50mm Insulation Board — commercial-grade floor insulation for maximum heat retention.
Our 50mm Insulation Board is made from high-heat, commercial-grade calcium silicate, designed to insulate the base of your oven and improve overall heat retention. With greater thickness comes greater insulation, helping the oven retain more heat for longer while also protecting the surface beneath.
Both the Primo and Mezzo are made from an insulating aggregate and will naturally retain heat for well over 4 hours without adding more fuel. Adding 50mm Insulation Board helps take that performance even further, making it the ideal choice if you want stronger insulation and longer retained heat.
If you are planning to build your oven in or want to maximise heat retention through the oven floor, 50mm Insulation Board is the best option. If you want to insulate both the floor and dome of your oven, we would recommend choosing a full Insulation Kit.
