Structural Insulated Panels known as SIPs is a modern advancement on the timber frame concept. Each individual panel is constructed from two pieces of Orientated Stranded Board (OSB), with a layer of high-grade insulation sandwiched between. The high-performing result is flexible and strong, ideal for many types of projects.
SIPs systems are particularly popular in passive house projects. As its excellent levels of energy efficiency meet the standards required to meet the rigorous Passivhaus certification.
Positives: Ecologically friendly project with a quick build time once panels are on-site. The structure can be erected within days. A passive house can be an ambitious build but does creates an energy-efficient home. Its high performance is due to a number of factors:
- Mechanical ventilation and heat recovery system (MVHR) used in passive house builds
- Near complete airtightness
- Extremely high insulation levels
- Passive house design features, to optimise solar gains and natural lighting
You can achieve passive house certification with a variety of construction methods. Including timber frame home, SIPs and traditional brick and block. The standards for certification are rigorous and could be a challenge to meet.
Positives: It’s an ecologically friendly method with a low carbon footprint. It also makes for a healthy living environment.
