Structural Insulated Panels (SIPs) are high-performance building materials used in wall, roof and floor for residential
and light commercial constructions. The panels are made by sandwiching a core of rigid foam insulation (EPS, PU,
XPS) between two skins of structural/engineered boards such as OSB, plywood, cement board or magnesium board
etc. The dimension ofQuacent SIPs varies from 1220mm x 2440mm to 2400mm x 7320mm, and its thickness is from
114mm up to 31 Omm, which can meet the structural and insulation demands of all regions.
Quacent SIPs are all manufactured strictly under IS0900J-2015 quality control system. All the lumber, OSB, adhesive
come from Canada or USA with high grade certification.
