Structurally Insulated Panel systems (SIPs) are claimed as the ideal solution for sustainable construction in New Zealand, a country prone to earthquakes, extreme weather conditions; a relatively unskilled construction labour force and a desire for more sustainable housing. a simple system of monolithic interlocking insulated panels, SIPs are composed of a sandwich assembly of wood and plastic, with a polyfoam core. this composition is structurally analogous to a wide I-beam, providing structural strength and enabling load-bearing construction, so there is no need for conventional framing. They are prefabricated reducing the overall construction period.
Life Cycle Analysis of SIPs
The exceptional performance of SIPs as an insulator coupled with low air leakage for the built environment offers the construction industry the tools and technology needed to achieve superior thermal performance while making a significant and restorative contribution to the reduction of global warming.
Timelapse of SIPs Construction
A well-built home using SIPs will have a tighter building envelope and the walls will have higher insulating properties, which leads to fewer drafts and a decrease in operating costs. Also, due to the standardized and all-in-one nature of SIPs, construction time can be less than for a frame home, as well as requiring fewer tradesmen.
As a result, the total life-cycle cost of a SIP-constructed building will, in general, be lower than for a conventional framed one—by as much as 40%.
Premier SIPs are a wise investment, both for our environment and for your bank account. Homes built with SIPs offer a significant reduction in utility costs, regularly saving homeowners up to 60% on their utility bills.
When comparing houses side by side, the only factor is the utility bills... who wouldn't choose the house with lower utility bills? Many buyers are willing to pay more for environmental home features such as SIPs. Not only will SIPs lower your utility bills, but they will also improve the resale price of your home.
SIPs are often used in wall construction because they offer improved energy efficiency, strength to the structure, and are prefabricated off site for fast installation. Thermal Shell Homes owner-builder Larry Nelson says that SIPs are just as advantageous in a raised floor system. “The quality of a SIP floor system is higher. It goes together faster and it saves the builder time.”
