Structural Insulated Panels (SIP's) v Timber Frame

When researching the pro's and con's of (Structurally Insulated Panels) SIP panels v timber frame, the information available is hugely biased in favour of the SIP's.

Including the thermal efficiency, what are the other PRO's and CON's? What are peoples opinion on the Durability, Structural Integrity and Moisture Resistance of SIP's.

SIP panel systems have to achieve all sorts of certifications and testing to demonstrate compliance with the New Zealand Building Code (NZBC) which is great, but these are the minimum standards possible to build legally in NZ and we should be striving to exceed.

Please let us know your thoughts.

We must remember: Sustainable Development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. SIP panels made from cruel oil based expanded polystyrene with outer lining panels made from formaldehyde encapsulated OSB. These products do not fit with this very important document. The term Eco and Green Building has empowered a ''cherry picking'' approach to Sustainable Development. What may be considered high R-value or ''speed to build benefit'' products are creeping in when they are in fact a toxic cocktail with zero downstream waste management plan. One million years to break down in landfill. Plastic shopping bags are banned while the building industry adds more and more ESP products to our built environments. Where do we think the waste from hurricane impacted housing around the globe is taken. There are no pro's with SIP panels when the truth is spoken and Sustainable Development is the aim.
