Why does an aluminum window frame feel colder to touch when compered to a wooden frame?

An aluminum window frame feels colder to the touch compared to a wooden frame because aluminum is a better conductor of heat. This means that it quickly transfers heat away from your skin, making it feel colder. In contrast, wood is an insulator, which does not conduct heat as efficiently, so it retains warmth and feels more comfortable when touched. Additionally, the thermal conductivity of materials plays a significant role in how they feel to the touch.
