Insulspan SIPs

General Description

Structural insulated panels (or SIPs, as they are commonly called) are composed of a continuous core of rigid expanded polystyrene foam insulation which is laminated between two layers of structural board with an industrial adhesive at controlled pressure to form a single, solid panel. The strength of this adhesive makes these panels structurally analogous to an I-beam, with the boards functioning as the flanges and the insulating core as the web. The panels can be pre-cut and custom fabricated, and are quickly assembled on-site by fitting splines into pre-routed grooves in the panel edges to form virtually any wall or roof configuration. The result is a simple, fast, highly efficient structural system which provides superior thermal performance and substantially greater strength than conventional stud construction. SIPs provide builders and homeowners with energy efficiency, superior structural integrity, and an easy to install building system. Replacing traditional 'stick built' construction, SIPs are easy to work with and versatile for exterior walls, roofs, floors and additions.
