Description
- The present invention relates to modular building panels or structural insulated panels utilized to fabricate the walls, ceilings, floors, etc. of houses, room additions, porches, mudrooms, sheds, outbuildings, and the like.
- The use of modular building panels is a popular method for economically adding additional enclosed structures to a pre-existing structure. Examples of new structures include room additions and enclosed porches. In many cases these room additional enclosures are used for leisure activities such as reading, watching television, and visiting with guests.
- Typically modular building panels cost less than conventional construction materials. Modular building panels may be quickly disposed in an edge to edge configuration to form walls, roofs, etc. The assembly time required to build a structure with modular building panels is typically much less than when building using conventional construction methods. The time and labor savings provides additional cost savings.
- Structures built with modular building panels are often exposed to the wind, sun rain, hail, and even seismic activity. It is desirable that structures built with modular building panels be durable enough to withstand exposure to these elements.
- It is a popular construction technique to design additions to houses that match the style of the existing structure, both internally and externally. It therefore may be desirable for aesthetic or practical reasons to attach other building construction materials to a modular building panel. For example, it may be desirable to attach conventional shingled roofing material or a drop ceiling to a modular building panel to make the addition look more like an integral part of the building, or to provide additional insulation or protection.
- The description pertains to a structural panel that includes five layers sandwiched together. The two outer layers and the central layer may be made from a harder material such as plywood, aluminum or steel. For example, the two outer layers may be made from aluminum and the inner layer may be made from plywood or other wood. The other two inner layers may be made from a lighter, rigid material, such as expanded polystyrene (EPS) foam or other suitable material. Typically, the structural panel also includes ends on two opposite sides designed to interlock with the ends of other structural panels. These interlocking ends may provide a strong mechanical joint that is resistant to water or is weatherproofed.
- The description also pertains to a structural panel that includes seven layers sandwiched together. The two outer layers and the third and fifth layers may be made from a harder material. The other three inner layers (the two layers adjacent the outer layers and the central layer) may be made from a lighter, rigid material such as expanded polystyrene foam. The panel may thus be constructed of alternate layers of a harder material and a lighter, rigid material. The central layer may be made from a honeycomb-type product to provide additional rigidity, sound dampening, or other desired characteristics.
- The description also pertains to a structural insulated panel (SIP). These panels are often constructed of a central foam core sheathed with a structural material such as drywall, plywood, or oriented strand board on each side. The other laminate substitutes for the structural material. The laminate may include a rigid foam core sheathed with a thin skin of harder material such as wood, aluminum or steel. The structural insulated panel can be given additional strength by connecting the laminates with ribs of wood, steel or aluminum through the central foam core.
