Claims20
A solar heat responsive roofing material comprising:
- a) a continuous phase;
- and
- b) a discontinuous phase dispersed in the continuous phase, the discontinuous phase having a phase transition at a temperature between about 50 degrees Celsius and about 95 degrees Celsius, the discontinuous phase comprising at least one thermoplastic polymer
A solar heat-responsive roofing material comprising:
- a) a bituminous base sheet;
- and
- b) a plurality of roofing granules, the roofing granules including a latent-heat storage material having a phase transition at a temperature between about 50 degrees Celsius and about 95 degrees Celsius, the latent-heat storage material comprising at least one thermoplastic polymer.
A solar heat-responsive roofing material according to claim 15 wherein the phase transition temperature is between about 60 degrees Celsius and about 85 degrees Celsius.
A solar heat-responsive roofing material comprising:
- a) at least one solar-heat reflective material;
- and
- b) at least one latent-heat storage material, the at least one latent-heat storage material having a phase transition at a temperature between about 50 degrees Celsius and about 95 degrees Celsius, the at least one latent-heat storage material comprising a thermoplastic polymer,
- wherein the roofing material includes a continuous phase, and a discontinuous phase dispersed in the continuous phase, the discontinuous phase including the latent-heat storage material.
