Yes, thermal expansion significantly impacts the performance of vinyl windows, particularly in high-altitude environments like Colorado. Because vinyl is composed of pure PVC resin, it experiences significant expansion and contraction during the extreme temperature shifts common at high altitudes.
This movement can lead to several performance issues over time:
- Seal Compromise: The greater thermal movement of vinyl can loosen perimeter seals, which allows for drafts and moisture infiltration.
- Structural Risks: If not installed with exacting care, this expansion can lead to frame warping and seal failure. In extreme cold, vinyl may also become brittle and prone to cracking.
- Maintenance Demands: While vinyl is generally low-maintenance, its tendency to bow or distort under intense sun exposure can affect its long-term durability compared to more stable materials.
In contrast, composite materials like Fibrex are specifically recommended for high-altitude projects (above 5,000 feet) because they offer much lower thermal expansion. This stability helps maintain the window’s structural integrity and seal performance through freeze-thaw cycles and intense UV radiation.
