An experienced company can confirm the right fit for your house with a quick inspection.

Why Humidity Is the Main Decider

Humidity works into joints, weeps, and frames, and windows are full of these pathways. Wood is hygroscopic, so it swells, and vinyl is hydrophobic, so it does not absorb water, though it expands from heat.
