Building SIP Houses

SIPs, short for structural insulated panels, are one of the most thermally efficient methods of construction, and are frequently used to achieve Passivhaus levels of performance. For self builders who want to achieve superior levels of insulation and airtightness, SIPs are the perfect choice. They also have extremely rapid build times, so you can have a short and reliable build schedule compared to other methods of construction like masonry.

Why SIPs?

Structural Insulated Panels (SIPs) aren't only for those wanting to build a Passivhaus; they're well suited to any self build house design and will deliver high dimensional accuracy, unmatched levels of airtightness, and rapid build times. A SIP structure can be erected in a matter of weeks, delivering your self build to a weathertight stage much sooner than other build methods.

Benefits of Building a SIP House

 

  • Excellent thermal performance - Lowering energy bills, with the capacity for Passivhaus performance
  • Slim wall build ups - Unlike with a masonry build, the insulation for a SIPs house is already within the walls, which gives your self build valuable extra floor space
  • Strong - Composite panels are self supporting, and can reach spans up to 7.5 metres long without needing any extra support
  • Fast - Offers some of the fastest build times, capable of erecting a superstructure in only weeks
  • Warm - Our SIP offering features a rigid phenolic urethane core which prevents almost all air leakage, achieving excellent airtightness and virtually eliminating thermal bridging
  • Exceed Building Regulations - In both thermal and fire performance
  • Excellent U-Value range - Meaning the amount of air leaking from your home is minimal, proving its efficiency
  • Factory manufactured - Under strict quality control, ensuring dimensional accuracy and further reducing build time 
  • Sustainably sourced timber - The OSB sandwiching the rigid SIP core is sourced from sustainable forests with indepedent chains of custody that are rigorously checked by FSC and PEFC bodies

Self building is one of the most exciting events in a lifetime, but it requires lots of decisions. What's within the walls is just as important as how they look on the outside.
