During January and May, 2009, two configurations of steel-framed walls constructed with conventional 2 × 4 steel studsinsulated with either R-19, approximately 14 cm (5.5 in.) thick, or R-13, approximately 9 cm (3.5 in.) thick, fiberglass insulationbatts were tested in the Oak Ridge National Laboratory (ORNL) guarded hot box using the ASTM Standard C1363 test procedure.The first test wall used conventional 2 × 4 steel studs insulated with 2.5 cm (1 in.) thick foam profiles, called stud-snugglers. Thesestud-snugglers converted the 2 × 4 wall assembly into a 2 × 6 assembly, allowing application of R-19 fiberglass insulation. Thesecond wall tested for comparison was a conventional 2 × 4 steel stud wall using R-13 insulation batts.Furthermore, numerical simulations were performed in order to evaluate the steady-state thermal performance of variouswood- and steel-framed wall assemblies. The effects of adding the stud-snugglers to the wood and steel studs were also investigatednumerically. Different combinations of insulation and framing factor were used in the simulations.
