Foundations that adjoin frost-protected shallow foundations shall be protected from frost in accordance with Section R403.1.4. * This section requires that foundations that adjoin FPSFs be protected from frost according to the current requirements of Section R403.1.4, which requires that foundations extend below the frost line, be built on solid rock, or use FPSF designs. Each method pre- vents frost from heaving foundations. This language prevents the attachment of FPSFs to reinforced float- ing garage foundations, which may be permitted by some local codes to be placed at shallow depths with- out insulating for frost protection (i.e., the foundation moves up and down with frost).

This section requires that a building with a FPSF be insulated to current FPSF requirements even where an unheated garage or other slab-on-ground is attached to it. The vertical and horizontal insulation must be in accordance with Figure 403.3(3) and Table R403.3(1) and be continuous through the foundation of the unheated structure. The vertical wall insulation must extend between the FPSF and the adjoining slab foun- dation, and any required horizontal insulation must be continuous through any foundation walls adjoining the FPSF. No frost penetration or differential movement occurred with this construction in a HUD demonstra- tion in Fargo, North Dakota. Deep foundations of unheated garages have been attached to hundreds of other buildings built on FPSFs in the U.S. ln most cases the FPSF insulation has been placed continu- ously between the garage floor and the house FPSF; however, the insulation has not been continuous through the foundation walls of the unheated struc- tures. ln these buildings, no differential movement between the deep and shallow foundations has been reported. lnsulation passing through a foundation wall must comply with the requirements of Section R403.3, i.e., it must meet ASTM C57B and the requirements of Table R403.3(1), and the insulation must be of a type that has sufficient compressive strength to carry the load oftf'" building. Alternatively, the building must be oesigned to carry those loads over the insulation and not bear on it. R403.3.1.2 Attachment to heated structure. Where a frost- protected shallow foundation abuts a structure that has a monthlY mean temDerature maintained at a minimum of 64'F(18'C), horizontal insulation and vertical wall insulation shall not be required between the frost-protected shallow founda- uon and the adjoining structure. Where the frost-protected 2015 INTERNATIoNAL RESIDENTIAL coDE@ cOMMENTARY shallow foundation abuts the heated structure, the horizontal insulation and vertical wall insulation shall extend along the adjoining foundation in accordance with Figure R403.3(4) a distance of not less than Dimension A in Table R403.3(1). Exception: Where the frost-protected shallow foundation abuts the heated structure to form an inside corner, vertical insulation extending along the adjoining foundation is not required. * This section stipulates that additions built on FPSFs need not be insulated where they join a heated struc- ture because heat from both structures keeps the ground from freezing. However, where the FPSF abuts the heated building, the horizontal and vertical insula- tion must extend along the adjoining foundation to pre- vent cold from intruding under the slab through the foundation wall. The dimension of the insulation is related to the width of the horizontal insulation. This technique was shown to be effective by the U.S. Army Corps of Engineers Cold Regions Research and Engi- neering Laboratory (CRREL)on a FPSF addition to an airport control tower with a deep foundation in a severe Alaskan climate with a 13-foot (3962 mm) frost line. An abutment at an inside corner is an exception. ln this condition, both the building and the addition heat the ground, and extra insulation is not needed. R403.3.2 Protection of horizontal insulation trelow ground. Horizontal insulation placed less than 12 inches (305 mm) below the ground surface or that portion of horizontal insulation extending outward more than 24 inches (610 mm) from the foundation edge shall be protected against damage by use of a concrete slab or asphalt paving on the ground sur- face directly above the insulation or by cementitious board, plywood rated for below-ground use, or other approvedmate- rials placed below ground, directly above the top surface of the insulation. * This protection for the insulation prevents damage due to excavating (e.9., for landscaping purposes). 4-25
