AMSCO Meets the Strictest Standards to Minimize Color Change Over Time.
- Some degree of color change over time is unavoidable and acceptable by industry standards. AMSCO Windows uses only PVC, SuperCap and vinyl that meets the most stringent AAMA (American Architectural Manufacturing Association) and ASTM (American Society for Testing and Materials) standards.
- These standards take into account natural aging and weathering factors and describe the allowable changes in ways that can be scientifically measured.
- In the ASTM standards, the values for acceptable color change are determined on a three-dimensional measure (dark to light, red to green and blue to yellow) and mathematically expressed to allow objective and repeatable standards to be established.
- PVC that passes the AAMA standard for window profiles meets this color change standard.
- Chemicals can cause PVC discoloration. All fuels, solvents, bleaches or corrosive chemicals must be avoided.
- In dry climates with high levels of solar energy, slight color change can be expected in any material and PVC is no exception.
- Color change has no effect on the strength or structural integrity of the PVC.
