Benefits The benefits of using SIPs are that they: • provide high strength • have good thermal performance • are suitable for most building designs. Their inherent strength allows them to be used for roof and floor panels, as well as walls. For room-in-the-roof applications they provide well-liked vaulted roof spaces. SIPs provide the capability to span from ridge to eaves with, at most, one intervening horizontal purlin. Thus, simple roof shapes can easily and effectively be covered over in hours – for this reason a SIPs roof is often combined with other build methods. SIPs are also growing in popularity as a wrap-around for structural timber frames, combining this system’s airtightness with the charm of internal exposed beam work. Unlike traditional timber frame, the SIP industry has relied heavily on proprietary code evaluation reports, testing and

accreditations specific to a single approach, many being well-proven since the early 1990s. After various US nonproprietary standards that did not address design properties, in 2009 the US-based Structural Insulated Panels Association partnered with NTA Inc, a product certification agency, to produce the first industry-wide code report. This is available to qualifying SIPA members and the provisions are derived from an engineering design methodology.

Future: ‘Your task is not to foresee the future, but to enable it.’[3] SIPs continue to grow market share and the industry does a good job of promoting itself – ever since Mrs Roosevelt! As well as commercial applications, the system is increasingly well accepted in the self-build market, currently estimated at about 8% market share of the self-build market.5 In addition, SIPs are increasingly used with other building systems as a wrap-around, infill panels and roof panels. >>
