• Silicone, acrylic latex caulk and/or low expanding foam for air sealing
• High-temperature (heat-resistant) caulk for sealing around flues and chimneys
• Foam board insulation to cover soffits, open walls, and larger holes. Alternatively, you can use drywall or pieces of plywood
• Roll of 14-inch aluminum flashing to keep insulation away from the flue pipe
• Weather-stripping for attic hatch

• The attic must be accessible and easy to move around in
• Use proper safety equipment (dust masks, gloves, long sleeves, safety glasses, lights)
• Attics can get dangerously hot on sunny days, especially in the summer. Make sure there is a friend or family member that can help if needed
• Call a professional if you see any of these:
• Damp conditions indicating a moisture or ventilation problem
• Old (knob and tube) or faulty electrical wiring
• Vermiculite insulation—usually appears as gray, silvery chips
