WHAT ARE THE ADVANTAGES TO BUILDING WITH SIPs PANELS?

ADVANTAGES OF SIPs PANELS VS. CONVENTIONAL “STICK” FRAMING

Speed of construction Panels are made in the plant and are shipped to the construction site ready for installation. With the help of a crane or lift, wall sections can be assembled quickly, reducing dry-in time from weeks or months to a matter of days.

Fewer air leaks Unlike conventionally framed walls, SIPs insulated panels don’t have wall cavities and therefore, fewer opportunities for energy losses due to internal convection. Continuous insulation means that SIPs insulated panel houses have much less air infiltration than standard framed houses. However, super tight construction makes whole-house ventilation all the more important. Careful workmanship is key to eliminating potential air leaks at joints between panels — leaks that could cause condensation and structural damage, especially in roof panels.

Reduced thermal bridging Virtually, the entire core is insulation. With dimensional lumber significantly reduced, energy losses due to thermal transfer are lower.

High R-values Standard SIPs insulated panel wall sections are typically up to 6½ inches thick with thicker panels also available. The typical 6½” panel has an R value of 26, making it far superior to 6½” of conventional cellulose insulation that has an R value of 20.

Great strength Bonding the foam core to the outer OSB panels creates a strong assembly, similar to an I-beam. The panels are highly resistant to shear loads (external force that produces sliding failure between two parallel surfaces) and racking (when a building moves out of plumb or alignment). This means that SIPs panels can withstand high winds and seismic activity better than conventionally built stick constuuction.
