Ceramic foil faced blanket (MG) products, A, B and C arebased on our high solubility vitreous wool blankets which arethen reprocessed at our specialist manufacturing facilities.Aluminium foil and glass cloth are attached in a processdesigned to apply less pressure to the blanket surface duringapplication of the adhesive coating and foil/cloth. The resultingproducts are suited to use in fire protection applications, as avapour barrier in some furnaces and kilns, as a chimney linerin fireplace kits and as a light duty heat curtain.

General CharacteristicsCeramic foil faced blanket (MG) offers numerous advantagesand provide:• Excellent insulation• Good handleability• Re-usable• Fast thermal reaction times• Excellent thermal and physical stability

Classification Temperature is not a definition of the operational limit of these

products, especially when long term physical or dimensional stability is a factor.

For applications such as hot face furnace linings operational limits are generally

significantly reduced. In such cases please contact Sealumet office for advice.

A- Ceramic Blanket with a 30 micron aluminium foil bondedto one surface with a non-smoking and non-combustibleinorganic adhesive.

B- As for Ceramic Blanket B but with a square grid glassfibre reinforcing mesh added between the foil and theblanket. This product should be used with extra resistanceto tearing is needed. Ceramic Blanket B is non-combustible.

C- Ceramic Blanket C has a 230 gsm glass fibre clothbonded to one surface with a non-smoking inorganicadhesive. C Blanket is non-combustible and is ideal foruse where extra surface durability is required or if adecorative coating is to be applied.
