About Lamit Structural Insulated Panels (SIPs)

Lamit Structural Insulated Panels (SIPs)


Lamit structural insulated panels (SIPs) are high-performance building panels for floors, walls, and roofs. Each panel is made using expanded polystyrene (EPS) interceding two structural skins of oriented strand board (OSB).

Lamit SIPs are as versatile as they are efficient. They can be custom fabricated to your specific project demands. The result is a building system that is very strong, predictable, energy efficient, and cost effective.



Structural insulated panels are high performance building panels used in floors, walls, and roofs for residential and light commercial buildings. SIPs can be custom designed for each home or building. Building with SIPs will save you time, money, and labor.


Ideal insulation and nailbase surface for roofing, walls, and timber frame with T&G wood decking. Nailbase is made of expanded polystyrene (EPS) rigid foam insulation and one outer layer of OSB. These panels typically come in 4'x8' but can go up to 4'x12'.


Whatever your needs may be, the highest quality SIP accessories, which include fasteners, adhesive, tape, and foam, are included.
