Green Building: High-Performance Building Insulation

Where practical, we specify high-performance insulation on our projects to increase the energy-efficiency of the structures.

Icynene open-cell spray foam insulation is one of these products which not only fully fills the wall cavity between the framing, surrounding all the piping and conduit, but also provides an all important air infiltration barrier to reduce heat loss and heat gain.

Structural Insulated Panels (SIPs) are also a very efficient way to create an air-tight and well insulated structure.  They are building panels made with 6" of insulation sandwiched between sheathing.  The panels can be used for walls or roofing.  On our project illustrated here, the underside of the roofing panels was supplied with tongue and groove pine planks which became the finished ceiling of the spaces.
