When selecting window frame materials, a crucial aspect to consider is their durability and thermal performance. Durability is essential because window frames are exposed to various environmental conditions and must withstand wear and tear over time. A durable frame will resist rotting, warping, and corrosion, ensuring a longer lifespan and minimal maintenance issues.

Thermal performance is equally important as it directly affects a building's energy efficiency. Good thermal performance helps in regulating indoor temperatures, reducing heating and cooling costs. Materials with poor insulation values can lead to energy loss, uncomfortable indoor climates, and higher utility bills. Therefore, selecting window frames that offer both durability and optimal thermal performance is vital for a long-lasting, efficient window system, making this the best consideration when evaluating materials for window frames.
