        "text": "The best frame material for sliding windows depends on your priorities. Vinyl frames are a popular, cost-effective choice known for their excellent insulation and minimal maintenance.

Wood frames provide a classic aesthetic and good insulation but require more maintenance.

Each material has distinct benefits for performance and aesthetics.",
