TUFF+ INTERLOCK SIP panels consisting of an insulative core sandwiched between two structural facings, used for walls, roofs, and floors, offering a strong, energy-efficient, and cost-effective construction system that does not require wooden studs.<\/p>\n

Structural insulated panels (SIPs) possess high compressive strength in walls due to their sandwich-like construction, which mimics the structure of a steel I-beam. The rigid foam core acts as the web, while the strong outer layers (often OSB) function as flanges, distributing compressive loads evenly and resisting buckling. This design, combined with the strong bond between the core and facers, results in a panel that can handle significant compressive forces.<\/p>\n

I-beam analogy:
SIPs are engineered to behave like an I-beam. The MgO board on the exterior sides act as the flanges, resisting bending and tension, while the foam core provides support and bracing, preventing the flanges from buckling under compression.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

The structural facings used by TUFF+ for walls use MgO (Magnesium Oxide) board skins which are very strong:<\/p>\n
