Between the two materials, Fibrex is significantly more resistant to Colorado’s extreme temperature swings than vinyl.
According to the provided content, the primary reasons for Fibrex’s superior performance in the Colorado climate include:
- Lower Thermal Expansion: Fibrex is a wood-fiber and vinyl composite that experiences much less expansion and contraction during freeze-thaw cycles. In contrast, standard vinyl (PVC) has significant thermal movement, which can compromise seal integrity and lead to drafts or moisture over time.
- Dimensional Stability: Fibrex offers excellent dimensional stability, resisting warping, cracking, and distortion better than vinyl in dry, high-altitude climates.
- High-Altitude Durability: At elevations above 5,000 feet, the intense sun and daily temperature fluctuations can make vinyl brittle. Fibrex provides superior UV stability and structural consistency, which helps it meet local building codes for mountain regions.
- Structural Strength: Because Fibrex has higher tensile strength, it maintains its shape and seal better than vinyl, which may bow or warp under intense Colorado sun.
