Wagner FURNO 500 Variable-Temperature Heat Gun for Window Restoration

What it is: The Wagner FURNO 500 is a variable-temperature, 1,500-watt heat gun selected for controlled paint and glazing-putty removal during historic window and door restoration.

Why this model: Twelve temperature settings from 150°F to 1,200°F provide more control than a basic two-temperature gun. The included glass-protector nozzle helps direct heat away from adjacent glass, and the flare nozzle spreads heat across broader painted surfaces.

Used for: Softening failed paint, caulk, adhesives, and old glazing putty before careful mechanical removal.

• 12 temperature settings: 150°F–1,200°F
• Two fan settings plus cool-down mode
• 1,500 watts / 5,100 BTUs
• Graphic LED display with push-button controls
• Includes glass-protector and flare nozzles
• Integrated stand for hands-free cooling

Historic-window caution: Begin with the lowest effective temperature. Protect the glass, avoid prolonged heat in one spot, and do not use on insulated or laminated glazing where heat can damage seals or crack the glass. Heat may also soften sound glazing putty that you intended to preserve.

Classic Door confirmation: If you are unsure whether heat is appropriate for your sash, glass, paint system, or glazing condition, send photos before ordering.
