Project used the MB Rail profile and field cut corners.  EnergyEdge was secured to the top 8″ of the wall form and will remain in place, providing protected insulation at the transition from grade to the wall system. Nicely Done!

The following details illustrate the use of EnergyFlash as a retro-fit flashing material that provides protection to applied insulation material on the exterior of an existing slab or foundation perimeter.

The first detail illustrates a typical installation process and the follow detail is a cross section illustration.  The “ornamental” wood trim material is optional.  The EnergyFlash product is designed to protect a typical 2″ insulation board.  We recommend the use of the DOW “Blue-Board” XPS product because it is approved for below grade installation and has an active insect ingredient.

When using EnergyEdge EE8mb Rail, in order to keep the face of framing material  aligned with outside face of slab, a 2″ offset is required, see detail.

The EnergyEdge EE8mb rail is generally recommended when wall systems require full bearing and/or when exterior finishing material utilize a weep flashing element.

Visit our trench foundation installation video on YouTube.  This installation shows EnergyEdge poured as an integral part of the curb- providing insulation on the exterior side of the foundation/slab edge.

The Commercial Energy Code in Minnesota is based on ASHRAE Standard 90.1-2004 with amendments.(http://www.energycodes.gov/states/state_info.php?stateAB=MN). 

The amendment document  contains table’s addressing  nonresidential, residential and semi heated minimum insulation values for both southern and northern Minnesota climate zones.  They specify R-10 insulation must extend  from the top of the footing if placed on the exterior of the foundation wall or to the top of the slab if the insulation is on the interior side.

In this region, typically we have found that the foundation wall is poured to 100 and the slab is poured on the interior side of the wall.  By using EnergyEdge in the wall form to insulate and protect the top 8″ of otherwise expose insulation, and extending rigid insulation below, where it will typically be protected by grade, current energy codes can be satisfied.

Q:  We were looking to use EnergyEdge FB Rail on our new development.  It is not a slab on grade installation, but will have wood floor trusses-a situation where we want to put the insulation on the exterior of the basement wall to meet Green recommendations. The project will use vinyl siding.  If you have such details that would be appreciated?

A:  EnergyEdge can be used in a basement application and as you have already noted, this will help meet Green recommendations and increase the comfort level of your homes!
