The Skogar® Range
Four grades built on the same silica aerogel composite platform — from ultra-thin rigid sheets to flexible and semi-rigid high-temperature barriers.
Skogar® ST
Glass fiber substrate
Rigid sheets starting at 0.5 mm. Up to 1100 °C. UL94 V-0. The grade for tight spaces and rigid integration — battery inter-cell barriers, electronics housings, thin-profile insulation.
Skogar® HT
Preox fiber substrate
Flexible sheets available from 2.0 to 6.0 mm. Up to 1300 °C. UL94 V-0 + FAR 25.853. A versatile grade for aerospace and defense insulation and fire protection.
Skogar® VHT & UHT
Silica or ceramic fiber substrate
Semi-rigid sheets for the highest temperatures. VHT up to 1400 °C (2.0/3.0 mm, silica fiber), UHT up to 1700 °C (4.5/6.5 mm, ceramic fiber). Both FAR 25.853 certified. For propulsion systems, re-entry, and other extreme thermal zones.

¹ UL94 V-0 applies to thicknesses ≥ 1.0 mm, so the 0.5 mm variant is tested to ISO 3795.
Forms & Customisation
Skogar® is available as standard sheets — and adapts to your geometry, assembly, and integration needs. Die-cut shapes, adhesive backing, multi-layer laminations.
Standard Sheets
Stock dimensions, ready to ship. Multiple thicknesses across the full Skogar® range, available for prototyping and production volumes.
Custom Cuts
Die-cut to your geometry — battery cell separators, gaskets, complex shapes. Tight tolerances for serial integration.
Laminations & Assemblies
Multi-layer constructions, adhesive backing, protective films, encapsulation — engineered to drop into your assembly process.
