Thermal regulating building materials and other construction components containing polymeric phase change materials

A material for energy management and peak energy reduction in a building structure, comprising:

• a loose fill inorganic insulative base material;
• a reflective barrier portion;
• a microencapsulated phase change material;
• and
• a functional polymeric phase change material that dynamically absorbs and releases heat to adjust heat transfer at or within a temperature stabilizing range and having at least one phase change temperature in the range between −10° C. and 100° C. and a phase change enthalpy of at least 5 Joules per gram, the functional polymeric phase change material including a plurality of polymer chains, the plurality of polymer chains including a backbone chain and a plurality of side chains, wherein a first portion of the plurality of polymer chains are crosslinked to each other, wherein a second portion of the plurality of polymer chains are crosslinked with the microencapsulated phase change material and a third portion of the plurality of side chains are mechanically entangled with the loose fill inorganic insulative base material.
