As I start a new year I like to take a moment to reflect on 2012. Something that caught my attention in 2012 was the number of calls I was getting from builders and designers who are considering projects using Passive House design criteria.
While the Passive House concept is not new having been developed in Germany in 1990, I can’t say that I recall this level of interest prior to 2012. The name Passive House presents an image of residential construction but these design concepts are also used in commercial and institutional construction. While there is a sophisticated matrix of construction methods and systems that can be used to meet Passive House criteria there are three key aspects to a Passive House design:
1. Increased insulation
2. Sealing air leaks
3. Eliminating thermal bridging
R-Control SIPs are the perfect construction method to meet those three design keys for wall and roof construction whether in residential or commercial buildings. With R-Control Structural Insulated Panels (SIPs) you can achieve whole wall and roof R-values in excess of 44. When using R-Control SIP tape and Do-All Ply sealants you create a very air tight structure. Tests show R-Control SIPs have air leakage less than 10% of that of typical stick construction.
R-Control Structural Insulated Panels provide a continuous insulation envelope. The use of splines instead of conventional framing eliminates thermal bridging. Beyond these three key aspects of building envelope design R-Control SIPs have other advantages including life cycle benefits, strength, and a more comfortable interior environment.
