Final answer:
Positioning thermal insulation between the deck and the membrane helps limit heat conduction, increases heat transfer, and prevents high temperatures from affecting the membrane's fluidity.
Step-by-step explanation:
Positioning thermal insulation between the deck and the membrane has several characteristics. First, it helps limit the conduction of heat from the inside to the outside during winters and from the outside to the inside during summers. This helps maintain a comfortable temperature inside the building. Second, insulation fills in gaps and increases the contact surface area, which increases heat transfer. Lastly, insulation prevents high temperatures from increasing the fluidity of the membrane, thus maintaining its structural integrity.
