Structural insulated panel stem wall slab on grade.

Slab is one foot or less below grade r 10 insulation required extending 2 feet below grade for climate zones 4 and 5 4 feet below grade for climate zone 6 insulation should extend downward from the top of the slab with two options to reduce slab edge insulation r value exterior slab insulation must be protected 46. The first of these is to build a stem wall of concrete blocks up to the desired slab level. Two methods for installing structural insulated panels to a slab on grade foundation are shown. The key difference in this build type is the use of stem walls.

5 panels model amdkit001 56 08 56 08. The foundation would consist of concrete block stem walls extending to a footing below frost line. Note that slab perimeter insulation is of increasing importance with increasing number of heating degree days. Finally a slab is poured to the desired level.

Inside the block walls scaglione will pour a concrete slab floor. Armorwall bg is a below grade factory waterproofed exterior wall sheathing with a ul classified substrate that is a tested high strength fire resistant exterior insulated wall sheathing product that is designed to assist in insulating the slab edge and below grade to above grade transition that is often difficult to construct in the field. Exterior walls would be framed on top of the block walls roughly 24 inches above grade. A net zero house is insulated on all 6 sides and tc legend builds with structural insulated panels sips so we have r 29 sips walls all around r 49 sips roof above and 4 r 20 foam under the slab on grade.

Installing slab insulation during the construction process is more straightforward. For more information on sip manufacturers. For more information on sips see the green building encyclopedia. Then the fill dirt is added and compacted.
