Take a look at this real-live video footage taken on January 11, in Raleigh, NC…when severe thunderstorms hit the area and the extreme wind brought this condo building down to the ground.[youtube=http://www.youtube.com/watch?v=5t9MpNTSbYg&w=560&h=315]
As you see in this video, stick framing is incredibly vulnerable until the sheathing is properly nailed off. A stick framed wall has no resistance to shear until the sheathing is nailed, making it vulnerable to collapse from wind or seismic loads. When structural insulated panels (SIPS) are used as the framing method you have the full sheer strength available immediately as soon as the SIP is installed and nailed to the sill plate, top plate and adjacent panels. Risk less when you build with SIPS.
SIPS are a structural composite…three components working together to provide performance under pressure. This composite assembly yields stiffness, strength, and predictable responses. These three components provide a ‘sandwich’, which is stronger than the individual components.
SIPS provide excellent resistance to axial, flexural and lateral forces that all buildings are subject to. This means that SIPS have the ability to support axial loads in wall applications, provide excellent resistance to lateral loads caused by earthquakes or high winds, and ensure that the roof can support the loading it is subjected to.
DIY network’s Deconstruction show featured Premier SIPS to display just how durable and strong they are. See min 10:47 of the video where they discuss and test SIPS for storm prone areas and hurricane force winds:
Other Benefits of SIPS
SIPS can be used in walls, ceilings, floors and roofs. SIPS provide a high R-value with the benefits of a high strength-to-weight ration among many other benefits such as:
Energy Efficiency and Comfort:
- The energy-efficiency gained from a SIP system can help your building stay cooler in the summer and warmer in the winter without using excessive amounts of natural gas, fuel or electricity.
- Premier SIPS have R-values that range from R-15 to R-45 depending on the thickness of the insulating core. SIP structure typically exceed local energy code requirements.
- Premier SIP systems can help building and home owners pursue green building ratings, certifications, tax credits, and energy-efficient mortgages.
Improved Indoor Air Quality:
- Due to the tightness in construction of SIP systems and the lack of thermal bridging, as is common in traditional stick framing, a SIP building has less air leakage, and is less drafty leading to improved occupant comfort.
Ease of Construction:
- Once the floor slab or foundation is completed, SIP systems can ‘dry-in’ a building within days. SIPS arrive on site with wiring chases pre-installed from the factory.
