Air Plenums/Combustible Items

New construction, building renovations or modifications to the electrical and mechanical systems may result in the installation of plastic pipe that cannot meet the minimum combustibility requirements defined in the Mechanical Code.

FyreWrap® 0.5 Plenum Insulation

FyreWrap 0.5 Plenum Insulation offers an alternative to complete combustible item replacement, often resulting in significant cost and time savings. It is a high temperature single-layer insulation blanket that is used to wrap the combustible items in the plenum area. It is an alternative to removal and replacement of the combustible item with compliant non-combustible versions by preventing flame propagation and smoke development in the plenum area.
