insulbar LEF: Low-E film as an alternative to foam

Ensinger optimizes thermal separation in windows, doors and facades using highly heat-reflecting film

Nufringen (Germany)/Istanbul (Turkey), March 15, 2016 - With a view to improving thermal insulation properties, Ensinger has advanced the design of its proven insulbar insulation profiles with a groundbreaking new technology. The use of Low-E Film (LEF) is reflected in the name of the new product: insulbar LEF. Applied to the flag of the thermal insulation profile, this film reflects the thermal radiation between the inner and outer shell of the aluminium frames used in windows, doors and facades. The functional principle is similar to that used in a thermos flask, whose mirror-finish inner coating maintains the temperature over long periods as a result of reflection.

insulbar LEF is a simple alternative to thermally insulating foam. When using insulbar LEF, the Uf values achieved are equivalent to those of thermal insulation profiles with foam – and in many cases even better. The rated emissivity of Low-E film corresponds to ε = 0.03 (standards and directives: EN 12898 and EN ISO 10456). This value can be used to draw up computed verifications in compliance with EN ISO 10077-2 and was confirmed by a test certificate from the Institute of Window Technology ift Rosenheim.

Frame system manufacturers can optionally use the Low-E film on all existing and new insulbar profiles with flag. The benefit: Only a single standardized profile design needs to be used. This eliminates the costs for additional extrusion tools. At the same time, the requirements stipulated in different markets can be adhered to without the need for a change of geometry.

insulbar LEF is supplied with a foil-covered flag and, unlike foam, can be directly further processed – without the need for additional cost-intensive work steps. LEF is heat resistant up to 200°C, is able to withstand this temperature for up to 20 minutes and so permits powder coating in the finished assembly. Standard anodizing is also possible. As an alternative to foam, using insulbar LEF permits significantly simplified processes.

Ensinger will be showing its insulbar thermal insulation profiles at the Yapi Fuari Turkeybuild from May 10-14 in Istanbul, hall 7, stand no. 151.

insulbar LEF: The thermal insulation profile uses Low-E film which reflects thermal radiation. This provides an optimum thermal separation of the outside and inside shells of metal frames for windows, doors and facades.
