To prevent your house siding from getting hot behind the grill, you can use a heat-resistant barrier. Here are some options you can consider:
Grill Mats: Heat-resistant grill mats are designed to protect surfaces from heat and stains. They are typically made of materials like PTFE (polytetrafluoroethylene) and can handle high temperatures.
Fire-Resistant Rigid Backer Board: You can install a fire-resistant rigid backer board made of cement or other non-combustible materials between the grill and your siding. This will act as a barrier and protect the siding from direct heat.
Heat Shield/Heat Reflective Material: Some heat shield or heat reflective materials are designed to protect surfaces from extreme heat. You can install these materials between the grill and your house siding.
Brick or Stone Barrier: Building a small brick or stone wall behind the grill can create a heat-resistant barrier and add a decorative touch to your grilling area.
Ventilation: Ensure there is enough ventilation behind the grill to dissipate heat. Proper airflow can help prevent excessive heat buildup on the siding.
Keep Grill at a Safe Distance: Position your grill at a safe distance from the house siding. Follow the manufacturer's guidelines for the recommended clearance distance from combustible materials.
Remember that safety is essential when dealing with high temperatures and grills. Always follow the manufacturer's instructions for your grill and any additional accessories you use to protect your siding. Regularly inspect the area behind the grill for any signs of damage or wear on the protective barrier, and replace it if necessary.
