Between steel,glass fibre,wood,air,copper ,which material is suitable to use as ceiling insulation that keeps a home cool in summer and warm in winter? And why?

Glass fibre is the most suitable material to use as ceiling insulation to keep a home cool in summer and warm in winter. This is because glass fibre has excellent thermal insulation properties, meaning it can effectively prevent heat transfer between the interior and exterior of a building. It is also non-combustible and resistant to moisture, making it a durable and long-lasting option for ceiling insulation. Additionally, glass fibre is lightweight and easy to install, making it a practical choice for homeowners looking to improve the energy efficiency of their home.

Glass Fibre

Glass fibre is the most suitable material for ceiling insulation that keeps a home cool in summer and warm in winter due to its:

- Low Thermal Conductivity: It has a low thermal conductivity, meaning it resists the transfer of heat. This prevents heat from entering the home during summer and escaping during winter.
- High Specific Heat Capacity: It has a high specific heat capacity, meaning it takes a lot of heat to raise its temperature. This helps to stabilize the indoor temperature by absorbing and releasing heat slowly.
- Non-Combustible: Glass fibre is non-combustible, making it safe for use in building construction.
- Lightweight and Flexible: It is lightweight and flexible, making it easy to install and work with.

Comparison with Other Materials:

- Steel: Steel has a high thermal conductivity, making it unsuitable for insulation as it easily transfers heat.
- Wood: Wood has a moderate thermal conductivity compared to glass fibre but is less effective in regulating indoor temperatures.
- Air: Air has a high thermal conductivity and is therefore not a good insulator on its own.
- Copper: Copper has a high thermal conductivity, like steel, and is not suitable as an insulator.
