Aluminum strips can significantly affect the insulation of a building by reflecting heat and light, reducing the amount of heat that is absorbed by the building's structure. This reflective property helps to keep the interior cooler in summer and can reduce the load on air conditioning systems. However, if not properly insulated, aluminum strips can also lead to heat loss in winter, as they can reflect heat back out of the building. Proper installation with insulation materials can maximize the benefits of aluminum strips in maintaining a comfortable indoor temperature while conserving energy.
