INSULWRAP – DUCT LAGGING 2017-09-21T08:37:53+00:00

Insulwrap – Duct Lagging

Cross-linked, closed cell, expanded Polyethylene foam resistant to dilute alkalis & acids, some oils and weathering. Non-toxic and has good shock absorption characteristics. Fire Retardant.

Technical Data

Suitable for insulation of air-conditioning ducting. The closed cell structure ensures good insulation properties and can be protected with a foil laminate for concealed ceilings or wrapped in VentureClad if exposed to weather can be used on a wide range of other applications such as expansion jointing, seals and gaskets, packaging etc.

Black with reinforced foil face covering (factory applied).

Indicative average value.

Based on 90% supply average.

Defined as the temperature which will typically cause an average linear shrinkage of no more than 5% after a 24 hour exposure period. The percentage shrinkage of a sample, having the dimensions 100mm by 100mm by 100mm, with respect to its length, width and thicknesses is used to calculate the average linear shrinkage. The degree of shrinkage depends on the material type, density, temperature, exposure time, part dimensions and cell size. Other temperatures may prove to be limiting depending on the mentioned sample dimensions are to occur.

A 10mm thick sample is used to determine the horizontal burn rate of the relevant material. The above quoted value will be deemed not applicable, if anydeviation from the above mentioned sample dimensions are to occur.

The material will not combust for > 20 seconds after ignition source has been removed.
