The ultra-thin Low-E film 12 ε 3, which is applied at right angles to the thermal conduction direction on the thermal insulating bar flag, minimizes losses due to thermal radiation (ε = 0.03 in accordance with EN 12898 and EN ISO 10456) at windows, doors and façades, and has the same effect as insulating foam. The profile and film are heat resistant up to
200 °C (for up to 20 minutes) and unlike most foams, allow powder coating of the complete assembly as well as standard anodizing.
insulbar® LEF bars are supplied film coated ready for mounting. The laborious process of cutting foam fillers to size and inserting them is completely eliminated. The benefits: Increased productivity, a more reliable work process and no health hazard due to fine dust. insulbar® LEF profiles are suitable for wide-ranging requirements and systems. Because all geometries with flag are available ready coated with Low-E film 12 ε 3 directly from the factory.
In already existing systems in which insulbar® insulating bars with flag are mounted, these can be easily replaced by insulbar® LEF with no added tooling costs.
