Heat transmission coefficients for walls, roofs, ceilings, and floors

Single source of measured and verified-by-calculation, steady-state, thermal transmission coefficients or U-factors for many typical building components. Save time because much of the work of calculation U-factors for a variety of walls, roofs, and floor sections has already been done. Includes 36 walls and 11 roofs for residential and 76 walls, 11 roofs, and 2 floors for commercial buildings. Dual units of measurement.
