Appliances

Siltherm’s advanced microporous thermal insulation products deliver exceptional energy efficiency, safety, and compact performance for a wide range of domestic appliances. Engineered using high‑performance silica‑based cores and innovative vacuum insulation technologies, Siltherm solutions help manufacturers create appliances that are more energy‑efficient, safer to operate, and longer‑lasting.

Domestic Appliances 

Siltherm produces one of the industry’s most extensive ranges of high and low‑temperature microporous insulation solutions, suitable for numerous domestic applications. Their products are lightweight, space‑saving, and designed to significantly reduce heat loss—making them a powerful alternative to traditional insulation materials such as calcium silicate, fibre blankets, and vermiculite boards.

  • Superior thermal performance: Microporous structures minimise heat transfer, dramatically improving insulation efficiency.
  • Energy savings: Reduced heat loss decreases energy consumption and supports appliance manufacturers in meeting modern efficiency standards.
  • Compact and lightweight: Thin, high‑performance panels enable slimmer appliance designs without compromising performance.
  • Durable and reliable: High thermal stability, reduced casing corrosion, and long service life contribute to lower maintenance requirements.

Domestic Storage Heaters

Storage heaters depend on effective heat retention, and Siltherm’s microporous insulation materials are engineered to maximise thermal efficiency. Their rigid and flexible panel solutions – such as Siltherm Board, Siltherm Board 3D, Siltherm Panel, and SlatFlex – provide consistently high insulation performance while being easy to integrate into heater assemblies.

How Siltherm Improves Storage Heaters

  • Enhanced heat retention: Ultra‑low thermal conductivity reduces heat loss, allowing heaters to store warmth for longer periods.
  • Improved energy efficiency: Better heat retention results in reduced pre‑heat cycles and lower daily energy consumption.
  • Safer operation: Lower outer‑casing temperatures help create safer household environments.
  • Longer-lasting components: Reduced thermal stress minimises casing deterioration and helps extend appliance lifespan.

Domestic Refrigerators

Refrigerators require highly efficient low‑temperature insulation to keep internal temperatures stable while minimising energy use. Siltherm’s Vacuum Insulation Panels (VacuPanel/VIP) offer exceptional thermal performance thanks to a microporous silica core sealed within a multi‑layer, low‑permeability barrier film.

Why Siltherm VIPs are Ideal for Refrigerators

  • Outstanding low‑temperature insulation: VIPs deliver significantly higher insulation performance compared to traditional foams.
  • Space-saving design: Ultra‑thin panels maximise interior storage volume without increasing external size.
  • Energy-efficient operation: Reduced heat transfer helps refrigerators maintain internal temperatures using less energy.
  • Reliable performance: Robust construction ensures long‑term stability in demanding cold‑chain and domestic refrigeration environments.
