Invented by TWI, BarrikadeTM is a novel, fire-resistant and thermally insulating material. It consists of vermiculite particles bonded with an alkali-silicate based binder.
The specific physical and chemical properties of BarrikadeTM make it a versatile material, allowing fabrication of shapes which have low density, are inert and non-combustible, and exhibit good thermal insulating properties.
||Rigid panels, moulded shapes, coatings
||Exfoliated vermiculite particles bonded with a blended silicate binder. (Alternative inorganic binders can be used)
||Open cellular structure
||700°C (continuous use; with a silicate based binder)
1050°C (discontinuous use)
||0.70 MPa (for ρ = 250 kgm-3)
||0.25-0.60 MPa (unlaminated*)
||Good (similar to wood)
* Laminating Barrikade (i.e. applying a skin of an appropriate material such as a metal or wood) produces a system with significantly higher strengths and extremely good toughness.
