Product Overview
—Ultra-lightweight Loose Fill Sand for Energy-Saving Kiln Car Bases
Product Overview
ThermoLite Kiln Car Sand (TKS) is a very light, loose-fill insulation made for high-heat use, especially in kiln car bases. It is built to replace older insulation materials like ceramic fiber, vermiculite, and perlite. TKS gives better heat insulation, stays stable over time, and helps save energy. Its granular shape makes it easy to handle, fill, and reuse, giving steady results for years.
Key Features
- Very lightweight – Low weight helps reduce the load of kiln cars, saving energy
- Good heat insulation – Keeps more heat inside and boosts kiln efficiency
- Stays stable – Keeps working well even after long use at high heat
- Easy to use – Free-flowing grains make it fast to fill tight or odd-shaped spaces
- Saves energy – Cuts down fuel use and lowers both costs and emissions
- Reusable – Can be used again after kiln car work, reducing waste
Typical Uses
ThermoLite Kiln Car Sand (TKS) works well in many high-heat jobs, like:
- Ceramic making – Used under kiln cars for tiles, bricks, and bathroom ware
- Refractories – Fills space in furnaces and kilns needing heat control
- Industrial ceramics – Keeps heat in during firing and sintering
- Building materials – Used in high-temp kilns for making cement, blocks, etc.
Main Benefits
- Saves money – Uses less energy, cuts running costs
- Safe and clean – No harmful fiber, easy to dispose of
- Strong in heat – Holds up over time at high temperatures
- Works anywhere – Fits many furnace and kiln designs
