CAN HeatBloc-75 BE USED ON SIDEWALLS?
Yes, but HeatBloc-75 is normally more effective when used under roofs. Roof surfaces are generally much hotter than sidewalls. Up to 80% of the summer heat gain is from above. Low e surfaces become more effective in controlling radiant heat transfer as the temperature of the radiant heat source increases. However, in tropical climates where no insulation is used in sidewalls, HeatBloc-75 can substantially help increase interior comfort levels.
