💡 How does a sealed aluminum access door stop moisture damage?

This handy setup blocks water intrusion and cuts down on condensation so your studs and insulation stay dry way longer than basic sheet metal covers ever could.

• Gaskets create an air tight barrier that keeps rain off insulation layers.
• Polystyrene insert acts as vapor barrier to reduce humidity buildup inside cavities.
• Rust proof aluminum skin shields the hole from sun and spray back over years.
