A wall is made up of the following materials: Plasterboard (R=0.2),4 inches of fiberglass (R=3.96 /inch), Plywood (R=0.9), and Wood Siding (R=0.84). This wall is 11 feet long and 8 feet high. On a particular day the average outside temperature is 34 degrees F. What is the R- value that you would use to calculate the heat loss? (Answer to 2 d.p.) (3 points) Recall that Heat loss =( Temp Diff * A Area) /R-value (Units: BTU/h).
