More and more New Zealanders are recognising the benefits of sustainable houses. That means the design elements that make them so effective are becoming more popular as well.
One such design element is SIPs, an innovative way to build the floor, roof, and walls of a home in a way that minimises both labour costs and build times and maximises energy efficiency. To learn more about SIPs and how they can be used as a vital element within a high-performance home, read on.
What are SIPs?
SIPs, or Structural Insulated Panels, are high-performance, thermally efficient composite panels, in which an insulating layer of polystyrene is sandwiched between two layers of structural strand board. This alternative build material offers a new way to construct the building envelope—walls, roof, and floors—for residential and commercial buildings.
Our SIPs are made and cut by Formance in Christchurch, and Craft Homes is one of only four preferred installers in Auckland.
The Difference Between SIPs and Stick Framing
Traditionally, homes have long been built with stick framing, or frame and truss, but SIPs offer major advantages in a range of important categories, including:
The role SIPs play in prefabricated homes
Energy efficiency is where SIPs really shine. Stick framing doesn’t offer insulation for the building; insulation must be added—and the building envelope made airtight—after the frame is constructed, but SIPs are solid panels with built-in insulation. SIPs have no gaps in their insulation, and offer much superior air tightness compared with stick framing, with up to 90% less air leakage than standard frames.
Because they’re cut to spec at the factory and delivered to the site ready for installation, SIPs also cut down on the amount of construction material waste a building produces. Additionally, they can be custom-made for the climate you live in, incorporating various thicknesses and types of foam based on average temperature and humidity levels.
Craft Homes is one of New Zealand’s very few passive house builders with experience and expertise in SIPs. We’ll work with you to ensure that every element of your new home is built to peak performance. Contact Craft Homes today to book your free consultation.
