Microtherm® Overstitched Panel - Inn

Microtherm® Overstitched Panel
Versatile panels of flexible microporous insulation
Microtherm® Overstitched Panel
is a lightweight flexible panel of high
performance thermal insulation stitched
through on a parallel grid pattern and
designed to form easily around complex
shapes for optimised protection.
Microtherm® Overstitched Panel
is also available in a “semi-overstitched”
version which is a slightly less flexible
form that is stitched through in one
direction only. This makes it more
suitable for wrapping around cylindrical
shapes.
Properties
•Formulation based on opacified silica.
•Capable of continuous exposure to 1000 °C
(1832 °F).
•Up to 4 times more thermally efficient
at high temperatures than conventional
insulation.
•Microtherm® Overstitched Panel
is certified Class A1 to European Single
Burning Item (SBI) test, EN 13823
• Non-combustible.
• No respirable fibres.
• Environmentally safe.
Applications
• Insulation of complex shapes and
cylinders that would be impossible
to insulate with conventional
panel or block materials.
