Insulated Proofer

Insulated proofers have fiberglass or foam insulation built inside the walls, which prevents heat loss.

The added insulation makes this type of proofer more expensive than uninsulated proofers. However, since they get warmer faster and stay warmer longer, they can save you money in the long run.

In cold conditions an insulated proof-box creates a steady environment for the donuts to proof. This consistency of environment saves time and money.
