What Texas Sun Does To Vinyl Over Time

The biggest issue in Texas is not just heat, it is repeated heat and cooling cycles.
Over time, lower-grade vinyl can become brittle, discolor, or warp slightly.
Sunlight does not only affect the frame itself, it can also age the gaskets, sealants, and vinyl accessories around it.
South- and west-facing windows usually age the fastest because they take the most direct afternoon sun.
