THERMAL RESISTANCE MEASUREMENTS AND CALCULATIONS OF AN INSULATED CONCRETE BLOCK WALL.

Author(s) : BURCH D. M.

Summary

THE HOLLOW CONCRETE BLOCK WALL WAS INSULATED BY INSTALLING PARTIAL-SIZE INSERTS COMPOSED OF EXPANDED POLYSTYRENE WITH REFLECTIVE AIR SPACES INTO THE CORES OF THE BLOCKS. THE ISOTHERMAL PLANE METHOD WAS SUBSEQUENTLY USED TO CALCULATE THE THERMAL RESISTANCE OF UNINSULATED CONCRETE BLOCK, CONCRETE BLOCK WITH FULL-SIZE INSULATION INSERTS, AND CONCRETE BLOCK WITH PARTIAL-SIZE INSULATION INSERTS. BOTH WAYS OF INSULATING CONCRETE BLOCK INCREASED THE THERMAL RESISTANCE OF THE UNINSULATED BLOCK BY MORE THAN A FACTOR OF 3. THE USE OF A FULL-SIZE INSULATION INSERT PROVIDED A 10% LARGER THERMAL RESISTANCE THAN A PARTIAL-SIZE INSULATION INSERT WITH REFLECTIVE AIR SPACES.
