owners benefit from insulation made of Neopor GPS because of the special advantages this material offers. Silver-Grey Neopor GPS is comprised of many small pockets of air within a polymer matrix containing graphite.

The graphite reflects radiant heat energy like a mirror, increasing the material's resistance to the flow of heat, or R-value. Most polymer-based foams exhibit a greater ability to slow the movement of heat as the temperature decreases.  Neopor GPS is in a unique class because it increases in R-value as the temperature outside drops. 

With a R Value of 1 per 25mm of panel.

GPS is also  an affordable option to using 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.  With a R Value of 0.63 per 25mm of panel


XPS has many of the best characteristics of both polyurethane and EPS. It has a high R-value (1 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. However, it is much more costly.


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 1.2 to 1.36 of R-value per inch of panel. However it is much more costly and more difficult to work with.
