Structured insulated panels sips
The most popular choice for structured insulated panels sips is where the two outside layers are made from OSB (oriented strand board). This combination can be used for both exterior construction including roofing but also for floors. The insulating proprieties of the eps (expanded polystyrene foam), at the core of the panel, is a clear benefit in this cost-effective construction choice. You can also consider SIPs with cement board or metal panels on the outside; both still with the reassurance of eps insulation in between.
