- as the rolls of heat insulation material are urged along the purlins, dispensing blankets of insulation material between pairs of spaced purlins, with the dispensing of the insulation material controlled so as to form air spaces above the blankets of insulation materials;
- applying layers of radiant barrier material to upper surfaces of the blankets of insulation material with the radiant barrier material received within the air spaces above the blankets of insulation material; and
- applying cross layers of insulation onto the blankets of insulation material, with the air spaces maintained between the blankets of insulation material and the cross layers of insulation and the cross layers of insulation positioned out of engagement with the layers of radiant barrier material.
- 2. The method of claim 1 and wherein the step of applying layers of radiant barrier material on the heat insulation material dispensed from the reels comprises paying out radiant barrier layers from reels of material in response to the movement of the rolls of heat insulation material along the purlins.
- 3. The method of claim 1 and further including the step of mounting sheets of hard metal roofing material to the purlins, with the blankets of insulation material and cross layers of insulation positioned therebeneath.
