Solid Core Home Building
What is a solid core home?
Structural insulated panels (SIPs) are high performance building panels used in floors, walls, and roofs for residential and light commercial buildings. The panels are made by sandwiching a core of rigid foam plastic insulation between two structural skins of oriented strand board (OSB), or plywood.
SIPs are manufactured under factory controlled conditions and can be custom designed for each home. The result is a building system that is extremely strong, energy efficient, and cost effective. SIPS walls are are up to 15 times more airtight than stud walls.
A study by the Oak Ridge National Labs (ORNL) proves that a 4-inch structural insulated panel wall outperforms 2″x4″ stick and batt construction, and even edges out 2″x6″ construction in terms of thermal performance. Structural insulated panels are the structural elements, there are no studs or braces to cause breaks in the insulation. The end result is a more comfortable, energy efficient structure that performs up to spec in real world conditions.
Advantages of EPS Solid Core Panels
- The EPS (Expanded polystyrene) insulation is solid and does not allow air movement.
- The solid core resists water whereas batt insulation absorbs water.
- The stick frame has framing thermal shorts but Structural Insulated Panels don’t.
- The closed cell panel prevents dust and allergens from penetrating the building.
- Framing insulation and sheathing are combined into one panel allowing faster construction.
- Larger clear spans can be designed over stick-built projects. The panel loads are distributed over the entire panel due to the continuous bond between the sheathing and rigid insulation. Eighty foot clear spans with freedom of design are easily accomplished.
